The gears don't seem to wear any faster or get any noisier from this bi-directional torque situation since the opposite tooth faces are involved.

On 72V with 26" MTB wheels it reaches about 28-30 mph using an FOC PhaseRunner with no field weakening (on this motor).

2012年4月2日 · in hot/shine weather in Phoenix. I replaced parts of the bike (controller, battery, a set of chain, pedals, flat tires) but the motor kept going. On the other hand, my 600W BMC geared motor only lasted 6000 miles before the gear clutch started to malfunction. So now I am riding a Crystalyte HS direct drive, sensorless and still going after 5000 ...

Primary use will be commuting to work, 13 miles each way with a few moderate hills. My plan is to pedal most of the time along with use of the motor. I like the lower ...
