Default Re: will a 33cc friction drive chew my tire???

If the roller isn't pressing down on the tire enough, it will slip and certainly will wear a tire quickly.
My setup is homemade. Springs pull the roller down; I started with a skateboard wheel roller and not enough spring tension. It was hard to tell that the roller was slipping, but it was and it wore down a tire in no time. Once I got the tension right, the tires last pretty long. Now I'm using a hard rubber roller made from a hockey puck. The statons have a steel roller, I think. If you gas it from a dead stop, it still should not slip, just bog the motor until you get up some speed. It's always a good idea to pedal a bit to get her going. Why wouldn't you? There's a price for being lazy (like my big gut).
