Mountain Biking - ic engine powered bike

i have been looking for plans or any already built petrol powered bikes
so far i have found none that look any good, some have engines over the back wheel and others with the engine in the front wheel
i have started work on a powered bike and just wanted to know if any one could give me any help, has any plans or has built a powered bike
thanks:)

How about one of these?

Although not a reciprocating engine, it is an internal combustion engine. It looks to be a fairly nice and clean design.

Petrol powered bikes? That's a pretty generic term....

You're defeating the purpose I think. Why not just get a mo-ped or a motorcycle. Why would you want to make a bicycle with a motor anyway? If you don't want to pedal, why have a bike?

It scores big bonus points for the flame as well.

to save on fuel costs, get a girlfriend and a tandem, then let her do all the pedaling. THAT's the way to roll

Moped and Motorcycle requires a license I believe.


Just ride a horse. Great power and can go fast. But watch out for the overpasses! =)

mopeds I don;t believe require a license as long as it's pedal start

Well.. I donno about all state laws on the moped thing... but in cali, I saw someone with a moped similar (in size and look) like this and it has a license plate on it.

Probably up to a certain size or weight on the moped then you need a license? And I do think you need the ride it on the street instead of sidewalks, because you cant ride gas-powered vehicals on walking areas.


Just pay a some $10 fee and get a license because a police ticket would be at least a few times more expensive. AND WEAR A HELMET TOO!

California (and most states I think) allow you to drive mopeds/scooters/vespas/gas powered bicycles without a liscence if the engine displacement is under 50cc 's.

There's a lot of 2-stroke kits you can buy off of ebay (really cheap chinese motors) like this:

As of 2005 they are no longer legal to import due to emissions laws and I imagine being so cheap they won't last very long (or work at all) so buyer beware.

I like the Bionx system for both weight (15lbs) and good modularity. Still having trouble parting with $1700- for the L-Ion version.

Here is a great place to buy a petro-solution: Five Flags Cycles (http://www.fiveflagsmotorbikes.com/BicycleEnginesGasoline.htm)

Bought the electric shopping trike for the wife from them. Best price anywhere.

My part of Texas says if it runs on anything other than human power (if you have a soylent green motor you are good to go) it has to have tags and a license.

Ive only seen electric mods for bikes.

lol my friend buil a bike with a chainsaw motor, that thing givers its sweet.

I saw a guy on a X-mart chopper bike that had a wiper sniper engine strapped onto it. Looked hilarious! That guy was FLYING too!

ok im toooooo young to get a moped and will drive it on private land so no worry about it being legal

Then there is that engine buil tinto the front wheel of a 26" bike that's soon to be available, will work with any 26"er...I know I saw it on bikeforums, can't find thread!

Check oput the French Velo Solex (http://freespace.virgin.net/stones.ukp/velosolex.htm)

If you don't want to pedal, why have a bike?

Exactly how I feel about lift serviced riding

more info i might actually do this :) don't forget your helmet lol . i bet u will go through brake pads and tires quicker though...

well the brake pads lasted longer than the engine. it overheated 1 to many times and is to pircy to fix. i got some pictures and am now working on putting a sinclair c5 motor on instead. it was very fun hit over 30mph and i did not get caught once. hehe.

ok the pictures wont upload. but believe me it is cool

IC-powered bike - - hmmmm . . . think I raced one of those in the late '60s . . . .
