So my wife is still pushing forward on her Catrike Villager despite the colder temperatures here in NW AR. But I'm the proverbial "cold wimp"... just can't
handle that burn of the cold air going into my lungs and chest.

So, I saw something on a recumbent trike for sale the other day which looked really cool and was apparently for indoor (garage perhaps) training. It was
some kind of stand with a roller which sat under the rear wheel and allowed you to work out indoors on your recumbent trike.

Anyone out there know what this is, if it's any good, and where I might purchase one?

Thanks and Happy Holidays, Merry Christmas, Happy New Year,
