After visiting Decathalon and a few local bike stores (only one had a good stock of new and used bikes, others mostly focused on maintenance and repairs), we had an amazing experience at @Zweirad_Stadler, Charlottenburg. #Berlin
Stadler is a really big warehouse’ish store, just outside the S-Bahn ring; unlike Decathalon, it is a two-wheeler-only store for new bikes. It has a huge selection of different kinds of bicycles (city, trekking, mountain bikes, folding bikes) and related accessories.
What we liked the most is that they have an indoor bike test track, where you can really get a good feel of the bike and test its features.
