Is this for real? Is that Andy on the bike? How fearless is this Photogrpher!!! Is that really you Presmou trusting that the biker will clear the jump.... I am too old for this...May God bless this new project...The creativity is very unique and breathtaking... Love, Panagiotasou....
I love the concept of the Quadricycle, but I would really like to see a Stretched Beach Cruiser bike frame as a Quad, maybe a Dyno Kustom Coaster/Kruiser Frame, could this be done, if someone bought your quad and redesigned it, or maybe you guys could b build one, as a non-sport, but Lowrider Luxury model, with a Ed "Big Daddy" Roth Shifter-style Lever & a Rat Fink Shifter knob?
:35 Look at the steering stem, where the inner tie rod ends attach. Now look at the pivots on the lower arms. The tie rod ends are as far apart as the frame is wide, not as far apart as the lower arms pivots are to each other. Cant really see the upper arms mounts in the picture, but they appear to be narrower than the lower arm pivots. This means the upper and lower arms and tie rods will all swing through arcs of a different radius. ie. bad geometry. Or maybe its really good and i suck.
you cant compare a road going cars suspension to an offroad car. with the amount of wheel travel present, things have to work a little differently. or the bump steer would quite literally kill you. Since the range of motion is much less in a road car, you can utilize the trickery of unequal length arms to keep the car turning the way you want. but alas, this is a quad that steers built using tires that are designed to lean. its all good, neat toy i spose.
Well, with cars in mind, if the upper and lower arms are the same size and squared to each other, then the problem is that when going around a turn the car sinks on the outside wheels, and the tire's contact patch is reduced. youtube "LPEpower episode 05" to see what I mean. The shorter top arm should minimize the reduced contact patch problem, but in fact, this bicycle utilizes round wheels... so the contact patch never changes anyhow..
is good for a ride,but not for race.little more stable in corners that a two wheels, but compared with two wheels bike is heavy and the aceleration is considerably lower.you need better relation power weight for be more faster.for me the 2whees is best.
Hahaha... Are you sure? it looks like the top and lower A are not the same size and the steering links might have the right proportions for this setup, but I don't know that much about car suspension! so what makes you say that? If you are correct then this is really very funny.

Conceptually, other than slippery roads, this thing has no advantage over conventional MTB ridden by normal cyclist. Craft is perhaps superb, but for such a narrow utility, it's not worth even consideration.
Hey Andy - It's Tony! This is AMAZING!!! Very proud of you bud!

This bike is crazy as hell i want one
holy bump steer batman. all this effort and to end up with front end geometry like that? snarf.

Sweet, I want one!!

Very nice! What does it weigh?
Over 9000
I'm guessing you're talking about the steering links angle, going from high up in the center of the chassis to down low at the wheel?
Muy bueno cuadriciclo donde consigo los planos para hacer uno
Where did they go!?
cool, I want it too.
i want one as well!!
How much?
I need this. And if I can't have it, can I have a copy of the blue print to hand make it myself? Where to buy?
Может в солидфорксе его проработать?Только в компановке не сидя, а полулёжа,заодно и центр тяжести сместится ниже и удлинится сам веломобиль!!!
faz um video mostrando o quadro do quadriciclo

I would like to get this bike. Due to car crash I have not enough balance to ride 2 wheel. Use trike now but would like to have this.
How does the steering work with tubular arms?

Andy, where can I buy one of these?
Why do you call U-joints CV joints? The above vid did not show the U-joint drivetrain in operation.
