Kids' bikes with polyurethane wheels
Polyurethane
— a wheel that combines a rigid material rim with a solid tyre made from polyurethane, a polymeric substance much like rubber. This design provides strength, resistance to damage and some degree of cushioning. At the same time, for a number of reasons, polyurethane tyres are found mainly in tricycles that are not designed for serious loads.| polyurethane | clear | Save List |
