The Wisper full throttle ebikes make use of the 250W LPM moped legislation and what would be a realistic and allowed maximum controller current for such ebikes? Does it follow the same rules as the EU ebike certification in that a motor can be rated as 250W despite the controller feeding it up to 25A at 36V and still classed as a 250W ebike or does the 250W LPM legislation have a greater limit on power. I've not seen it discussed. Looking at the Wisper full throttle ebikes they all look fairly low power to me all with small hub motors currently.
As is shown on this site the Department for Transport allowed for ebike kits to have twist and go throttles and they didn't need to go through the type approval process but they still need to comply with the 250W LPM legislation rather than the EU ebike certification. So realistically how much power can such a kit have and still be legal? What would be a realistic maximum continuous current rating from the controller for 250W LPM?
I guess this is a question for Wisper in how far they can push wattage and still get type approval for their ebikes? Have they even tried to get a mid-drive or high power hub motor ebike through the type approval process?
