Hard to take off

The Big Black Box isn't easy to slip on and off. We normally install it at the beginning of summer and take it off for the winter. The motorhome is used throughout the winter here in Maine, thanks to its' heated tanks.

Sorry to hear the BlackBox is difficult to remove. It is large and typically takes two people to remove. We do have a Landing Gear Accessory that allows for mounting of wheels underneath the carrier for easy removal if you are interested.

We recommend and demonstrate the Black Box at every charity bicycle event

We purchased our Black Box and had it installed on our Motor Home back in July 2019 at Let'sGoAero. Our Black Box has traveled many miles and kept our bicycles safe, clean and dry. The entire Team at Let'sGoAero was awesome...they treated us very well. We recommend and demonstrate the Black Box at every charity bicycle event, as we draw a crowd when we open our box and do not have to clean road debris off the bicycles and our chain and drive train is as clean as when we loaded them.

Great shipping

Placement of bikes (using the bike mount accessory) at first was a challenge but once we played with them for a bit it worked out. We were very happy with delivery. It arrived well before our date for pickup of our RV which was a concern of ours.
