Re: Help me develop the perfect throttle

Does anyone know how many Nmm the feather of a throttle should have? I will experiment a bit anyway but would be interesting to know.

Re: Definitive Tests on the Heating and Cooling of Hub Motors

Sorry for kidnapping the post, but does anyone remember where you could get these 3D printed files from?

How long should the throttle be? I mean the area you put your hand on. 120mm? 130mm? Tell me a number please :)

With a counter rotate option, the stop is gone, and the spring(s?) have to just balance at 0 or something, so (seems to me) it's harder to get a good positive feel near 0.
I already have an idea for that in my mind to have a good feeling on that.

Strong detent at zero power
Not a great Idea, the breakaway moment could be too high. Bad for slow accelleration. Maybe a click sound would be a better sound instead.

Re: Help me develop the perfect throttle

A switch in the initial twist region to switch off the stupid Bafang PAS. For those who don't know, the new Bafang mid drives get confused if you pedal with PAS and use the throttle at the same time. A simple normally closed switch could be set up to disable the PAS as soon as a git of throttle is ...

Re: Domino Throttle

Domino is inexpensive for what you get, which is the highest quality ebike throttle commonly available. But that doesn't mean it's the best possible quality. Yeah a high end, ball bearing (or whatever) throttle would be cool. I would buy one if it was higher quality than domino. I think a good pric...

Re: Help me develop the perfect throttle

Thanks for all your feedback till now. Im on it.

PS: I have tried both: Half-grip and full-wrist. I like full-wrist more as you don´t need to loosen your fingers on the stabile part of the throttle to turn it around.

Re: Help me develop the perfect throttle

Throttles should be silky smooth. It will be silky smooth, trust me. For the resistance of it I need to know your wished spring momentum in newton meters, maybe you have one in your mind? The Domino has between 0.07 - 0.09 newton meter. Do you want it to be lighter or heavier? My concern is in case...

Re: Help me develop the perfect throttle

Make sure it's possible to control the strength of the click, or disable completely. Otherwise there are going to be occasions where it's impossible to attain the speed you're after. E.G. when riding with somebody else, when following slower traffic, etc. No idea about that, my conception is, lets ...

Re: Help me develop the perfect throttle

Primarily that's because most ebike systems use a speed (PWM) throttle, not a current (torque) throttle, which is more or less what you get on an ICE. So the response is very different, especially as you get into higher power bikes. Could be. Sure a lot smoother up front, I mean heaven help me if I...

Thanks, but all they are doing is installing a variabel range for the throttle which is already possible via Kelly Controler and much more + the linearity of its response

Help me develop the perfect throttle

My current job right now from my boss is to develop the perfect eBike throttle (120mm wide, full wrist). Do you have any small or big wishes you always wanted to have in a 5V eBike throttle? Like a super-smooth spring-momentum or something similar?

Cheers, Elias
