As the name suggests this budget model from GT has the great advantage of coming with hydraulic disc brakes specced out the box, a great step up from the V-brakes often seen on entry level machines.
With your braking inspiring confidence it is a good job you can build up some speed with the excellent 6061-T6 aluminium frame, designed with the distinctive GT triple triangle geometry and driven by capable Shimano 3x8 gearing. The women specific geometry also brings a shorter reach for each given size, among other subtle tweaks to improve the female rider fit and experience.
With all these basics covered you will find it hard to come across a better starter bike to introduce you to the art of offroad riding.
