    i will be buying a camera of my own soon so i can take some more pics of this setup when im done

    its pretty odd but it does not slip when wet like metal drive friction drives :)

    I like it. Based totally in function and utility. Fits into no "style" but creates it's own. A reliable workhorse. Not meant to win any beauty competitions but will get you there without breaking down.


    I had a normal bicycle like this once, had so many bags and racks and places to store things it was crazy.

    yep its definitly purpose built and that purpose was to eliminate short drives with my gas hog of a thunderbird (highly modified tbird turbocoupe)

    and it does this well i have around 250 miles on the odometer already and have only broken one part on the bike and i didnt even notice it was broken until i made it home :) (just a 2 dollar clamp) time to fine better one's :shock:

    The drive wheel is a 10 inch tire with billet alu wheel 76 tooth rear sprocket size #25 chain 10 tooth front sprocket (the road gear since im in kansas) i have gotten it to 42mph on a long flat stretch the 6 tooth gear i have tops out around 25-30 but is much better on hills of course.

    one of the advantages to this engine is on the flywheel it has the the cooling fans like a lawnmower to keep the engine cooler than just wind alone. :) but its only rated at 2.5 horse mines probably around 2.7 with my slightly opened up exhaust. since this is a goped engine i can get loads of aftermarket parts for it as well tuned pipes all that jazz but 160 for a pipe seems harsh im more of a fabricator so one of these days :)

    i do however have a new project in the making im going to take one of these china motor kits (or maybe a small 4 stroke) and put it in a streched frame bananna seat bike from the 70's

    i found the bike next to a creek (on my parents land) lonnnnnggg ago and went back to where it was and it was still there it has some rust but nothing too bad and no the frame isnt streched already thats what i have to do :)

    it may be a long project this bike has the triple tubes on top for the frame one large tube where it should be across the top ,,,,,and 1 much smaller tube on each side of the frame about an inch away from it .

    this is one of those ones that had dirtbike number plackards on them with the cool bent out forks and mega far back bananna seat but the frame is very short length i will need to stretch it at least a foot for me to ride comfortably :???:

    Thank you very much.

    The simplicity of that wooden engine mounting is delightful.

    :shock: 42mph top speed and you were thinking about a tuned pipe...??!

    I like the idea of the wood as well... how does it hold up to the vibration etc?

    Dude... 42 MPH is quick!~
     
  12. Just when you think you have seen every possible way to motorize a bike. Man.
    The simplicity is amazing. Can you take another shot of that from the right side? Rubber to rubber yea. No slippage especially with also the tires having some give with the air pressures.
    BRAVO.
     
  13. Good idea. I like simplicity myself. What do you think about making this into a powered trailer? Make a long tongue that attaches to the seatpost. Get the weight off the bike & attach it only when you need an engine. Have you seen any powered trailer videos?

    If you built something like that using one of those Evo scooters, you would have a two speed friction drive.

  15. Poor GSR40....
    But you put it good use!
    I love GSR40 gopeds, I have 2...

    I wondered about the "wet" metal slipping spindle issue,
    I wondered if one tried to all a reinforced rubber hose over a spindle
    if it would eliminate the wet slipping as well.

    Probably not, I think its more about surface area than material. The knurled metal scrubber has a lot less material in contact with the wheel than the goped wheel in that pic.
