The Great MB Photo Challenge
Here's a fun little topic, we get to see more pictures. The way it works is, the poster, (me) post a picture of my bike with some item. Then the challenger post a picture of their bike with the same (very similar) item. Then the challenger post a second picture of their bike with a new item for the next challenger to match. My first one I'll make easy my bike and a car. GO!
The Urban Fatbiker 2025 Fleet
Always the excuse to post pictures, my fleet of motorized bikes is ready to serve me. A Fleet must meet the bare minimum of three: If your fixing on one, And you break one, You can still ride one. More is better, but some spouses object. 🤨 With no more yapping, here's the fleet. Buzzbike! 48cc jackshafted to a 6-speed cluster, full navigation light set w/battery good for hours of riding. Schwinn Ranger steel frame, everything replaced with quality stuff. Its been very reliable, the drive is almost bulletproof. Dual collared and dimpled shaft on a reinforced double-plated highly modified SBP bracket, quality bearings, LFaster freewheel crankset with a DITKA ebike HD clutch bearing. The odometer shows over 1600 miles, that's with the...
Mickey's Walmart Skyliner
Here's my bike, a $149 Schwinn Skyliner from Walmart with a Kings "80cc" motor kit. This bike has front suspension (springing really as it doesn't seem to have any damping effect). It has a bit too much space in the diamond and a 1 1/2 inch downtube so it does require fabrication of a front mount. I've ridden it about 500 miles and everything is still straight although I broke all 9 trailing spokes on the left side within a few days. I was too paranoid when tightening the sprocket bolts and that allowed the sprocket to work the spokes to their death. The narrow handle bars make it hard to fit all the controls on and I think a more classic sweptback bar would allow an even more comfortable riding position. Since I set the bars as...
75cc "100cc" Build
My third gas powered build I built this to be my road trip bike, it's bored 49mm with an iron sleeve. Port timings were perfect out the box! I made the exhaust out of a copper pipe and a baseball bat, the chain tensioner is a skateboard wheel. Put a scooter gas tank on it. Went over 50 mph (downhill) it was TERRIFYING (I've got $90 in this bike) I love it 😀
Modified Beach Cruiser
I rebuilt an old/abandon 2 stroke 66/80cc engine, that had been in the corner for ages, rust parts in a box. Then deided to use my trusty beach cruiser as the donor, my vision for the project was kind of a board track/early 1920s bike, the frame had to be cut and modified to fit the engine and the forks had to be dressed up a bit, using some of the lessons learned from preious projects the chain tensioner bracket and rear carrier brackets with a scratchbuilt carrier, I tried to be clever and make a way to have the cables go through the frame, it worked before, but I did'nt do my homework properly and only one managed to work out, but it's better than none. In a pinch I decided to make a fake tank out of 3/16" plywood and put a small...
I mentioned my project bike in another thread and some people showed interest in an update as I make slow but steady progress on modifications such as porting, planeing, jetting etc. (maybe Sturmey Archer trans upgrade?). This thread is where I will make those updates. Little background: bought a 50cc kit off amazon for about $120. Replaced all the hardware with good stuff from the hardware store. Upgraded to a CNS carb and a little banana expansion chamber with a muffler, as well as a 50 tooth. There is more on the bike itself if your interested in this thread Off Road Bike Builds. Been a good little motor for me but the lack of displacement is leaving more to be desired. And the reason I don't just buy a Zeda or PK80, I guess enjoy...
MOAB
I bought this Merlin road racing frame used. The bicycle was built around it by Red River Cyclery in Alexandria, LA. The engine is a custom K1260 top end modified with a Smolik head built by MFL Bikes out of Port Orange, FL. It's going to take me a while to build this, but I will update this thread when I make progress!
Its cold out there. Put on the gear. Get out and ride.
I suited up and got out today with temps in the 30s for a ride downtown. I didn't use my ski pants or heated soles, just my jackets coats hat, and gloves. I use a heated vest inside it, it does a great job. Hat did OK too. Legs and feet, OK. The only thing not good were my gloves. My hands froze. I stopped a lot to warm them. My eyes watered a lot in the wind too. I ordered a pair of heated gloves. What else ya use to ride when its freezing?
Off Road Bike Builds
I see a lot of sweet cruisers around the forum and I figured it would be cool if we had a thread for bikes with some heightened off road capability (If anyone besides me has built one). I love riding on canal roads and in the desert with my bike and wanted to see what some of you guys have built. I'll start with mine, My friend and I built this one, it's a 1984 Schwinn Impact (chromoly steel frame) which was a mountain bike back in the day. This was back when Schwinn had just stopped making bikes in the US. Anyways, I installed a 50cc I bought off amazon that with regular maintenance, has served me well so far. Since then, I have installed some modifications to make it better suited for trail riding, including a kind of expansion...
Am6 Felt cruiser

Faker build
Just a temporary build. Minarelli hybrid with Athena Sport 70 top end. It's fast running just over 60 mph on 10/36 with 27" tires (26x2.5 Hookworms are about 27.25" tall). Swapping the vm20 for a Tilloston clone when the return springs get here. Not my favorite bike lol.
What I’ve acquired to start to get my hands dirty.
Moving furniture tomorrow to get a desk and shelf for better organization and all. While at my folks house, grabbing the bump motorcycle mount. My dads got a Brian Stratton engine on some thing that he’s not even using. It’s just sitting in the back. Instead of wasting money, buying something online on marketplace or even from Harbor freight I’m gonna snag that tomorrow when I go to get the furniture. I’ll also post a pic of a clothing rack that was supposed to mount on top of the dresser when I was learning to weld. The first engine one first motorized bicycle projects, but I’ve got something bigger and better to keep me focused so I don’t do stupid things. And then I’m also acquiring essentially two more bikes. The bigger thing that I...
372xp Big Bore w/ Tillotson carb (a true 80cc)
Hyway 372xp big bore cylinder which would be for a Husqvarna 372xp chainsaw (52mm x 38mm). The crank bought by Don Butler initially claimed to be balanced to 52%, turned out to be only 35%. To rectify this, I bored out the original holes and drilled them deeper, achieving 50% balance. The reciprocating mass was 156g, and I removed 23.4g to reach 50% balance. I inserted brass bushings (10x12x8) in the piston to accommodate a 10mm wrist pin so I could still use a wrist pin needle bearing and not a 12mm wrist pin and a bushing on the conrod instead. The case is an undrilled YD100 case (super special), and I modified the transfers because the original transfers are horrific. The 66cc/69cc has better transfers. Additionally, I added an M3...
"Dhampir" motorized bicycle project
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 bicycle - size, weight and the ability to ride pedals. From a light motorcycle - the dynamics of acceleration and cruising speed. All this - with weight and dimensions, under which it can be stored in the apartment. Of course, because is a...
