I have a Kalkhoff Agattu town ebike with hub gears, which I love. My wife has my previous bike, which is not an ebike. I find that at 15mph in the highest gear my legs are going as fast as they can but my wife is leaving me behind. I need advice on which sprockets to change to give me higher gearing, maybe up to 20-23mph.
Any replies appreciated.
