Engineering

Whether they want to go straight, turn, decelerate, or reverse, the rider has complete control of anything they want to do through the handlebars.

With RiDE, all riding functionality is available at the handlebars. It is designed to provide core operation through the levers and steering. In the pursuit of craft-focused riding for fun, we aspired to provide intuitive handling and ease of use.

Deceleration functionality for comfortable riding

With RiDE, deceleration occurs by deflecting the jet thrust forward using the reverse gate.
This deflected jet thrust is split into left/right directions.

Discharging the jet thrust upwards and downwards was also thought of during development, but proved to be problematic for providing stable deceleration.
To solve this problem, the jet thrust is discharged in a sideways direction, left and right.

How stable deceleration is achieved

By having the jet thrust move sideways left and right, there is less rotational force around the center of gravity of the craft, allowing more placid behavior.
This allows good posture when decelerating, giving a sense of stability.
However, discharging the jet thrust up and down creates greater rotational force around the craft's center of gravity, causing a nosedive where the bow dips downwards.

When the jet is directed sideways
When the jet is directed sideways

As the distance between the vector of the jet thrust during deceleration and the center of gravity is short, the moment around the center of gravity is small. There is thus minimal changes to the craft's posture, making it easier to maintain a stable posture.

When the jet is directed vertically
When the jet is directed vertically

As the distance between the vector of the jet thrust during deceleration and the center of gravity is long, the moment around the center of gravity is large. This is likely to lift the stern, in turn causing a nosedive.

Enabling steering operation even when reducing speed

When the jet is directed sideways, a difference in the amount of jet thrust between the left and right side will occur when the jet nozzle direction is changed via steering operation. This difference in jet thrust enables steering even when reducing speed. Adjusting the jet thrust in order to make a turn is difficult when the thrust is directed vertically.

By optimizing the shape of the reverse gate, the difference between left and right jet thrust can be adjusted via steering, thus enabling the rider to turn even when reducing speed.

Instrument display that is easy to grasp

We have paid great attention to the instrument display design as we believe that understanding the current shift position accurately is necessary for creating intuitive handling. The instruments can be recognized in an instant, even while the rider is on the go.
