When Elon Musk published Tesla’s first “master plan” in 2006, it seemed a bit far-fetched that batteries would end up changing the automotive industry, much less global power production and consumption. Today, as electric vehicles continue to gain market share and massive batteries displace smoke-spewing power plants from the electrical grid, that notion seems less improbable. This year in the U.S. alone, developers are planning to add 15 gigawatts of grid-scale battery capacity.
Yet Michael Spencer thinks that the shift that’s occurring in places like the U.S., Europe, and China is just the beginning. “The Tesla master plan has more legs and more room to run with lower hurdles in emerging markets,” he told TechCrunch.
To prove the point, Spencer, a Tesla alumnus, founded Zeno in 2022. The startup, which until now has operated in stealth, has been methodically exploring how batteries might transform life in emerging markets, beginning in East Africa. The company has attracted considerable talent, including Swaroop Bhushan, who helped design Lucid’s powertrain; Rob Newberry, who helped oversee development of Apple’s AirPort and Apple TV; and others from Gogoro, Tesla and more. Zeno’s first product is a motorbike with a swappable battery.
But in Spencer’s vision, that’s just the start. Swappable batteries won’t just be powering motorbikes in Africa, but other parts of their lives as well.
Motorbike taxis, known as bodaboda, are ubiquitous in East African cities, helping people navigate choking gridlock for far less money than a taxi or personal car. For drivers, though, the costs can be astronomical. Motorbike taxi drivers spend a disproportionate amount of their income on fuel, about 50% compared with a few percent for commuters in California, Spencer points out.
Taking a cue from Taiwanese-startup Gogoro, which helped pioneer the battery swap concept in scooters, entrepreneurs throughout Africa put their own spin on it. The bikes are sold with holes in their chassis where drivers plug in rented batteries. When the packs are near empty, drivers can find a nearby location to exchange it for a fully charged one. As a result, swap stations from startups like Ampersand Solar, Arc Ride, Roam, Spiro, and Zembo have sprouted like grass after a monsoon rain.
Zeno is the latest entrant to the field. The company started by testing around 40 Chinese-made electric motorbikes in various models in Kenya to see how they’d fare. It only took a couple months before the bikes were trashed — they simply weren’t designed for taxi duty on East Africa’s harsh roads — but Spencer said the experience validated his thesis. It also turned up something else.
“There were lots of questions around, like, ‘Why can’t I use this battery for other things?’” Spencer recalled. “We saw some people trying to hack batteries when the power went out, to try to run the lights or to run the flour mill in their shop.”
The Zeno team knew they’d need more durable, heavier bikes that could carry a driver, a passenger or two, and possibly some cargo. It’s working with a manufacturer in India to produce bikes to its specifications, and soon after that model launches, additional manufacturers will release their own two-, three-, and light four-wheel vehicles that will be compatible with the startup’s batteries, Spencer said.
Bigger bikes demand more power, which means they need bigger batteries. Zeno’s lithium-iron-phosphate (LFP) battery packs store 2 kilowatt-hours of electricity, and its motorbike will accept two packs. With one midday swap, that will give the bike slightly more range than most taxi drivers need in a day, Spencer said.
The extra capacity “opens up all these other doors.” Spencer and his colleagues started building docks so people could use the motorbike’s spare power to charge phones and run various appliances.
“We prototyped an induction cook stove that ran off of our swappable motorcycle battery and got a pretty cool little microcosm,” Spencer said.
Motorbike taxi drivers could drive home after a day of work, hook their batteries up to the stove to cook dinner and then breakfast the next morning. At that point they would have 10 to 15% charge left, which is enough to drive back to town to swap for a full battery at a self-service station. Every part of the system will have internet connectivity so the company can monitor the batteries, anticipate demand, and facilitate financing. The bikes use a Type 6 connector so that drivers can plug into public chargers during a lunch break, for example, or charge overnight at home if the need arises. The company is also building a charging network that will be available to non-Zeno drivers.
Zeno’s first motorbikes will hit roads in East Africa and India in early 2025. Customers will have to buy or lease the vehicle, which will cost less than a new gasoline-powered model when configured without a battery. The startup will lease the batteries under a subscription model (though people can also buy the battery outright if they choose). Customers can add energy to the subscription bundle or buy it separately on a pay-per-use model. Zeno’s goal is to undercut gas-powered bikes with the upfront cost of a bike and initial battery subscription. And because the power costs of electric motorbikes are about half that of a gas model’s fuel bill, Spencer said the savings improve over time.
Shortly after the bike launches, the company plans to release its home battery dock with an available solar panels, which Spencer hopes will open new markets.
“If you don’t have grid connectivity, you can bring your batteries home from a swap station, and you can use them to power your home. If you want to put solar on your house, that home docking station works as a solar inverter to charge those batteries. So you can be a Zeno battery subscriber for a decade and never swap batteries.”
To fund its launch and expansion, the company recently raised an oversubscribed $9.5 million seed round led by Lowercarbon Capital and Toyota Ventures with participation from 4DX Ventures, Active Impact, Advantedge, MCJ, and RedBlue.
Zeno’s playbook certainly has echoes of Tesla’s, offering customers electrified transportation with a lower cost of ownership. But by focusing on a portable battery, Zeno is selling the ability to use energy whenever, something more akin to how people use fossil fuels today. The motorbike is a central part of the sales pitch, but the battery might be the real selling point.
