An electrically assisted bicycle that can recharge even going uphill

J-STORIES - In 2022, almost three decades after the world’s first electrically assisted bicycles appeared in Japan, sales reached 795,000 units, for the first time pulling ahead of ordinary bicycles. Sales are also booming in Europe and other parts of the world, as consumers see electric bicycles as a healthy alternative to cars and a way to help decarbonize society. It has been estimated that the electric bicycle market will reach $73.2 billion by 2030.

A recent addition to the electric bicycle peloton in Japan is the Mag Drive System Smart E-bike, developed by Hello Space, a startup from Kumamoto City on Japan’s southern island of Kyushu.

Its unique design includes magnets that boost pedal power at the same time as the bicycle recharges its battery. In “eco mode,” it is possible to ride the bicycle indefinitely without connecting it to an external power source, and the only limit is the usage lifetime of the battery. Electricity stored in the battery can even be used as an emergency power source.

Electric bicycles and electric vehicles (EVs) contain expensive batteries that account for much of their production cost. Additionally, the time needed for recharging and lack of charging stations have hindered their popularity.

Conventional electric bicycles typically convert kinetic energy to electrical energy as they decelerate, returning it to the battery for reuse. The amount of electricity produced this way, however, is low, and batteries are typically not fully recharged.

By comparison, Hello Space’s Mag Drive generates electricity not only during deceleration, but also acceleration, making it much more efficient. Its “superconducting” technology keeps magnetic and electrical resistance to a minimum, meaning batteries last longer without running out, and charging is possible even when cycling uphill.

“The balance between electricity generated and consumed is key,” says Hello Space CEO Taketoshi Iwashita.

He says that going uphill electric bikes use more electricity, but on the flats they typically generate more. The new system, however, can generate electricity on any gradient, and there is no need to disconnect and recharge the battery. In principle, the technology could be applied to all forms of electric mobility, including cars, ships and spacecraft, he says.

Iwashita was inspired by his experiences during the earthquake and tsunami that hit northeast Japan in 2011. At the time he was working for a general trading company that was involved in petroleum wholesale. While helping deal with an explosion at an oil refinery, he vowed to start a new business based on new technology, but which didn’t rely on existing infrastructure.

An everyday application of cutting-edge tech

Chief Engineer Rafael Jojo Simon, who hails from the Philippines, founded Hello Space together with Iwashita, and has also played a major role in the development of its technology.

His proposal was as follows: “Rather than a full superconducting system – a really big plan – why not first find a social application for our technology in an everyday vehicle, namely a bicycle?”

Hello Space has received a subsidy from the Kumamoto Next Generation Venture Creation Support Consortium and is painstakingly testing its new system with the aim of practical applications.

“If we can reduce the capacity of the battery and its manufacturing costs, eventually the sales price will come down, too,” says Iwashita. “We hope that could encourage society as a whole to shift toward EVs."

The company plans to start demonstration tests of its bike during the second half of 2024, with 100 units being tested in Japan, the US and India. Its goal is practical use of its bikes in society by 2025. Meanwhile, development is happening not just in Japan, but also together with companies in India, Thailand and Taiwan.

Future ideas for the E-bike include converting its kinetic energy into electricity and carbon credits, using the electricity to mine virtual currency, and making it part of green energy generation in society.

For example, the company has created a technology platform called “Smart E-bike Station” that aims to power railway station buildings using not just bicycles, but also propeller-less wind power, superconductor solar power, as well as power generated by humans in gyms.

Hello Space’s work, including the Smart E-bike, received the JR East Award at the 2022 Eco-Tech Grand Prix, a set of business awards supported by major companies. The award recognized the company’s “development of self-powered electric mobility that does not require external recharging.”

In 2025, the company aims to start developing products such as the Mag Drive for E-bike, a power generation and storage unit that can be attached to ordinary bicycles, the Smart Aerobike, which can be installed on fitness bikes and used as a generator in emergencies or at events, the Mag Drive for E-scooter for electric scooters, and the Mag Drive for E-motorbike for electric motorbikes.
