The roller comes with a friction drive which helps transfer power from the engine to the rear wheel. The power is transferred from the 38 or a 49cc engine to the bike’s rear wheel. The drive rollers promise strength and hardness. The larger the drive roller, the better it is as it gives the bike a great speed. The installation of the friction roller is easy and quick, so you can get these replaced easily.
