my mountain bike soon to be motorized

[paul]

this is my pride and joy. i spent a few years building it from a schwinn home grown frame. the paint is all custom airbrushed and most all the parts are carbon and titanium. could have bought a car for what i put into this bike but i love it and use it to play in the woods. it weighs in at less then 20 lbs or less then 9 kilograms which i have never seen a mountain bike with full suspension this light

Cool looking bike but....."Where's the Motor?"

I wish i could figure out a way to motorize it. would have to change the wheels and stuff and that is all part of design. i figure i need some exercise once in a while so i will leave this one for pedal power

You could try a rack mount....I hear Jenna's lonely ;-)

PS - love the bike!

how would i put a sprocket or anything else on the carbon wheel?

Hmmm....Good question....short of a custom adapter, is your hub set up to use the standard ISO mounting for a disc brake?....If so, the sprocket can be mounted in place of the disc.....I was experimenting with this as an alternative to the HD 9 hole mounting system because some people were complaining of spoke breakage and also, by mounting the sprocket where the brake disc would normally go it would make for a very accurate /
precise mount (no more run out or wobble)....Of course the disc normally does sit a little further outboard and this may cause a minor alignment issue on some bikes (not all but possibly some)....Another benefit of a direct mount would also be that the sprocket could be changed out a lot more quickly.....I realize that Grubee makes / imports a hub for such a situation (direct mount of a sprocket to the hub) but I believe that their hub is more expensive than many disc brake hubs and is also not as good in quality form posts I have read. Hope this helps.

i went for total lightness. the wheels where available for disk brakes but added weight so i went for the lighter version. spin the type of wheel on their went out of buisness. kinda a classic thing and the darn wheels cost more then nice wheels for a car lol.

Wow...sweet little bike and I love the Spin wheels! Maybe you could rack mount it?

Very carefully.

Muy exotico!

I think that is going to have to be a GEBE type engine unless you can find a way of hanging a chengine off the front of the frame and chaining it to the rear wheel...

The problem with the GEBE set up as you have the bike will be wheels - they pretty much have to be spoked standard types or nothing - Trying to shoehorn a GEBE sheave onto those wheels would be pretty hard and is more likely to cause the wheel to fail mid ride..

I do have one thought however and that is using a roller type transmission rack mount either rear or front mounted or (and this is alot more complicated) using a chain fixed to the rim in some way meshing to a toothed gear off an automatic clutch direct from a mounted engine (similar to the cyclemaster idea)- but that would be a custom self-fabbed job and not for the faint hearted.

The problem with all rollers is that of slip - if its wet you loose speed unless you have the springs set very tight - but if you do that you get a bad case of fried and worn tires when its dry unless they are adjustable.

The belt drive is probably the most efficient and is fit and forget pretty much but it will need the spoked wheels (on the upside, if you choose that you can get a rear wheel set and trued with the sheave from GEBE for a reasonable price).

I love the style of the bike though but I do worry about strength a little - vibration can take its toll.. and it would be a shame if something terminal happened.. not to mention what might happen to it in a crash
