Trike Carrier (or UTC) consists of three durable foam mounts and two
adjustable straps in a convenient carrying bag. It allows any trike
owner (TerraTrike or otherwise) to carry their trike on the roof of any
four-door vehicle safely and easily.
UTC users simply place the foam mounts onto the bottom of their trikes
wheels, load the trike onto the roof of their vehicle, and strap the
trike down using the straps that run through the back and front doors of
the car. The trike can also be strapped down to a roof rack instead of
through the doors. The form-fitting, high-density foam will leave no
scratches on the vehicle (if clean) and pads on the straps cushion the
trike frame from wear marks.
The UTC user manual can be found here.
Because of the added width of the tires, the Rambler AT does not work with the UTC at this time.
