Dirt bike handlebars

Hey everyone, i have a 2003 XR100 four stroke Honda dirt bike and I am on a quest to transform it into a beast hair scrambler trail bike. So far I have decided to add bark busters, one of those bendable hinge shifters, a back sprocket with one less tooth (will be 49), a new front sprocket because the teeth are bent, I need to sharpen the foot pegs and brake peg, a new back tire because the one it has now is bald, and shorten the handlebars. The reason i posted this forum is because i am wondering if anyone can tell me what the best way to shorten the handlebars is. I figure i am going to loosen everything, take it off, measure 4 or 5 inches with a permanent marker, then grind it off, but i dont know how to get the grips off. will i need to buy new ones? any way, if anybody can tell me how to shorten the handlebars, i would be very thankful. also, if anyone thinks i need anything else, could you please mention that too? thanks!

creative bike handlebar grip ideas?

I'm looking for creative solutions for items to use for bicycle handlebar grips. I often get alot of bikes/partial bikes from people and end up fixing them up and giving them to friends who need them or trading them for other bikes, but the problem is that most bikes I get are missing the handlebar grips, and I don't want to spend 5-10 dollars on a set of grips just so I can give the bike away. I would like to be able to go to the hardware store and buy the objects in bulk for pretty cheap. Just post ANY ideas you have, thanks.

can i make my own bicycle-light housing out of silicone?

For some small projects like a bicycle light housing, and selfmade handlebar-grips i am searching for the right material to use. i was thinking about using some kind of rubber-like material, probably silicone, so i can wrap it around the handlebar. unfortunately there are many different kinds of silicone to buy, all with different physical and mechanical properties - so i would like to know what silicone would be best for that project? or should i use something else? it should withstand moderate tearing while mounting, and should tolerate rain and sunshine, etc... thanks for your help!

How can I disassemble an old bike's fork?

This week I started restoring an old 1980's esmaltina bike. I started stripping down the frame so I could paint it. After removing almost all the things in it, I begun removing the fork, so I could later paint it and chrome a little piece on top of the fork. BUT after 3 days of constant aplication of WD40, hammering, sometimes heating prior to the hammering and it hasn´t moved anything. How can I remove it? Please help me! This is the foto of the bike prior to me doing anything to it. I also don't know the model, but I believe it's an A SS model. If you know what is it please tell me (keep in mind that isn't the original handlebar, the orinal was one of those horn style racing handlebars)

Wacky bike?

You know at carnivals they have those "wacky bikes" Ride it like 6 feet or so and you win a little pocket motorcycle. I would like to make one. Not sure where to begin or if this is easy enough for me (I have no metal working tools other then a dremel and a grinder). Basically, the wacky bike is a bike that when you turn the handlebars left, the wheel goes right.

A few questions for recumbent bicycle makers

Okay, as the title says, i've got a few questions for anyone who's made a proper recumbent bicycle. First: in the way of moving the handlebars back, how do you attach a bicycle chain sprocket to the top of a fork tube? is it welded? or is it a special type of sprocket with a sort of crankshaft keyway (like engine crankshafts have keyed sprockets for their timing chains) this is obviously to relocate the handlebars further back or under the rider so that you can lean back (as most recumbents allow) Second: if you're to put a larger tire on the rear of your bike (for example, a small (50-500cc motorcycle) rear tire), how would you go about converting the chain link sizes. most motorcycle tires have a shorter link distance, and look like their links are sort of squashed together as opposed to bicycle chains. would you find a way to put a larger toothed sprocket on the rear tire or put a smaller toothed sprocket on one side of an intermediary and a larger toothed on the opposite side? If I have any more i'll post them, these are my pretty basic "burning questions" of recumbent making.

I want to mount a couple of LED powered bicycle headlights on the front, and a tail light on the back. However, I want to be able to turn them all on and off via a single switch, mounted to the handlebars.I know very little about wiring, but I do know that most bicycle lights require physical pressure to power them on or off. Maybe there's something that can go between the batteries and bulbs?Any input you can provide would be fantastic!-Ryan

Suggestions requested on attaching Creative Travelsound to bicycle

Hello. As someone who's moved to a bike friendly city, sold his car, learned the intricacies of mass transit... the thing that I miss most about my car is the sound system. Mind you, it was stock, but it was still good enough for me. Well that, and not getting wet when it rains and when the road is still wet. I'm not interested in being the obnoxious jerk at the stop light forcing a 1/4 block to listen all the bass I can afford, I'd like to put together a non-headphone sound system for my bike. I have pictures below of the the three components I have at hand. Jamis coda sport, creative travelsound battery powered speakers (which eats batteries like they are going out of style), and Zen V touch mp3 player. my goal is to have a personal stereo that is quickly detachable, yet secure, and potentially offering improved FM reception by 'hardwiring' an antenna to the frame. upon initial inspection, i suspect the easiest way would be to have a granny basket off the handlebars and just throw it into there. So that's my fallback plan. But there are some geniuses that peruse this site and I'm interested in how they'd attack this. two things to note- while my handlebars are flat, i've rotated the bar that holds them to a 45 degree angle. Also, the travelsound speakers are attached at the base that hinges with the battery pack. It's not that obvious in the picture. Thanks for the help with this.

Bicycle iPod dock

So here's my idea: I'm restoring an old bike and there's a spot for a fake gas tank to go. I will build this tank, but one side will open up and hold within it an iPod dock. At least, I'd like it to.  I'm thinking of using the pedals as a dynamo crank which would power the iPod and play music through speakers mounted on the handlebars. I've been doing a lot of research and it seems possible, however, I've not done something like this before and I was wondering if anyone would have any pointers on how to make this work well. P.S. A separate USB port would be cool as well, so that a phone could be charged while riding the bike.  Thanks for your suggestions!

50cc Chinese scooter problems? Answered

I have a 2001 Chinese scooter, 50cc, and it has some problems... We took the handlebars off to fit it in a vehicle for transport (Yeah, stupid idea, I know now...), and now, the wiring is all messed up. First off, the electric start won't work anymore, I'm going to go through, and check a relay and the battery voltage tomorrow. Second, when I kick start it, and yes, It'll kick start, but only after 50 some kicks.. But when I kick start it, the engine starts going full throttle, but the throttle is not twisted at all. Throttle cable problem? Lastly, the turn signals are messed up a bit. The right blinker flashes one of the headlights inside of the blinker.... What the hell? All the wires are connected correctly. Please help!! Thanks!

I need to put rear brakes on an adult trike. Any help?

I purchased an old three wheel bicycle from a local secondhand store. It's in great shape, except the fact that it is lacking rear brakes. I haven't had any success in searching for plans, so I was wondering if anyone had an idea or (better yet) previous experience with rear brakes on a trike. I was hoping for a great way to run both rear brakes from a single brake level on the handlebar, and there aren't any forks around the rear tires to attach brakes to, so I guess I could use some help there as well. The rear conversion kit looks similar to the one here. It's a small picture, but it's the only accurate one I could find. Any help would be amazing. Thanks in advance.

Jake the Peg Halloween prop

I'm looking to create a hinged leg to use in a "Jake the Peg" Halloween costume prop. If you've never heard of Jake the Peg, here's a link  to the famous Rolph Harris skit. I know he's using a false hand on the right side (his right) so that he can control the extra leg, but I'm unsure on how to create the hinged effect. (It's the bending of the leg that makes it so realistic!) I was thinking of using something like a bike handlebar end with a handbrake lever to pull a cable that would draw the leg up, but how would I get it to spring back to the straight position? (And when it's in that position, it would need to support some weight like a cane) What should the leg be made of? There has got to be a better way to do this. The illusion is fantastic, but there are no articles anywhere on how it is done. Thanks for any help anyone may have.

Simple Bluetooth remote control

Hi everybody. This is my first post so thanks in advance if anyone answer me. My question is if somebody had seen some kind of remote control, working via bluetooth, with a couple of buttons, that send  some instructions to an android (Example: play/pause, next random song, etc..). I personally couldn't find any in instructables. I think of this when i made a long travel in motorcycle and i play music on my cellphone and one of those little speakers in my jacket (at a moderate volume) to entertain myself during the travel. So it would have been very useful to have a simple button attached at the handlebar to skip the song or pause it for some reason. So it would be great if you had something like this on your archives, or give me a clue for what i need to look for to make it. Thanks again. Best regards  PD: btw i don't speak english so i put an effort redacting this

Vacuum pump voltage?

Today I was dumpster diving and i found an old vacuum so i decided to take the pump out but i made the mistake of not checking what voltage the vacuum runs on, because it also had a spinning component at the mouth of the vacuum. I think the pump works fine because i noticed that tube connecting the mouth of the vacuum and the pump was broke. Is there anyway to find out what voltage it runs on? would standard 120 be ok?The markings on it say 81 b-9 ECP 6500-240 HPU+ 60hz HD10 120 vac 07:07 does that mean it will work off a standard 120 outlet?update: What I am going to do with this motor has been decided. I will be attaching it to the back wheel of my bike with a car battery, i will install some type of switch on the handlebar or add something like a dimmer switch, this would allow me to have the motor on if i want, and i can adjust the speed. Please help fine tune this idea.

bike booster kit

There is a project here on how to build a "BIKE BOOSTER KIT". The kit is made up of multiple 3d printed parts, including the battery pack, charger, test equipment, and a choice of small or large rc notor. The built kit is designed to mount above the front tire either bike or trike. Although I do not know what kind of bracket is included for mounting. It can be configured to fit in a bike frame in any number of positions as long as the roller can touch the front tire. I plan to mount this on a trike, There are only two possible locations, on the handlebar stem, or the fork center hole for the fender after fender has been removed. I need mounting instructions, user manual, premium hardware kit, any special mounting brackets, and sources as to where I can buy a fully assembled kit charged and ready for mounting. I am concerned that the unit is not long enough to reach the tire from the stem. I might need some sort of extender block to make it longer. Complete advice please. reeltoreelguy@gmail.com.  photo included.

How I turned my Huffy BMX into a great stunt machine- and a question about decals

An ongoing project- the lost Huffy.chapter 1- Why people will think this is funnychapter 2- How I got itchapter 3- How I did itchapter 4- a questionChpt 1- Why people will think this is funny-Huffy is known(alledged) to be a cheap crummy Wal-Mart bicycle. I have a limited budget. I turn cheap crummy Wal-Mart bicycles(alledged) into great stunt bicycles.Chpt 2- How I got it-I was riding my bike, a six speed automatic, to school, and saw something reflect as I went by the weeds. I stopped, because I go the route almost every day and never saw anything reflect, and what should it be, but the most destroyed Huffy Rock-It I have ever seen in my entire life. I went on to school, as I was runnimg late and don't have a cell phone(I don't want a tumor). At lunch, I came back. I went into the Snak-Shak, and called the sheriff using a pay phone. Well, I waited. And waited. Lunch ended, so I left a note with my contact info at the scene, and left. At three, I came back. It was still there, note and all. I went home. Waited. No phone call from police saying they found the owner, nothing. Seven o'clock. I hitched a ride with my neighbors, over to the scene, and I got the bike.Chpt 3- How I did it- The handlebars were bent back at the stem in a 90 degree angle. I took them off, easily, because they were so busted that all I had to do was jiggle them a little, and they came off. After several attempts at riding without a handlebar, I got one off another frame I have. They wouldn't work. So I got the handlebars off another project(that failed)- an older Next Wipe Out that had been run over, bent frame. I put them on, and they worked great, apart from some adjustment issues- the rusted bolt needs replaced. I aired up the tires, and sat down. Painfully. Old Huffy seat, narrow as heck. I left it on there for for a while. Then, I thought, and thought, and finally asked what I should name it. So, Phoenix, arisen from the ashes of destruction, was about to be made into a really good bike. I recently replaced the seat with a plush, comfortable seat from a brand new (yet busted, due to cheap manufacture) Mongoose Rebel, but for the sake of the budget, the Bell "Little Rider" seat is as good or better than the seat I used. I only used that seat because our Wal-Mart sold out. I rode around, and it worked out great with the parts I had so carefully picked out. Things still need to be replaced, like my front tire, shaped about like this- ), and the pedals, I'll use the Wal-Mart kind. Pegs, also from the Wal-Mart, but I personally don't want pegs, as people tend to jump on the back of my bikes as they are, with no pegs, and I don't do those kinds of stunts. It rides great, except some things need a bit of oil, and just yesterday I adjusted the chain incorrectly, and now I'm in lots of pain from it locking up and throwing me off. But I fixed that, and am thinking about stenciling her name onto the frame.Chpt 4- A question-How do you get the decals off the frame? I sat there with a hair drier for about an hour and got a quarter of one off, but that's to slow, and is very uncomfortable. I want to stencil her name onto her.

Well guys I finally ran out of luck

On my way to work today I came off my bike at somewhere around 20-25mph, on a long sweeping corner I was turning with a steady lean and just lost all grip, both tyres slid, my left elbow hit the ground, shredded most of the skin on it and I actually brunt a hole in the jumper I was wearing with friction, I flipped over and smashed my wrist in to the ground so hard that that doctor wasn't sure if it was a sprain or break due to swelling, at some point my left hip hit the tarmac and they Xrayed that aswell in case I had chipped it, there's a nice swelling forming there... I also scuppered both my knees, the bad one is now just popping out from under me at any oppurtunity while the other can barely be moved. I've also just noticed that theres a bit of wood or stick stuff in my arm. This means that I can't go cycling for two weeks by docs. rules, can't play guitar hero, can't lift anything, might not even be able to drive, which would suck nuts as I just started formal lessons, finally afford them and I'm put outta work for a week and can't use my time to do the stuff I want/need to do. On the upside I can get to the hardware store and get my pulse jet parts and be doing something with my time, but I wont be able to build both because I've to save extra wages for next month as I wont get my days off back. The bike stood up to the crash much better than me, scraped paint on handlebar bell and I somehow knocked the reflectors of one of the pedals, I'm guessing thats the big gash on my shin explained... It's wierd I've been hit by trucks and got up straightened the handlebars, cycled off happy enough, I had the same type of crash except the front wheel fell down a curb I clipped a car and hit a wall with enough force to damage it and was fine apart from minor bruises, this simple crash screwed me completely, I fell perfectly and rolled well after flipping and smashing my right wrist, the bike somehow got a good distance away from the crash, as did I... Also three instructables I was planning will have to wait for at least a week, depending on what tools I can manage by then, it's a shame I just made three great projects and I have to wait until I'm better to finish them and publish... it also took me about 25minutes to write this...

Recumbent Riders?

Just curious if anyone else here rides a 'bent. I've just been getting more and more excited as I continue looking for my own :) I'm currently in the market and have test rode a Bacchetta Strada, Volae (something or other), Rans Rocket and a no name unknown import SWB. I'm also waiting to hear back about a partially built M5 frame (think "sports car" class of 'bents). And don't forget my homebuilt abomination :D Today I rode a no name something or other found on Craigs List... In my home town too! It's not exactly what I'm looking for (it's too recreational for me), but almost exactly perfect for my father. It's got absolutely garbage components, but I see potential in it. It is, however, a dog on weight - ~40 pounds. But that's not an issue because there's no hills :D The seat is also a POS, so never mind the makeshift seat back made from bike inner tubes. <--- totally awesome by the way. But I think with a new seat, some cable management, better handlebar/stem and at the very least - new shifters -- it will be fun, reliable and a more road worthy 'bent. The price was right for this thing too :p Cheaper than an upright from walmart :D

Extending a mobile phone's camera away from the phone by adding some longer cable?

I have a little project where I am looking to extend the mobile phone's camera a few meters away from the phone while still being able to use the phone as a viewer. I would like to use the camera and the phone because the power source is already set up, the camera and the phone mesh without trying to add a camera to a small LCD screen, and I have loads of old mobile phones and was hoping to be able to recycle one or two of them. I would like be able to place the camera of the phone a meter or two away and be able to view the video on the phone. This could be useful in looking in hard to reach places within reason. I could also maybe set up a little rig for attaching the camera to my motorbike helmet and recording without strapping the entire phone to my helmet. This could also maybe be used for making a little rear view camera for my bike by placing the phone on my handlebars and routing the camera behind me. I know they sell back up cameras, but again I am just looking to find a use for my mountain of phones. I assume I would just need to find the camera's cables and extend them, but I am also going to assume they use a ribbon cable. I was just wondering if anyone knew of a way to extend the camera away with a bit of wire soldering or something along that nature. Would the mobile phones with VGA cameras use a system other than ribbon cable? Hopefully someone can wrap their head around what I am describing and help out so I can find something useful do something with a few of these outdated mobile phones!

Motorcycle communication without expensive BT headsets!

When it comes to communicating with the person on your back seat then often there is no need for a fancy BT headset.Unless of course you are constaly driving on freeways at high speed and love to talk ;)The most annoying thing though is when you want to go for a long ride with a lot of your mates.Some might already have some BT headset, most might not have anything to communicate.Even with just 8 or 10 riders in your group, loosing one is easy.The most advanced headsets now offer functions for automatic pairing when the connection was lost - they come at a price though.Around here there is two problems to face when going for long rides.a) communication range for the riders in the group.b) cellphone coverage is usually non existing when you actually need it.So why not go with something totally different and much cheaper than BT headsets?At highway speeds the range of BT headsets suffers not just from the required safety distance between riders but also from the spped itself.Cheap headsets just crap out all the time, expensive one tend to loose the connections quite often.Wouldn't it be great to have more than the average 800 meters of good sound quality without dropouts?And if you ever tried to have a decent converstation with another at high speeds you already know that even the best BT headsets struggle with the wind noise unless you have a really optimised helmet (and paid a lot for it).The alternative, if we trust all the hype and advertsiements would be to go for the latest generation of headsets out there....Baofeng UV-5 series....This type of UHF/VHF handheld radio has ben around for years.It is not only quite cheap but also able to put a full 4W out.So called battery eliminators to power them directly from a 12V socket (in your car) are cheap as well, but a good battery should last for a few hours.The benefit of these cheap radios however is not that they are so cheap.It is that you can actually program whatever frequency you like for your needs.Of course you should stick to the frequencies and channels that are free and legal to use in your area.The since is about what a pack of smokes is, so no problem to mount it descreetly on your dash or handlebars either.Being a radio there is no need for pairing or making sure you stick to the correct order when doing things.If you want to be "alone" on a channel you can even use celectcall and other option to make sure only those radios with the right callsigns wil open your squelch.Quite nice if you suddenly get into an area where your channel is used by ther people.Ok, a handheld radio might work, but what about the antenna?The UV5 series usually ships with two antennas.A short stubby that is good for about 1-2km - line of sight.And a small external antenna with a magnetic base.On a bigger bike it is often no problem to add a 15x15cm plate behind the seat that the antenna can pop on to.Should only be required if your require a bigger distance though.And why would a UHF radio be any better with the background or wind noise?Biggest problem with these expensive BT headsets is that you need to get really creative if you want to change the speakers or microphone.And options are quite limited here again - either a flexible microphone or a glue on one.Neither is really good once the wind gets too much.For the UV5 series you get so called throat microphones for under 10 bucks.Often advertised as tacticle headsets but for the price nowhere near the quality of a military grade combination.They plug straight into the handheld and come with an external push button that can be used to start a manual transmission.But of course you can automate this on the UV5 as well by selecting the voice activation mode in the menu.Set the level so high that you need a slightly rised voice to start the transmission.(That way not everyone needs to hear you swearing about other drivers if you keep it quite ;) )All up a solution like this will cost you well under $100, with all required extras.For a bit more you can also get UHF radios for helmet use.Basically the same like the handheld option, but smaller, a bit more convient to use and set up but also very limited in range and battery life.

Help for completion of Knee Walker Project ?

Hi Everyone I have a problem with a project I started to overcome my unique disability , this project was to basically install low powered electric motor on a kneewalker so I could get assistance / go off-road , yet still use it manually if need be i.e. to get some exercise or more importantly if battery dies ( something I cant do with mobility scooter or wheelchair  ) The problem however is I cant do this myself due my disability ( weld it , use power tools etc ) so I had this person i meet on a another  forum who agreed to help me - but unfortunately he hasnt   - so instead I am trying to find a replacement for him or any one that is willing to help. The motor itself ( Motor - MW12B GoldenMotor  )seems to work fine using a Lyens controller , but  unfortunately there is no direct link to the hub motor whose details are below. Model: MW12B -- 12" Motor Wheel Voltage:36V (Brushless) Power Rate:250W Weight: 4.8Kgs You will have to got to the gm website on the link above click on hub motors and scroll down to find more details , including links to 3d drawings . You can see the motor itself working in following videos that were posted by the person who still has it video1 video2 video3 Due to the size difference of the wheel  ( 16" compared to the front 9" using MTB tires ) amongst other things, we were  trying to find a way to mount it that he suggested would probably involve having to weld on some strong rear forks from a bike  or perhaps something else. Ive included the whole assessment / plan we did based on our mutual ideas and discussions below for reference, but Im afraid thats pretty much it , as I dont have any of the parts here for reference or than the basic facts . If any ones interested in helping , or going me any advice Id be grateful for your suggestions , if any ones wants to offer their services at a price just send me a pm and we discuss things further. thanks for listening , heres the assessment / plan I mentioned.. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- I need to figure out a rough plan for the wheel mounting, plus brake mounting. We need to get disc and caliper. We need to figure out what front wheels, how to mount them, and how to fix the sloppy steering. In order to go see a welder we need to know where to weld the dropouts, the caliper mounts, and what, if any welding to do at the front end. Assessment Frame - good, solid, heavy. bulletproof. Wheels - strong, solid, better made with bearings etc better than expected. but hard tires are not nice, and wheels are a little too thin and too small. I expect its easy to get hung up on small obstacles. brakes - crap. none existent basically. Just a bit of metal pushing on the tyre. Also the lever is either crap or a bit broken. need to inspect it. steering - not very good but not crap. whole linkgae is a bit loose and wobbly, just held together by a few bolts. this means it has a fair bit of play in the steering. The whole thing with the bolts is that they have to be a bit loose otherwise the steering won't move. not a very good design. but it will do. handlebars/stem/steerer - designed to be collapsible easily, which is good, but there is also excessive play in this as well. it will do but its not great. ------------------------------------------------------------------ Thoughts.... Because there is four wheels, I found that on uneven floors (just around the front room the floorboards were uneven enough) one wheel is often off the ground a tiny bit. This would be solved by having 3 wheels or tyres with a bit of give in them. I would not want to keep any of the wheels. I would want to replace the front wheels with something a bit wider softer and grippier. like scooter wheels or MTB wheels. Brakes - the center of gravity is quite far forward. if it had brakes only on the front then i feel like it might tip over. then again, with the weight of the frame, the motor, batteries and person, maybe not. I will do some testing. Motors - Golden has the 8" single sided solid tyre motors that would be the easiest conversion, but I don't like the solid tyres and I don't like having 2 wheels at the back. I already ran into my foot. There is also the 8" double sided solid tire. This is not so easy either because it is the same size as the existing wheels therefore the axle would want to go exactly where the existing axles join. Could be done with cutting and welding but would be a pain, plus you still have the solid tire etc. I held up a 12" dinner plate and I reckon it would not look so bad actually. I will take some pics tomorrow. It looks like we would need to cut off a bit of the back section and weld on some dropouts, a bit higher up and further in than the existing axle mounts.. It looks like it will fit under the knee platform ok as well. Controller - because we may well end up with a motor that is not exactly right for the job, I think its all the more important we get a controller with some intelligence. Something programmable where we can set a low voltage, top speed etc. This leads us back to the GM controller, Lyens mini monster, or......I just thought, hmmm the kelly controllers are programmable - well they do a little controller that might be up for the job as well. In fact it looks the most programmable one so far. It is the mini one next to the coke can here: Hub & Wheel Motor Controller | EV Parts They have one that does 12-24v for $79 or $99 depending on max amps. You can get it waterproof for an extra $19 http://kellycontroller.com/kbs2405120a1 ... p-499.html It is fully programmable, see the software screenshots and manual here: Kelly KBS controllers online demo/help-Kelly Controls, LLC http://kellycontroller.com/mot/download ... Manual.pdf You need a serial port on your computer to program it, if you don't have one you need a serial to USB converter. They sell one for $29. Kelly are good controllers. I never thought of them until just now - I usually associate them with high power controllers for cars and motorbikes. When I used to work at Sevcon (who make argubaly the best...and most expensive...controllers you can get.)....kelly was one of the few competitors we kept an eye on. If you look at the setup software, you can fine tune min throttle, max throttle, max amps, max speed, all kinds of things. It will be just the ticket for fine tuning. --------------------------------------------------------------------- So........... This would be my personal plan right now - Electronics: $115 Motor - MW12B (GM) $98 kelly controller waterproofed $29 Serial RS232 to USB converter (from kelly) $20 throttle (max) $20 ebrake lever (max) $50 wiring, connectors, etc -------- $332 Frame / Fabrication: $50 old steel bike to steal dropouts off (maximum, probably less from craigslist or a garage sale) $150 to pay someone to weld the dropouts on and maybe brake caliper mounts plus machine front wheel mounts if necessary for new wheels (maximum) $50 (max) 2 front wheels MTB or scooter 8 inch with pneumatic tyres. $30 (max) new axles, bolts, washers etc $30 box for battery plus mounting bolts etc $50 (max) for respray or powdercoat frame (will be messy after welding. something to put the battery in ----------------------- $360 Brakes $20 (max) brake disk for rear plus screw on adapter for rear hub Brake discs $40 (max) brake caliper (cable ok, hydraulic not needed) $50 bolt on brake caliper mount (seen them somewhere but can't find right now) price is a guess. --------------------------- $110 Battery depends. I am clueless as to the requirements of this system. I can test with my own batteries once it is setup. Then we will know, but at a minimum you will be talking about 18 or 24v 10 amp hour. That is : $199 from ping
