Pictures of motorized bike projects and bike builds. Vote for the best build!
Well i finally decided to purchase a engine kit for a beach cruiser. I found the cruiser on facebook marketplace for $25, and it was delivered. turned out to be a brand new bike. As for the engine kit i went with a zeda 80 firestorm. I had one issue with the exhaust. it would not fit around the bikes front downtube. Tryed the motor adapter, didnt like it. ended up finally with a ball peen hammer.it`s there and not touching the frame now. i have not started it yet and still needs the chain...
New build of mine.. had an idea and ran with it. Grabbed a couple ideas off here as well, like the fat arse seat!! 🤣 Fun build but the jackshaft kit took a little tweaking. Made a guard for the chain that doesnt look too bad. Was painting it during pics. BT100 motor (80cc) is what this project is sporting. Runs decent for now, Grabbed a larger tank for it that i will install after driving off the first gallon.
well the little 29cc bike is being retired. it is a sad day. BUT, dont fear, my projects always come back better. in this case, i have an almost brand new 5 hp briggs. it has less than an hour of use, and looks factory, no dents not even any dirt packed in the fins, it just happens, that it will fit in the frame of the old 5 speed bike. now i know what you all want to know, and that is, it it gonna have gears? that is a definate yes. i feel that with this power, the gears are gonna be...
Hi guys! Here's my first attempt at building a motorbike. I had got this kit thru bikeberry but found the engine had a good bit of defects. Of course I didn't figure this out till after the engine blew and I dismantled it to discover the flaw. Ended up just buying an Ebay 66/80cc China doll, and before even mounting it I tore it down and replaced everything that looked not so well made. Which was pretty much everything. Its running good but im still breaking it in of course.
I built this bike in 2010 and ride it off and on since then. It operates flawlessly and only issue since 2010 has been new chain. You can ride it with engine running or engine off doesn't make much difference other then weight of motor system. I am getting up in age and don't ride much anymore due to health issues. My question is would anyone have any interest in a turn key moterized shifter bike for about 750. I hate to just hang it from the ceiling and not be used. I am located near...
I've been watching my younger brother tool around on his motorized bike for a couple years. My wife and son had visit to grandma's in San Diego coming up so I figured it would be a good time to give it a go. I'm a big guy (6'4", 285lbs) so this isn't the right toy to try to set a speed record on, but I figured I could put together a fun cruiser for pretty cheap. I had an original budget of $300... but after carefully considering the potential safety issues of the bike, I decided on...
well ive got a new scooter. $25 bucks for the rolling chasis. i swapped the stock rims for 500CD rims (their lighter and stronger) i have a rear mount, off my alternator project, and i think a 2hp briggs with a centrifugal clutch will fit real nice behind the seat. this will allow me to have a standup/sitdown, and it will be more driveable, and it wont burn your leg(s) it will have all the plastics too. it wont be a speed demon, just something to putt around, and it will have good breaks...
Hello all. Just joined today and thought i'd put up a few pics of a couple of my ongoing projects. I will if anyone is interested putting a breakdown from start to finish on a couple of them some time soon. both are unfinished. the smaller one is running off a 250w motor but im putting a 500w in soon. The large one was built in the 1960s originally with a Villiers MK1 Midget engine in it most of the parts are from 1950s,60s motorscooters. I am converting it into a 2000w electric one. the...
Long time lurker, first time poster. Thanks for all the great info here. With y'all's help I've built a couple bikes for my transportation needs. The black one is a KHS Alite 40 with a Honda GX35 Staton friction drive running a 1 inch drive roller. I've swapped out the mtb tires for Fincci street rubber, Kool Stop break pads, Shimano trigger shifters, and a dual brake lever. It's my daily work commuter when it's dry out. It's been perfectly reliable and a comfortable runner over all with...
I bought the engine kit about year ago knowing nothing about motorized bikes. I have bicycle and 2 stroke experience so that helped a lot. I am having an absolute blast planning and building. Let me know what you think or what I should do next.
Hey guys just pick up this new bike and cannot find any info about it. It looks just like a cranbrook. The company is called Honest and there is a sticker says manufactured by Cycle Force Group. Anyone heard of these bikes before? I’m also not sure what I wanna do with it. Any ideas are appreciated! Thanks!
I need ideas on what to put on this bike or what color should I paint it
I know this has 4 wheels but the build is in the spirit of what we do here. A friend gave me a fairly nice Ezgo cart that needed too much to repair the electrics. Having a new 212 and torque converter in boxes its a no brainer. About a zillion of these have been done, but as usual I opted for the hard way. Not wanting to build all the intricate structures most folks do I opted to use the case of the old motor. Required a lot of tedious, actually a little over an hour, cutting of the motor...
Still my same bike but my first thread is so old and it's come quite a ways since I first put it together, so I wanted to start over with a clean fresh new thread. Here's my current build, based on a 1997 Gary Fisher Mamba. Here's how she used to look: And here's what started the change: After this happened, one thing led to another, and, well...here she is. PARTS LIST: Engine -66cc China Girl --No-name billet head --No-name MZ65 replica --DIO reed valve --19mm OKO carburetor...
Ok, it took longer than I expected, but now it is done and almost through break in. Took the Huffy Causeway (decent older cantilever frame) down to the frame, cheap rattle can paint job, took all the rust off the only components I used; crank, chain ring, seat post and stem. Could not get the chain guard on as the motor is too low. New handle bars, grips, aluminum twist grip, dual break lever with stop light switch (future upgrade to lucky owner), all new cables, upgraded bolt on tank...
Got this frame about a year ago for $5, very rusty. Initially I put a chainsaw engine on there but being rather used and 2 stroke it ended up dying, so I found a snowblower in a junkyard with a 13hp tecumseh on it that sorta sputtered when I threw some gas in there so I bought a carb and welded the frame around it out of an old stop sign post. Was thinking about a centrifugal clutch, but all the cheap ones have reviews of them burning out and any good one with a 1" bore is like $100 or so...
Hi all newbie here from Australia my name's Sam and I'm 30 recently after a few sleepless nights I thought it was time to try joining two cag 49cc engines together but then ran into a problem joined the crank shafts together so I have come up with this. Using two motorised bike magnet and Magnetos. The pros easier to join the shafts. Cons no cooling. But hey it's a work in progress Video here https://youtu.be/VRgzHh9aO1U
Hey friends, I just wanted to share some of my recent upgrades on an old build I originally put on the road back in 2007. It's the same motor and OG SBP Shift kit that's been on it since day one. This is just the latest in a succession of cylinders I've tried on it including some moped jugs, but the more modern China Girl jug is holding up real well and makes more power I think than my original ever did. Ports look a little more open especially the transfers, but none of this is...
Here's my first (for myself, I have put together a few others) build, an imaycc 80cc kit (came with the little bike computer) on a Kent seachange. Swapped for mag wheels. Removed rear coaster brake, rear dropouts are too narrow to put both a sprocket and a disc brake on so I just have a front disc brake. I welded on one of those universal disc brake adapters to the front fork (just screws/friction don't keep the caliper and bracket from twisting and moving) and stopping power seems adequate...
