Christine Ma

Owner and Coach

Hi! I’m Christine and I’m originally from Ontario. While I didn’t discover mountain biking until my adult life, it has made me love and appreciate the dedication required to improve that much more.

After 10+ years of experience in the Outdoor Adventure industry around Canada and New Zealand, my skills, knowledge and passion for sharing the joy of biking have led me to create Ridetheory. Who knew that dogsled guiding or working ground crew for a heli-ski company could eventually lead me here?

Using my PMBIA Level 2 Mountain Bike Instructor certification and M.Sc in Kinesiology (Biomechanics), I enjoy helping all demographics improve their mountain bike skills – especially women. Having co-created one of the first women’s only programs in Nelson, NZ, I understand the mental and physical challenges that present themselves in a male dominated sport. Regardless of who you are, I encourage you to get out there and have fun on a bike!

Aidan Jones

Aidan grew up on two wheels, following his parents as they raced cross-country mountain bikes in the Eastern United States. This led to his love of bikes, which saw him transition into racing BMX, downhill, and enduro to this day. Outside of racing, Aidan has worked in the bike industry in many roles which include being a bike mechanic, trail builder, guide, and Level 2 coach. Aidan loves to share his passion for bikes with others in any way he can. When not riding his bike or working in the bike industry Aidan owns a photography business that allows him to travel BC, capturing skiing, weddings and landscapes.

Coach David Golls

David Golls

Fernie/Kimberley Coach and Guide

David has been playing around on bikes since 1989, starting by riding hardtails and bouncing around with only one inch of travel. David honed his skills through riding the technical single track in Whistler, BC during the early 1990s and progressed into XC racing before retiring from racing in 2000. David turned to Coaching 10 years ago and along with being a Dakine and TREK brand Ambassador, David is rolling through life on two wheels.

Coach Simon Leclair

Alina Jackman

Fernie Coach and Guide

Alina is a passionate mountain bike coach whose journey on two wheels began with a quest for freedom and happiness. Formerly she was an elite swimmer and lawyer who found much more joy in skiing and biking. Alina transitioned from a legal career to chase winters and pursue her intense passion for slope grooming, mountain operations, and ski instructing. Currently, Alina coaches for the Fernie Alpine Ski Team as the U10 Head Coach, cherishing her FAST Family and Athletes.

Discovering mountain biking after years of road cycling, Alina got a taste for mountain biking on technical trails and challenging climbs. A preference for techy trails, features and gravel defines Alina’s riding style. After returning to biking after years of back-to-back winters Alina is most often seen in the mountains either on skis or bikes.

Alina embraces coaching as an opportunity to give back, with a strength fostering confidence in all riders. Her experiences have instilled a desire for learning and helped make her empathetic to others as she strives to be the Coach she needed when growing up or when trying new things in an environment that is positive and without prejudice.

Every day on skis or bikes is the best day!

Tanner Smyth

Fernie Coach and Guide

Tanner is originally from Ontario and has a long standing passion for riding bikes with the majority of his experience on BMX and skateparks all around the world. Over the past couple of years, he has been applying these skills to mountain biking which has sparked a new love for flow trails and dirt jumps.

Tanner has recently finished a 2-year outdoor adventure program where he became a certified guide & instructor in various activities including mountain biking. With experience in a wide variety of scenarios, he has learned the importance of keeping the sport fun and making the most of every situation. He is super excited to have the opportunity to help people progress in their riding and create an enjoyable, supportive environment.

If Tanner is not biking on a mountain, he’ll most likely be found with a backpack and tent hiking up them. He is looking forward to expanding his own knowledge of mountain biking as well as spreading the love of the sport.

ridetheory coach clayton cardarelli

Clayton Cardarelli

Cranbrook/Kimberley Coach and Guide

Clayton was born in North Idaho to a bike family. Some of his earliest memories are being packed around by his parents in a chariot (with lots of snacks, of course!), going up gravel passes and riding on ferries in the Kootenays. Growing up with those experiences, he learned how you can use bikes to explore.

At the age of 19, Clayton took a year off work and school to bike tour from Idaho to St. John’s, Newfoundland. All was well until his chain snapped outside of Highland Mountain Bike Park in New Hampshire. The folks at the shop laughed while working on his touring rig in the stands typically reserved for downhill bikes, and they showed him around the Bike Park. Ever since that day, Clayton traded out his touring gear to explore the gravity elements of riding, and of course, the endless access to amazing terrain that trail riding affords those who venture.

Clayton firmly believes in the magic of bikes to empower people of all ages and to provide a life of rich experiences. He’s stoked to share this passion as a coach, helping build confidence and ability to enjoy mountain biking as a life-long journey on some of his favourite trails in the world, here in the East Kootenays.

What People Are Saying

Jena was great! Informed, positive, enthusiastic. She did such a great job of sharing her knowledge, providing lessons, and encouragement. She had great information and was great at helping everyone out.

- Carrie W.

I'm so incredibly glad to have taken a lesson with Ridetheory- Christine was fantastic at creating a safe, comfortable setting and tailored the class to move at my pace. I was admittedly pretty nervous while approaching some difficult skills, but I found her positive reinforcement, encouragement, and obvious enthusiasm for sharing the sport made the lesson so much fun. I would highly recommend Ridetheory to anyone who else who is interested in the sport but unsure how to begin!”

- Stephanie N.

"As a somewhat new beginner, I was looking for instruction to help me gain confidence on the trails and the two private lessons allowed us to work at my pace. My instructor was great at finding ways to explain new techniques to me, then gave me practical ways to practice them. I highly recommend Ridetheory!"
