The Roll Up offers similar performance to our Generator Wheels, but weighs and costs less, and doesn’t require you to change out your rear wheel. It uses the same power generating elements found in our Generator Wheels but in an external roller, not inside the hub. It boasts a very large roller with a gritty composite surface that simulates riding on the road better than small rollers found in competing products, which waste energy as heat and cause more tire wear. The large contact patch formed between the 6” roller and your tire means less force is required (roller pressure). You won’t see any deformation of the tire. More of your good clean Pedal Power goes into the device you’re powering. Plus, the large roller functions as a flywheel to smooth out your pedal stroke and make pedal power feel pleasant. And it’s quiet!
