Anybody Make Front Wheel Drive?

[augidog]

well...let's pretend we believe we can do anything...you'd have to look closely, is there physical room to install the gebe drivering? no? if ya still wanna do it, you'll have to go looking for a fork, i'm sure it exists. prolly a downhiller fork. yes it does fit? ok, good, what's next? can we get it to ride with the suspension? the answer to that one IS yes, but you'll have to do that believing thing again. consider swapping the v-brakes for a sturmey-archer drum, grind the v-brake "studs" off, use the cross-bracket for the mount "anchoring" strap.

you want it to work? then make it work

me? i believe i can put 2 factory-matched gebe-drivetrains on the same bike. dare me, & i'll put 3 on a trike.

For those interested, I made some measurements of the GEBE drive wheel and rear bicycle wheel joined together.

Frame Clearance:
Utilizing rear wheel mount (or front wheel), the GEBE drive wheel sticks out 1.25 inches from the center line (of the wheel) towards its outer edge (which is to the left). That means your fork or your rear frame must have a little more than 1.25" of clearance from dead center to the fork or frame, so that there is no rubbing of the drive wheel against the frame or fork. More is better.


I made another measurement:
The GEBE drive wheel, when mounted on to a 36 spoke, 26" wheel, the distance from the wheel's inside surface (where the spokes come out) to the outer edge of the GEBE drive wheel is 2.5 inches. This measurement is important, because you have to go 2.5 inches down and measure the frame clearance from there.

Using spacers, I was able to achieve adequate clearance on my project bike (see pic gallery).

Side note: It's preferable to switch to 5/8" nutted axles to support the engine mount brackets. Quick-release axles may or may not have enough length to accomodate the engine mount brackets; plus, they're skinny compared to 5/8".

Suspension Forks: Rock Shocks/Manitou's

Will the GeBe front-wheel mount work with a mountain bike that has a shock fork and V brakes? I would assume it wouldn't work with the shocks, but I thought I'd ask.

Robert, it will work if your fork will clear the drive wheel. Take a measurement from your wheel's centerline (where the spokes come out of the rim), to the inside surface of your left fork. If you have over 1 1/4" of clearance, it can be done.

You also should have the nutted axle instead of the quick-release. GEBE sells a pair of nutted axles.
