    • great little bike

      Just got this today, within a couple days of ordering it. It was very easy to put together. The mfg thoughtfully puts all the bolts, washers, & other parts on where they should be, rather than loose in a parts box. This is genius. But apparently I'm not, because I spent an hour looking for the saddle stem, and thought it was either missing or that I'd thrown away. Turns out it was already inside the stem, where it should be - I just had to pull it out! Duh. The bike is virtually silent & smooth. I'm 5'6' and the maximum height setting for the seat is just barely right for me, so taller people beware. Otherwise, a great deal.

    • Sunny SF-B910 Magnetic Upright Bike

      It is very solid material. The instruction is very clear. It took around 1 hr to assemble it without any problem. It is kind of weird to raise the level as opposition to the direction sign, Besides that, it is a great machine. I increase the level accordingly to my practice and it does help a lot.

    • great buy

      Absolutley great buy!!. First purchase from Overstock but won't be the last, fast cheap shipping, product received in 5 business days. did a lot of reasearch before deciding on this model based on both price and small size. This product exceeded my expectations!!!. First of all it was so easy to put together as the manufacturer places all nuts and bolts needed in a baggie clearly labeled step 1 step 2 etc... Assembly took about 40 minutes. Bike is compact yet sturdy and their is a clear distinction between each of the 8 resistance levels. I have been using bike for 30 minutes each day on level 1 and definitely break a sweat!!

    • Simple and easy to assemble

      This is a very simple exercise bike with manual adjustment and no programs like some models. It fits my needs however, and was surprisingly easy to assemble. The tension seems to be strong enough to provide a good workout. Only downside could be that the seat adjustment is limited. I'm '5"10 and have it pretty much set as high as it can go, so could be an issue for someone taller. Overall, a nice bike for the price if you just want a simple home workout machine.

    • Great bike for the price!

      Very happy with my purchase. The display did not work at first but by opening the unit and tightening the circuit board screws everything works fine now. The seat is a little hard but no unbearable.

    • The best deal

      As long as you have a good friend who knows how to put things together, this is the best buy I've ever made on Overstock! It has provided me with instant exercise for my bad knee, cardiac and aerobic. I listen to music, pedal as fast or as slow as I want, and burn calories. Since I can't walk at the moment I can just hop on the bike and get the exercise I need. I'm grateful to Overstock!

    • Not a fan of this product.

      The seat of this bike is ridiculously hard and uncomfortable! The digital screen for calories burned, mileage, etc is a joke. You have to know what sequence to press certain buttons to get it. It doesn't automatically shows up when you turn it on, and since I lost the directions I haven't been able to use the screen. I wish I would've known how cheaply this bike was made. I would've spent a little more for a better quality bike but thought for what I was going to use it for would be sufficient...as long I saw how many miles I biked and how many calories I had burned, which I cannot see now. Very disappointing. :(

    • GOOD

      IT IS KIND OF HEAVY WHEN YOU START MOVING, BUT IT WORKS PERFECTLY IF YOU JUST NEED TO EXCERCISE.

    • Great Indoor Bike, Just Don't Pedal Backwards

      Overall, this is the best indoor bike for the price. Extremely simple to put together yourself. Has a timer, calorie counter, and distance tracker. Seat is uncomfortable after 20min, but most of them are. Other things I like about the bike: The iPad case I have fits perfectly over the timer display with the elastic band securing it like a tent so I can watch video, listen to music, surf the internet while I pedal. It's quiet. The straps on the pedals are adjustable to your foot size. I can lift up the front and easily roll it around the living area, it's not heavy. It has a heart rate sensor in the handles. Seat height is adjustable. I've had the product for over a month now- the only problem I had was that the internal resistance band fell off after 8 days of consecutive use. I thought it was broken, because it felt stuck and loose. But I took the entire bike apart, popped off the plastic frame- somewhat tricky ordeal- and watched a video on how to spin the resistance band back onto the turning wheel. I discovered that the design of the wheels and the ridges in the rubber band would shift out of place if you pedal backwards a few times. DO NOT PEDAL BACKWARDS. Get off the bike if you need to stretch. This doesn't happen to the bikes at the gym. Ever since I fixed it, I can now feel the different resistance levels. Before, when it arrived Level 2 felt like Level 8. It may have been defective, but in the end, I am extremely happy with the product.

    • Great purchase

      We are very happy with this cycle...very quiet, nice ride. Casing was cracked when we received it, but manufacturer sent new one that we replaced quite easily. Seat is not adjustable front to back, only up and down, but I can live with that. Ou will actually use this for exercise, not just to nab No your clothes on!

    Guidelines
    • I am 5'0' tall. Will this bike work for me. davidd

      Guidelines
      • Thank you for your question. Yes David, this should work for you. The seat is adjustable, so you can adjust it to fit your height. Please let me know if you have any further questions, and thank you for shopping with us! Have a great day! -Rachel

      • It should work for you. However, the screen to show you the mileage and calories burned is not an easy read. You have to press buttons a certain way and since I had lost the directions, I haven't been able to see the information. Also, the seat is extremely hard and uncomfortable.

    • What are the exact dimensions of this bike? I see none listed in the description.

      Guidelines
      • Thanks for your interest, this bikes assembled dimensions: 34.5 inches L x 23 inches W x 50.5 inches H.

    • Are there instructions on how to use the computer?

      Guidelines
      • There is a one page, very limited explanation on how to program the bike. Not very clear and difficult to figure out. I use computers every day, so I am not totally ignorant, but these instructions were not the best. I still like the bike.

    • I am 5'10". My wife is 5'4". We are replacing a bike with over 2000 miles on it. Do you think this bike will fit both of us? I see reviews that say 5'6" or 5'7" is max?

      Guidelines
      • According to reviews posted by customers who have purchased this product, this bike may not work well for people taller than 5 feet 6 inches.

    • How heavy is it please? If you are 5'1" - does seat go low enough? are handles then too high?

      Guidelines
      • Bike weighs 52-53 pounds. This is a small bike and you should fit but it does depend on arm length. Model SF-RB801 will fit you for sure but I don't have the product number.

    • I just put the bike together and I think the resistance at level 1 feels very hard- and I know from other bikes that it should be easy. In fact, when bikes start to feel this way- they are done in my experience of about 6 bikes over the past 2 decades. Is this hardness something that will improve?

      Guidelines
      • Absolutely. The resistance on the lowest level should not be that high. We would recommend double checking all settings and going through the manual as well to see what the lowest setting entails in regards to resistance.

    • can seat be moved up and down or replaced? Handle bar position adjustable? What is distance between front band back feet on the floor? Hart to assemble? Thanks.

      Guidelines
      • Seat post can be moved up and down. Actual seat angle cannot be adjusted (like a spin bike would be able to do). Seat can be replaced; with the same exact seat. This does not have a spin bike seat or set up.
