Triumph TE-1 final prototype testing results revealed

1 min read

The Triumph TE-1 electric motorcycle project has been completed, with release of the final prototype test results shown to exceed project objectives.

The project is a collaboration between Triumph Motorcycles, Williams Advanced Engineering, Integral Powertrain Ltd, and WMG, University of Warwick, funded by the Office for Zero Emission Vehicles through Innovate UK. It aimed to create ground-breaking developments in specialist electric motorcycle engineering and innovative integrated technology design.

The TE-1 has a 161km/100 mile range, based on live testing and official projections, and 130kW (177PS / 175bhp) peak power, achieving 3.6 seconds 0-60mph, 6.2 seconds 0-100mph. The 220kg bike also has a 20 minute (0-80 per cent) charging time.

Involving numerous assessments of the bike’s performance on rolling road and on track, the live testing programme provided direction into the final set-up and calibration of the TE-1 prototype demonstrator, which has now delivered on all of its targets and objectives.


Regenerative braking has been successfully implemented for TE-1, with scope for further optimisation as well as greater efficiencies in the motor generator unit and transmission, which Triumph believes could improve the range further for its future electric motorcycles.

“Since its conception in 2018, all the partners have worked with collaboration, innovation and passion to bring the boundary breaking prototype to life,” said Dyrr Ardash, head of strategic partnerships at Williams Advanced Engineering. “It is pleasing to hear positive rider comments which confirms that the dynamics of the bike are aligned with Triumph’s DNA.

“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.”
