Its super-smooth magnetic resistance unit features a heavy 6.25-pound flywheel simulating outdoor riding, so that you experience the same feeling and workout you get outside. And, with its handlebar-mounted thumb lever, you can choose from nine levels of resistance for everything from easy spins to hard efforts to full-on intervals and sprints. The Kinetic Magnetic trainer is the perfect choice for bicycles with lower gearing, like cyclocross bikes, fixies, singlespeeds, mountain bikes and even BMX bikes.Other great features include the super-stable oversize steel frame that folds for easy portability and storage; a secure, easy-to-use quick-release bike mount so you can go from trainer to outdoors in a blink; a 2 1/8-inch-wide roller that minimizes tire wear; and the ability to use bikes with both quick-release and bolt-on rear wheels.
