Short guide how to choose bicycle trailers. All bike trailer can be used as a spare for your bike in case of punctures or damage, and in a collision the trailer will safely disconnect from the bike. A trailer wheel with less load on it will easily reach a service point, but you can also replace parts on-site using Extrawheel-patented inventions. Each trailer model has a load capacity of 35 kg, and the load can be easily mounted to the bike using a revolutionary fork. The unique fork design allows it to work as a shock absorber that dampens vibrations. Both the fork and trailer are unique solutions! Extrawheel trailers fit most bicycles from Urban, Trekking, Recumbents, Road bikes, MTBs, and Tandems to e-Bikes, thanks to the adapters that we offer!
