I think you did a great job designing and implementing this. However if you are in Germany unfortunately electric bikes and other personal electric vehicles with a top speed over 15 km/h (off the top of my head) need to be registered with the traffic authority and carry a license plate. It’s basically impossible to do this for DIY builds, as far as I know.

I have a home-brewed eBike here in Sydney, where the rules limit you to 200W (or 250W if it's pure pedal assist without a throttle).

Mine will pull almost 750W going uphill on a freshly charged battery.

It has a very prominent "200W" label on the outside of the battery holder.

If I rode it like an asshole, doing 45kmh on sidewalks, I doubt my "200W" label would do me any good. But I've had it eyeballed by police when they're doing their semi-regular "fine everybody without a helmet or a working bell" crackdowns on CBD commuters and have stopped me to check my bell works, and never had the power questioned.

I live in Germany myself. I mostly built this bike for fun.

I think it's 25 km/h + tolerance = 27.5 km/h.

For electric bikes, that also require the user to pedal to get propulsion, the limit is 25km/h.

Note that this applies on public roads/bikepaths only. You're free to ride on private property as fast as you want (and anything you want, with or without licenses).
