Sir Chris Hoy is backing a new clip-on e-bike drive system where power is applied via the rear disc brake. Skarper’s designers say it means a bike can be turned into an e-bike and back again in a matter of seconds.

Hoy, who has been heavily involved in Skarper’s development, has long been a fan of how e-bikes can make cycling more accessible.

“What I’m most excited about with the launch of Skarper is that we are offering something entirely new,” he said.

“People will now have the freedom and flexibility to choose whenever they want electric assistance. Within a couple of seconds they can transform the way they ride.

“I truly believe this is going to make a significant impact on the industry by opening up cycling to a much wider audience.”

Skarper, which will offer a range of up to 60km, was invented by the firm’s co-founder, Dr Alastair Darwood, who has previously invented and developed a number of medical devices used in orthopaedics and anaesthesia whilst working as a doctor in the NHS. This includes an emergency ventilator that was identified for rapid production at the start of the pandemic, which resulted in his working alongside Red Bull Advanced Technologies.

“The Skarper system is fully enclosed and wire free, seamlessly integrating into your bicycle via its DiskDrive™ technology,” explained Darwood.

“It is an ultralight, clip-on motor technology, transforming any bike into an e-bike with no modification required to the frame or wheels, and without compromise on performance.

“We are also very excited to be working with Red Bull Advanced Technologies on an off-road version, news of which will be released later this year.”

Skarper is now taking orders for delivery in 2023 with the final price expected to be around £1,000.
