Triangle wheeled bike - Burning Man 2012

Note that, while the wheels appear to bounce, the frame and rider don't bounce a millimeter. The wheels are in the shape of a Reuleaux triangle - a curve of constant width. The frame sits on top of the wheels, supported by rollers within the fenders.

This is a thing of beauty! Thank you for making and sharing. I had previously discussed with a friend of mine that Reuleaux triangles, while being impressive for their constant-width properties, were totally useless for application as a wheel because they have no point in their interior which maintains a constant altitude. But I'm delighted to see you've proved us wrong! Very clever your articulating fork ends and the horizontal sliders to support the bike frame upon the constant width of the wheels. How did you minimize friction?

[@hunterdolgener5634]

Canadian wheels...

[@woowoobars3792]

The suspension is the only reason that thing is ridable.

[@joebob9748]

Merritt it's not suspension that makes it stable. Since they always have a constant width, the wheels run against the fenders of the bike help keep it at a constant height. The things that look like suspension are just there to allow steering and the wheels to go up and down

I'm less impressed by the wheels themselves, than the system used to adjust for the ever changing centers.

[@test5093]

There is no system, the frame is resting on the tops of the wheels at all times. The center of the wheels are simply attached to springs so they are free to move up amd down.

[@gamerGUY3013]

I'm more impressed with the system used to steer the ever triangular wheeled bike

[@quinnharris3283]

@@test5093 You just described the system.

[@johnassal5838]

@@quinnharris3283 Not really, it's just a really soft suspension with a lot of play that would still absolutely kill you on any surface rougher than that flat playa. I was expecting an eccentric offset at the hub of each wheel which would maintain a constant radius and result in a much quieter bike you could ride on rough ground without needing a proctologist.

[@anandixitin]

Don't see the need for shock absorbers. Thats the uniqueness of the mechanism. But there is a need for holding the triangular 'wheel' in its position.

[@Thatslikefortoddles3789]

​@@anandixitin without the shocks the whole front half of the bike would jump up and down

[@N.Nocturne]

@@Thatslikefortoddles3789 it is not a "shock absorber" per se. It holds the wheel so it is free to move on its vertical axis, but a spring isn't necessarily needed.

[@KXSocialChannel]

In order to offset the wheel shape change, I suggest swapping the triangle seat to a circular one.

If you have no intention of going fast or having a smooth ride, this is the bike for you.

[@phillipmiller7168]

There are ball bearing rollers withing the "fenders", allowing relative motion between the top of the wheels and the frame. However, the relatively small radius at the points of the wheels (which contact both the rollers and the ground each revolution) results in an irreducible level of friction.

[@pexfmezccle]

replace the rollers with a conveyor belt

[@Robot831]

U got a shout out by a 2.3 million KZbinr

[@psnKnowledge]

@@Robot831 Couldn't they improve the design by making actuators/rotaries be based around a unibody flat seat rested frame without the use of any rollers or a second friction point for the wheels.

[@llm3935]

Add more sides to the wheels ! You'll come to the conclusion that circles are the best :))

[@theZakasol]

add more wheels to the side. youll come to the conclusion a true master is always training.

[@theexpendable5307]

circles only have two sides, an outside and an inside XD

[@V0YAG3R]

qpae123 no

[@qdaniele97]

Circles are better only because they can work with a fixed axis

[@comodore3684]

@@qdaniele97 and because the friction between the wheel and the ground is always minimum in a single point - so less friction - more easy unlike these triangle wheels which seems to require a lot more force because of friction the fact that triangle rotating are kind of irregular when the wheel is just before a 'point' of the wheel (3 angles forming like a pic) and maybe the coordination of the two wheels (when the ground contact of one wheel is for instance between 2 angles and the other too)

Yea, it doesn't bounce because the shocks are moving up and down, which absorb it. Plus over time a little thing called friction will turn these into a circular shape more famously known as the wheel we have today. Good lord.
