My wife recently had an ACL repair and is just starting the bike riding part of her PT. While she is active and physically fit, she had never been a road biker (a light mountain biker at best) but is interested in stationary bike for home. I would prefer to setup a Zwift trainer for her to minimize the monotony of riding a bike indoors without spending $2000 (the Peloton we have considered).
Any suggestions regarding the approach (i.e. road biker with trainer vs stationary bike) and recommended equipment would be greatly appreciated.
