Has anyone bought and installed one of those 2 cycle friction drive kits sold on eBay that come complete with engine?
motorized bicycle gas engine rear friction kit 49cc new - eBay (item 190458443260 end time Nov-18-10 07:45:37 PST)
It's kinda hard to see in some of the pictures, but it looks like the drive roller used in these kits is not a knurled drive roller, but rather some sort of elongated drive gear like those used to drive toothed belts?
I would think the friction provided by such a drive roller would be inferior to those that are supplied by
BMP, DAX, and Staton.
Anyone have any thoughts?
