Is this true and there any way around it? I don't want to go crazy speeds but 30km/h just feels better, especially given that a lot of roads around here are 20mph limits
This is probably true to ensure the manufacturers aren’t liable if the eBike is used at an illegal speed. The limit in the UK is still 25kmh or 15.5mph and after that you’re breaking the law if it’s used on the roads.
I’ve a GoCycle, and alas even though it’s 16.5kgs and only has 3 gears, I can easily pedal it faster than the software will legally allow the motor to kick in. I’d love it to go faster, but at the moment you’re touching dodgy ground if you have an accident or something bad happens.
