The Hill Bill impresses with its well-thought-out geometry, ergonomic components, and a wonderfully low weight. Combined with disc brakes and very lightweight tires, it is the perfect bike for those first trail adventures. Additionally, both the 24" and 26" models come equipped with a truly child-friendly suspension fork. So small, yet already a true Hill Bill. In fact, the 20" Hill Bill features all the attributes of its larger counterparts, such as a 12mm thru-axle at the rear wheel and a lightweight, multi-conified aluminum frame. The only thing we forgo here is a suspension fork due to weight and functional considerations. Instead, the tires are a substantial 2.35" wide, providing plenty of suspension support.
