80 cc gas powered mountain bike kit

I was intrigued by the concept of a light gas powered bicycle for getting up logging roads for hiking and skiing. There are many kits available. There is sufficient power with 68 cc and the correct gearing. The standard 44 touth rear sprocket is for highway use, I ordered the optional 50 tooth sprocket with is adequate for grades below 18%. I recomment front suspention especally for coming down. Most logging roads give the bike and rider a real workout. Some kits claim to be 80 cc but are in reality 68 cc.

really? it cant go up? does it stall or tires dont get enough grip? and how powerfull or they i have one but its not quit finished fueline problems

Kyle the bike is perfect on smooth roads up to a certain grade. With the 50 tooth sproket max speed tops out at around 15 KMH. On steeper rougher roads an ideal speed would be around 5 KMH, the problem is the RPMs at that speed are too low and therefore not enough power is developed. I have had lots of fun and I am sure you will also.

I rode mine to work a few months ago, and was going to keep doing it untill I was informed that the thing was not legal to operate on the road. Floridas laws suck. you fing somthing to beat the high price of gas and the government smacks you down for it
