49cc Pocketbike motor on a bicycle?

[KULUKIN]

I'm starting a new project motorbike and wondering,
Has any one here tried mounting a pocketbike motor to a bicycle?

I looked at a pocketbike today and it used a tiny drive chain, I'd like to convert this to work on a bicycle, prolly using parts from Staten-inc, or any other ideas?
I can weld and fabricate, but mechanics is not a strong suit.

Absolutely.

Haggard wrote a tutorial on the subject.

i've used the "cag-47" before and am getting a mits-copy 49cc (X2) soon...on a gebe drive...you won't be using the pocketbike clutch-drum if it comes with one. so long as you match internal clutch size to the drum of the MB-system you choose, you're good to go.

pbu has some mean looking engines alright...you can also start small and get stock engines as low as $70 for the cag & $120 for the "mits."

 

[KULUKIN]

would you recommend buying a whole bike and parting it or just a motor and specific parts? other suppliers? and would Staten-inc have my parts?

 

[augidog]

search the web for "scooter engines"

you can easily find only-engines many places...maybe someone can post some links to reasonable pricing.

and, i represent one of the "other suppliers"...it's a straight bolt-on to the golden eagle rig. most drives that use a centrifugal clutch should be an easy match, also.

careful: the stock cag-47/49 uses a bowl/float carby, hard for positioning a tank on a rack-mount. as you see by pbu's offerings, there are DIY intake upgrades available. the stock mits49 (also in 43cc) uses a diaphragm carby, usually comes with a basic muffler, add a tank and it's ready to go.

:

Yes, but first a very important question.....
How and where are you planning to mount the engine?

In the frame?

Rack mount?

Or?

What kind of bicycle frame are you planning on using?
Wheel size?

A mate of mine is building the ulitmate in frame 2 stroke motorized bicycle.
We considered using those very engines you are looking at but there is a better solution.

God I Love this PLACE!!!
Thank you all 4 replies and Q's,

I'm flexible on this, but..
I'd love to copy the Chicara moped: engine on side by rear wheel, just above rear triangle, build a beefy mounting bracket(sort of like a rack), mated to a Swobo Folsom, with chain drive.

OR/and

A boardtrack replica from a 21-22" 1990 Stumpjumper frame, engine mounted in the triangle, w/ chain drive.

I have a Schwinn Cruiser with Happy Time, love it but want another.

I love the look of those motors, details & hp, so if it fits and I can weld some mounts and bolt on some new gears, now that would be kulukin.

LOL, hey, I have an almost brand new 50cc scooter engine with cvt already attached. Now just have to figure out what to do with it.
