Has any one ever made a motorized bike with like a 80cc motor?  If so was it hard to install the motor, and what engine kit works good for a fair price.  I heard that the boygofast  kit on ebay works fine.  please leave some feed back! ???

the BOYGOFAST kit on ebay is like 160$.  and a beach cruiser from commi Wallyworld is like 99$.  So for under 300 bucks i can have a vehicle that will get 130MPGs.

Hi.  Yes I have purchased a 50cc gas kit off of ebay with satisfactory results.  However, for 99 dollars don't expect the world.  As far as installation goes, very easy...very simple, with some very basic mechanical skills required.  Kit turns out to be turnkey, nothing else required but loading in some gas.  Put 200-300 miles on this (ouch), recommend a bike with good shocks and comfortable seat.  Have since switched to electric (far better) model Phoenix Racer made by Crystallyte.  Had some issues with motor tolerances (slight wobbling in the bearings), waiting for unit to come back from factory.  Really love it, hope they fixed the wobbling issue, otherwise - so far in 260 miles I have managed to save $75.00.  Not bad!  Drive 11 miles each way to work at 35mph with moderate peddling - as well as ending up with some fuel reserve.

When I was a teenager (30+yrs ago), I tried to add a chainsaw engine to a ten-speed bike. One of my friend even welded a frame on the back to hold the motor. I never did get it working though. Engine needed thousands of rpms to get going. Needed a flywheel to keep idle. Stick with a conversion kit! Somebody already worked out the kinks in the design.

holy crap, are you saying that you can ride that on the road in the states? here in Canada, you need to have a licence, insurance, plates, everything that a full size motorcycle needs.

In Maryland, its the size of the engine. Less than 50cc is considered a moped or powered bike. Driver must be 16 or over. Bike needs nothing. 50cc or more is a motorcycle and must have tags & Insurance. Driver must have valid motorcycle license.

HERE is the DMV LAW IN CALI USA if anyone finds it good info


Quote
Motorized Bicycle

406.  (a) A "motorized bicycle" or "moped" is any two-wheeled or three-wheeled device having fully operative pedals for propulsion by human power, or having no pedals if powered solely by electrical energy, and an automatic transmission and a motor which produces less than 2 gross brake horsepower and is capable of propelling the device at a maximum speed of not more than 30 miles per hour on level ground.
(b) A "motorized bicycle" is also a device that has fully operative pedals for propulsion by human power and has an electric motor that meets all of the following requirements:

(1) Has a power output of not more than 1,000 watts.

(2) Is incapable of propelling the device at a speed of more than 20 miles per hour on ground level.

(3) Is incapable of further increasing the speed of the device when human power is used to propel the motorized bicycle faster than 20 miles per hour.

(4) Every manufacturer of motorized bicycles, as defined in this subdivision, shall provide a disclosure to buyers that advises buyers that their existing insurance policies may not provide coverage for these bicycles and that they should contact their insurance company or insurance agent to determine if coverage is provided.

(c) The disclosure required under paragraph (4) of subdivision (b) shall meet both of the following requirements:

(1) The disclosure shall be printed in not less than 14-point boldface type on a single sheet of paper that contains no information other than the disclosure.

(2) The disclosure shall include the following language in capital letters:

"YOUR INSURANCE POLICIES MAY NOT PROVIDE COVERAGE FOR ACCIDENTS INVOLVING THE USE OF THIS BICYCLE. TO DETERMINE IF COVERAGE IS PROVIDED YOU SHOULD CONTACT YOUR INSURANCE COMPANY OR AGENT."

Amended Sec. 1, Ch. 804, Stats. 1995. Effective January 1, 1996. Supersedes Sec. 2, Ch. 342.


That electric kit looks really spendy,  I just  looked at the price and they start like at 800$ WOW thats a lot, for me.

A friend of mine has put a whipper snipper motor on the front wheel of his push bike. Though he uses it to go the train station mostly. I think you can take it on if you buy a ticket or try for free, and then have it at the other end. We adapt and evolve, he lost his licence for a long long time.

i am talking to a company right now in china where i can buy them engines for the boat load..... kinda afraid to deal with people i don't know tho. They come in pallets and you have to spend several Gs at a time.
