Students find promise in ‘Hubless Ryder'

Staff Reporter



Smooth ride: The team which developed a motorbike with centre-less wheels.

Thiruvananthapuram: Wheels are one of the prominent inventions of man. Though the inventor of this life-changing equipment remains unknown, many modern inventions have come into being from the wheel. As technology advances, the inventions take a new face. Hubless wheels, after their birth in the U.S. in 1989, have resurfaced here in the city in the form of the ‘Hubless Ryder.'

Shabin S, Asif Shereef, Abhijith Mohan, and Bibin Salim, final-year mechanical engineering students of P.A. Aziz College of Engineering and Technology, are jubilant after their success in creating a Hubless wheeled Enticer as part of their college project.

Typically, a Hubless wheel (also known as centre-less wheel or rim-rider) is one that has no centre hub. Promising safety, performance and reliability, these wheels had caught the attention of the biking world.

However, constraints such as high degree of precision machining and maintenance cost had discouraged their entry into the market. “No one in India had taken up this challenge till now for their college project. We wanted to create one which will provide high safety and efficiency similar to that of the ordinary bikes without the hub technology,” Asif Shereef, one of the brains behind the project, said.

The project, under the guidance of Professor Azeem Hafiz, was completed in four months.

The ‘Hubless Ryder' is built from a Yamaha Enticer, a cruise-category motorcycle with modifications on the wheel assembly, swing arm suspension and rear sprocket. The model uses chain-drive system and employs disc brakes. The model is said to have increased steering efficiency, providing a high degree of resistance during tilt. The makers say the use of disc brakes makes it more efficient as the grip can be located close to the ground where the forces act.

Honda, the motorcycle manufacturer, had showcased the hubless v4 model at the Intermot show in Germany in 2008.

Clearly, the hubless wheels have opened the doors for new developments with possibilities such as attaching electric motors to assist the rider, housing the entire propulsion system inside the wheel, and more.

The makers of the ‘Hubless Ryder' are confident that the future will see cost-efficient, elegant-looking Hubless motorbikes, taking technological growth one step higher.
