Three is the magic number

A multi-functional three-wheeled vehicle that weighs 19kg and can carry an average adult 20km on a single charge will be released this year.

The eFOLDi has been designed by Surrey resident Sumi Wang and her father, renowned Chinese engineer Jianmin Wang, and has been chosen as a finalist for Gadget Show Live British Inventors’ Project.
As a result eFOLDI has been given a stand at the award-winning Gadget Show Live exhibition – the UK’s largest consumer technology exhibition – which will take place at the NEC, Birmingham from 31 March to 3 April.
The mobility device will be launched globally later this year following a Kickstarter campaign.
Sumi said, ‘An inventor’s mind is always at work and when my father Jianmin broke his leg, he decided to design his own method of transport to get around. While there are a lot of electric scooters available, Jianmin realised that there were no effective folding scooters that could be easily packed away to take on public transport while also proving secure over rough ground.
‘After some time in the workshop, the result is a scooter that weighs only 19kg, can carry an average-sized adult over 20km on a single charge and can be folded into an easily-transported piece of luggage.

‘eFOLDi can be programmed with three different top speeds for different needs: 4mph if it is being used as an off-road mobility aid, 8mph for mobility use on the road and 12.5mph for recreational use by normal road users.’
