About Spiro Mobility Solutions:

Spiro Mobility Solutions, formerly known as MAuto, is an African electric vehicle (EV) company founded in 2019 and headquartered in Nairobi, Kenya. The company specializes in electric motorbikes and battery-swapping infrastructure, aiming to reduce the continent's reliance on fossil fuels. As of 2025, Spiro operates in six African countries: Togo, Benin, Rwanda, Kenya, Uganda, and Nigeria.

In Nigeria, Spiro has made significant strides by deploying 13,000 electric motorbikes across major cities, including Abeokuta, Ibadan, Lagos, and Abuja. This expansion is part of Spiro's initiative to reduce carbon emissions and promote environmental sustainability. The company plans to establish an electric vehicle assembly plant in Ogun State by the first quarter of 2025, aiming to produce up to 100,000 bikes.

Spiro's business model centres around a battery-swapping system, providing riders with access to swap stations, fast and slow chargers, and home charging solutions. This approach ensures a seamless and efficient riding experience, eliminating the downtime associated with traditional charging methods.

Through strategic partnerships and a commitment to innovation, Spiro is actively transforming the transportation landscape in Africa, offering eco-friendly alternatives to traditional fossil fuel-powered vehicles.
