Indoor Cycles that are designed for use in a commercial environment need to be tough and hardwearing. Group Cycling classes are a great way to keep fit and, for anyone who's been to such a class will know, the bikes can take a real beating. Therefore, the frame, bearings and cranks need to be very strong and designed for many hours use each and every day. The BH Fitness range of full commercial bikes have been installed in gyms across the world and are proven to be long lasting, high quality fitness bikes.
