Photos & Bicycle Builds

Pictures of motorized bike projects and bike builds. Vote for the best build!
 
Hello All, After MUCH sweat and lots of help from many of you on this forum (especially Aleman), Blackjack is basically finished. I took progressive pics along the way showing some pitfalls with the clutch/gearbox, etc that I will happily share with anyone interested. I'm now thinking about a mini sidecar project to haul cargo.
Hi im from Oz and this is my 2 stroke Schwinn in progress... I've done the usual mods including a severe dose of heavy porting. I got bored so I polished the engine covers to a mirror finish - I reckon this looks much better than the same crappy slotted cnc covers that everybody has.... I also did a little porting and port-matching with the inlet manifold... I've ordered a aftermarket cnc head as well as a 4 litre fuel tank that should arrive very soon... I'm gonna give the head a skim to...
 
Hello All… new here. Wanted to post a build thread of my new bike. For now I’m just going to upload a few pictures. I thought I had already posted a few for a build contest but I can’t find them. I guess it was a different forum. I’ll start with the latest then when I have time I’ll post a few pics with an explanation of how I put it all together. Thank you for your time and allowing me to be here. Please forgive the sequencing of these photos. I’m new at this and haven’t figured out quite...
 
I have this little 5 speed cruiser, let's see where it goes.
 
Hello folks today I found a junk bike in an alley that I thought would make a great motorized bike. So I bought a motorized bike kit. Before starting this project I had accumulated a fair amount of parts. Going to try to post this in real time well after I finish what I’m doing. this is what I’m starting with
 
This is my bike. I have had this ride for about 4 years. I am always upgrading components or improving the overall aesthetics. It’s a rather high performance build with “show car” attention to detail.
 
I spent a while planning- getting parts- getting cash together- assembling and modifying. This thing is really looking good I think. Let me know what you think
 
I thought I'd try a little R&D and see if I could make one of these. Okay, half done!
 
Here she is! the Frankenstein build. This is the 2nd engine to mount on this frame. I got about 1000 hard miles out of the last build before i believe bearing issues took out clutch. I reused some parts off the first build such as the carb and rims, but otherwise everything has been replaced, even the circlips in the motor have been upgraded to the CW10. Chain is #41 and fits perfectly with zero rubbing, although close in places. I have nothing bad to say about these PK80 motors. I was...
 
Preamble to this - I have had a basic straight kit-build in the past decade, and an aborted build that was much higher grade, that had i lost interest in/evolved into the build being documented right now.. over a 5 year time-span. I had stopped 'building' .. but i didn't stop monitoring/buying up parts to progress on another possible build. As such, in putting it all together when the project came back on the bench, i had minimum needed to buy, more a matter of pick and choose. In my...
 
I'm going to use this little broken down atv for my next build. I rebuilt the motor and got running real good, starts on first crank. Quite a nice sounding little motor. I bought a whole new wiring harness for it because old one was hacked and broken.
 
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...
 
Building a motorized bike is pretty simple. Unless, like me, you want a shift kit on a Mongoose Dolomite. I've had to customize the rear motor mount (shift kit housing,) fabricate some spacers and a customized front mount plate. Having solved those problems I ran face to face with the next problem which didn't surprise me. I'll have to take the shift kit housing off the motor and do some more customizing to it. When I solve this problem it won't be long until I'm faced with the next...
 
Raleigh Nitro 10spd circa 1989-1993 Dmr Moto tie'ers with only 15psi up front, 18psi rear. kevlar front tie'er liner, purple rubber liner at rear. front brake not necessary, (try removing all your front brake lever and all, and reap the benefits) its more fun being on the edge. ok don't try it, thats called cognitive dissonance. In this photo its the 50cc engine with 40t sprocket, now ive fitted a new 80cc black engine kit, today though I have to switch the front sprockets so I can use a...
 
This is our most recent acquisition, I got it from a local who sold it after barely getting it assembled, because they already had substantially the same bike already. I've finished making it safe to ride, tightened everything that was loose, and did some stuff like swap the seat out and slapped some Avid brakes on along with a dual pull lever. Also went ahead and deleted the big reed adapted snorkel intake because the whole thing made me sick, didn't clear my foot while pedaling, and wasn't...
 
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...
 
Is the new build this one will be much better am determined
Help needed for DIY engine Hello folks I am building my first 66 mL two-stroke engine I’m looking for some info on the crank case the question being would I be just as well off to go with a standard crank from eBay or go through arrow motorized bike for a balanced crank
 
Been working on this bike for a little while now put in a bent springer fork I didn’t want to cut threaded forks so I added some spacers and a shorter BMX stem really loLowered And I installed some really tall ape hangers I’ve been trying to strip off the old paint And been restoring small parts here and there Some engine work too but not ready for an install
 
Here is my latest build. It started life as a 1959 girls Huffy bike that my sister got new for Christmas that year. I slightly modified it, adding the springer fork, homemade tank, different rims and tires and of course the China girl power plant.
