Re: Fat Bike/ Friction set up / Ideas?
Friction drive is definitely the easiest way to motorize a bike with 4 inch tires. Look for a kit that allows you to easily lift the drive roller off the tire for easier pedalling in case you have to ride the sidewalk or run out of fuel.
Members have been happy with ThatsDax and Staton-Inc kits, but you would need to contact them to be sure they will fit the 4" tire. The ThatsDax kit appears that it would fit from the pics on the site.
