Gravity Coaches and Guides

Mountain bike coaching in Nelson, New Zealand

Gravity Nelson is super excited about how its mountain bike coaching sessions have taken off, and that success is no doubt in part due to the extensive experience and qualifications of our coaches, plus our unique “bespoke, inclusive, enthusiastic, progressive and supportive” approach to mountain bike coaching for all levels and styles of riders.

Our coaches are highly qualified, skilled and experienced riders. We don’t settle for just any old bloke – this team is stoked on bikes and on getting others out to experience the awesomeness of this sport and the rad-ness of the Nelson area.

The Gravity Nelson core coaching team consists of Alistair Matthew, John Butler, Skye Irwin, Callum Bryant, Christine Ma, and Brady Stone.

Below is a small outline of the mountain bike riding and coaching background of each member of our team:
