The bike is nice and rides quite well. But I have a few reservations - it would be great to be able to turn on engine assistance even above 25 km / h. I'm also having trouble unlocking the bike. Even though I'm standing by him, in 100% of cases I have to disconnect, forget and pair the bike again on the iPhone in the Bluetooth settings. I use the current version of the application on my phone, but there are still problems with it. It's pretty annoying.
