But 4 wheel bikes appear more stable than 3 wheeled one. I think this is just an amateur's design quad bike and out of weird designs may emanate something of invention value.
The notion of stability being used here applies to the bike sitting still or crawling along. While that may have some applications i.e. a vehicle for seniors, a 2 wheel bike is the most stable because the bike and rider remain perpendicular to lateral forces through turns while a 3 or 4 wheel vehicle will tip on a high speed turn unless it can be forced up on it's inside 2 wheels.
The gyroscopic effect of a two wheel bike standing still disappears (and it falls sideways). On a 4 wheeled quad, this aint necessary since it is always stable whether or not in motion. A 3 wheeled 'bike' is more likely to topple over in high speed turns than a (rectangular arranged) quad wheels 'bike'. Also a 2 wheeled bike may slide-topple' sideways in slippery surfaces during high speed turns.
A quad. wheeled 'bike' is more stable than a 3 or 2 wheeled bike in down sloping turns (since it has both front and rear wheels separated apart from its counterpart, giving it a lower center of gravity and stability). In other words a 4 wheeled 'bike' is safer than a 2 wheeled or even a 3 wheeled one (though more effort needed to pedal since it might be heavier).
A 3 wheeled bike can be very stable if it has a low seat for the rider. I have a trike that has a low seating, and I can take turns quickly without tipping issues.
Please show us more details. With gas prices going up, we may all be on bikes soon. This home-built one is absolutely awesome and highly functional. We'd all love to learn more about it.
What about adding something to make it faster? Like a fly wheel forward thrust and then a pin device to shoot if even faster?

Have you considered using a Granny Bike Conversion kit which is also a 4 wheeled bike and very stable and cheap to make?

If you made a roof for it, you'd be riding in the shade, while other cyclists around you would be sweatin' in the sun.

Y 4 instead of 2 or 3?

because 3 wheeled bike looks like kids bike.

4th wheel = extra weight, friction, inertia, cost, and engineering no apparent advantage.
The steering system is horrendous. The basic recumbent trike is already in production.

IDIOT!! The real funny is build the shiit. Not buy one on e-bay.
The sterring really must change

front wheels need to be farther apart to be more stable on turns.

im making one that you sit like a normal bike but it has 4 wheels
eliankou 4 years ago
so how many gears and how fast can it go.
the nice thing about this is that you could enclose it and put the seat back and sleep in it and go cross country.

I like that idea, kool! I have a 3-wheeled bike with a tiny car body on it.
