  1. Tom Frost- be glad they made it right. It is complaints like this- ungratefulness that make companies not want to help others. I’m on here trying to get an honest review on performance of the bike. You have not submitted a review. Just an issue on craftsmanship. Please keep to the subject. Write to the company on other matters.

  2. Granted, I have only been using my Flex Bike Ultra about 10 days, riding 10 or 15 miles a day, but I am skeptical of reviewers who say it is flimsy, has no instructions etc. Mine, ordered on QVC, had extremely detailed assembly instructions and comments on use. It is extremely solid and much sturdier than I expected, not plastic but very heavy solid metal. I do not see how the pedals could break after a couple of uses, unless—(1) the user ignored the specific warning to be mindful of attaching the RIGHT pedal to the righthand side of the bike, and the LEFT pedal to the lefthand side of the bike. The pedals are clearly marked “R” and “L.” Or (2) the user did not correctly screw the pedal onto the bolt and tighten sufficiently with the supplied wrench. The pedals are a very sturdy rigid plastic.
    I do agree the seat is too hard; however there are creative remedies. I folded a yard square piece of 1/4″- to -1/2″- thick quilt batting to lay on the seat and it can be positioned to cushion my thighs. It stays in place with no problem and works fine. I got the bike to in order turn my TV watching to better use, and binged on 3 episodes of The Last Ship consecutively without getting off the bike, and the seat was fine.
    I have also seen reviewers elsewhere say assembly was an easy 15 minute snap. Well, I’m 74, my late husband was an engineer who did all our assembly projects so I’m inexperienced at bike assembly. It took me a whole lot longer alone to get it done. I totally did not expect to have to put in that much effort. I do have essential tremor which is a factor, but the videos showing a 3-minute quick screw on 4 items are just a tiny bit misleading.
    I do think it helps in the use of the bike to be experienced in cardio workouts; I, too, find that the readout is not always spot-on. I spent years jogging, weight training and riding a stationary bike, so I have no problem managing intensity on this one, as the pulse readouts are good enough to pick you rate of effort and maintain it. I totally like it so far plus the QVC deal was super so I am a fan. 4-stars so far.

  3. It came with the smokey glass broken, I called to tell them and they sent me a hole new frame which is great, but now I have a second heavy frame and if I want I have to change everything which is a pain in the butt. I would need to buy seat,legs, computer, screws, everything to make any sense in having two frames. All,I wanted was the smokey glass, now I have a pain.
