General  Information           First Few Rides go Slow!!!



Obey all traffic regulations.  Always wear a helmet while riding.  Remember that you are riding a motorized bicycle and other traffic may not be able to see you.  Never operate your motorized bicycle on a pedestrian through way or sidewalk while the engine is operating.  Never operate your motorized bicycle in an unsafe manner. Check local and state laws before riding on streets.   WARNING!  ALWAYS wear a helmet while riding. 






Motorized Bicycle Starting and Operating instructions:






1.  IMPORTANT:  PLEASE READ THIS:   Gas and Oil Mixture for Fuel ratio



The engine is a 2 cycle design, therefore, a gasoline/oil mixture is necessary. During the break-in period (1st 2 gallons of fuel), Break in ratio for 80cc is 8 oz. 2 Cycle Oil per Gallon. After the break-in period, 4 to 6 oz. per Gal. depending on use. Use of Pre-Mix or Synthetic Oil is not recommended!!!  I useWalmart Super Tech 2-Cycle @ $13.84 per Gallon.Before riding and on a periodic basis continually check Nuts and Bolts for tightness. Engine vibration can loosen. “LockTight” is recommended.




*NOTE: Use only 2 Stroke Oil to insure proper engine lubrication.  






2.  If the rpm needs adjusting, turn the idle adjust screw (left side of carburetor) in or out slowly to obtain the proper idle speed of about 1400 rpm +/- 100 rpm. To correctly break in the engine in do not exceed 15 mph or 30 min. continual running for the first 50 miles during engine break in.  Engine will develop more power after break in.
