We've had this bike for 3 weeks and love it! Both my wife (5'5") and I (6'0") use it, and adjusting the settings is simple. We bought a new gel seat for it b/c she said the seat was hurting her. I thought the seat was fine and after a few days of using the bike, my butt "got used" to the seat and stopped hurting, so before you cave into buying a new seat, ride through the pain for a few days and see. We do not have the high pitched sound problem created by the brake pads that some people were talking about. The bike is very sturdy overall and has adjustable feet so that you can make sure all 4 feet touch the ground so the bike does not rock back and forth. The tension adjustment knob is more sensitive than on the bikes I've used at the gym; at the gym, a lot of the knob turning is a quarter turn to a full turn. On this bike, all of my knob turns are within about a 1/2 turn range of each other as a full turn will all but stop you dead in your tracks. Not a complaint by any means, just an observation, and possibly a plus for some people b/c an 1/8 turn is quick and easy to do and will crank up/down the resistance noticeably. For cage pedals, the included pedals are actually decent, though annoying to adjust the strap on. We are going to swap them out for Look-style clip in pedals though b/c clip in pedals make your ride so much smoother and give you a better workout. Assembly was beyond simple. I don't think there is anyway it could take more than 30 minutes for anyone to do. The provided tool do the job well. At just ~$240 (look for overstock coupons before you buy!!! I got $25 off!), this is a huge bargain and less than 5 months of gym membership. We are probably going to cancel my wife's gym membership, meaning that after 5 months, this bike is actually saving us money!
My initial experience with the Sunny Pro was pretty much the same as described in previous reviews: delivery within a week, cumbersome packaging, easy set up (about 30 minutes) and so on. I have a set of clip-in pedals already so I wasn't disappointed with the pedals (and, for the record, the strap-pedals are probably suitable for many riders). So things looked ready to go . . . And then I tried riding the bike and encountered a serious problem. Whenever I tried to increase the resistance to even a mildly strenuous level the flywheel squealed terribly; worse yet, even when I tried to continue pedaling over the noise, it would simply lock up. I think this is because the bike uses cantilevers and pads with dense fabric instead of magnetic resistance. In other words, when one turns the resistance knob the pads press against the flywheel, sort of like brake pads on a bike. I believe that the friction between the flywheel caused both the squealing and vibration that caused the resistance knob to rattle, thereby tightening the pads inadvertently. Needless to say, this was a source of great frustration and I tried all sorts of adjustments to the resistance knob, the cantilevers, and so on with no luck. I was VERY disappointed by the bike because I thought it was basically going to end up as a very expensive clothes horse. But I finally decided to try smearing each side of the rim of the flywheel with lubricant to reduce friction, not knowing what effect it would have on the material that covers the resistance pads. Long story short, this seems to have done the trick and now the bike works beautifully. I'm pretty active---mountain biking, in-line skating, martial arts---and it looks like the Sunny Pro will provide strenuous indoor workouts for a long time to come. I really do think it's on par with much more expensive machines. Time will tell. For now, though, I’m giving it four stars because of the frustration I experienced initially. The solution I came upon may seem pretty obvious but it wasn’t included in the directions or in other posts so I thought I would share it. It’s made the bike functional instead of completely useless.
I would give the bike five stars if it could accommodate the full stretch of my legs. But it can't, and I'm not tall (5'9"). I would heartily recommend the bike for persons under 5'8" or, even more so, for persons under 5'7" in height. Still, I can get a good workout if I sit on a couple of thick cushions that I add atop the seat. The pedal resistance adjusts from easy to quite strong, stronger than I can pedal for more than a few minutes. It is possible to pedal either forward or backward or to coast and take a breather. The performance monitor either scans pulse, speed distance, time, and calories burned or, if I choose, show any one of these constantly. The display is large and distinct, though I do have to lean forward a bit to read it. The bike is stable in use. Its lightweight and small hind rollers allow moving it easily in order to position it where I want. Its 38.5" length takes up minimal space. The bike comes unassembled, but assembling it is not complicated and takes only about an hour or so. Assembly instructions are about as clear as such instructions come. I recommend following these instructions strictly in the given sequence. It is especially important to pay close attention to instructions for screwing in the pedals. The bolt for the left pedal threads in the opposite direction than the bolt for the right pedal. The pedals are clearly labeled L and R. Incorrectly screwing in the pedals is the one thing in assembling the bike that can do serious damage to it. The most vexing step in assembling the bike is the very last one: attaching the rubber foot straps to the pedals. This requires pulling/stretching the foot straps a little in order to snap them into place. A gently tug with a pair of pliers (the one tool not included in the shipping box) can help.
I got this bike after much research, needing to replace the ******** I had for 12 years and which was just worn out. The negative reviews in the past couple of years for the ******** bikes convinced me that ******** was doing the corporate cost-containment thing and going cheap with their quality, and I can't afford to spend money on stuff that breaks down. This bike arrived when promised. The carton was a bit beat up, but everything was there and there was no damage to the parts. Careful when assembling this bike - the parts list shows many nuts, washers, and bolts which are already attached to the bike, which I didn't spot; so I thought a couple bags of parts were missing from the box until customer service told me they would be attached to the bike already. Assembly took 90 easy minutes, and everything went well. The bike is solid and utilitarian - it has good resistance, smooth operation, noticeable changes in the 24 levels of resistance (once you get past the first 4 or 5 levels, which all seemed to offer the same low level of resistance). The biggest surprise was the pulse monitor - this one is actually accurate. I am skeptical of heart rate monitors on exercise equipment, as they seem to have such wild ranges; but the SB2.5 was dialed in right at the same pulse rate that my 'thumb' monitor showed. And, it does have the connection for a chest strap monitor if you want to buy one of those. After a couple days of use, I had to re-tighten the frame bolts securing the front and back frames, as they had worked loose. If that continues, I'll just replace the bolts with longer ones that are secured by lock nuts. The electronics worked fine, even though there is an anomaly in connecting the readout wire harness with the base harness. One pair of wires is brown-yellow; the other connecting pair of wires is brown - brown/white; so it is a bit of a guess as to how to connect them. I was fortunate in that I guessed right the first time. If you guess wrong in connecting this basic wiring harness, you'll just have to remove a few bolts holding the display on, and change the connection. This bike has more of a recumbent position than my nautilus, which I like. It's very easy to reach 140 heart rate, and the display shows all measurements at once - speed, calories, distance, time, pulse. resistance level. I don't use the programs - just set it on manual, and increase the resistance levels at different intervals. This bike seems to be a good, functional, solid recumbent bike.
