The Tsunami Ultra from Waters Fitness is perhaps the future of spin bikes. The Ultra uses magnetic resistance. Not only does it use magnetic resistance but the resistance is indexed so that the user knows the exact level they are at while training. This indexed resistance gives more feedback to the user to maximize their workout.
Experience the “Ultra” best in Indoor Cycling. The Tsunami Ultra combines an indexed magnetic system with a drive belt to provide 20 levels of smooth, quiet and repeatable resistance. It is built on the same durable frame as the Tsunami Pro with large oval tubing and a low step-over height. Bike specific geometry and a flywheel safely built into the frame assure comfort and stability.
