Hi, I am very new to this, but I recently picked up off the curb a simple push lawnmower, 3.5 HP. I would LOVE to put this on a bicycle of mine. The easier the better, but I have seen that since it is a vertical shaft, things become a little more difficult. I also have a stationary bike adapter thing (like the ones here: Stationary Indoor Bike Trainer - Kinetic by Kurt ) I can hook that up to the rear tire, and if I could somehow put power to it, it would be just like a friction motorized bike (I have been able to simply hook that stationary bike thing, and put a cordless drill to it, and rode around my driveway at about a walking pace, obviously too slow) Any suggestions oh how I could rig up this lawnmower engine? I know I am limited due to the shaft, but let me know!!! Thanks!
