electric bike

I am working on a motor bike that i had originally decided to go gas with but the motor dosent work anymore so i changed my mind and went electric. i was wondering if i would still need a jackshaft with an electric motor. it is a 24 volt motor out of  a powerchair.  i don't know specifics on tourque and hp, but it's pretty powerfull, and turns quite a few rpms. any help would be appreciated. thanks.

Electric bike generator?

I have an electric bike that has a 24 volt 450 watt motor, running on the back wheel.  would it be possible to fit a front hub motor  on the front wheel to ether help with charging the battery's while using the electric motor to run the bike or be able to power the motor when you have started to move.  If this is possible what size hub motor would I need in the front wheel and what modification would I have to make.

Help with electric bikes?

I am designing an electric bike (gas prices at $4 means I need one) and had a set of prerequisites to fill, and was wondering if anyone here could give me a quick hand. First thing is, I'd really like for it to have regenerative braking of some kind to extend the range, but am very unsure as to how to do this. I also plan on charging the bike at my school; so a built-in charging unit will be a necessity. I need a range of about 10-12 miles on a single charge, is this too much to ask? The plan is to use a pair of 12v 8 amp-hour Lead-Acid batteries (http://www.sciplus.com/recommend.cfm/recommendid/14608) and a 12vDC cordless drill motor to provide power. Is this too "weak" of a system? I have a 10-speed mountain bike that I'll be using as the base frame. Any help would be much appreciated.

Electric Bike Plans? Answered

Hey guys. I was thinking of building an electric bike this summer. The problem is I've never built an electric bike before and barely have any knowledge. I just wanted to know if it would be better to buy a ebike kit or to buy separate parts and build it. I have looked on Ebay for bike motors but i could only find up to 1000w kits for about 200-300 dollars and i thought that wasn't worth it. Is that the only price I can get a motor and do you guys know any good stores and sites to buy a cheap ebike motor. the other parts wouldn't be that hard to find so it's OK if you don't know of any kits. Thanks. P.s. I'm looking for Motors above 1000 watts

Electric bike motor help!

Helli guys.. after a long time racing motocross, I would like to experiment into doing an electric dirt bike for myself.. My plan is to find an 85 or 125cc frame with no engine, and build from that.. the biggest question is, what motor could I use that is no less than 15kw, and on the affordable side? I was looking at the Turnigy Rotomax 150cc eqiv. And it has a max power output at 9000 something watts, would that be any good for a motocross bike? Would it burn out quickly since its pretty small? Notes: i am strictly looking for powerful bikes, a 2kw bike is not for me since I am used to overpowered 250cc two stroke hell-born suicide machines, thanks..

BIKE GENERATOR?!

Hey, I'm much more of a mechanical guy than an electrical one, and yeah, I'm trying to be won over, but I think this project might help me bridge the gap if I can get it rolling. what do you guys think about buying maybe six or so friction light generators and disconnecting the lights, putting two on the front wheel, four on the rear, (they rub on the side of the tire) and wiring them all together to produce a power source? like I said, I'm horrible with electrical stuff- maybe you could even build a larger generator like I saw in another instructable, but do you think it'd be possible to either create a car-adaptor-style outlet, or even a functioning regular power outlet with that idea? what about an electric bike that charges itself while pedal in that sense? talk to me people!

Electric bike band brakes.

Hi all. A few weeks ago I asked on here about batteries for my bike and got some very useful input, as a result I bought a set of batteries from great dealer who was not only able to supply batteries matched to my bike but also gave me a remarkably decent discount and delivered them in two days, they cost me almost £40.00 less than the ones I bought a few years ago and the bike is now running better than ever. I now have another problem I'm hoping to get some help with, the rear brake on my bike is a band brake which I suspect has not been changed since the bike was new, it still works but not nearly as well as it should so it's time to replace it with a new one. When I rang the importer and sole stockists of these bikes in the UK about some other replacement parts a few months ago I asked about a replacement brake and they are asking the outrageous sum of £38.00 plus VAT and shipping for one meaning I would be paying out around £57.00. I know these brakes are quite common so had a hunt around the web and I have found quite a few with prices ranging from £5.00 to £19.00 but have some questions about size. The casing of the brake on my bike around the drum is around 4 1/2" diameter I have found various sizes available some smaller some larger but looking at the way it is mounted it seems to me that I could use pretty much any size I wanted providing the pitch between the two holes used to mount the drum on the wheel is the same, unfortunately none of the brakes I have found gives details like this. Does anyone know about these type of brakes and if the mounting holes are the same standard pitch on all the sizes of drum? if so would I be correct in thinking I could mount any size brake I wished? if I can I would be tempted to increase the braking power by fitting a larger one than it currently has. Thanks in advance for your help. NG.

Self charging an electric bike?

Hi all, I am always amazed at the ingenuity here and after many years of being fascinated I would like to ask my first question.  I'm thinking of getting or converting/building an electric cycle.  I've been told by local dealers that none except the very expensive have a recharge facility for sat when you go downhill or are freewheeling,  That seems a waste to me so I am thinking ... why not buy a used wheel with a hub motor and fit it at the front wheel and that raises the following questions in my mind ... Can hub motors be used in reverse as generators?   Would the output be speed (rpm) dependent and if so then if said cycle has say a 36 volt system would it only charge the battery if the 'generator' is producing 36v or close to? If so would it be better to find perhaps a 24v hub motor to use as a generator and charge the battery via a variable input, 36v output step-up? I appreciate it will be less than 100% efficient when both using electric at the motor and charging at the 'generator' but would anyone have any idea how inefficient?  I'm fit enough to cycle on the flat but would appreciate help on the hills!! I assume I will need a diode or similar ... does anyone know where I can find a suitable circuit diagram Lots of questions I know ... sorry. David

Thompson Classic/Euro Classic electric bike headlamp & mainboard wiring.?

Hi Folks. I have a bit of a dilemma I hope one of you good people can help me with. Nostalgic Girl asked me to get her old electric bike back on the road for her & all is going well apart from one small problem. Someone had a go at it a couple of years ago & managed to unplug most of the wiring in the headlamp where all the clever stuff is controlled like the horn lights & most importantly the speed. Normally this wouldn't be a problem as in a sensible world if you have six things to plug in you would use six plugs & sockets to wire it up, unfortunately on this there are six plugs but they have only used two different plug & socket sets one two pin type & one three pin type. Just to add insult to injury there are two three pin with Red, Green, Black and one with Red, Green, Yellow & the Two pin ones have two Black, Red one for the horn & another for the front light & another Blue, Brown which I believe is for the brake light. I would try a bit of trial & error work but I am just a little bit worried that the error bit may end up in my having to buy a new board. Can anyone tell me where I can get a wiring diagram from? Or know which plug goes where on the board? Thanks in advance for your help you clever people. Kev.

Electric bike from spare motors

Hi Everyone, my first post here.  I've been thinking of making an electric bike. Now there are bikes on the market that are $450+ and I have a spare one that I haven't touched in over 6 years lying around. With the recent improvements in DC electric motors, I think it's about time I gave it a shot at assembling an electric bike. The motor will likely come from an electric lawn mower, the battery will be a lithium ion battery rated for that motor (I can attach these into series or parallel depending on what motor I use). I've been looking at electric motors from Kogan.com.au (I'm australian)  Either one of these http://www.kogan.com/au/buy/18v-lithium-ion-cordless-garden-tool-set-3-piece-set/ or http://www.kogan.com/au/buy/recharge-mower-electric-lawn-mower The cheaper one more likely. If I should source a motor another way then I'm all ears.  My questions are: Would the motors in the first link be powerful enough (they use the same battery as an electric drill) How would I attach the motor to the bike so that I can ride and engage the engine when I want? How would I mount it so that I can use regenerative braking? I was thinking of using a clutch sort of mechanism attached to the wheel axle, again I'm all ears. And if anyone's done this already, what type of hazards am I going to face? (that probably aren't obvious, safety first!) I also thought of using a petrol engine from a lawn mower but an electric bike seems more appealing to me. :) Thanks all

Electric Motor Tricycle 6V4.5Ah

I bought a riding toy for my son and it's cool, but it doesn't have enough power sometimes.  It's fast enough in the house, but it gets stuck outside.  The plastic wheels tend to slip on rough surfaces and inclines, but I can address that issue at the wheels/tires to some degree.  However, the battery that came with it is a 6V4.5AH/20HR sealed lead-acid rechargeable battery (It has F1 contacts, so unless I change or adapt the wires/connectors, I think I need to stick with a battery that has these).  The AC-DC adapter has 6V DC 500mA output, but I think I could get a UNIVERSAL AC DC ADAPTER {1.5V 3V 4.5V 6V 9V 12V 500mA} that would work with a new battery. I'm hoping that I can increase the power noticeably but safely.  One constraint is the width of the battery area inside the "engine" compartment.  It fits the present battery (1.75 x 2.75 x 4), but I'll have to mod the compartment to fit a replacement that's more than slightly bigger. I've seen some 12V4.5AH batteries online, but most are larger in every dimension. Am I even on the right track thinking a higher voltage battery is what I need?  Could I use an NiMH or Li battery/batteries instead? What's the easiest, safest, cheapest route for this mod? Thanks, Dan

Hello all, i am building an electric bike (basically converting my old bicycle which is useless into an electric one) and figured that no one could be a better help then here at the instructables! ;D anyways, so i am using a 24v 250W motor along with 2x12v 12Ah sealed lead acid connected in parallel (in my country it's almost impossible to find a lipo4 or lipo battery for that matter). i reckon i should be able to get 30kms out of the batteries. so first of all i needed to know if this could work out for me (btw, it's not a hub motor it looks like this: http://i02.i.aliimg.com/photo/258897322/DC_Brush_Motor_XYD_6D_v0.jpg) but, more importantly what i want  to know is that i since i can't find an electric scooter controller over here, would it work if i could connect a electric thumb throttle (or twist throttle) in series between the battery and motor on one side, sort of like u connect a normal fan regulator or switch by cutting either the +ve or -ve wire in half and putting re connecting the wires through the switch, like in the picture below (sorry for the bad diagram), so, thanx in advance, any help will be appreciated and please reply asap as schools are starting and i have to be done before the vacations :P

The switch also locks the battery box onto the frame it looks similar to the larger of these two on ebay. I have called the importers & their quote for a replacement carries an outrageous price compared to the third party ones I have seen at over eight times the price plus postage & although I expect to pay a bit more for a slightly more complex part I certainly don't expect it to be THAT MUCH more.

Increase the speed of an electric motor? Answered

My electric bike, seen here, was built for my senior project. I was limited on motor choice, and had to go with the best I had, an old powerchair motor. After 2 successfull attempts at building an electric bike, I have discovered that it is impossible to go faster that 25 mph with with one of these motors. As you can see on my instructable the bike has 6 speeds, with a top speed of 20mph in first gear. however, when I shift gears, the motor rpm's decrease instead of the speed increasing. I have heard before that it is possible to run an electric motor at higher voltages than it is rated, so I was wondering, if i could add a seperate switch and a "booster battery" of sorts, that as long as I monitered the voltage so as to not let exceed 24 volts, if this would be feasible. My only other option would be to add a second motor in parallel with the first, and on the same drive belt. The first option would be the easiest, if it could work without damaging the motor. Any help would be appreciated. Thanks, iloveairsoftstuff

And sixth.)I've wanted to build an electric bike or a recumbent for a long time, but despite fiddling with bikes for a while I'm still just a competent novice. A competent novice with very limited tools, in fact. Therefore I'm looking for a project like this uber-simple electric-assist (incomplete) or the no-weld recumbent. If anyone knows of any other projects like these, I'd like to see them.Pictures of the bike to follow- it's a fairly generic short-frame mountain bike, probably intended for dirt jumping as it's got a short geometry, thick downtube and a low seat/short seat tube. The front fork is a "suspension" fork with about 1" of travel and too much preload to be any use on roads, everything else is standard.

Does anyone have some suggestions about how to wire them all together? I was looking at This Movie Earlier and seems they used 30X 18650 cells to build a 37V battery pack My biggest concern is balancing the cells. since 3 are wired in parallel (then 10 groups in series) it seems to me that each cell may receive a slightly different charge. I'm trying to find a 9-cell balancing charger but no luck quite yet. Even if I do, does anyone think that will cause an imbalance in each of the three cells wired in parallel? Also each cell has some sort of an over discharge regulator on it as well. I'm wondering if they would be a factor in charging/Discharging the cells.
