★★★★★
A great shop with a thoroughly professional yet human approach. I have been ordering from them for a long time and there has never been any problem. Communication works perfectly and you know where you stand right from the start.

I now have my second Haro bike from Katmar Bike Center – this time an e-bike. Completely satisfied. Professional and helpful approach. I warmly recommend this shop.

Reliable. I bought a new chain, it turned out to be unsuitable, but exchanging it for another one was no problem.
