The helmet is rainproof for up to three hours and is set to be sold at bike-share stations for £4.

The designer of a folding, recyclable bike helmet has been named as this year’s winner of the James Dyson Award.

Isis Shiffer made the EcoHelmet from recycled paper woven into a honeycomb structure to protect the cyclist’s head from impact from any direction.

It is covered in a biodegradable coating that makes it rainproof for up to three hours.

Ms Shiffer, a graduate of the Pratt Institute of Design in New York, also gets £30,000 for winning the competition, which is open to university students or recent graduates.
