We are a group of passionate cyclists and skilled individuals. Professional, energetic and engaged in the community, we're happy to share our bike passion with the people of Canterbury. Independently owned, we've been selling and servicing bikes and gear since 2000.
We're on the YouTubes.
Riding the all-new Turbo Levo SL
Our Top to Bottom series features raw footage from our local trails. The bike is a 2020 Specialized Turbo Levo SL Expert, one of our shop test bikes. Weighing only 18kg (39.7lbs), it really is a nimble, fun e-bike and feels just as playful as the Stumpjumper.
The Crowning of Champions
We saw some incredible races during Aotearoa Cross Fest '19 with Jacob Turner battling it out with three others to take the win in U19 Male and Kate McIlroy and Brendon Sharratt claiming the crowns in Elite.
Mud, Beer and Wetsuits
Aotearoa Cross Fest '19 was a huge success! Two days of good cyclocross racing, food, beer and heckling from all of our awesome CX friends. Saturday was the fun day with 3 races, Beer Hand Up, Team Relay and a Run What You Brung race.
Latest from the blog.
Our shop is closed until further notice and the web store is closed, too.
The Turbo Levo SL is the all-new lightweight electric mountain bike from Specialized. It takes the quick and lively ride of the Stumpjumper and adds just enough power to help you up the hill.
