Weird problem
Hi! This is my first post and it's about a strange problem I'm having with my e-bike. I have a 1000w 48v homemade Aliexpress type bike based on a cheap but new mountainbike. It's a direct drive hubmotor in frontwheel. It came with a squarewave controller that made the motor noisy and squeezed out ~1200w. I then bought a sinewave controller that leaves 40 amps (~1800w) and made the bike totally silent, BUT, it now have a strange thing that it makes. When giving full throttle it accelerates like...hell. If I then lowers it tho say half throttle and it's downhill, the motor "brakes" If I keep going like this for awhile it turns off. The regen is turned off. I have changed settings in the kt-3 lcd display to different settings, but it does this. I don't think it did this in the begining. Is the controller faulty? The motor? Is there someone who has experieced the same?

The C13 parameter sets regen strength, but there may be a hardware switch to enable it. On mine, there is an EABS jumper. It's a pair of grey wires on my controller with a 2 pin connector. Comes with a two pin plug to complete the circuit, which enables automatic regen. If you have this circuit on your controller, and it is plugged in, unplug it and see what happens.
My geared motors can't do regen anyway, but I cut the grey wires off to clean up clutter. Also removed the wires for lights (they call it lamp/speaker), cruise control, and speed limiter.
