Gear hub provides a smooth ride and it is a low maintenance solution.
Dropout locks and secures the rear wheel. Discourages theft of easy removable parts [major concern in urban commute].
GPS and saddle lock
A GPS is integrated in the seat tube, enabling the user to alert the police in case of bike theft and recovering the vehicle. It is powered by a small battery that is charged when the main battery is mounted.
The saddle is locked in the frame by a rivet, rendering it hard to be removed.
Integrated lights
Modern bike commuters in most cases share the road with motor vehicles. It is crucial for the safety of the rider that he/she is visible to the rest of the road users, as well as, he/she has good visibility of the environment.

The commute often includes stops to the super market or other stores.
The baggages must be secured when the vehicle is in motion.
