You do not have to be an adult to race with Socal Motor Bicycle Racing.Thank you. Anywhere I can read more about the event? Do you have to be an adult to race? I'm 16.
Correct, that is the problem with trying to shift with a handlebar lever.The top lever will shift up and the lower lever will downshift.
Shouldn't be to hard to rig up with just brake cable.
Switching steen levers isn't as hard as I thought it would be.
The only possible problem I see is not having enough travel or pulling power with the cables.
Heheh, ya, I grew up with Rat Rod posters and toys.yep...its starting to sound like a suicide shifter is my only option. Those comics are nuts!
Sounds Like an idea for gen 2. Hopefully after i finish this build I'll start another with similar design with a bunch of improvements.Heheh, ya, I grew up with Rat Rod posters and toys.
It is not your only option, you can fashion an electric solenoid system to move the shifter but far from cheap.
Well, I suggest you look at how MotoPed builds their drive trains.I went for a test run today (If you can call it that) and immediately stripped the fixed gear side of my hub
Maybe a 29er hub with a sprocket hub adapter? Would this work? I don't think the aluminum hub threads can hold up to the torque of the engine.
Any disc brake hub w/your main drive sprocket drilled & bolted to the rotor mounts outa work;I went for a test run today (If you can call it that) and immediately stripped the fixed gear side of my hub, this is the side the engine drives. My drive sprocket on the wheel uses the threads from a fixed drive sprocket. The locking ring that goes on after the sprocket completely stripped the hub threads. I'm not sure what to do now. Maybe a 29er hub with a sprocket hub adapter? Would this work? I don't think the aluminum hub threads can hold up to the tourqe of the engine.
I think you're forgetting it's a 49cc four stroker in a road bike;...The whole frame for that matter if you want to play with big engines.
...one I'm quite familiar with in fact but yes, they provide solid axle disc brake hubs as well, if you're so inclined - point being the rotor mount utilized as a sprocket mount, an inexpensive, clean & simple solution...It's got a four stroke Honda 50cc 3 speed engine out of a crf50.
Yes it is a 3 speed auto clutch. Although it is a 4 stroke 49cc these little engines have a surprising amount of torque first gear, enough to do a standing burnout.I think you're forgetting it's a 49cc four stroker in a road bike;

cooperDG123 - I would presume your CRF50 3sp is autoclutched, yes?
