Bamboo One won't engage for more than a second

WHen I turn on the Bamboo, then the (new type) remote, it won't spin the motor. It will 'click' briefly, but not spin. It will brake though if I'm moving.

I went back to the old remote, same problem.

I removed the wheel and belt and belt cover. No love.

I held down the left button on the remote so that the dark blue flashed on the top two buttons, and it spun for a few seconds, then stopped. Couldn't get that to happen again.

Last time this happened (with the new type remote) after a few tries it started to spin and I was able to ride it, and then again a few days later it started right up as normal.

 

Having a similar issue. I have an old remote and a new one.
The new one does this weird thing where if you use the brake, you have to reset the remote before you can go again.
If i switch back to the old remote it works perfectly. I'm still investingating...
