Regenerative braking for bicycle

[iamthegelo]

Hi,

I was wondering about the idea of having torsion springs as a means to store kinetic energy when braking in a bike. I've thought about using compressed air but I am having troubles designing a gear system for both so that you can get the energy back to accelerate from rest.

Can anyone give me some inputs? Me and my group are stuck.

Thanks

Such a system would add weight. Would not the extra weight negate any benefit of the regenerative system. Also what kind of bike. engine powered or pedal powered. If its pedal powered I have no troble accelerating my pedal bikes. Thats what gearing is for.

I know people should be encouraged to think about new ideas, but I can't resist posting this...

Use a flywheel with a rubber cone attached to it. Mount the assembly on a track that will keep the surface of the cone in contact with one of the tires. Design a mechanism that will allow you to disengage the system when stopped and re-engage when you want to use the stored KE.

The added weight becomes transparent once the vehicle is up to speed the first time.
