Bosch said it is working on electric powertrains for motorcycles and scooters at the EICMA 2023 motorcycle show in Milan.  The so-called 2-in-1 solution from Bosch offers an integrated motor management concept with vehicle control and inverter. Known as the one-box solution, its compact design frees up storage space in the vehicle for the battery, in a similar way to the Bosch e-axle for passenger cars. In addition, the motor has a passive cooling concept: the drive is cooled by the airstream instead of a complex water-cooling system.

“Especially in Asian countries, where the two-wheeler is often the backbone of mobility, electrification can help bring about huge improvements in local air quality and quality of life,” said Geoff Liersch, head of Two-Wheeler & Powersports.

Thus far the focus so far has been on the smaller performance classes of electric drive systems up to 3 kilowatts, Bosch is now showing its integrated 6 kW electric drive combines driving enjoyment with everyday utility. Its performance figures make the new motor suitable for vehicle architectures such as large scooters or classic motorcycles both in urban environments and for cross-country trips.

“With production starting in 2025, the new Bosch 6 kW motor will enable manufacturers to electrify two-wheeler segments that have so far tended to feature combustion-engine technology. In this way, we’re meeting not only demands for everyday mobility needs in cities, but also the desire for riding enjoyment outside urban centers,” said Liersch.

Demand for Bosch solutions for motorcycles and powersports vehicles is on the rise, and so are the business figures: from 2019 to 2023, Bosch Two-Wheeler & Powersports sales grew by an average of 8%, despite a volatile economic environment. Average growth in the global motorcycle market over the same period was just 1-2%. By 2026, Bosch aims to generate group-wide electromobility sales of €6 billion euros, with some of it coming from its Two-Wheeler & Powersports business unit.

Bosch now has a total of some 500 associates worldwide working on ideas and solutions for the motorcycles, quads, and snowmobiles of today and tomorrow – a threefold increase since 2016. At the same time, the team has access to Bosch Mobility’s network of developers and engineers. “Bosch is a key innovation driver in the two-wheeler market. We offer our customers everything from individual components to complete systems solutions. This makes us successful from both a technological and a business perspective,” Liersch claimed.
