Beautiful! I've been dreaming up something similar, but with a 4-stroke engine with centrifugal clutch and a 3-speed hub.
Thanks Ollie.
If you want to go full suspension motorcycle tough and use a 4-stroke the MotoPed frame is heavy on the beef.
It is a direct drive jackshaft to a single speed wheel as well but different, the freewheel doesn't carry motor force, it's just for the pedals to spin.
And it is designed for a big 4-stroke kick start semi-automatic motorcycle engine.
I went with this:
Single cylinder, 4-stroke, 2 valves

Ignition: CDI, 12 volt, permanent magnetic stator
Maximum Power: 6 hp@ 7,500 rpm
Maximum Torque: 4.25@ 5,500 rpm
Gears: 4-speed, semi-auto, 4 DOWN.
Idle: 1,500 RPM
Final Drive: 14 tooth #420 front sprocket included (we have other sprockets on sale too!!)
Lubrication: 0.8 liters, 10W/30 4-stroke motorcycle oil, pressure and splash

Buyer will receive 88CC Motor, 22MM Carburetor, Intake manifold, intake gaskets, Shifter, Kick Starter, Wiring Harness, CDI, Spark Plug and Ignition Coil.

$289.95 delivered and I just got it mounted in last week.
It's supposed to come out looking somewhat like this.
Hopefully I can get this done before the Surley customer comes to get his for a 2 bike 'dirt bikes' shot like my 2- bike 'Fat Tire' shots.
Did I mention I am having fun building all this cool stuff?
