I
purchased the engine kit off
eBay for $150.00 for this bike and so far do
not regret it. Haven't had it long enough to know the mpg but know the
motorbike will save me gas money. The gas tank capacity is about one half
gallon.
A couple of years ago the bike was given to me by a friend . I replaced the bike chain and the same day I posted this information a new tire and tube was in order. I purchased a heavy duty tire and tube with the green gunk inside the tube. The engine is 80cc, 2hp, 2cycle. It runs very well and easy to start using a manual hand operated clutch.
The kit contains everything needed to install on a bike. Took me between 5 and 6 hours to complete the set up and could have been sooner with good instructions. Might as well not had any, all the good they did.
Only thing that bothers me is, if I need to replace a worn-out part I'm out of luck.
I've had this motorbike three months now, with about 400 miles of mostly trouble free fun. The only problem I have had was about my first 40 miles the drive chain idler pulley wore loose at the so called bearing. That allowed the chain to become loose and the chain jumped off the rear sprocket. I had to peddle the bike about 1-1/2 miles to get home. The idler pulley is nylon and without a bearing where the bolt goes though to connect the pulley to a bike mount.
Solution? I purchased a bronze oil impregnated bushing 5/8' OD X 1/2" ID X 1" long. Then drilled the inside pulley hole to 5/8" and pressed the bushing into it. The mounting bolt was metric so I turned the shoulder down to 1/2" allowing the bushing to slide on the bolt. Now, no more problems at all with the bike .
The manufacturer claimed the motor bike would do 100 to 150 mpg. No way; it goes 60 to 70 mpg, but I'm happy with that. Certainly has cut down on gas purchases.
The highway drivers have been very courteous and cautious. The bike zips alone at 20mph, but will do 25 and has pulled every hill I've challenged.
Get one, have some fun, and save on gasoline purchases but be very careful in the traffic. To help motorist see me, I purchased a bright orange vest to wear while riding the motor bike .
