Hi,
I currently have a Cannondale F6 bike with a 1000W DD hub motor, a 6-speed freewheel, and a 42-32-22 chainset in the front.
My problem is that this gearing works fine until around 30-32 km/h, but once past that i need to pedal at an excessive speed to help the motor, and for the most part i end up just ghost-pedaling past this speed.
What i wish is to be able to still pedal at a normal speed up to at least 40 km/h, but i'm not sure how i would be able to do this.
The bike originally came with an 8-speed, but it looks like i'm stuck with no less then 14t in the rear now with the hub motor, so that leaved me with only the front. With the 42-32-22 that i have now, i always just leave the rear on the 14t, and mainly just use the 42t in front. While i occasionally use the 32t for steep hills, i've never ever even used the 22-gearing, and simply won't miss it.
So then my question is, what options do i have when it comes to replacing the chainset, how large will i need to go to pedal normally at 40 km/h, and how do i know how large of a gear i can actually fit on the bike without hitting the frame?
