Question:

I've got a 2026 Sierra 1500 AT4 and were starting to take our mountain bikes camping more often. I usually tow our little travel trailer, so a hitch bike rack isn't really an option. I've been laying the bikes in the bed with blankets between them, but Id like something that keeps them upright and separated. Is there a system where I can remove the holders when were not riding?

Hey Nathan!

I recommend the Z-TRAK Cargo Rail # ZT54FR for your 2026 Sierra 1500, along with two Z-TRAK Bicycle Wheel Chocks # ZT44VR.

These are designed for regular bicycles, including mountain bikes, and have built-in ratchet straps that secure the front tires. They also hold the bikes upright while you're loading, and you can reposition or remove them without tools.

For additional security, especially on longer trips, I'd add a pair of Z-TRAK Tie-Down Straps # ZT92FR (or # EM05729 for a budget friendly option) to help stabilize the bikes. The reps at Z Trak assured us that the straps aren't required, but are recommended.

The nice thing about this setup is that you can leave the rail installed and remove the bicycle holders when you need the bed for camping gear. The rails barely stick out from the truck bed rail so you won't even notice they are there after removing the bike chocks.

Are you both riding regular mountain bikes, or is either one an e-bike? That'll help us double-check the wheel and tire sizes. There are fat tire options available too.
