Tall Bike: 4-1/2 frames, 6 wheels, friction drive

Got this off a bike blog. One comment noted the rider braced himself at stops by grabbing hold of the overhead signal lights. Clever use of friction drive.

I wonder what his dismount record is like?



Amazing sight.

No helmet, no parachute, no ladder but plenty of balls.

I can't recall many six-wheeled bikes where five were drive wheels powered by one rider.

If it is friction drive, the chain will only run to the top rear wheel, which will then turn the rest of the wheels down to the final drive wheel.

Sorry, I've got no other pics. It is hard to see detail, now that you mention it. I can see a chain wheel at the top frame but I don't see the chain or rear sprocket. I see another chain wheel at the bottom frame and what looks like a chain and rear sprocket but no connection with the rider's pedals topside. I also spy what looks like a seventh wheel: small, white and on left side - it may be a stabilizer, sort of a single trainer wheel. How does this thing get pedaled? Maybe it just coasts?

It looks like there might be a chain running down the left hand side like on a tandem, and another chain to the rear wheel on the bottom right hand side.

I think there is a chain running down to that crankset in the middle, and then a chain running from the left of that to the left hand side of the crankset at the bottom, which then drives the bottom wheel on the right. So all the friction stuff is really just for show... Oh well.
