27.5inch wheels, or 650b as some call, have taken control of the mountain bike market as the most versatile wheel size available. Sure, you will always have the hardcore fans of 29ers praising faster speeds and more comfort over rough terrain, but 29ers lack the agility and acceleration from smaller wheel sizes, like the 27.5-inch wheels. 

650b wheels promise similar speed to 29ers with similar agility to the old 26-inch wheel size. In fact, on bigger travel bikes, like Enduro and Downhill bikes, it’s hard to find a 29er rig due to the notorious reduced performance on slower, more technical trails.

At Bikes Online you can find 27.5-inch mountain bikes on a hardtail frame or dual suspension frame, catering for most riders heights, weights, and likes. Some of the Polygon Bikes also offer a wheel fit system where the wheel size is directly linked to what frame size you choose. Shorter riders will have 27.5-inch wheels while taller riders will benefit from the 29-inch wheel size.
