I bought one of these today... youtu.be/RNtHBEdZDYsMounted on a '70s Sears bicycle. No spark. Adjusted the points. Spark. No go. Squirted a bit of carb cleaner in it. Ran, sputtered out, no compression. Crank turns but the piston isn't moving. Haven't torn it apart yet. I'm hoping the Bottom of the piston came apart and my crank/conrod are fine. Either way, a parts hint will be underway. |

I built one a couple of years ago. 80cc with custom engine mounts on a flat black cruiser with red wheels. My wife said it was the coolest thing she'd seen.I sold it because it wasn't really legal or illegal here in Denver but it was really loud and stood out.

I'm really hoping I can fix whatever broke inside. I'll have one of the only American made two strokes in any of the forums I frequent.

I wonder if you could do any FWD bicycle burnouts on it..

Either way, a parts hint will be underway. "Up to a safe 18 miles per hour." I think if the piston has gone it could be a good for a BBK  Would be something nice to get working again |

I considered mounting one of those or one of the many variants on a recumbent Tadpole bike at one time. As far as burnouts are concerned, the drive on that one is trough a friction wheel against the tire. The 'smoke' would probably come from the friction wheel just before it chewed through to your tube... There are other kits available with chain or belt drives, even electric wheel hub motors. I was looking at using a Gates carbon drive belt system on a custom tadpole frame with a Shimano rear hub. www.gatescarbondrive.com/No noise, no grease, just smooth power... bike.shimano.com/content/sac-bike/en/home/components11/city---comfort/alfine1/sg-s700-s.htmlEleven speeds... A sprag or one-way clutch would be required. With diabetes I run out of steam or my legs cramp up at times which would leave me stranded on a bike. A motor would help with that problem. I bought a scoot instead. The 50cc engine and CVT is just not good enough. |

Having built and driven the gas powered bike, and I commute daily on a crank drive Bafang BBS02 with 960 watts of power going through an 8 speed rear cluster and I own a People 50 scooter, I can offer my observations.
The gas powered bike requires almost daily maintenance and without a variator, you pick between speed or hill climbing gearing. It is fun, but no more fun than a 50 cc scooter.
The electric bike is a great commuter if you have bike trails around you or have lots of bike lanes. I ride on 9 miles of bike trails on a 12 mile commute. I can get to work as fast on the electric bike as I can in my car or scooter because of traffic.
Having said that, I almost quit bike commuting because I have close calls with cars at least weekly in downtown. On the scooter, I have a close call maybe once a month and I have a helmet on and some power to help get out of the way.
The electric bike and scooter are much better alternatives then the gas powered bike, but the gas powered bike if done right had a great "cool" factor.

Oh, and if the gas powered bike craps out on you, and they do often, they are extremely hard to pedal as a regular bike. Of course if your scooter craps out, you have to push it.

Hmmm, I have seen gas powered friction drive setups with a friction release lever. That should cure the hard pedaling. A sprag clutch would also fix that problem. Unfortunately the one-way sprag clutch will eliminate engine braking. Damn scoots seem to need maintenance every day also... There is a cool factor with engine driven setups familiar to many of us; Noise and 2T smoke  |
