    So I finally got around to building a proper tank for my 49cc HT bike. It's built on an old non-suspension Stumpjumper. I'm still working the bugs out of it but had some major mounting issues with the stock tank (from the kit). I'm trying for an early motor bicycle look. Here are some pix of the tank. I'll be hanging the tank from straps over the top tube. Bike shots to follow.

    Nicely done. I am toying with something similar made from copper sheet. How much do you expet the tank will hold? Also how are you planning on mounting it? an't wait to see the finished bike

    Reminds me of the 1901 NSU from Germany.

    Or maybe the 1987 Werner from France

  7. It's amazing what a transformation a nice tank makes. Nice job. Putting some fat fenders on it will go a long way too.

    bikebum1975 - I thought originally of brass or copper sheet construction for the tank, then gagged on the price for just the materials! But ****, it would look cool. Good luck with your tank build and I'd love to see your bike. My tank holds about a gallon and a half. I've got welded tube through holes in the tank at three places . I've run a metal strap over the top tube in two spots and one behing the seat tube. I've got a through bolt with an acorn nut at each location.
    cgoodwin - I've got both those images (NSU & Werner) in my image files for reference. What I'd really like is if there were a 4-stroke bicycle engine built like those old 1901 type singles (de dion type) available instead of the little two stroke. I bet if one were available that looked like one of those old engines but with newer technology, they would take over the market.
    KeepOnKeepnOn - Thanks. I'm looking around for some fate fenders for my bike. The black ones from XYZ bikes.com for $4.95 seem almost too good to be true. Have you seen any good ones?
    bluegoatwoods - Thanks.

    As part of my business I build aluminum tanks, if there were a standard frame used I would make a standard tank, sadly there is not. I have considered making a tank like the early HD where a large rectangular tank sat over the frame tube, that would be fairly universal..

    4 stroke - I recently purchased a 4 stroke weed eater and a 4 stroke blower/vac at Home Depot, not a pretty motor though.

    Here is a boxer style 80cc motor.

    Some of the early Honda mo-peds were 4 stroke, like the 1977 Camino

    There might be a use for just a shorter rectangular tank that would hang under the top tube. It wouldn't have to go from head tube to seat tube. It would mostly offer an alternative to the peanut tank. Plus, there are alot of vintage examples that did that.
    A little more complicated would be an Indian-style tank that hung off the seat tube and wrapped over the back tire.
    Somewhat more universal would be a two piece tank or a one pice tank with a very deep yoke in the middle, that would drop onto either side of the top tube. The very deep ones would need some sort of crossover fuel line...

    The same friend who bought one of the HT kits and rides with me, just recently bought an old Maytag boxer 2-stroke. It was originally used for a washing machine. He is repurposing it for installation on an old skip tooth bicycle frame. I'll try to post some pix of it when it gets that far along.
    The old honda engines are nice but I am interested in finding something a bit more upright rather than the Honda 50-90-110 laydown engine.
    I've even thought of cobbling together my own motor, starting with a little briggs, completely fabbing a round crankcase and tall cylinder and lengthening the connecting rod. But that's a whole lot of work! I can dream, though.

    Looking at your photo again; are those the old "bio-pace" chainrings up front?

    It sounded like a pretty good idea when they came up with that. didn't seem to fly, though.

    I'll bet manufacturing costs were one problem.

    Yeah, good catch. When I pulled the bike out of the shed and cleaned it up to get ready for the motor install I never even noticed the bio-pace setup. Doh!

    I'll replace it with another non-biopace crankset but I was trying to figure out something that would look more 3 piece crankset look. So I was just leaving that way until I figured out something better. Just like the tank that I made to replace the peanut tank and the modified long-horn handlebars. My new hairpin seat is ordered as well as a set of fenders.

    Here's my friend's boardtrack style cruiser. I'm sure the initial reason he purchased the kit was that I had one and it would be something fun to do. But now I think that he really likes these little low speed forms of transportation.

    He's working on another bike right now which is an old skip-tooth frame and he's mounting a Maytag washer motor in it. I'll bet a lot of people don't know that once upon a time some Maytage washers came with a little two-stroke boxer twin engine. He's doin some pretty serious mods to the engine to narrow it enough to use on a bicycle. The frame has been lengthened 3" to be able to clear the length of the engine. I'll post some pix of this project soon.

    It's kind of funny that he like these very slow motorized bikes. Funny, because recently he set the world landspeed record at Bonneville for a 50cc motorcycle at 144.466mph. On that he' using a hopped up Aprilia 50 engine and it's turbocharged. 20+ hp at 14,500rpm amd 6psi of boost. I've attached a few shots of his record-setting streamliner.
