Developed by Jeff Guida, an electrical engineer from New York, ShareRoller is a portable and detachable electric motor kit designed for bike-share programs.

The portable electric motor is shaped like a briefcase and is attached to the mounting bracket above the front wheel of the bike. It comes with a thumb throttle that clips to the handlebars and allows the rider to control the motor. The portable motor also has built-in LED headlights for added safety on the road.

The motor provides 750 watts of power, allowing the user to ride along at a speed of up to 18 mph without pedaling. The rider can also choose to pedal along as much he or she wants.


Aside from letting bike riders get to their destinations faster and with relatively less effort, ShareRoller also has USB ports to allow them to charge up their devices on the go.

ShareRoller currently works with 11 major bike-share systems in the US, Canada, and the UK since they use the same type of heavy bike model. It also works on a Xootr kick scooter. Guida is currently developing mounts for other bikes and scooters.

Guida is launching a Kickstarter campaign for the ShareRoller on February 28th. Prices start at $995 for a ShareRoller.
