    New scratch build, need some info

    I have acquired all of the major parts to start my build, and now need some info about frames sizes. My goal is to essentially clone a 70-74" Rupp bike with the motor cycle style frame, but the problem is I have no sample available for me to examine. Although it won't be a carbon copy, I would...

    Cost effective / Good idea to build GX200 from scratch?

    I'm thinking for the future on my Rupp that a GX200 would probably be the best setup. Its already got a GC160 which runs fine for now but I don't think it will hold up to much use with the aluminum bore. I been watching craigslist but not seeing any good deals. I noticed that they sell bare...

    Utility Bike from Scratch

    Im building a Utility bike from scratch using a 5hp honda gc160 and torque converter. The tubing is all 1.25" mostly from a couple pressure washer frames. The frame will be rather intresting. The giant swingarm will hold the engine and everything and there will be a tray above the back wheel to...

    VESPA Scooter Scratch built by Jeep2003

    This bike will be a scooter looking like an old Vespa but smaller. Im using 4" wheels from an Arco. The engine is an old 2 stroke Tecumseh I think from a little snowblower. It runs good and seems powerful enough. I filed down the shaft to fit the 5/8" clutch. The old one was small with a big...

    Another Scratch Build by Jeep2003

    Time for a new progect so I puled out this frame I built a few years ago when I first got my bender. Im using a beauitiful old original 1964 Briggs. Its a tight squeeze on the air filter I might have to spread the frame a hair to keep from wearing on the paint. But im going with a 6" manco in...

    My First Mini Bike Project

    The pics are a few shots along the way during my build. I fabricated everything at home and used a Honda GX160 from a pressure washer that blew the pump. Engine runs great. The bike is a real cruiser and a lot of fun to ride.:thumbsup:

    First Scratch Built Bike

    Hi all, We have taken up the task of making our own mini bike from scratch. We purchased a bench mounted pipe bender the other week. I liked the look of the Taco Frijole so we decided to bend one up. It's our first attempt at making a bike so it won't be perfect, and we will run into issues but...

    For the safety of your kid.....

    Here is an example of what you do for your child when he's full throttle heading for the catch fence....... You take a wheel, a tire and fender into the calf muscle ! And he didn't get a scratch

    Gramps mini bike build

    I'm building a mini bike from scratch plus Azusa frameless 8" kit and Predator 212 engine. I've tried to read as much as I could before and during the build. Why is it so difficult to find some basic dimensions like wheel spacing, inside frame minimums, etc.? So far I've been working on it for...
