INNOVATION: Electric bikes are the ideal alternative for urban commuting. Their environmental cost is small, they support physical and mental health and they’re fun to use. The downside? Most e-bike batteries only last two to three years. Zen E-Bikes are different. Thanks to battery technology developed by the Jeff Dahn Research Group, where Ravi Kempaiah is a post-doctoral fellow, Zen battery packs have double the endurance of the competition. And soon, they’ll last even longer.
“Our first-generation battery pack already lasts twice that of a typical e-bike battery pack. And we want to be the first company to commercialize Dr. Dahn’s million-mile battery for two-wheel e-mobility. It would last 10-12 years and reduce thousands of tons of CO2 emission.”
FOUNDATION: Like Dr. Kempaiah, who has a PhD in Li-ion battery science, Zen’s co-founders are enthusiasts and experts: a principal engineer with ten years’ experience in EVs, and a tech solution architect. Backing them up is an advisory board that includes Dr. Dahn, NSERC/Tesla Canada Industrial Research Chair, and Dr. Chris Burns, CEO of NOVONIX.
INSPIRATION: “In 2013, I was doing my master’s and I was adamant that I should not use a gasoline car just to transport me the three miles to campus,” recalls Dr. Kempaiah. “I got an e-bike and thought ‘This is game-changing technology.’ I wanted to bring more attention to it. That’s when I did the Guinness Record ride.” Dr. Kempaiah holds the Guinness World Record for longest journey on a motorized bicycle: 8,209.10 km over 34 days across twelve US states. “It only cost me $6 in electricity! That convinced me that e-bikes are the future. So, I did my PhD working on batteries.”
WHY IT MATTERS: “Long-life batteries for electric mobility—that’s our goal. A battery that lasts 10 to 12 years means less e-waste and better sustainability,” says Dr. Kempaiah. But their ambitions don’t stop there. “The next step? Let’s say you have two e-bikes, they could become an electrical backup for your home during a power outage. In places where the electrical grid is unreliable, you can ride your e-bike during the day and when you get back home, use it to power your lights and radio and other things.”
