Hello folks. From another post regarding a bmx bike, an interesting picture came up of a 4-stroke motor rear mounted on what seems like a standard rear rack. The picture only shows the plastic face of the motor but it doesn't even seem if there is a complex transmission on the motor, but rather probably just a straight shaft to the rear wheel sprocket. I was always under the impression that you needed a properly built rear rack mount for a 4-stroke motor. Could you really simply mount a 4-stroke motor on a standard or premium rear rack? I mean if you could, I think this provides significant advantages over a frame mounted engine or a rear friction system:
- Eliminates the specific frame size restrictions of a 4-stroke
- Lowers costs (just need engine with straight shaft and sprocket, chain, gas tank, and other minor things)
- Provides a super easy install (put on rear rack, put on motor, put on chain, and hook up lines)
I only used 2-stroke engine so I have no idea of the mount requirements for a 4 stroke. And, lol, I also been posting way too much...
