Ahh. didn't recognize you have e assist on your Villager. In that case, a 52t is basically the right middle gear if you use e assist all the time. Anything lower and you will not get any resistance at all when pedaling, you either ride like a moped with a throttle or "fake pedal" just to keep the motor running on pedal assist; you'd have to spin way faster than 100rpm to keep up. I'm looking to go to a 68t large crank ring to complement my 11-32 cassette. I'll either do that with a planetary system or swap out the chain rings and install a new longer chain. The other option, though, if you don't care about acquiring top speed, is to go into your display and into settings and reduce the amount of assist.
