The emerging crop of mixed-wheel bikes have been described as mullet bikes, so the above is certainly appropriate. But there is more to the new Alchemy NINE7FIVE than just humorous sloganeering: this bike is a serious enduro weapon. With the bigger front wheel, the bike has the ability to mow over any obstacle. And with the smaller rear wheel, it provides the quick handling of a playful 27.5 ride. It’s really the best of both worlds.
