Police Driving Instructor Senior Constable Too Chi-hau who conducted the eco-driving training, pointed out: "The Vectrix is very different from a normal motorcycle as the rider cannot use the sound of the engine to determine gear and adjust throttle; so this can be a little eerie for novice motorcyclists."

Riders have very quickly adapted to and praised its handling in a variety of circumstances, including use of a unique "multi-function throttle" that provides for regenerative braking in what amounts to a reverse gear.

Constable Ng Lui-sun from Sha Tin Division commented: "I have three years' police motorcycling experience and found the scooter very easy to handle and control. The transmission and better seating design really make it a pleasure to ride. The provision of other features, such as a windshield and bright front headlamp, is a definite improvement."

Constable Ngan Siu-ming from the same division also has three years police motorcycling experience and rides his own 400-c.c. scooter to work. He commented: "The new scooter is very easy to handle and has performance characteristics similar to my own scooter but the throttle is more responsive than police motorcycles. I also like the 'reverse gear' feature which is not available on other motorcycles."

Constable Lo King-fat from Sheung Shui Division is a little more wary. "I like the handling but I am not sure whether the bike will be up to task for frontline work as its range is limited, compared with a conventional motorcycle."

Time will tell when trial of the first few zero emission vehicles is extended to other formations over the next few months, including Traffic.
