DFT consultation on increase of 250W limit to 500W

[eas2lv]

What would it take to make a legalising retrofit kit for those with ebikes which currently have illegal throttles? A second PAS disc connected to a computer which limits/delimits and varies throttle votage signal between 0V-5V depending on whether the rider is pedalling or starting from a standstill, limiting throttle assist speed to 4mph when starting off, and allowing up to 15.5mph if pedalling is detected? The Oi Copper! ThrottleMeNot!™ is invented.

Apparently Swytch GO in the EU/UK version has something like this implemented in the controller firmware. The throttle works for start assist (speed < ~4mph) or if pedalling.
Quoting from Swytch site: "in accordance with EAPC (Electric Assisted Pedal Cycles) legal regulations in the UK, European Union and other regions with similar restrictions, the pedals must be in motion for the motor to provide assistance, so it will not work to full speed when you are not pedalling in the GO generation Swytch Kits."
