I was asked to look at a rather old (circa1998 I think) step-through front hub drive bike today.

I pulled the rather unusual battery pack out and discovered it had about 41v at the terminals off-load. The owner who has intermittent but severe dementia said it wouldn't charge and needed a new battery. I pulled it apart and found the locking key/power switch had failed. I shorted out the switch and the 3 lights on the twist throttle body lit up. Twisting the throttle did nothing. has anyone any ideas on this? I traced the cabling back to the controller and all looks ok, same with the connections to the motor. The controller is a bit of a mystery box, no labels or numbers on it at all.

For the original Powerbykes, you have to pedal it initially to enable the throttle, but once going, you can use the throttle without pedalling. Maybe that one is the same.

After putting the bike away in the garage last night that thought did occur to me, that having to pedal first to start the motor was a possibility, I tried it today. Thank you @saneagle and @flash for the confirmation. Just tested it and it works.

Happy days. The last few days has to be a record for confirmed solutions. We're on a roll. I'm now so full of optimism that I'm off to vote to solve another problem. Goodbye Agenda 2030.
