Bike Size

Please note, our size chart is a recommendation and will not work for every rider. When selecting the ideal bike size, especially if you find yourself on the edge of the recommended height range for two sizes, it's highly recommended to test ride both options or consult a bike fit expert for their opinion. Another method of finding the right fit is to compare the geometry of your current bike, or one you are comfortable on, and match it to our geometry numbers.

Bike Handling

If you are in between sizes, consider the ride feel that appeals to you. Larger bikes tend to feel more stable and planted and require a bit more body movement to manoeuvre. A longer wheelbase offers a smoother and more predictable ride. Smaller bikes will feel more agile and are generally easier to handle when things get tight. The shorter wheelbase will feel less stable at high speeds, but more responsive.

Unique Body Dimensions

As we know, we are not all made the same. You may want to take into account your unique body dimensions, as longer legs and a shorter torso may steer you toward a smaller size, while a longer torso and arms might lead you to opt for a larger frame.
