Smith Creek Cycle

Welcome to Smith Creek Cycle, your premier destination for all things cycling in the beautiful Okanagan region. Established in 2020 and proudly owned by Brian McClelland, our small bike shop is passionate about serving the local cycling community and beyond.



My experience with Smith Creek Cycle was fantastic. I had a basic idea of what I wanted but Brian really ran with the idea and delivered something well beyond my expectations.

These guys are the BEST for bike maintenance... they really take the time to check everything, explain it to me before doing anything and letting me know what will be coming up. Such a relief as I'm not well versed in the bike maintenance world... so great to feel like it's being taken care of. Highly recommend.

Great job on a recent tune up, honest advice on parts and they charge a fair price for work performed. The techs working on your bike take pride in their work and treat them as if its their own. Will be back for all services and new bikes purchases in the future.
