Our Training Wheels Trainer system allows for adjustability and adaptability. With our Trainer you can adjust the wheel height and mounting position for your type of riding terrain as well as rider’s skill level. As the rider gets better raise the wheels incrementally higher until balance is achieved. Start with training wheels fully down and as your riders skills and confidence increase raise the training wheels incrementally until they are fully up. Installation is easy because our Trainer is specifically designed to fit the Razor 350 or 400 model. Inclusive directions and video walk-you through assembly. Our Trainer mounts under the motorcycles swing-arm for the best balance, strength and durability. We use CNC machined bracket mounts for perfect fit every time. No “stamped” or “punched” material that falls out of specification and ends up not fitting your bike. The Universal Trainer will give children quality “seat time” to develop important riding skills while offering parents complete confidence and satisfaction. The greatest attribute of the Razor Trainer is that it is adjustable. As your first time rider gets better you can adjust the height of the wheels to slowly help your rider achieve balance.
