Great design...more to come!
I only have a few miles on this unit; but, will update after 2,000 miles. So far, well engineered and thought out.
This unit has reflectors; but, I think it comes with trailer-hitch electrical connections and lights in other countries. That would be a nice option in the U.S., but the reflectors are a nice touch. This unit does sit a decent distance from the rear of the vehicle (hitch extension plus 2-bike width); and, a following driver's depth perception (especially at stop lights) is a minor concern on my part. I still attach a red cloth and reflector on the outside bike to help.
This unit will be used for cross-country trips with a mountain and a ride bike. I have heavy canvas bags to shroud each bike, but do not have any experience with the level of grit I take on. The bottom is closed and provides some protection.
So far, the hitch stabilizer seems to work very well.
