• Front Suspension: MacPherson

We have utilized the MacPherson Struts, the most popular concept in the automotive industry to provide low-profile shock absorbers with high rideability. The shocks are not too soft to lose the rideability. Soft suspensions cause separation of the tire from the ground because of high-amplitude road vibrations. Yet, they are not too hard to impede a smooth comfortable ride. In MacPherson suspension systems, the shock absorber and coil spring are located in one unit.

• Rear Suspension: Pneumatic

Unlike most scooters in the market, we accommodated suspension system for the rear wheel to provide a great ride comfort. This requires an effective engineering design to avoid any waste of traction energy in form of squat effect. We utilized Pneumatic Struts/Shock Absorbers to reduce the size and weight of struts by merging the spring and damper in form of pressurized gas. In short, there is a sweet spot in suspension design between soft and hard that makes it most effective in response to road oscillations.

What is squat effect? In vehicle dynamics, there is always compression effect in the suspension systems which wastes the vehicle traction in form of compression in the struts. We have minimized the squat effect in CYRO by our combined suspension system.

• Safety is always number one priority in our designs. Stopping the vehicle in a short distance has always been a challenge in automotive engineering.

• To achieve an excellent braking experience, we integrated 3 different braking systems into the vehicle:

1. Front Wheel Mechanical Brake:

   We used widest disc possible within available wheel space to increase the contact area of the caliper and disc. This helps to maximize the friction force between caliper and disc.

2. Rear Wheel Mechanical Brake

   In vehicle dynamics, it is always dangerous to rely on only one brake, specially on front wheel, the reason is that most percentage of weight is transferred to front wheel in braking process. This causes high chance of vehicle rotation in pitch axis and therefore losing balance. We have added the rear brake to distribute the brake forces on both wheels and reduce the chance of pitching by allowing the driver to adjust the proportion of the brake forces on front and rear wheels.

3. Rear Wheel Electronic Regenerative Brake

   Energy is an asset and hard to attain. In Hybrid and Electric vehicles, utilizing the electric power efficiently is a challenge. To restore portion of electricity power used for traction, we used Regenerative Motors to save portion of braking force in form of electricity. The Regenerative Motors are able to work like an electric generator to convert the wheel rotational energy into electrical energy. We restore this generated electrical energy in the battery any time you apply the brakes so you can use it again while accelerating.

• Tire dynamics is one of the most challenging topics in vehicle system dynamics given complex non-linear forces. This makes it difficult to simulate and design a perfect model that is efficient in producing high lateral and friction forces.

• Width: 2.5 in (6.5 cm)

  We used our pure automotive engineering experience to come up with an effective tire design. We avoided thin tires which may cause mechanical strength weakness in road bumps, we also avoided an extra wide wheel that is unnecessary and does not help with increasing the friction force of the tire on road pavement.

• Diameter: 10 in (25 cm)

  Wheel and tire diameter plays a big role in efficiency of vehicle traction and interface to the road condition. When the wheel is larger in diameter, it helps in facing road severe bumps. It also helps the vehicle pass the bump and avoid falling in the potholes and causing accidents. It also helps reaching higher speed. However a larger wheel has its own downside. It reduces the vehicle acceleration and increases the weight of the wheel which is eventually extra costly on material and spending energy.

• The key to increase safety is to see and let others see you! By developing bright LEDs covering wide angle around the driver, we could design a lighting system which makes your ride safer and more pleasant.
