Sturdy and smooth.
Many exercise bikes have one thing in common - they flex and creak way too much. This one does not. It will slightly flex when giving it high RPMs at very high resistances, but it's not more flex than an actual bicycle would give you. The resistance and action feels very smooth.
No bells and whistles. A couple of programs displayed on a small screen with four buttons. No stupid computer fans, elaborate magazine racks, sporty graphics, memory or any of that crap.
Many exercise bikes have seats that look like they would stink from soaking up your sweat. They're too thick, feel like a couch. You need firm support that's easy to clean and won't make you go numb - and this seat does that. Excellent lumbar curve, and if you grip the back of the handlebar, you can maintain proper posture during sprints.
It feels almost as good as the commercial one I use at physical therapy - and that is a $4,000 machine. It also feels a million times better than the common ones like schw___ and naut____. This is one of those rare occasions where you will get more than you paid for. If this bike proves to last more than a year of heavy use, I would say that it's worth the price. However, I'm thinking it's going to last at least 5 before it needs replacement parts.
Oh yeah - it looks good too. It's the simplest, cleanest design out there. Get an equipment mat and put it in your living room - it won't look bad.
