A tricycle rack opens the door to a lot more fun rides. Without a convenient means of transport you are pretty much confined to local rides. This may be fine for some folks but wouldn't it be nice to
be able to ride at the beach or other interesting places?
Although a trike is larger and heavier than a bike they can still be transported without a hassle if you have a vehicle with a trailer hitch. They are simple to mount and safe to use.
The True rack shown below can accommodate one tricycle, one recumbent tricycle, or two 2 wheel recumbent bikes with a few simple adjustments and no special tools. It is adjustable for weight balance and you can even reverse it for convenience.
