I've often written that it's trivial to inadvertently power-wheelie a short-wheelbase, upright ebike. The resulting loss of steering input and progressive decrease in counter torque (making it easier to loop) is dangerous.
Most controllers already provision for throttle cut via a normally-open e-brake switch that closes upon mechanical brake application.
Has anyone considered or implemented wheelie control via the e-brake circuit?
This could be implemented via a normally-open switch in parallel with the e-brake switch:
-a mercury tilt switch that closes upon the front end rising past an adjustable angle. This would be simple to implement, but imprecise and prone to acceleration/shock-induced activation. This would provide only gross wheelie control.
-a switch that closes upon full extension (topping out) of the front suspension. This would provide true stability control by ensuring the front tire maintains contact. Could be implemented with a pull switch mounted to the fork crown and connected to the bridge.
Thoughts?
