The Quarter is one of the lowest-profile helmets we’ve ever made, and it’s also the lightest we’ve made with an ABS shell. The essentials are here – an EPS liner for impact management, a tough outer shell, riveted webbing anchors and plush, sweat-absorbent pads for long-lasting comfort. Another standout feature -- the Roc Loc Vert dial fit system allows you to easily adjust the helmet for a secure and stable fit. Available in a bunch of great colours and three Super Fit sizes.

How is the frame size measured?
Most E-bikes are measured from the centre of the crank to the base of the seat post tube. However, some E-bike manufacturers may measure their bikes differently depending on their style.
