The Saris MHS 3+1 is a modular three-bike platform hitch rack that’s customizable based on the day’s itinerary. Solo cruise along the riverfront? Party of two riding to the top of the butte? Headed to the bike park with friends? Saris has you covered with individual bike trays that can be removed or added based on the number of bikes you’re carrying. And while the main rack accommodates up to three bikes, you can purchase the MHS Duo Bike Add-On Tray ($350) separately to plop a fourth bike on there.
