27.5-inch mountain bikes — also known as 650b — deliver a lively, playful feel on the trail. With quicker acceleration and more agile handling than their 29-inch counterparts, they're ideal for riders who love flicking the bike through corners, pumping terrain and keeping things fun.
Why choose a 27.5-inch MTB?
If you prefer a bike that feels nimble, responsive and easy to manoeuvre, 27.5-inch wheels offer a brilliant balance of control and fun. Trail riders and progressing riders often love the confidence they provide. For more speed and stability on rough terrain, explore our 29-inch MTBs, or if you want something tougher for jumps and pump tracks, check out Jump MTBs.
