There are many vehicles to travel the cities, such as car, bus, taxis, etc. But, do you know more than a motorcycle? We can access it from any gap and does not generate parking problems. Yes, going on two wheels does not offer much security.

Although the bike is a fast and useful vehicle, its weakest point is instability. The deceased want to show the opposite, but although the positions and inclinations that the runners take on the curve are the same ones that can take the hares, the latter uses the four legs for it.

Theoretically, there is no balance over two points of contact in nature. At least three points are required to achieve stability. When bicycles and motorcycles are underway it seems that this law is not complied with, but if they stop, it is necessary to put the foot on the floor. In other words, there is dynamic, but not static balance.

With the aim of overcoming this stability problem, researchers have developed curious models. In this article, some of the characteristics of some of these models are shown. However, and analyzing the characteristics of these sophisticated models, it can be said that the problems have not been overcome, that is, what is gained in stability is lost to speed, comfort and vice versa. Therefore, fortunately or unfortunately, the bike will remain a bike.

Quasar quasar

Type: Type: Motorbike driving lying down. Squares: a length: 2,10 m wide: 0.90 m Weight: 300 kg Maximum inclination: –– Front suspension: swing arm, two shock absorbers Rear suspension: swing arm, two shock absorbers Front brake: 2 discs Rear brake: 1 Aerodynamic disc: complete; covered driver Engine: Honda 750, 4 cylinders and 4 times Displacement: 748 cm 3 Gearbox: mechanical and 5 speed Secondary transmission: Via carda Maximum power: –– Maximum speed: –– Price: If in England and 1.400.000 pts. Valid. General notes: Long-term driving justifies the assembly of a real body. Thus, two objectives are achieved: a more comfortable driving and a good protection against the face. To get a good driver position, the driving system is different from that of the classic bike. The latter uses the driving fork, but in this other one the oscillating arm is used. The turning handle at the end of this arm forms the pivot wheel. The union of the end of the arm to the wheel is obtained by a strong steering radius. As the driver is lying down, the centre of gravity drops a lot, so it cannot tilt the body to the sides, since the stability to take turns decreases. In general, it can be said that the entire system is unstable.

Oekomobill

Type: Type: Fully covered Number of places: 2 in tandem Length: 3,75 m Width: Between 1.27 and 1.40 m Weight: 320 kg Maximum inclination: 51° (the best motorcycles so far had a tilt angle of 50º) Previous suspension: telescopic fork Rear suspension: single shock absorber Front brake: double disc Rear brake: one disc Aerodynamics: a fully coated disc and fiberglass body, armed with Kevlar (less than Cx 0.2) Engine: BMW K 100, 4 cylinders, 4 stroke displacement: 987 cm 3 Gearbox: mechanical, 4 speed plus reverse Secondary transmission: Via carda Maximum power: 66 kW 8000 revolutions per minute Maximum speed: 250 km/h Price: If in Switzerland, 3,200,000 pts. Environmental value. General notes: When the bike is stopped, the driver can't pull the legs out, so two stabilizing wheels leave on the sides by order of the driver. The computer warns the pilot when the speed of the bike is less than 7 km/h. The bike is longer and wider than the classic, so it is not very comfortable to travel through the city. But its biggest problem lies in its poor stability. The driver cannot tilt the body so the stability loses a lot.

Amorton car

General notes: The author of this bike, Sanyo, has not published information and the only thing he wanted to do is try silicon solar cells.

Scooter wolkswagen

Type: tricycle Seats: 2 successively Length: 3,17 m Width: 1,49 m Weight: 550 kg Maximum inclination: not incline Previous suspension: McPherson Rear suspension: a single shock absorber Front brake: –– Rear brake: –– Engine: 4 cylinders of 4 times Displacement: 1050 or 1400 cm 3 Gearbox: mechanical; 4 speed plus reverse Secondary transmission: Via carda Maximum power: 29 kW or 66 kW Maximum speed: 160 or 220 km/h Price: not sold General notes: It is unknown if it is a purely commercial essay. We know little about stability. At the moment there are no entrepreneurs who accept this problem.

Moto crabe motorcycle crabe

Type: articulated tricycle Seats: 2 in tandem Length: 2,50 m Width: 1,05 m Weight: 320 kg Maximum inclination: 35º Front suspension: telescopic fork Rear suspension: two wheel dampers Front brake: one disc Rear brake: drum on each wheel Engine: Moto-Guzzi neighbor and 4 times Displacement: 850 cm 3 Gearbox: Mechanical Panhard, 4 Speed Backwards Secondary Transmission: Chain Maximum Power: 51 kW 6500 revolutions per minute Maximum speed: Price 160 km/h: not commercializable General notices: The union of the rear wheels by an articulated trapeze makes them tilt together with the bike, so the stability of the system is good.

Banana flying

Type: Type: Motorbike driving lying down Seats: 2 in tandem Length: 1,70 m Width: 0.60 m Weight: 160 kg of maximum inclination: – Front suspension: swing arm, 2 shock absorbers Rear suspension: swing arm, 2 shock absorbers Front brake: 2 discs Rear brake: 1 drum Aerodynamics: integral Motor: Honda 500 CX neighbor indrico of 4 times Displacement: 500 cm 3 Gearbox: 5 speed mechanical Secondary transmission: Via carda Maximum power: –– Maximum speed: –– Price: If you are in England and 520.000 ptas. Environmental value. General notes: What is said about quasar can also be repeated in this case.

Background gyro-up

Type: articulated tricycle Seats: 1 Length: 1,76 m Width: 1,10 m Weight: 94 kg Maximum inclination: 20º Previous suspension: Earless fork type Rear suspension: monomer Front brake: one drum Rear brake: one drum Engine: one cylinder and 4 stroke Displacement: 49 cm 3 Gearbox: automatic, by torque converter Secondary transmission: with belt Maximum power: 3,6 kW, 6500 revolutions per minute Maximum speed: 60 km/h Price: It is in Japan and 200,000 pts. Environmental value. General notes: Turning only inclines the front of this tricycle, but this inclination is not enough in some cases, so it may happen that one of the rear wheels rises.

Helix Helix

Type: Type: Motorbike driving lying down Seats: 2 in tandem Length: 1,70 m Width: 0.60 m Weight: 160 kg of maximum inclination: –– Previous suspension: Earless fork type Rear suspension: 1 shock absorber Front brake: 1 rear brake disc: 1 drum Engine: 1 cylinder, 4 stroke displacement: 244 cm 3 Gearbox: automatic per torque converter Secondary transmission: belt drive Maximum power: –– Maximum speed: 125 km/h Price: If you are in United States, 300,000 sts. Environmental value. General notes: The height of the floor to the seat is 65 cm, while on classic motorcycles is one meter. This is unstable, since in the curve the body cannot be too inclined.
