Inventors from Shenzhen have created an electronic bike which folds up and fits in a backpack.

The Smacircle can reach speeds of 20km/h and is controlled with a smartphone app.

The eBike folds up into a backpack in less than 10 seconds, by which time it’s no taller than 49cm.

The bike weighs a little over 7kg and can accommodate riders of various sizes.

The first models have been made and tested, and its makers are seeking further investment with an upcoming Indiegogo campaign to bring it to the mainstream market.

The designers believe it might change the way people commute* to work.

Smacircle CEO Gavin Yang said: “Smacircle is a unique innovative design created to fill in the gap in short commute personal transportation. Our team has spent countless hours on research and development, and are committed to bring the people the best possible solution for short commutes.”

“The pedal-free eBike can connect to everyone’s mobile phone through Bluetooth, and it can help to lock or unlock the bike, it can adjust the speed, and monitor the life of the battery,” he said.

Designers say that in the future they want to build a GPS* that can be attached to the cycle.
