Great job, and a really interesting conversion. How much noise is there at 20K RPM and how many amps?

hodala

Just received the controller then test run, the noise of fan in the motor sounds strong with full throttle,when riding- -the wind through your ears should much louder then the motor, bevel gears should get well lubricated to reduce noise rather

Final sprocket and disk caliper works OK !

For now

Test run, need to improve in details

I'm going to add 2 spare wheels - 3+2 wheels / 5x3 all terrain cargo bike
each spare wheel propelled by a 895 motor

The spare wheel rpm is lower(10km/hr), when you ride in rough terrain or beach, put down 2 wheels to increase more power and tractions
