What's a practical gear reduction ratio for a GX35 driving a 26" mountain bike?
With the power cranked down to 200W for local regulatory conditions, I'm limited to around 25km/h top speed.
I bought a kit with a 20:1 drive ratio, but it arrived with sprockets for 25:1 and I'm pretty sure that's not going to help.
It's just that 5000 RPM at 25km/h seems excessive to me, and I think I'd be happier drawing the 200W at 4200 RPM like the setup I paid for.
Any clues as to what I should be aiming at?
