Last week I bought a Sixthreezero "Around The Block" 500w electric bike and the shop sold it at a good price because they were lazy and didnt want to fix it themselves. It's barely used and has only 32 miles on the odometer.

I keep getting error 24 or error 21. And barely any power from the motor. The throttle responds but only for two seconds and it slightly engages the motor. Same with pedal assist. I can hear the motor whine but barely any power from the rear hub

When I first started looking at the bike one of the wires from the battery to the controller had a messed up bullet connection on the male end. I'm pretty sure it was the positive phase wire from the battery to the controller. I thought it would be a good idea to use a butt splice to just bypass the bullet connector for that wire. After I cut the bullet connectors off I did a butt splice with heat shrink and the bike is still showing error 24 or error 21

Also I noticed that there's a puncture in the wiring going to the throttle. It has three wires inside it and I haven't attempted to fix it yet because I'm not entirely sure how to reconnect them. I'm guessing solder them and use heat shrink.

Any advice is welcome, this is my first ebike and I'm just trying to get it working so I can use it to get to work
