New chainless e-bike berths

By Prince Osuagwu

Seen a bicycle that has no chain? That is a new born baby out of auto industry technology. Tagged, Mando Footloose, the e-bike is the world’s first chainless hybrid technology. Like other pedal-assisted electric bikes, the bike combines manual and electric power. It eliminates the chain and transforms the cyclist’s motion directly into electricity.

The chainless bike could produce solution to the age long complaints on chain bicycles. For instance, as integral as chain part  is to most bikes, it is arguably the most annoying component. It can dirty and rip your trouser legs, requires a lot of maintenance, can make your life miserable should it rub against the derailleur or slip off the gears, and can break altogether, leaving you without a means of pedalling on flat or ascending terrain. It’s a necessary evil, at best.

Footloose is a product of Korean auto suppliers Mando Corp. and Meister Inc. They partnered with British designer, Mark Sanders and Dutch e-bike expert Han Goes to make chain a little less necessary. The Footloose combines a throttle drive with pedal-assisted technology. Cyclists can power the bike up to 30 kilometers with the motor alone or pedal for more range.

What sets the bike apart from others is that pedal input is transformed directly into electricity via an alternator connected to the crank. The electricity is stored in a lithium-ion battery and used to power the motor. So instead of powering the rear wheel, the cyclist becomes a human generator powering the motor.

Similar to an automobile, the Footloose has an Electronic Control Unit (ECU), which works with sensors and an automatic gear changer to monitor terrain and adjust the motor’s output as necessary. The ECU also monitors the system for problems, which it displays via a handlebar-mounted Human Machine Interface (HMI). The HMI also displays metrics like distance travelled, speed and amount of electricity produced. It is removable and the bike will not start when it is removed, creating an integrated anti-theft feature.

Between its chainless construction and frame-integrated electronics, the Footloose folds up neatly for transport. It was designed with smooth edges to prevent any injury or discomfort when travelling.
