Re: How much do Friction Drives Slip in dusty conditions??
heck if it is flat ... get a ryobi 31cc weedeater motor. use a standard bmx type axle peg for a drive and have at it. Darn thing will do 20 to 25mps unassisted on the flat. You will have to pedal on any incline but its good exercise.
I ride on pavement so I can't help you on the slip for dust. Water make it slip. Stay out of the rain but a puddle slips for only a couple of seconds. Thats all i know for sure,.
