Motorized "Shaft Driven" Bicycles!

[Mike Lynch]

Might a Shaft Driven Bicycle of the type detailed on the WEB Site below be a candidate for motorization?

It's possible. There are several different shaft-drive bike makers (Dektra, Dynamic, Incline (Biria, WebBicycle).) Some caveats apply when trying to motorize them, however.

A happy time frame mount should work as-is. SBC's shifter kit, though, probably won't, without some engineering work, using the standard, rag-joint sprocket. Possibly, creative engineering's hub adapter could be used. All bets are off when it comes to the wider 4-stroke frame mounts, which typically need a wider crank.

As far as rack-mounts go, Staton's chain-drive system could be used, with some adaption. (the sprocket mount would have to be the same as a frame-mount, per above, but, you would want to add a freewheel at the gearbox)

Staton's, Dimension-Edge, BMP, and others' friction drives could be used as-is.

The GEBE system could be used as-is.

the old shaft drive unit has been seen around here before on bicycles
looks to be a good thing
although somewhere it is mentioned -- possibly not that strong ???
have owned some shaft drive motor cycles
liked them pretty well -- but noted -- they got some large shafts on those THINGS !!!
thinking that we will be seeing more of these used on bicycles
mentions somewhere about the ((clean factor)) something for some to be noted
my motor bike THING and I enjoy getting dirty
as we ride those THINGS

pretty cool.

Everything goes around... I have illustrations of shaft-driven bikes from the dawn of cycling, right around the turn of the century. Chain-drives were in their infancy, and the few available didn't work all that well. The simple shaft and bevel gears worked OK.
