    I love to work out but am not a "Spinner." However, I was looking for another piece of equipment to add to my home gym. This allows me to cross train--20 minutes on a treadmill, 20 minutes on my spinner, and 10 minutes of weights. It's perfect for what I was looking for.

    Good bike but the seat tilts forward as soon as you sit on it .Frustrating.

    The handlebars do not extend up very far so you are forced to "ride" in a very aggressive position. The seat is also very stiff.

  • Very quiet and easy to move
    Verified Purchase

    So far I am very happy with this bike. The seat is very uncomfortable so I replaced it, as other reviewers have suggested. I ordered this because I have problems with my feet, so treadmill use is not an option for me. I am pleased with my purchase and was amazed by the speedy delivery.

  • Great for the money
    Verified Purchase

    After changing to a gym that didn't offer spinning classes I decided my withdrawls outweighed my desire to focus on the treadmill and I bought this after doing some research. I wanted the B-901 model but it was unavailable and overpriced on another site. This bike is QUIET! It was easy to put together by myself and wheels from one room to another very easily. The seat did leave me "saddle sore", but is no different than any other spinning bike you'd find at the gym. Just like when I first became addicted to spinning I gave myself a few days to get over the initial soreness and worked through the leftovers. After a couple weeks it went away. If you have super strong legs to begin with, this bike may be a little easier for you. The only reason I did'nt give it 5 stars is this: especially with higher resistance the magnet doesn't work as well against your weight when you stand up to pedal, it kind of "slips" a little faster halfway through the rotation. Controllable if you concentrate on it, but distracting because you have to concentrate on it. Otherwise this bike was a great buy for the money.

  • Nice bike
    Verified Purchase

    I had ridden a stationary bike over 150,000 miles. All it's replacements lasted short time. So I picked this hoping it would be a good long lasting bike. So far it appears to be just that. Very well constructed of solid steel. Wad happy with how quiet it is. I did buy a new seat that is wider and softer. Overall very pleased. My sister says it looks just like those at her fitness center for spin classes.

  • good bang for the buck
    Verified Purchase

    Very good purchase for the money. Very smooth and quiet. The magnetic resistance makes it very easy to maximize your workout. The only two things that I would change would be adding a water bottle holder (It doesn't have one) and a transitional resistance change lever instead of a detent one.

  • great bike but...
    Verified Purchase

    Awesome bike. I'm 5'4" took me 35 min to put together. i was going slow. the bike is very very quiet. i mean I could barely hear it over the TV. perfect! Sturdy. I'm not a major spinner, but I don't think i'll ever use the lower tension settings, so I feel like i may not get the best use of this bike longer term...but only time can tell for that comment. The only that's the seat of a road bike...tiny and really hard....i actually had to wear my padded bike shorts...if you're not used to long road bike rides, you'll probably want a new seat.

  • Great bike for the $$
    Verified Purchase

    I'm used to using the startrac spin cycle at the gym. I purchased this because my gym was up to an hour and a half wait time for spin class. This bike is very comparable to that modal. The only thing I wish it had was an emergency brake but hey $$ vs $1200 I say ** the brake. It's also cheaper then ten months at my gym and I don't have to wait. I will say however that the height is good for me at 5'5" but for my husband at 6'2" it is a little small but still do-able. I would recommend this to anyone into spinning because it really is a good bike and not a huge impact on a tight budget.
