The Cowboy V1+ is a great bike. The looks are clean and the motor gives you a real boost.
Unfortunately I had some problems with the headlight. However the great support team solved this quickly by sending the spare parts and a mechanic to replace them.
Furthermore it can be tricky to mount third-party accessories. But if you are handy it's not that difficult.
For me the circular V1+ is well worth the money. A great bike for enthusiasts.
