Have you ever opened the cargo door to your trailer to be greeted by your bike lying on its side? If so, then KNOCKRZ might be just what you need. These heavy-duty air bags can hold up to 500 lbs. of dead weight should a strap slip or come loose while you’re rolling down the highway or bouncing down a back road.

The KNOCKRZ kit comes with a blower that plugs directly into a battery harness or standard 12-volt plug with the included adapter. With my bike set in the middle of the trailer, I placed the KNOCKRZ on either side and the blower filled them up quickly. The nozzle included with the blower fits right into the KNOCKRZ, and can also be moved to the side of the pump to suck the air from the bags for more compact storage when not in use.

With my bike firmly supported by the KNOCKRZ, I took off the straps holding it in place and pushed, pulled, and shook the bike… it would not fall over! KNOCKRZ are made of a heavy-duty reinforced material intended to stand up to long-term use. When hauling multiple bikes, the KNOCKRZ can be placed between them to prevent damage during transport.

Sometimes you have to trailer to a rally and when you do it’s comforting to know that your bike is safe and sound in the trailer, nestled between a set of KNOCKRZ. Check their website to see the different configurations available and to learn how KNOCKRZ can help protect your bike. MSRP: $75–$149.99 Knockrz.com
