  • 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.

    • Please tell us about the quality of the product. Very good

  • 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.

    • How accurate was the sizing? very accurate

  • 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!

    The Sunny Mag bike was easily put together, works well, as light as a feather, and fun as hell.

    • How accurate was the sizing? The sizing is probably better for someone under 6 feet tall

    jlomb007 from Chicago, Illlinois,

  • just what I needed

    I am recovering from a broken ankle and wanted something that would allow me to exercise without putting stain on my ankle. It's a great size, I can easily move it from the corner to in front of the TV. I find it to be comfortable and very quite, I did purchase the gel seat cover which I think was a good choice. I was able to put it together in about an hour (that was while watching a movie and talking on the phone). I used my own wrench which worked better than the one included with the bike. And since I like sitting up straight I turned the handle bars around so that they point towards the seat instead of away (as in the instructions). It feels smooth while pedaling and overall feels sturdy. It works just fine for my fitness level. If you are a hard core biker and looking for a strenuous workout, you may want to pay more money.

    cperspective from Washington,

  • A good all-around value.

    This is a good basic stationary bike. It is super quiet and very compact. The only draw backs were: the seat is shaped to make sitting upright more comfortable than leaning in to the handle bars. This makes it good for reading or watching TV. Some one over five foot eight might have an issue with the distance between the seat and the peddles but I got used to the short length.

    • How accurate was the sizing? The size description matched expectations.
    • Please tell us about the quality of the product. This is a light weight, easy to assemble basic stationary bike. It is very quiet,

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. joannerunyan on Feb 9, 2013
 
 

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? johnnyredd on Aug 1, 2012

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. overstockcustomercare1 on Jun 12, 2012
 
 

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?  on May 4, 2012

Answer This Question

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. overstockcustomercare1 on May 9, 2012
 
 

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. mamatildarjorie on Mar 10, 2012

Answer This Question

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. overstockcustomercare1 on Mar 13, 2012
