Old Giant struggles with hill.

[jarnold]

It doesn't seem like a long/steep/high enough hill to trigger low voltage cutoff or thermal cutoff, no brake switches to go wrong, cadence sensor working fine, I can't see an answer from afar!

I know, weird? It's probably just user error. I'll get out there again, stay in low gear and make sure I pedal constantly to the top. The problem is that cars keep driving up and down and I don't have the confidence I had 5 or 10 years ago. And the potholes...

How fast is the bike moving at cut out.

Once again, I don't really know, there's too much going on at once.

Alternatively, I could jury rig a throttle, just for experimental purposes, but that's not my aim.

I would also be interested in the "no load" speed (with the motor wheel lifted off the ground). I suspect this might be too high for strong hill climbing although the controller shunt mod will definitely help

Hard to say, without moving the spoke magnet sensor to the front(driven) wheel.
