Triumph Motorcycles has completed testing of its new Project Triumph TE-1 prototype fully electric motorcycle. The company and its collaborators have spent six months on a live testing program for the battery-powered sport bike on road and track.

During the trials, the TE-1 achieved a 100-mile (161-kilometer) range and a 20-minute charge time from 0 to 80% of battery capacity. Both are exceptional numbers in the electric bike segment. So is the TE-1’s 485-pound (220-kilogram) weight, which is up to 25% lighter than comparable electric motorcycles. With 175 brake horsepower (130 kilowatts) of peak power, the prototype accelerated from 0 to 60 mph in 3.6 seconds and from 0 to 100 mph in 6.2 seconds.

Collaborative Success

“We are incredibly proud to be able to share such positive outcomes from the completion of Project Triumph TE‑1, where the prototype demonstrator has exceeded many of our initial targets and expectations,” says Triumph Motorcycles CEO Nick Bloor. “Everyone on the team is thrilled with the results we have achieved with our partners, and how the outcomes of the project will feed into the electric future to come from Triumph.”

The Project is a collaboration among Triumph, Williams Advanced Engineering (WAE), Helix (formerly Integral Powertrain), and WMG at the University of Warwick in the UK. Funding for the project came from the Office for Zero Emission Vehicles (part of the Department for Transport and the Department for Business, Energy and Industrial Strategy) through Innovate UK.

High Power Density

Helix came up with the TE-1’s high-power-density electric powertrain with Scalable Integrated Modular Inverter (SIMI) technology. The compact, 33-lb (15-kg) assembly combines a scalable electric motor and a silicon carbide inverter, which helps the bike to attain its high power-to-weight ratio.

“It is pleasing to hear positive rider comments which confirm that the dynamics of the bike are aligned with Triumph’s DNA,” says Williams Advanced Engineering Head of Strategic Partnerships Dyrr Ardash. (Photo courtesy of Williams Advanced Engineering.)

“In its TE-1 application, the motor achieved peak and continuous power densities of 13 kW/kg and 9 kW/kg, respectively—60% higher than Advanced Propulsion Centre technology roadmap targets for 2025,” says Helix Chief Technology Manager Andrew Cross. “All this was achieved using materials and processes compatible with volume automotive production and using a motor scalability concept that provided a springboard to our Scalable Core Technology, providing similar performance levels at much greater manufacturing scale than previously possible.”

Range & Recharging Time

Williams Advanced Engineering developed the Triumph TE-1’s battery pack, which has a very rapid recharge time for the nascent electric motorcycle segment.

“It is pleasing to hear positive rider comments which confirm that the dynamics of the bike are aligned with Triumph’s DNA,” says WAE Head of Strategic Partnerships Dyrr Ardash. “This has been underpinned by the class-leading battery and control system that WAE has produced within a lightweight and integrated package. This core WAE technology has allowed us to exceed performance and charging targets for the battery which we look forward to seeing in future powertrains.”

The TE-1’s motor generator unit, transmission, and regenerative braking system may allow for further optimization in efficiency, which could translate to even greater range for derivative electric motorcycles in the future, according to WAE.
