I've just finished a custom ebike build with the objective of having very long range.
The motor is a 250w rear hub geared motor (no brand) laced into a 20" wheel and the controller is rated for 350w. The controller only has a throttle input (no PAS)
My battery is a 48v 50ah lifepo4 and is frame mounted
I've finally wired it all up and took it for a test ride but if I push the throttle gradually the motor starts turning for just a second before immediately making a very loud grinding/screeching sound and will continue like that at a very very slow speed with this loud noise (won't go any faster) until I let go of the throttle. If however I push the throttle full, the motor accelerates very quickly and seems to get past that 'cogging' stage and shoots of with consisderable speed.
I am not sure if it is a motor, controller or throttle problem.
The sound is similar to screeching bike brakes but much louder
The bike has a drop stand so I can prop the bike up and test the motor and the problem does not appear at all. I am wondering if the motor can't handle my weight (76kg)
I was also wondering does the 350w controller only draw maximum 350w from the 2400w battery so it is ok to use a battery of that capacity?
