Photos & Bicycle Builds

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, so I went with a foot actuated friction belt clutch using the stock tensioner, and it turned out to be a good way to get a 2 speed anyways. Considered a cvt but again, those are also expensive, and total my build is just under $150. Can pop a wheelie...

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

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 them. Top speed at 6800RPM is 25mph. Hop on, pull start, give it some throttle and go. It feels zippy and easy to move because it's so small. my beer holder and GPS speedometer I built my own extra long throttle cable out of an old brake cable

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 groundbreaking build wise. It's just always been a solid runner, but sat for a while until recently. I'm showing off my new cockpit and contact points here, but the carb is newer and low hours, the front wheel was recently upgraded, it got fresh rubber, mr...

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 case. With the case opened I can run a drive shaft inside the case turning the original input shaft with Lovejoys being driven by a a chain from the Preddy. This keeps every thing in its original places drive wise. Much less complicated fab wise. And...

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 also (thats a 1st)

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. There's also a VM18 Carby and ngk bh6s on there now and she's running way rich with 30 pilot and 75-85 main, next step is to see how the 65 does (70 is stock) and pick up a couple smaller pilot jets. Right side "brake" is my killswitch. I got in a...

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. It's definitely a interesting find and would like some sort of assistance or advice on how to best build this beast bike.

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 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" bike with rear box to hold the battery and my ice chest Predator 212cc with Stage 1 improvements Comet TAV2 torque converter Custom jackshaft and sprockets/chains (shown in picture) Front and rear lights, brake lights, turn signals

103 miles on the odometer today, coukdn't be more pleased. For the last 30 miles, last few days, I've been exploring ATV dirt trails and really beating this thing up like a real dirt bike. Getting a little dirty now, I like it. I had to split and join the pipe, engine tilt put it into the frame. The difference is pleasing, it'll growl up mild hills in higher gears, seems to help low end a lot. I plan one more gear change, right now low end is 9-17-9-36-32 from motor to wheel. I have a 18 sprocket coming for jackshaft engine side. If that's not enough I may swap my crank drive from 36 to 30. Honestly almost there now. I locked out 6 and 7 sprocket on rear, only shifting thru first 5. Still, it gets to 30mph. Not more, best I saw was...

Here's my Cranbrook build. What a freaking learning experience 😆 🙂 Jan 2020 project started 2021: SKIP looks different everyday with new parts from stuff breaking 🤯😆. Ok just one photo Now 2022: Not tampering with it anymore it runs great finally after 2 years 🙂

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

When I wasn’t able to find seat post struts I decided to see what I had laying around and came up with this. I found a piece of 3/4” aluminum tubing and was able to bend it with my 1/2” EMT bender then used a -12 AN hose separator to attach it with. I had to grind away some of the inside of the hose clamp in order for it to clamp down tight enough. Also I squeezed the tubing under the seat with my vice and aluminum jaws

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

Just finished building this bike for my employer. CDH GT2A gasframe Ruff cycles forks,bars,and stem Sturmey Archer xlfd drum brake hubs, 3 speed on rear Husky double wall rims with 12g spokes with Maxxis Hookworms Smolik performance budget minarelli with a mikuni vm20 carburetor and yasuni R1max exhaust. Sickbikeparts.com shift kit. Should be a fun little ripper.

well i got a snowmobile engine for christmas. i was gonna put it on this vehicle, but when i ratchet strapped it to the scooter and started it the scooter vibrated across the driveway. i had this lil 2 hp briggs that i did a "restoration" on (added a decal and jb welded the fuel tank). anyway the drive is self explanitory. im machining a pully to fit the rear axle, and then i just build a belt guard, wiring, foot pegs, heat shields and an exhaust system... now i just need a good name for it

What's ur preference on tire profiles? Narrow and sleek? Or wide and knobby

When I arrived at my shop this was waiting for me. The attached note read "we thought you could make it work". No name or info other than that.
