I am extremely delighted with the bike... I use it to commute a distance of about 15 km (one way). It feels a bit like having super strength, especially when riding uphill.
The contact to the cowboy team and the support are great! The only downer so far was a spontaneous drop in the battery level (25%) - this only happened during the first charging cycle and was answered immediately by the support team.
I'm very happy with the bike, I can only warmly recommend it! The option on mudguards and a stand would be a good addition.
Keep it up!
