Waters Fitness Indoor Cycles Waters built a strong bike that can withstand heavy-use several times a day. The tubing is robust to withstand the daily pounding, the bottom bracket shell is oversized to increase bearing life, the resistance system is hooded to protect it from sweat. On the user friendly side, the handlebar and seat assembly have a Quick Release adjustment system to insure quick and easy adjustments, the frame has a low step over height while the heavy 50 pound flywheel weight gives you a smooth ride. It all adds up to the best value on the market.
