Pros: Very ergonomic. Quiet. Solidly built. No problems.
Cons: None that I can think of.
I've owned my Tunturi F520 recumbent exercise bike for over 4 years. I already had a treadmill but wanted a bike for variety. I did all my researching online. What set the Tunturi bike apart from all the others was that it had a low profile, perfect for watching tv.
After setting my sights on this machine, I reviewed other Tunturi products to see how satisfied others were with their purchases. I had never heard of Tunturi but I knew I liked their design. Some of the things I read about the bike that I liked was the quiet magnetic wheel, the seat & backrest, and the easy adjustments.
I did a search online and found an exercise shop in CA either in Redwood City or with the name Redwood who included shipping to my door for free. It was a very simple purchase to make over the phone. It required assembling the seat and attaching the pedals, which was pretty simple.
This model looks just like the F530. I hope Tunturi sticks to building quality exercise machines, I'd look to them if I were going to add to my personal gym.
