What Our Gearhead(R) Experts Are Saying:"I added this when group rides turned into carpool rides. Setup was straightforward, and it feels just as solid as the base rack. I like that it doesn't change how the rack loads or tilts-it just adds capacity without adding hassle."When rides turn social and one extra bike turns into two, the HoldUp2 Add-On Compact Hitch Platform Bike Rack Add-On keeps plans simple. Yakima designed this expansion to integrate seamlessly with the HoldUp Compact, letting us bring more bikes without changing how we load, tilt, or access the vehicle. The add-on uses the same wheel-secure tray system to protect frames while accommodating modern tire widths and longer wheelbases. Adjustable offset trays help manage spacing between bikes, while the remote three-position tilt still allows trunk access with bikes loaded. For riders who don't always need four-bike capacity but want the option, this add-on delivers flexibility without compromise.
