Twist and Go 15.5mph DIY Ebikes are legal

For non-KT conversions: How difficult would it be to install a secondary pedal sensored system which keeps the throttle deactivated, so that the throttle can only activate motor power while the pedals are moving?

One moment, please...

Thank you, that's very interesting. I was thinking of a system working completely independently of the controller, to install on a BBS01B say: A small computer calculating speed using input from a secondary pedal sensor, and only allowing the throttle power while the pedals are turning, and while the speed is less than 25km/h. A small system which can be fitted to any ebike with an illegal throttle, for people who really want to retrofit a legal throttle which passes the police dumb roadside throttle test. Of course, cops could simply declare the pedelec illegal upon sight of a throttle regardless.

Pardon our interruption...

I didn't study it fully, but I'm pretty sure that it'll work externally. He's just using a a small micro controller to read the pedal sensor, speed sensor and throttle, the using logic to switch the throttle and brake input.

You could probably do it with a transistor to switch the throttle signal on with direct switching from a branch of the pedal sensor smoothed by a capacitor and resistor, and an inline resistor to reduce the current. isolate it from the main PAS signal with a diode.

Hi I'm a journalist looking at e-bike conversions. If you have experience with DIY conversions, faulty conversions and batteries, fires, or using a conversion as a food courier or delivery driver, please reply to this post of DM me. Thanks.

You need to post this somewhere more obvious, it's hidden at the end of a thread. Hope you aren't just chasing knocking copy though. What paper is it for?

He posted same thing in few threads and opened a new one.

that could be confusing, where to actually engage then? Perhaps he's from the Dully Fail or one of the others not concerned with truth, only sales.

I have a Fiido D3, if I restrict the throttle output to 3.7mph, will this then be classed as legal? it has a 250w motor a maximum speed of 15.5mph and is pedal assist.

Yes.
