Worlds highest gear?

This bike comes with a 300 tooth chainring, pretty impressive!

It's intended for those who have stupidly large quads.

you'd think that ring would cost the £299 asking price alone

impressive spec

Talking of silly gearing, do they still do those roller speed record competitions? I seem to recall specially made bikes with 2 chains that had 400" gears or summat stoopid like that.

I think the bike that Dave LeGrys used to break the world roller record had double-reduction gearing - otherwise the chainrings would have hit the ground, likewise the one that was used by John Howard to break the absolute speed record that was towed behind a car to about 70mph, because you physically couldn't accommodate the gear range to reach 152mph from a standing start.

That's the fella. I remember seeing DLG being towed behind a faired Rover SD1 and doing about 130mph on the M forty something back in the eighties. I think the roller racing now has to be done on standard bikes and the record was done by some German (?) fella who was pedalling at about 250rpm!

edit: found a vid.

Wasn't it with the DLG record attempt they were hampered by the fact that the Rover just couldn't go fast enough with the fairing on the back? I suppose, seeing as it was a 1980's Rover they were lucky that it went anywhere at all!
