Most geared hub motors have a freewheel built in, but finding one that would fit might be hard. The drag might be from the brakes or...

No, I wouldn't worry about that much increase. Most controllers can take quite a bit over the rated voltage.

What controller are you using?

Looks like it didn't work. Those contacts look pretty burnt.

I've done that before. Took a while to figure it out.

It could be either one. Most controllers will have several fault conditions that will disable the output. These include brake switches...

You can try measuring the voltages on the throttle wires when it's on. Measure against ground or battery negative. You should see 5v on...

Possibly the motor stator came loose from the axle.

One thing that comes to mind is there may be a significant voltage drop in the ground wire going to the throttle. You could try...

That's normal behavior for a BBS02. Going backward, the freewheel clutch allows the motor to spin, which will generate power. The...

Possibly the chain itself. I had one where a link got stuck and didn't pivot which caused it to jump sprockets. Make sure each link...

Right. You should be able to make a generic throttle work, but the wire colors most likely won't match and you'd have to figure out what...

Is the 3 pin connector the only one coming out of the motor? If so, it would appear the motor doesn’t have hall sensors. You can use a...

I wouldn't worry too much about it. Once you start running it, the battery voltage is going to drop and get below 14.5v fairly quickly...
