Portable Kit Transforms Citi Bikes Into Speeding Scooters [Pics]
ShareRoller turns bike-share units into e-bikes.
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.
