My new Cowboy bike is great! The overall quality is very good and I am happy about it.
The installation was very easy and the bike was ready in 15 minutes after it was delivered.
The motor works perfectly smooth and is there when you need it. The range of 70km is very close to reality.
The App is easy to understand and is a perfect extension to the bike.
The only minus I figured out so far is that the brakes started to squeak a bit. I'm Sur that I'll find out how to fix it.
