Iron Imperative
Motorbike has no handlebar, clutch or accelerator.
Inspiration from Nature
Daphnia Magna uses its appendages for multiple purposes including food-absorption and locomotion.

Problem Statement
Whoever thought of wheel for the first time was a wise person but today we say that there is no need to reinvent a wheel. Someone who craves for synergy in design might say that if wheel is not fully invented yet because its function remains to be limited. In a motorbike for instance, there is a handle bar, accelerator, brakes, gears and all kinds of navigational tools- to support a wheel. Let’s dwell on this point for a moment.
A cruise bike gives its rider a sense of freedom which is somewhat analogues to riding a stallion. Difference; one has to make full rotation of the arms to turn a bike. A stallion- pure muscle force which senses rider’s heartbeat- needs only a wrist movement. Riding a stallion is far more immersive than riding a mechanical cruise bike. And the key component which can abridge this gap is wheel. A wheel should be able to balance, accelerate, decelerate and turn with the command of a human mind. Design process of a (synergistic) wheel needs to be completed.
Nature Review
An organism was sought which used its locomotive parts for multiple purposes. The most suitable function was found in a common water flee called Daphnia. Appendages of Daphnia have little protrusions on them which allow them to navigate around while paddling. These tiny hairy protrusions also absorb edible particles in water. The strategy is the key to re-invent our wheel, one which does not need a mechanical handlebar or staring for navigation.
Technology Review
A number of wheels have been designed for various purposes. The latest invention by NASA is a chain wheel made up of nickel-titanium memory alloy wires. This technology is a huge milestone in production of self-navigating, self-accelerating wheel. Similarly, Honda’s self-balancing motorcycle and Micheline’s 3d printed tires are useful case studies in design of given wheel.

Nature Gadget
A motorbike tire is designed with pattern of extendable memory bristles (1, 4, 8) on its surface. Bristles control and distribute surface tension of the wheel (22, 23) causing it to accelerate or decelerate. The turns are made possible through elongation and hardening along either edge of the wheel. Each one of these bristles can store considerable amount of embedded tension (13, 14, 15). Every time it touches the ground it releases the tension backward (or forward for braking) so that the tire may accelerate or decelerate itself by a combined action of these bristles. There is no handlebar, only a fixed lead to control the bike.
