    Default Plans for a 2 speed dog clutch gearbox

    Alright do-it Yourselfer's...After saying I don't have time to build you one a million times...I took the time to draw up a simple 2 speed Hi-Low range gear box. small enough to fit a frame & tough enough to hammer on.

    Originaly designed to use with a tiny electric motor, I have upgraded the prototype & regularly push 3 hp through it. Aproaching a year of mostly off-road abuse without a glitch.

    here are a couple photos of the unit.
    on the bike..(its there)




    Any way, there it is if any one wants to scale it to fit their application
    reduction is 1.86-1 in low & 1.1-1 in high.
    Hope to see some built by the do-ers around. Thanks for looking & good Luck!
