    Hello everyone, i just joined the forum, interested to see what goes down here, i see lots of interesting subjects being raised concerning bikes and i do believe that there is probably a lot of info which will save me a lot of headaches,, i am still in the process of researching this topic on the internet, i realised i want to build a bike which can incorporate old school style with modern go-fast goodies and be comfortable to ride.
    So far, getting the correct balance of looks and comfort has made me cut this bike 3 times already,,,by trial and error, it still needs further experimentation (ride angle, crankhub positioning, how low is too low,etc).
    I expect to achieve 100k/ph with what i have planned.
    I am trying to attach pictures,,
    cheers

    Really cool design! I have a stretched out cruiser that i added the rear suspension to. I was considering putting a motor on it. The challenges I'm seeing is a self adjusting chain tentioner. Did you already that figure that out? Make one with a spring?

    Welcome and thx for those photos. You weld up a cool bike :)

    I dunno about hitting 100KPH on a bike, though. If you really need to go that fast a motorcycle is advisable. No part of a bike is ment to ever go anywhere near that fast and they have a bad habit of self dissassembeling themselves at those speeds. Wear lots of body armor if you do, though. Huge raspberries hurt like he.ll and will ugly your face in a hurry..bf.

    Hey Rebel, thats exactly what i have been investigating lately, i will need to machine up a slotted plate-spring tensioner which will probably be situated on the jackshaft although i will have to bench test its efficiency in real world terms, just need to get all the angles right first before i start butchering things up again, the morini i am putting on this thing has got some grunt, so i wont be rushing this build.
    i have been planning on building this beast for years,, its gonna have that morphed-custom world war 2 look about it,, i am still sourcing parts,ie- guards, lights 4 litre custom tank, some sheet metal infil etc,, jeez i am excited just typing this,,
    cheers
    C,K.

    Welcome to the forum, Good looking bike you got started there. Lucky you to have the tools and materials available. Think i'll stick kits and just upgrade to a better kit each time Im ready throw another one together.

    Thanks joe, it helps when you are a fabricator /blacksmith by trade,, messing with pushbike frames is just like a walk in the park with all the forming /forging tools, welders, etc i got on hand,, i am doing this bike as a sort of stress relief/ toy.

    Nice frame and good ideas. I've got a Staton system on my bike. Certainly build your bike according to the terrain you'll predominantly be riding on. Where I live there's a lot of steep hills and long grades. So the need for my engine to drive multiple gears was a must. On my bike I manually shift the front three gears and the rear seven shift automatically. I use a crank drive system. The downhill gear I've reached speeds of 45 mph (72 kph).

    use a rear derailer for a tensioner , but there are others out there or you could fab up one your self.

    derailler for a tensioner sounds good, although the best part about coil spring suspension is the fact i can adjust it to be super hard at the back or soft just by turning the threaded end cap, which by doing so will stop any chain slack, but inturn is a much harsher ride,,, i borrowed 2 from a huffy mountain bike forthe front and back of this bike, when time comes for motor and road testing i am glad i have the option of adjustment,,, still not sure about the springer forks i fabbed up on the bike, i have a set of full length internal spring forks from a shwinn mountain bike which i may add a springer style arrangement to later, they feel much softer than the ones i made, the springerdance1 addition to those forks will allow fine tune and adjustment for the front, if i make that decision i will have to cut the frame again to fit,, oh well,, its fun experimenting with stuff you enjoy twice.

    amen , Crankit, check out mine its a similar build only difference is I use a rokshok, air pressure at 125 , an it has adjustable bound an rebound a neat feature of that shock is you can lock out its movement if you want ,reallllllllllly smooth ride . check out my build mock up kinda rough an you can see the rear derailer acts as a chain tensioner .
