World's Lightest and Most Compact Electric Bike Can Fold Into a Backpack

Business

Folding bikes are already incredibly convenient, but throw in a battery and an electric motor, and now it's a bike commuter's dream. At 26 pounds, the A-Bike Electric claims to be the lightest and most compact e-bike in world.

With its tiny wheels and a battery that's the size of a thermos, the ride is so small it can tuck inside a backpack or under a desk, making it a cinch to take onto a subway, train or car. Parking isn't even an issue when you can easily take it inside of a store or restaurant.

"It's the perfect ingredient for mixed-mode transportation," A-Bike Electric designer Alex Kalogroulis told Fast Company. "Bike-train-bike would be a typical new commuter scenario."

UK inventor Sir Clive Sinclair came up with the original concept of the lightweight, folding A-shaped bike back in 2006. Unlike typical bikes, the A-Bike has a fully enclosed chain system, which means that once it's folded the chain won't get caught onto anything, and your hands or clothes won't get dirty from grime.

"The idea is that if you have a bicycle which is seriously lighter and more compact than anything existing at the moment, it will change the way in which people see bikes," Sinclair said about his invention.

With lazy commuters in mind, this updated version simply adds a motor in the front wheel and a 24V battery. Although it's small and light, the e-bike is made with aircraft grade aluminum and high-strength glass-reinforced polymers. The designers also claim that the bike can fold in 10 seconds.

"Folding e-bikes typically weigh in excess of 40 pounds," Kalogroulis told Fast Company. "As the original A-Bike weighed less than 13 pounds, there was a strong reason to add a lightweight electric system and offer a unique combination of a lightweight electric and compact folding bike."

And if you're wondering about those dinky wheels, they seem to pack more power than one might think. "The dual chain drive has been optimized so that the rate of pedaling matches the rate the wheels turn, this makes riding A-Bike Electric feel like riding any other bike," the designers wrote on their successful Kickstarter page.

The bikes have a projected retail price of $1,089 once it hits stores or you can preorder it on Kickstarter. Check out their campaign video below to see the bike in action.

Back in April last year, the Trump administration's Environmental Protection Agency decided it was "not necessary" to update the rules for toxic waste from oil and gas wells. Torrents of wastewater flow daily from the nation's 1.5 million active oil and gas wells and the agency's own research has warned it may pose risks to the country's drinking water supplies.
