Photos & Bicycle Builds

Found this little guy and made an unplanned purchase. $300 on craigslist! Came with lights and blinkers and a light-up skull too! It isn't ready to ride. Gonna swap on some disc brakes and good wheels.

I built my first motor bike about ten years ago: 1960's Galaxy Flyer. I sold it a few years ago when we moved. I miss riding it so I picked up a dirt cheap rusty Murray Monterey at a flea market. It took a torch and lots of PB Blaster to take it apart. There was so much rust I suspect it was found at the bottom of a lake while magnet fishing. :) Here's the de-rusted Murray put together for the first time and working out the bugs. It ran extremely rich out of the box. This new motor has much less vibration than the Bike Berry motor from ten years ago. This is a before photo all torn down for rust removal. Soaking parts in vinegar is a good cheap rust remover. Torn down again for painting. The front motor clamp-on mount...

Picked up this Schwinn AL Comp 27.5 for $50 USD at the neighborhood pawn shop. I think the seat is worth that much. It looked like it's previous owner had some addiction issues. When I would turn the bike over, I'd hear stuff making weird noises inside the frame. Sure enough, removed seat and there was a buffer spring between the seat post and the bottom bracket, doing absolutely crap but making noise. Anyhow. The engine was a very tight squeeze, a Zeda Firestorm 80. The rear mounting block, I had to cut, leaving only about 3mm between the base and the apex of the seat tube arch. Even then, I had to grind a little off the center fin on the head to make it all fit. I wish I took pictures of the block I cut. Here is a...

Went for a large ride on the yd, mostly crusin, went to a buddys house then just rode for fun, hit 48mph with nt which is pretty cool. Probably gonna be one of the nicest days til next spring, 38 degrees feels way better than the 24 I rode to school in!

This is my bike. I post more photos on here if people want to see more. Everything is custom on it. I didn't know what look I was going for until my friend said it looked like a 1970's bobber which I like that idea.

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

The LD100 dual head is too thin and will warp from heat. I replaced mine with a Smolik head. Used PZ20 carb and jog exhaust pipe. 25% of piston blocks intake at bdc but I still get 10,900 rpms and 52mph with 11/36 gearing. Ran 40:1 Lucas semi synthetic from day one. I used a Schwinn Jaguar.

Hey guys, after recently introducing myself and my cruiser build, today I want to show you my first motorized bike. It is a Nirve Switchblade Chopper, 53cc - 4G 1B Grubee Engine with a jackshaft setup. This is the bike I learned how to build a motorized bike with, which means a lot if trial and error. I am glad I finally got it dialed in. A milestone in this build was to understand that everything over 6800 RPM is redline and causes drastic vibrations. My bike kept falling apart until I learned this. Then, not being able to full throttle anymore (before I was doing over 9000 RPM to reach 30 MPH) I was looking in to a jackshaft conversion. I needed gears to reach max speed within a normal RPM range. With the frame being a little...

The old reduction friction drive has been removed and tossed on a shelf. It was fun, I learned, but its wore out. Stripped bike to its bearings, cleaned, lubed, new driveline chain and cassette 11-32 / 7 with long cage derailleur, trigger shifter. Dumped front derailleur. Stole hookworms from wife's bike. 🙄 Added BBR 48cc. And that's my stopping point. There's no way in hell a chain will line up w/o power idlers. Kinda knew that anyway.... Course, now I whine, pout, wife says I can get a shift kit for xmas. 🤣😂 Hope I got everything right, I watched a video b4 installing those circlips, one for the clutch too. Was planning to break it in on a trainer stand, but as I can't run chain it has to wait. Do I need a load on the engine...

I went from a 50cc 40mm cylinder and piston to a 47mm cylinder and piston but now I'm having trouble getting it started. It was pretty simple the only trouble I had was the cylinder bolt pattern was a little different but all I had to do was take a little bit bigger drill bit and drill both sides of the cylinder about a inch down and I also had to make my crank case a little bit wider for the cylinder to go down all the way which adding another gasket took care of that and a couple of brass shims on each side of my crank

Was getting my bikes out for the upcoming move. This bike hasnt seen the light of day for years. Thought I take a few pics. The build is basically finished, just a million little details. The Villiers is driving thru the bottom bracket directly to a clutch on the right side to a 3sp IGH. I did something I have wanted to do but have never done, is to convert a coaster wheel to a front brake. Notice also where the rear brakes are. Should be a cool old school ride. Its a true 100cc. The old Villiers are smooth, torquey runners that dont rev overly high. The engine is an early 30s and the frame is a 36 Cleveland Welding step thru.This one may reach forty. Will be badly under braked at that speed, will keep it as an easy going 30ish cruiser.

Hi. I'm new here. I've built 2 so far and had a lot of fun doing it. The first one is a new Kent 26" Seachange frame. It has a wheel base of about 42.5 inches. The 2nd build is an old Huffy 26" cruiser that used to belong to United Airlines out of San Fransisco CA airport. They were all disposed of about 20 yrs ago, and a buddy of mine passed it on to me. It has a wheel base of about 45.5". They're both pretty much the stock kit.

Hello, This is my second motorized bike build, the first was a Dolomite fat tire, but it was stolen. Grr, guess they needed it more than me. Have to dig for pic of that one, but anywho.... Just installed a China girl on the Western Flyer Newsboy Special....

Motion Pro Braided Vinyl Fuel Line | New Extended Intake

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!

Here’s the starting point just got it for 5 dollars.

It may look like something sold in one of those out of the way shops with the windows painted black, but trust me. It's my new intake. The silicone tube comes premade with this 45 degree bend. I'll have to cut it to size but I'm hoping this solves my problem. Now it's time to get the bike out as is and test for leaks.
