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...
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...
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...
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...
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...
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...
I saw this BMX laying around in my buddies yard.. "can I have it and put an engine on?" "you can do to this bike whatever you want" 20" wheels I used round steel from ace hardware, flattened the ends and drilled a hole for a screw. Then I was able to mount the engine mount over the rear wheel. A twisted piece of flat steel prevents back and forth movement. That one is slotted so I'm able to move things around later on This bike has massive steel drop outs so no problem drilling through...
I Usually Do OCC Choppers But I Decided To Try Something A Little Different This Time, Still Sticking With The Chopper Theme But Yeah.. Here It Is. Needs Little More Work Gonna Make The Cosmetic Tank A Actual Working Tank, Gonna Switch The Chain Trans To A Grubee Belt Trans And Gonna Make A Long Pipe So It Exhausts At The Rear
I posted this bike last year when it was all electric. Added gas but also wanted to keep the electric, and have it even more functional. Now has regenerative charging of the battery when running on gas, can run on gas, electric, pedal, or any combination. With both gas and electric I even have both front and rear wheel drive (only one rear wheel is driven). I really don't know if it would make it, but it should go pretty close to 55 or sixty. It turns 1560 rpm at 30 mph. Worksman Mover 26"...
Was not so fun to ride around on a bike with CRF plastic on, so I decided to rebuild the slightly more MTB "bike" with engine .Change from 50cc to 66cc
Hi all, some of you have probably seen me floating around the forums a bit, and to all who have helped me in my venture (special shout-out to DAMIEN1307) thank you so so much, I couldn’t have gotten to where I am without y’alls help!
It's been a hot minute! Or like 10 or so years since I've been on this site...But I've been busy with life! I started this bike in the Fall last year and just finished the fabrication last week. I've been testing it and now it's time to disassemble and paint. The front-end suspension is a design based off an Atomic Zombie build. At first it was like trying to steer a beach ball, but after a while I got the hang of it and can do a U-turn without putting my feet down.
Hey guys this is Cruz from Down the Block. I recently obtained this gnarly bike off a friend of my family. At first the bike had skinner forks which were probably taken off a Schwinn bike and had a slimmer tire. But I swapped the front tire and put on a 20x2.80 tire just for now. I plan on switching the forks out with OCC chopper forks. I'm having trouble figuring out how to install brakes on that wide back tire. And I don't really like the fact of having a pull string to start the motor...
Good day to all! For a long time I wanted to post my topic on this forum. First, by the name of this monster. What is a dhampir? We open google and find something like this: "Dhampir is half human, half vampire." Dampires is generally portrayed as one with all or most powers of a vampire, with few to no disadvantages." If it is easier, then the concept of this bike is simple. Ideally, it should take the best from both kinds of transport and, if possible, not have their disadvantages. From...
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!
it just barley fits. i know you are gonna have questions of how im gonna pull this off. watch-n-learn. btw i said specificaly i wasnt gonna do this, but here we are. im gonna need a serious wheelie bar on this one
Thought I would post pics of my long awaited full suspension build. Looks like the biggest problem now is locating the card. I got most of it fabricated until more parts show up. Going to build the wheels next followed by pit bike hydraulic calipers
