sabongi - That part is a freewheel and acts as a pinion. Making it bigger would make the gearing even worse.
The gear reductions are - 11/72 to the "spool", 14/32 to the crank, and 48/12 to the wheel in top gear. I want to get about 35 in top gear. The motor is 250kv at the moment and I'm running 24v. That's 6000rpm. The wheel has a 13" radius so 2pi13=81.7 inches/revolution.
I'm not quite sure on my math, but I think I get 1,584 rpm at the wheel so that's... holy sh!t - 180mph!!  - Someone check my math...
I figure I will need 1,168rpm at the motor so thats... 49kv. 
Is this going to work out or will I need to make some major changes to the gearing?  |
I think your best bet would be to get a 3s lipo
IDK if a flux capacitor will fit on a bike though
