our controllers are nearly all speed based, meaning even an innocent little 1mm of throttle is enough to demand say 6kph (sounds fine, till you realise the controller will give you absolute full tilt until this speed is reached, then nothing once you are there) thus we come off the back from this 100% torque responce to our request for say 3-20% that we asked for/expected.
we need torque based throttle here, not speed, as its torque/or force that flips you. torque is what we feel and naturally need to be in control of and this is allready the case for car/bike gas motors that we are used to, and comfortable with.
seems straight forward enough, but unfortunatly in around 99% of cases, the human brain is not capable of accepting any of this, even once explained (in writing here or in person after they got flipped by a geared bike), so little progress can be made till people get there heads around it, more and more folks are asking about it now though, so give it few more years.. :wink:
-ps thankfully justin is onto this now with the new v3 cycle analist in beta testing with torque throttle conversion and programmable throttle curves, this could well be the answer cos even a 20kw+ beast will be nicely tamed for a slow wander up some stairs, but with full torque on tap (but only when YOU ask for it)
