    Hey guys,
    I'm in the preliminary stage of building my first bike, so I thought in the meantime I'd entertain myself by asking for pictures of your awesome bikes :). I've already seen some cool stuff in my short time on this forum, but nowhere have I seen a thread devoted to pictures of your delicious machines!
    Let's see what you're riding :)!
    (also, if I missed a thread like this, please point me in the right direction.)‎

    bluegoatwoods Well-Known Member's mine. The frame is an old Huffy. Among the last that were made in Dayton OH. When I first realized that I could squeeze a happy time engine in there I was glad. I figured this would make a good motorized bicycle. And the answer is yes, to a point. It's good. But it has a few odd sizes to it and it's almost impossible to attach a few components properly. So this bike won't be around forever.

    It's the fourth one I've built since 2008. I'm recycling bike #3 right now into bike #5.

    I'll go off topic just a bit, too. The thread can surely get back to the point.

    Here's my wife's ride. A 50cc Honda Metropolitan.
    I never managed to convince her to love the bicycle the way I do. So I finally just bought her a scooter. She perked right up when I mentioned that, I can tell you. And she's been very enthusiastic about riding. She doesn't let the threat of rain, even cold rain, stop her.

    It's been great. I have a pickup truck and she has a Chevy Malibu. And now both of our 4 wheeled vehicles will sit for a week, 10 days, at a time without moving. Very economical.

    I'm even shopping around for new insurance that's willing to discount for very low mileage drivers.

    Insurance on the Honda, by the way. $85 a year. It might as well be free.

    Life is good.

    Nice build kgyrobotron!


    Is that a home made belt drive transfer case?
    What is your initial gear reduction with it?
    How does it attach?

    Front shock, rear disc, spiffy pipe, very nice.
    Don't just love what the little 4-stroke will do with gears?

    I am doing the same thing with my 10G long shaft transfer cases.
    Taking the output from the initial belt reduction and putting it out right above the pedals.



    Very well done bud.

    hey KC, thx, its just a lever belt clutch. A 1 5/8 pully to a 5" Js pully , with 11t to 60t #35 chain sbp freewheel setup. I've got 2200 miles on my lil 142. I've got the plug upgrade you sug. and an NT carb/adt. ..but it just fine as she is. I would like to a 70 or so big brother come out. The 53 just ain't big enough. I've got a Honda g100 I'm fixin. Flathead. And your bikes are always clean builds.

    I guess engine size depends on your state laws.
    Here it's 48cc and <20mph.

    Pfftt, these can double that speed and be close to that 48cc limit.
    I have been fighting for years to make that limit at least 66cc and 30MPH but Arizona is a wacky state.
    It's all more gun rights and abortion restrictions.

    I vote and never voted for any of them in office now.

    It's damn hard to grow a business when what you build is technically illegal to ride.

    This is my setup, with my next door neighbour contracted as the "B" prime-mover operator, to get the tonnage moving:

    The beauty of MB's is no license required, CA killed that concept.

    This is pretty close to legal here, just finished it up.

    I'm calling it the Emerald Jewel ;-}



    Good on or off-road.

    First post, I'd like to have that bike due to the dual suspension, where'd you gain such a cool frame?

    image.jpeg image.jpeg image.jpeg I've been building a lot of MB's.... Slowly getting to experiment with different power combos... Lol sorry bout the upside down pics, just the last few I've built.... Usually like to buy a fixer upper from people in my area and get it running to sell then the money I make off of it I use on my big builds (AKA, the silver bike...)

    Is that the gt5 frame? I've thought about looking into those

    I usually stick to older "rat rod" themes or something that I'm not afraid to get dirty or scratched... But don't get me wrong, I like to go fast, look cool, and make a lot of noise

    That is a GT-2A frame. I think sells one for about $120. This version has the curved downtube and it is not perfect.. The motor pedestal - if not supported - will fail. The thread less headset is not the best for a motored application. Over time, the AL frame will crack - somewhere. I'd consider it to have a 18 month to 2 year lifespan.

    It does look good! 26" wheels are perfect! One piece crank is cool. I like 1.75" rear tire. Fat tires won't work on this frame.
