As these drives are typically hill assists rather then full time assist, the switch is only being used for a short period of time. I have used a simple button setup before and actually found it quite compfortable as you arn't chasing a postion to hold it in. Also looking at using a pressure sensitive strip rather then a button.
Lots of options to test. PAS is already to go also to meet our stupid Australian requirements in the near future.
2 Seconds may prove to be too long for de activation. This off cause will be optimized during testing.
Should have the code by the end of the week so looking forward to some more testing.
I don't know much about this, but it seems to me that a suitable pedal sensor could replace brake switches, even with a hub motor. After all, the very first thing you do in an emergency stop, even before you hit the brakes, is to stop pedalling. Try it.
It would also prevent the uninitiated applying full power when the bike is not moving. In fact, you could have a power selector switch that stayed on with having to be held in, so you need not have any extra controls on the bars at all.
