Adding an extra bike to your Saris Modular Hitch System (MHS) base hitch rack is quick and simple with the MHS Duo 1-Bike Tray. Compatible with any MHS base, this add-on holds a bike up to 60lbs, a wheelbase up to 53in, and wheel sizes from 20 to 20in, all without ever touching the frame of your bike. The dual-arm holders, which feature tool-free adjustment, give your bike stable transport to your favorite trail. Saris integrated a cable lock to secure your bike when you run into your favorite cafe to grab some post-ride grub.
