We designed our Corvus, our classic diamond city bike for you. From hand-selecting top of the range components to rigorous testing giving you the best riding experience possible. Our bikes are just perfect for everyday commuting as well as casual riding. Featuring puncture-resistant tyres, an elegant hi-ten lugged steel frame, chain guard and full fenders. Dual-pivot brakes with quick release, 3-speed Shimano Nexus internal gear, PU leather saddle and handgrips, sprung carrier and built in front and rear LED lights. We also went the extra mile to add alloy components where possible so you can ride rain, hail or shine. Bottom line is our bikes are built for living, riding, and thriving.




Corvus’s diamond frame maintains the sleek and classic tradition of city style cycling. A constellation of simple cycling pleasures. Colours available in Raven black and Blue straggler. Take flight and slake your thirst for the gems of your city.

*Do note some riders may be a little outside these height range recommendations. Stand over height measurement is not as important as how the bike geometry feels while it is being ridden. As long as the rider can reach the ground while sitting on the saddle, even if it’s just their toes, this size will be compatible with their height.

ABC’s commuter bicycles are highly functional as they are stylish. Using the modern materials while retaining a vintage look and feel that is timeless as it as bold for the new world. Designed locally in Christchurch, New Zealand.
