Bike to Trike - Bike Axle Replacement

Along with other minor changes to my bicycle, I really (really) want to turn my bike into a tricycle. I figure having one front wheel and two back wheels would be the best (and by best, I mean simplest) arrangement. I'm also guessing that it would be fairly easy and perhaps weld-free. I want to get metal tubing/a metal rod that is the same size as my back axle, have it be about 4 feet long, and place two wheels on either side. The gears would be located in the same spot they were, just attached to the axle and not the wheel. I don't know how thick my axle is, but I can figure that out - the problem is, will the axle hold my weight? I plan on also loading some cargo (add, say, 50 pounds). I don't think the cost would be too much (over $50?) and should I need to weld something, my brother might still be able to do it. Do y'all think this would work? Would the axle hold 250 pounds of weight? If so, the axle could be threaded on the ends so as to keep the wheels in place, right? Thanks!

LED bike tires

We've seen all sorts of ways to light up your bike. Here on Instructables people have used LEDs, cold cathode lights, and even fire. Now a company called Cyglo is making new tires that light up with LEDs. They are powered by the spinning of the wheel. When the wheel isn't spinning you can see the individual LEDs. They blur together when the bike is moving for a persistence of vision effect. They're not on sale yet, but hopefully soon. And then there will be one more way to be brilliant while riding at night. Cyglo Night Bright Tyres turn on the magic of colored light

Unfortunately, when I got it all put back together and test rode it, the bike had a nasty pull to the right. Bent Frame. He didn't check that when he bought it (didn't know anything about it, I daresay).  Anybody know anything about repairing a bent frame? The frame's tubes don't seem to be damaged or crimped or dented.  I'm thinking of using a car jack and some straps to straighten it out. Any thoughts?

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!

Bike pump problem?

I was using my bike pump today to fill a pneumatic launcher, and finally I just got fed up with the leaking around the pump base. On every stroke, the first 3/4 of air would be leaked out of the base, and it would only compress the remaining 1/4 of air remaining, and that would only compress if you pushed down very hard, and quickly, otherwise it all leaked out. And no matter what pressure the launcher was pressureized to, the pump handle/piston would slide down slowly, getting pushed down under it's own weight, meaning that there was almost no resistance to it. I think the leak is occuring where the tube meets the pump base, and you can feel air rush out with your legs as you pump. I'm pretty sure there is a one way valve in the gauge portion of the pump, which connects to the base with a hose,  and the filling hose is coming out of it, which is allowing me to compress at least a little air before the rest leaks out. I disassembled  the pump, starting with the base. Turns out, the leak was from an oring on the tube which was not tightened down enough by a screw on ring around the base of the tube. Put it back together, and voila, pushing my finger against the schrader valve connector and pushing down on the pump handle created pressure against my finger and no leaking. As soon as I hooked it up to my launcher, i realized something was up, I could pump down once, but the pump handle just got pushed upwards as soon as i let go. This is what I can't figure out how to fix. It seems the one way valve in the gauge portion is locked in the open position. Anybody know how to fix this? EDIT: Okay I took pictures of the pieces. I now cannot figure out if the valve is in the base, or the gauge portion, so i have included pics of both. Hopefully someone can help me figure this out. EDIT 2: Turns out the valve is in the base, and the ball just fell out when i first disassembled it, i have now found the ball and it is working fine.

Folding Bike Wheel Invented

Traveling with bikes can made easier with couplings and taking it apart, but the wheel has always been a solid item that has to be worked around. This might not be true in the future with this new folding wheel that is made up of six segments.This design by Duncan Fitzsimmons is being looked at by major manufacturers, or so he says, but no matter what it will take a while to come to market and likely cost more than all of my bikes combined. I can only hope that these eventually do some out and the economy of scale makes them only mildly ridiculous in price. link

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..

Series Hybrid Motorized Bike

I am designing a system to motorize my bike, but I really don't have enough money for it. I have been thinking I would like to use this engine for quite a while, because it's cheap, light, and OHC. There is a centrifugal clutch for it, but it costs $85, so I've been trying to design a series hybrid system instead. Considering that these motors cost only $6, it seems perfectly feasible to make something cheaper this way, but there are ways I can think of to possibly make it even cheaper. Here comes the technical part: my original design has two of the motors hooked up to the engine at double speed as generators, making 12v. Then there would be two more of these motors traction-driving the rear wheel. The problem with this is that the gear reduction is expensive. My new design has the engine directly driving only one generator, making only 6v so that I would have to have as many as 8 motors driving the wheel (opportunity for AWD?) to pull enough current to get full power out of the engine. Here's the problem: I don't know if the generator will be able to handle that current draw. Considering it would only have to do it for a couple seconds, do you think that one of these motors (working as a generator) could handle 400 amps surge? Other information: this will not see much low-speed operation. Geared to top out at about 25mph, it will probably spend most of it's time going 10-20.

Feedback-Clarinet Bike Concept

Not sure which forum this would fit into most effectively so I placed it here. I have quite a significant number of junk clarinets and I am looking to make/decorate a bicycle with them. It would clearly not be safe to make the frame from clarinets so I was thinking Id build it off of an old, black frame. The question comes down to construction. I am not sure how I would go about doing it. The inside of a clarinet is too narrow to slide down a bike's frame even if you could get it there. I considered drilling out the middle then cutting it in half in an attempt to affix it to the frame, but Im not sure. The other consideration was to remove all the metal pieces from a clarinet and attach them to a black frame in a manner reminiscent of clarinets. I also considered a variety of accessories, reed themed basket, clarinet-bell horn, etc. Any thoughts on the concept, additional ideas and/or ideas about the construction. Thanks!

diy elec bike assist

I guess I need to explain that I'm an old guy with a bad ticker. I also have some big time balance issues. I needed to get a little more active and work on my balance, so I bought a bike. The bike is about a million year old cruiser, so I had some work to do before I even took off on it. I cleaned and repacked everything. Then I switched out some parts to make it more comfortable. I replaced the sprocket drive set on the 26 inch bike with one from a 20 inch to make the peddles easier for me to reach. I also used the smaller drive sprocket. That might not have been such a good idea as I have to peddle more to get the same distance. I had intended from the start to install a helper motor so the pedal thing isnt really a big deal. I designed it this way. Motor: 24volt 250 watts from a kids scooter toy. drive: friction with a wheel that sits on the rear tire. Now the motor and mount I have worked out just fine. I'm waiting for everything to arrive so I can begin work. My question is about the power source. I really do not want the power source to ever run the bike. I simply want it to assist me climbing hills. I dont want to run out of oxygen (fuel) as is happening now. So this is my planned power set up, please tell me any flaws you see in it. One twelve volt battery 12ah complete with momentary on off switch. Push the button when I need a little assist climbing a slight grade. A completely secondary battery probably 7ah with its own momentary switch just to kick in on top of the first battery. When both are on, It should make a 24volt system for steeper inclines for just a few minutes at a time. What problems do you foresee. Any advice would be helpful. Did I mention I like to tinker with stuff. I found over the years when you buy something you learn to write a check. When you build something you learn lessons that are transferable to all problem solving. And my wife made sure I knew how to write a check early on.

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
