Ultrasport F-Bike Folding Exercise Bike - Extra Silent with Relax Foam Seat and LCD Display - Exercise Bikes for Home Use, Exercise Bike Foldable, Indoor Bike, Stationary Bike

Edit:Had this bike for 3 years now and its done 2000km, based on its built in computer. It started to make a knocking noise so I checked inside (you can see inside through the top cover with a torch) and one of the two drive belts on the fly-wheels has started to fray and has split. I contacted Ultrasport and they are sending me a replacement belt, with instructions on how to replace it for free.This is outside of warranty, and they said they will do this for any bike that needs a belt replacement. That’s excellent customer service!(If you want to replace the belt yourself, there are two within the bike, and they are standard size and pretty cheap to find on eBay or elsewhere. The 230J attaches to the metal flywheel, and the 240J attaches to the larger plastic drive wheel. About £6 each.)A decent exercise bike for a good price. Easy to assemble and seems to be pretty robust, though we’ve only had it a month, so too early to tell.Until now we’d only had a small floor exercise bike - the kind that doesn’t have a seat and you place under a chair. It was pretty rubbish with practically no resistance.This proper, magnetic bike has a decent amount of resistance at level 7 and 8. It’s very subjective, though, and if you’re a keen cyclist you might disagree.For us, it’s perfect. Quite small, easy to fold up and with enough resistance to give me a decent bit of exercise after working from my home office all day.(Note that if you are under 5ft3 or so, you may struggle to reach the pedals comfortably. My wife is 5ft and I had to saw a couple of inches off the bottom of the seat post so she was at the correct height to use it when sitting. Not a big deal, easy with a hack saw and some elbow grease, and I can still use it at the higher seat settings.)

I bought this machine as it seemed good value for money. it certainly is. sturdily constructed. I weigh 161/4 stone & this is so well made that it would cope with more without a problem. seller being cautious over max weight. others have dealt with mod for saddle height & low setting for serious workout. however after 5 weeks of use at 10 mins. per day to tone myself up a bit I found that setting 8 was not challenging enough. It was to start with but I was very unfit. As soon as my leg muscle tone improved setting 8 was too easy & no way was I going to do any serious "burning".I removed the cover screws on each side of the pedal unit to reveal the same arrangement as on a cycle to adjust the brakes. If you wind back the nut on the cable to near the end of the cable cover, not the cable end, & raise the bolt on the other side of the cable head bracket this allows the magnet? to move nearer to the flywheel which increases the tension. If you hear any scraping noise you have raised it too far & need to screw it back down a bit- I suggest 1/2 turn at a time until there is no scraping sound.This is relatively easy for a DIY person & would be even easier if you removed the Right Hand Crank so the cover could be totally removed ( thus making it easier to get spanners on the nuts w/o fouling the case ). Make sure you refit the parts of the cover back together properly before doing up the screws & securely tighten the locking bolts on both cable adjusters.This adjustment has now made setting 8 setting 4/5 & setting 8 is like going up a very steep hill. just right for some serious work once I am reasonably fit. Interestingly settings 1,2,3 do not seem to be any harder so are ideal for the unfit or weaker muscled people. Of course if this adjustment is too much you can always screw the second bolt in a bit to reduce the max. setting a bit but if you find setting 5 is now hard work you know that you have 3 more settings to go as you improve your muscle tone. BUT do not over do it early on. Work up slowly.This may affect your guarantee although I don't see why & please be careful not to exceed your capabilities early on. I am 71 & very unfit but 10 mins. a day for 5 weeks has made a world of difference & I am now ready to start burning off my fat at a higher level probably setting 5/6 for the next few weeks.This is an excellent machine for the money & amazon deserve full credit for sponsoring such a machine at the price.I

I purchased this for £79.99 (free delivery) and received it within a couple of days of the purchase.It was easy to put together (from what I saw!). It doesn't make much noise (sounds like a bike outdoors in the wind), if at all. The seat is comfortable as it is wide (no need for a cover). The tension is decent given that I've only started back into my exercise routine (started tension level at 5 as lower is too easy). I can see me reaching tension 8 within a couple of months and then needing more. I saw a comment (then I researched the internet!) that I could add on leg weights Everlast Adjustable Ankle Weights - 2 x 5lb, Black to get the tension I am looking for and will probably purchase the weights above in a couple of months. It folds up decently that I can put it behind my twister chair in the corner of the living room and it not be in my way (although it stands up behind the chair... willing to live with that!). I've had it about 2 weeks, so it'll be interesting to see if it lasts more than a year. You may want to consider purchasing floor mats (York Interlocking Floor Guard) as the bike will put a dent in your carpet/could scratch your wooden floors as it is of decent weight (but not too heavy to move around the living room!). The computer is very useful in determining how far you have biked and how long it took you to bike the distance. Don't use the other features that much. It's pretty sturdy bike that doesn't feel/look like it will fall apart any time soon.Overall, great bike to purchase if you are wondering if you would actually use the bike at home. Maybe consider purchasing a different bike if you're serious about exercising on static bikes as the tension could be better.
