A new folding, electric bicycle is being developed by a team of Formula 1 motorsport engineers and leading brand Brompton.

The challenge involves designing a bike with an engine powerful enough to make a difference that is also light enough to be carried while folded and robust enough to cope with cobblestones, potholes and other hazards.

The new model would be a “pedal assist” bike in which the rider’s strength is augmented by the engine on hills and when they want to go fast. These have proved increasingly popular among commuters as they prove a degree of exercise while avoiding the need for a shower after arriving at work.

Brompton’s chief design and engineering officer, Will Carleysmith, said: “It is no secret that we have ambitions to develop an electric pedal-assist Brompton.

“The bike needs to be built to the highest standard like all our bicycles and stand up to the challenges of city life.”

He added that they were working with Williams Advanced Engineering, which converts F1 technology for use in other sectors, to harness “their extensive engineering expertise”.

A Brompton spokesman added: “They have [Williams] access to technology that a company like us couldn’t possibly afford or have access to. We build bicycles, not motor-driven products in any way. They have technology and expertise we don’t have.”

In a statement, the firm said it saw “huge potential in the electric pedal-assist bicycle” to improve travel in cities.

“The release date has yet to be finalised, but good progress has been made, the bicycle will be ready when it’s ready,” Brompton said. “The product, like all previous Brompton bicycles will be developed and manufactured in London.”
