    In this many years i have it with me, my bike suffered a lot of changes, this is a small gallery of his evolution.
    In the last ones there is no much changes, only some minors because there it's no much to modify.
    The last one (#7) , was taken yesterday.

    Hope you enjoy it.

    Hi David,
    My front wheel it's from a 110cc four stroke Chinese motorcycle, the one that are almost like a plague this times :p, i buy it from a motorcycle store, it was used, but for this purpose i dont have many requirements.
    The engines it's a standard 48cc 2 stroke, very old (and very problematic too!), with automatic clutch and rope start, i think u can find in the web a lot better kits than mine (i found it in a almost broke bicycle store, which has this motors for a long time and nobody was buy it).

    hey funker,
    thats definitely a funky setup, must have taken alot of work to get it like that, well done.
    the problematic side I can well relate to.

    I like it, thanks for the pics! The gas tank looks like it hold plenty of gas. Does the motorcycle muffler give you a performance boost?

  9. That fork. Did it slide in with the bearings or did it need a modify?
    The down side to that otherwise awesome setup is convinving the cops it's still a motoredbicycle and not a moped but I would be proud to own it.

    Hi skyl4rk, thank u for viewing :)
    The gas tank can hold (i think) no more than two liters, looks big but is not that much, it's long but thin, enough to make a nice trip :p
    Indeed the motorcycle muffler (really it's the entire exhaust system) works better than the original exhaust, have a good retain/release gas ratio, and make less noise and better sound. It's not a fast machine (more with the centrifugal clutch) but enjoyable.

    I have to make some small modifications to make the motorcycle wheel fit in a bicycle fork if it's that what are you asking for?. I had some concerns about the mechanical resistance of the fork, having in mind that a bicycle wheel weight no more than 2Kg and this motorcycle wheel weights more than 6!, but so far so good, no problems for now, even making jumps. :eek:

    Here there is no problems even with mopeds, no license or papers are required for engines with less than 50cc, the only time i was stopped by the police was because i passed a red light, but the real motive was that policeman whats to ask me about the engine :p.
    Thanks for your kind word, i m really proud of it ;) i have no sons for now, so this machine is my little "baby" :p

    You are a proud father then. What are the front forks from, if not motorcycle, BMX?
    Thanks for sharing.

    Hi Dockspa
    The forks are for BMX i guess, or what we call here "mountain bike", not an expensive fork (less than 30 u$s here, but because i think it's made in china). And it's almost undestructible.
    I have a front collision with a car than twisted my steel front wheel but the fork doesnt even have a scratch, nothing.

    Thanks you for watching :grin:

  15. Your bike has evolved nicely. I like how you have taken elements from mopeds, bicycles, and early motorcycles and combined them into a really sweet bike.

    Where did you find the small chainwheel? I've been looking for one about that size...very cool.

    Hey thanks Capitol , as you well said, my bike is "mix" of many worlds :p that, makes it funny, even girls love it ;)

    Talking about the chainwheel (i think you talk about the one connected to the pedals), it's from a moped transmission, 30 tooth, i arc welded them to the pedals ;)
    I put 415H chain in both sides, for motor transmission and for pedals, and are of the same length for "life saving" purposes in case of motor transmission broke down.
    My rear 38 tooth sprocket it from a moped too! My kit it does not even have a sprocket.
