Singlespeed & Fixed Gear - Two rims + One hub = threesome?

Got this weird idea yesterday that if you had say two 18h rims and one 36h hub you could lace it all up. Are two tires better than one? Another even more useless idea would be to combine two rims of different diameter with a wide fork. Even cooler you could dish them properly and put space between the tires.

I did once ride a bike that had two rear wheels crammed between the stays and a modified fork to accept two front wheels. It was stupid and fun.

I think your idea is even more stupid but probably also more fun. I say try it and see what happens.

three rims, one hub. why not

It would be a bummer if your center tire flatted whild riding :)

I wonder if all of the rims need to be dished accordingly or their side-side pressure keeps them true. That was kind of my next thought^ as cargo carrying capacity and traction are the only real uses of the extra rim. Could a 20" rim be built into/onto the same hub as a 700c (1/2 spokes wrap around and into 700c)?

P.S. Who built the bike above?

Why?
I would just ride on. 2 more left, hahahahahaha.

This is such a funny idea.

A Dutch bikebuilder, check the other pages. He's built some crazy ****!

hmmm....it's three rims, but they're not all attached to the hub. Maybe spoke calculation is too difficult and the truing would be insane.

2 girls + 1 cup yeah.....deeeeelish!

People have done it for snow or sand bikes for a while.
Then Surly came out with the Large Marge rim and the Endomorph 3.7" tire.

I guess that's a cassette and a derailer on the other side? To keep it out of sand and stuff? Pretty cool, never seen anything like that.

Two tires would seems like it would definitely be useful in the snow

But I gotta say, changing the tires or a flat would be a pain in the ass.

Wouldn't cornering be strange?

one would think... funny but stupid.

there's a word for three in back... training wheels.

I watched a guy with a bike like that pull his son in a trailer up Fargo Street (~32% grade) in LA. He had his Jack-shaft or transfer axle on a welded-on rack. With 50 tooth to 10 tooth gears on that shaft he had a 2" low. He built it as a sand bike. He was active in the IHPVA at the time.

I'm thinking this isn't a high speed situation.

Sneeuwpret!
