More than 3 million motorbike taxis, or mototaxis, cruise the roads in East Africa. In Kigali, the capital of Rwanda, these petrol-fueled slim bikes make up more than half of all vehicles and are just large enough to carry a driver, a passenger, perhaps a goat, and maybe a basket or two of food or charcoal—but not much else.

Although these mototaxis are an efficient way to move people (and sometimes animals) from place to place, they are also, unfortunately, a large source of greenhouse-gas emissions. What’s more, the mototaxi drivers, known locally as motars, make very little profit once they cover the cost of their motorbikes and fuel.

Enter Ampersand, a sustainably minded start-up in Kigali. The company makes a battery-powered motorcycle, which has the dual benefit of eliminating mototaxi air pollution and helping drivers’ profit margins.

« A lack of viable urban public-transport options and the higher cost of cars means motorcycles play a key role in both urban point-to-point transport and in rural areas connecting people to towns and transit hubs, » says Alp Tilev, Kigali resident and Ampersand’s chief technical officer. « The technology itself is decades-old, cheap, and easy to fix, and the price tag—$1,000 to $1,600—makes mototaxis much cheaper than cars. »

Before beginning Ampersand, CEO Josh Whale spent years in China, researching low-cost electric vehicles (EVs) and gaining insights on making petrol-centric businesses profitable, purposeful, and electric.

« At a time when Western countries were so excited about a few hundred thousand Teslas and retirees were buying up electric bicycles and dreaming of the day we’d all be driving electric cars, China already had 20 times more EVs, and most of them cost less than $200, » Tilev says.

As an early start-up, Ampersand received a software donation from the Autodesk Technology Impact Program to help support its vision of cleaning up Rwanda’s mototaxi business. « While many people looked years ahead to forecast when an EV would simply cost less to buy and run for middle-income Americans, Josh realized that this ‘tipping-point’ moment would happen for different vehicle fleets at different times and places in different markets, » Tilev says.

In other words, densely concentrated markets of high-intensity fuel users—for example, sub-Saharan Africa, specifically cities such as Kigali—would usher it in a lot sooner: « Fuel is expensive, and the users really care about their fuel spending, » Tilev says. « Here in Rwanda, mototaxis cover 190 kilometers [118 miles] a day, six days a week, and spend much more on fuel than they take home at the end of the day. »

Although Whale knew the future was in electric mototaxis, an option that could go head-to-head with the petrol-fueled motorbikes just didn’t exist. He decided then he had to create it. « The Chinese bikes were all underpowered and had low-range, unsafe batteries, » Tilev says. « The upmarket bikes like Zeros and Altas were too expensive, and no electric motorcycles are really optimized to be cost-competitive with petrol for intensive users. »

Plus, Tilev says, off-the-shelf vehicles from China are built for Chinese customers who drive short distances, slowly, in flat cities.

« The roads in this part of the world aren’t famous for their immaculate state, so having a vehicle that can hold up to sustained abuse was important, » Tilev says. « So when it came to ‘make or buy,’ there was just no ‘buy.’ »  As Ampersand began prototyping, the design team used Autodesk Fusion 360 to make quick assemblies for the test rigs. « This was critical in the early days of our prototyping phase, » Tilev says.

And when it came to the primary directive of the electric bikes—a rechargeable, swappable battery pack—what Whale and the team at Ampersand wanted didn’t exist. They had to make that, too.

« The swappable pack is incredibly important, as it requires the minimum behavior change from the drivers, » Tilev says. « Most drivers are used to putting in fuel one to two liters at a time already, and mototaxi drivers work 12 hours a day. They don’t have time to sit around and wait for their battery to charge. They are busy and hustling for customers. »
