DESIGNING THE WORLD'S LIGHTEST E-BIKE

This project focused on the product design of a custom, machined motor housing, a carbon fibre housed electronics pod and the mechanical assembly of the full system into bespoke carbon bike frames.

​

The system powers the HPS Domestique and the Lotus Type 136 road bikes and at launch, was the lightest e-bike system in the world.

​

The full system was years in the making and spanned across hours of development and concept generation, many rounds of 3D printed prototypes and detailed CAD models with a focus on tight engineering tolerances.

​

The result was a streamlined and aesthetically pleasing system that delivered world class performance.

PROTOTYPING

Using state of the art 3D printers, prototypes were created through out the design process to help test out concepts and to create functional parts that could be used in real world testing.

VISUALISATION

3D renders were used to show how the system could look in real life. This allowed decisions to be made on the material finishes and textures before any money was spent on physical tooling.
