Thanks a lot!
We don't really have the money to have one bike each. We swap every second weekend on who rides it.
Maybe if the economy goes back to something more stable then we can both have our own bike.
Is it worth unlocking the bike? A friend of mine can do it for a small price.
Yes, it is worth unlocking the bike. Do an internet search first on how to do it. Usually, it doesn't require anything special, just holding down a combination of buttons or entering a combination of buttons.
I think you're limited to 25 kph assisted there, which is 15.5 mph. Our slowest (Class 1) eBikes here limit assistance to 20 mph, which is 32 kph. Your range will suffer, but you will be able to keep up with traffic better. It's also more fun. I don't think police can give you a problem unless they borrow the bike themselves to confirm it assists past 25 kph.
By the way, we have a three class system here in the USA:
Class 1: Pedal assist only. Assistance limited to 20 mph. (32 kph)
Class 2: Pedal assist or throttle. Electric power limited to 20 mph. (32 kph)
Class 3: Pedal assist or throttle. Electric power under throttle is limited to 20 mph, electric assist under throttle is limited to 28 mph. (45 kph)
It's hard to enforce and our police generally have better things to do, so there are a lot of outlaw eBikes here. A common violation is a bike that will do 28-35 mph (45-56 kph) under throttle only. If someone was doing that on a multi-use path "bike trail" around pedestrians, they would probably be ticketed.
