the Dymotec S6 generator. Snowy stuff causes the contact between
drive wheel and tire to become intermittent, and the light goes
on and off as you ride.That little wire drive wheel worked like a charm!
I think constant use would probably wreck the tire sidewall in
short time though, even on a tire with a dedicated generator drive
strip along the edge.I recently replaced the worn-out (rubber) drivewheel on one
of my favourite generators with a Coke bottle cap.It works beautifully, even in rain. I guess since the
bottle cap is hollow & flexible, it conforms to the
contour of the tire nicely. I dunno how long it'll last.
But it'll be no sweat to replace it with another Coke
bottle cap. What's really notable is the lack of drag,
and the pleasant buzzing noise it makes.
That's an interesting adaption!
I've used grommets from the hardware store to replace the
rubber of drive wheels before. Worked OK although they
are slightly larger diameter changing the "gear ratio"
of the drive a bit.
But they still slip when wet. I'll check out the bottle
cap though. Seems it would be far more gentle to the
wheel than a wire roller.
