Razor Wind v1.3

Inter-campus Cause for Concern


Razor Wind is the second iteration of campus scooters at Georgia Tech. It capitalizes on a few key upgrades not limited to lighter weight, more compact design, higher top speeds, and ease of maintenance.

Razor Wind, like it's companion Safety Razor, was built using the resources available at the Georgia Institute of Technology Invention Studio.

Posts labeled Razor Wind.

Version 1 featured 'hub motor' technology, in which a DC brushless motor was designed inside of the rear wheel. This motor was custom wound for high torque, such that it could move a person without additional gearing.

Razor Wind is currently on version 1.3: wheelpod edition. The wheelpod is a stand alone drive system that fits directly into the space of the old wheelmotor. It was intended to act as an temporary system but has proven effective enough for sustained use. Its statistics are tabulated below.
