I can now legally throttle uphill with the new settings, very slowly. I don't know if the amperage setting for my Level 0 is being ignored, doesn't feel like 18A, but the throttle is certainly limited to 6kph max. Throttle may be using the amperage specified for Level 0, or some other variable in the firmware inaccessible to Speeed App and Penoff's configurators.
I tried some hill starts - throttle helped, if you activate pedal assist at the same time, so that the moment you let go of the throttle, pedal assist kicks in immediately and launchs you upward. Timing takes a little getting used to, ie when to let go of the throttle. I quite like "Start Degree" set to 2, helps with throttle assisted pedalling starts. Normal starts on flat road on highest gear are also easier.
I also tried throttle assist uphill starts on my highest gear, and heard nasty plasticy grinding inside the motor (at least I think that's what it was), I reckon it was probably too much for the nylon gears. Unsure. This also happened on my highest gear starting exclusively with throttle on flat ground. Best avoided, I think. I'll try dialing Start Current for throttle down to 10%.
Hill starts without pedalling is very slow using throttle exclusively, it's not easy to balance going that slow, possible on low and medium gears. Using 18A pedal assist, climbing those same hills is dead easy on my highest gears.
If you start exclusively with throttle and no pedalling, there's a shortish delay between the end of throttle and the beginning of pedal assist.
On level ground it's dead easy to dawdle along throttling dead slow, provided you can maintain balance.
Having replaced firmware of zillions of other devices over the years, I've learned to be cautious - until I know for certain an open source firmware replacement is compatible with the BBS01B, I won't be flashing my controller. I'm sure all manner of things will be possible once I have access to code. But for now, I have a legal 6kph throttle on my BBS01B (
see post #54). I was quite happy without a throttle.
