saw a good deal on a lifan motor 150cc and wanted to know if anyone had tried to put that big a motor on a bicycle? im sure it can be done and if bidding goes well Ill have the motor in about 3 weeks.....im just worried about how fast im going to kill myself on the thing once i get it installed.....but best not to count the chickens before they hatch i suppose. still got to obtain the motor.....may have to build a custom frame for it......i picture something like that happening and then this or this
