GL1800 Quad?

Post by WingAdmin »



Looks like rear trike and front trike kits grafted onto the same GL1800. What do you think of this?

Why bother? A total waste of a perfectly good GW1800.

Next they are adding a roof and doors? Oh wait, that's a car! ;)

+1 on what rambozo said. Might as well drive a convertible car.

I gotta say - that is one of the best looking Golf Carts I have ever seen. But he forgot his clubs.

Interesting concept but I think I'll stay with my 2 wheels. Somebody liked the idea and did it but I have a hard time even with trikes and the thought of riding them. No, that isn't a criticism of trikes, just my own personal taste.

As far as I am concerned, if you like it, ride it. Or in this case, drive it.

Ride Safe!

Now if it leaned, then maybe; only it doesn't.

Frankly, what a monstrosity!

And what's going on with that nose... Fugly!

WHY would you take a perfectly good bike, and ruin it in this manner?

I've seen better looking quad 1800 units than this one, by why? A trike or reverse trike would provide the same level of stability. Maybe they just wanted to stand out?

When the time comes that I'm not comfortable on two wheels it's a sidecar for me.

Nope, a wheel at each corner creates a more stable vehicle than three wheels given the same width (track) and length (wheelbase). It's just plain old physics.

True. A conventional trike is very unstable in decelerating turns. You know, when you're in an emergency situation, have to brake and swerve to avoid something, that's when the conventional trike will pitch you off.

A reverse trike is only unstable in accelerating turns, and the Can-Am Spyders all have stability control systems that will throttle the engine to reduce power if you approach those limits.

Very unstable you say? I've swerved AND braked morwe than once to miss things from dogs up to cars pulling out, never pitched off yet. Sure, if a co-rider is asleep and not holding on, can be pitched but then they could be likewise on that 4 wheeler.

It would have looked better as a trike, but that looks lousy, maybe confused do I want to be a Goldwing or a Civic. :o :shock: :lol:

I agree. The following is why non-tilting trikes are less stable than four wheeled vehicles:

Imagine a line drawn from the outer-most part of each tire's contact patch to the next. For a trike, this describes a triangle, for a four-wheeled vehicle, it describes a rectangle....


At a standstill, the centre of mass of the vehicle should rest somewhere along it's center-line. As soon as that center of mass shifts (through a combination of cornering, acceleration, or deceleration) outside of the light-blue area described in the image below, then the vehicle will topple!

You will see that the lateral (side-to-side) stability of the trike (red arrow) is roughly only half that of the four-wheeled vehicle (given the same track and wheel-base).

Trikes with two wheels at the front have greater stability to braking forces, than accelerating forces, and to steering inputs that cause rapid changes in direction. For trikes with two wheels at the back, the complete opposite is true. Most vehicles can brake an awful lot more quickly than they can accelerate. This combined with the fact we normally steer with the front wheel(s), means that a trike with two wheels at the front is far more dynamically stable than a more traditional trike.
So why don't we see more 'reverse' trikes on the road? Because they are more technically complex to build

Now if you can keep the center of mass of the vehicle/rider(s) well within the blue lines described above, the vehicle will not topple. This can be achieved by lowering the center of mass, or by dynamically shifting the center of mass to keep it centered... wait, isn't this exactly what we do when riding a motorcycle?

So the most stable trike would likely be a leaning trike, with two wheels at the front. Why don't we see more of these? ...Because they are even more technically complex to build than even a reverse trike!

Finally, if you are going to have a leaning trike, how do you achieve the lean? Should it be free-leaning, or powered lean? At this point matters become very complex indeed, and worthy of a whole different thread.
