Thanks for the info Tony.

Any other component on the bike would let out the magic smoke if it pulled that much power. I suspect that to save on extra components in the controller the wattage displayed is just software showing what the controller is programmed to output rather than the actual current draw of the motor.

In most of the posts that I have read about sudden power loss on E-Bikes the whole bike shuts down so the owners of those bikes never get to see what I am seeing.

No the battery is easy to remove and during my diagnosis I did check the connector for damage of any kind but it's all fine.

Every once in a while my rad mini motor loses power. When applying throttle the motor weakly moves a short distance then stops. If I rotate the rear wheel backwards a little and re-apply throttle the motor does the same thing. On the 2 previous occurrences of this issue it fixed itself but the latest occurrence did not fix itself. After a few days of unsuccessful diagnosis I accidentally bumped the cables under the pedal crank and suddenly the motor started working again.

I inspected the cables and connectors but found no damage and all the connectors were fully seated. I wiggled the cables and connectors, I took the bike for a test ride but the bike worked perfectly again. I suspect that maybe the cable or the connector between the battery cradle and the controller has a problem but until I can recreate the problem I can't be sure of which cable is causing the problem.

What is strange is that when this happens there is no power loss to the rest of the bike. The Display remains on, the lights work, the brake light works when squeezing the brake handles and when applying throttle the display shows wattage being applied to the motor which in itself is kind of strange because the motor isn't running.

Has anyone seen these the same or similar symptoms and figured out what is causing this?
