Default Re: Mongoose XR-75 MTB Weed Eater Friction Drive

Today I decided to see what kind of speed I am getting with the 1.25" bike peg, so downloaded a GPS app on my Blackberry to get speed and went for a ride.

On a slight uphill grade I was getting 17-19 MPH, and on a short flat I got up to 24 MPH! I probably could have squeezed out 26 if I had tucked down and had a longer stretch of straight road. This is with my 191 lb self (down from 205 a week and a half ago, woot).

I am very pleased with those numbers from a 30cc weed eater motor and a bike peg! On Cannonball2's recomendation, I strengthened the pull on my springs to increase downforce on the motor, and it got rid of my slipping problems without having to coat the roller. Thanks CB2!
