Got the 320 in the 700c wheel last night. Here are my initial impressons:
While the 210 motor goes slower than I normally pedal, The 320rpm motor feels like a different beast. The slow motor is lazy and relaxed, like riding a 2 wheeled golf cart. The 320 motor is a speed demon. It likes to go 25mph where the slow motor likes to go 16mph. Big difference. I think for many people something in the middle would be nice, but Cute doesn't offer that. I did see a little Bafang on GreenBikeKit that was 260rpm. That might be nice for some people.
While my initial impression is that the 320 motor fits very nice on a 700c wheel, with the important caveats:
- Only use the motor above 15mph
- no sustained hills
- rider willing to help out with the pedaling to sustain 20-25mph pace
The 320rpm has a no load speed of 30mph (just like http://www.ebikes.ca/simulator/
says), probably would do 20mph by itself, but responds very well to user input to add 5mph or more.
I need some more seat time, but the 320 motor looks to be a nice solution for a fast rider who is willing to do some good pedaling.
Attached thumbnail shows the 201 motor riding at 15-18mph (this morning's commute), and the 320 motor (road bike) riding at 25mph (both with pedal assist):
