actually those 2WD bikes had been indeed sold.I remember seeing a two wheel drive mtb in the 90s in some american mag. If memory serves, it had some kind of cable running to the front wheel to provide the drive. I don't expect to ever see one in real life.
Really like the look of that. Would love to own one
Bikes that you know must exist, but have never seen in real life or even on here
I’ll go first
1988 Fisher Procalibre
Very Nice ! Has to be a pro thoughI'm not sure if this is exactly what you're looking for Ant.. it's a Supercalibre rather than a Procalibre
