Style: Classic 49LB Flywheel
Delivered quickly and well packed. Exterior or package showed evidence of a drop on one corner, but only apparent damage was a significantly deformed packing strut (intended to be discarded). Instructions for assembly and adjustment were complete and useful. Insertion and adjustment of seat and handlebar columns required dead-blow hammer force, but as adjusted are completely stable -- no wobble or loosening, Based on other review comments, I replaced the supplied saddle with one I knew to be comfortable for me, along with the supplied pedals with clipless pedals. I also installed standard wired bike computers, using alternate spoke magnets and sensor attachment methods (double sided tape, longer zip ties and wood spacers). Time, cadence, speed, distance and other statistics are now available. As I have only had the unit a short time, with about 15 hours of use, long term durability is unknown. Operation has been excellent. Entire unit is rock solid, operation is virtually silent, and resistance device works well. REVIEW UPDATE - after four months use (approx. 100 hours/2500 odometer Kilometers). The five star rating remains unchanged. Details on bike computer installation: Most bike computers are based on a clock, micro-switch to sense magnet attached wheel & or pedal crank, and memory of a manually input wheel circumference) with statistics reported calculated from these three elements, As I wished to have continuous display of speed and and pedal rpm as well their session averages I chose to use two separate single sensor computers. Wheel circumference setting input to yield speed was the measured flywheel circumference, 1460 mm (57.5 inches) about the same as for a 409 bike tire size. Wheel circumference setting on input to yield pedal revolutions was 167 mm (correct conversion factor is actually 1667 mm, but because of specific input limits of computer used, the lower amount was used. Resulting "speed" mode display is 1/10 or actual crank revolutions per minute, with two displayed digits after the decimal point (for example, 100 RPM is displayed as speed of 10.00). The actual computers selected were Sunding model SD 558A because of display size and price (actually paid less than $5 for both, but currently available on internet for about $12 a piece). Their sensors are wired. Virtually any available bike computer could be substituted, but specific mounting and setting procedures might be required. The computers with their display screens mount on the center of the handlebar using the supplied mounts and zip ties. Because of the cycle frame configuration, sensor mounts required fabricated shims and longer 11 inch zip ties (the originally used tape eventually lost its grip). The shim for the RPM sensor is approximately 1/4 " X 4 1/2" x 2" with 2 drilled holes in one end to secure the sensor to the shim with supplied zip ties, and two 11" zip ties around the upper belt guard and shim secured it in place . 3 11" zip ties secured the sensor wire to the frame between the sensor and its display head. I replaced the supplied wheel magnet with a .75" round ceramic magnet attached with only its own force to the right pedal crank arm at the inside of the pedal. The shim for the speed sensor is approximately 1 3/8" X 5/8" X 4" 2 holes drilled in one of the 1 3/8" sides to secure 11" zip ties to the left front bike fork and 2 holes opposite them to secure the sensor with two supplied zip ties. An additional 2 11" zip ties secured the speed sensor wires to the bike frame between the sensor and its display head. I replaced the supplied wheel magnet with a .75" round ceramic magnet attached with only its own attraction to the flywheel, just below its rim. The resistance device works well, with proportionate increases in resistance with knob turns, no noise or vibration and no odor. I did spray the resistance pad with silicone lubricant before use and again after about two months use when a minor vibration had developed, I assume this will be a normal maintenance requirement, a two second burden I can live with. I contacted Sunny Sports and Fitness at their customer service web address to determine where cycle model specific parts could be obtained. A response arrived the same day that they could supply my needs (a resistance pad assembly and seat tube sleeve plastic sleeve). cost incl. postage was $12.50, which I consider a bargain. The water bottle holder presented two problems to me. In its original position, my right knee would occasionally bump the holder as I performed jumps (I am not yet as smooth at these as I should be). Relocating the holder to the front of the fork frame and reattaching with 2 11" zip ties solved this issue. The 28 oz. water bottle I use did not slide into the holder easily. Slight bending of the top of the holder front and rear wires improved the bottle fit.

Style: Classic 49LB Flywheel
This Sunny spin bike is very similar to the bikes we had at the gym when I first started spin classes there. 12 years ago. They upgraded to some more glitzy bikes, but I continued to just monitor my heart rate with a chest strap and cell phone app. Which is my go-to with the Sunny bike at home. If I want to participate in a group session on the bike, there are plenty available online and it is easy to find a way to attach your phone to the bike. Now I just put on the radio and watch my heart rate go up. And I can hear the radio better now since this bike is so quiet (I had been using a cyclops wind trainer before which was fine, a little noisy, and not the level of workout that this bike provides) Personally , I have no need for anything fancier than the heart rate monitor/fitness app, but there are a lot of reviewers that purchased add-ons that provide a 'Peloton-esque' experience. Even with the expense of the add-ons, you can't beat the price and quality of this bike. A lot of reviews and questions I read before purchasing this bike indicated that some folks are a little naive about what is required to use and maintain a good spin bike. When I attended spin classes at the local gym the bikes developed the kind of issues reviewers here are complaining about. So the bikes had to go to maintenance and were returned. They were used a LOT, so not surprise there. Same goes for this bike, if you purchase and use it a lot. However, if you set up and maintain it properly, including fixing it when it thumps or creaks, it will pay you back in a great spin. Sunny has videos and documents online to help you. My bike was a little thumpy at first. Usually a pedal problem. You can just tighten up the pedals more, but I recommend using a threadlocker on the threads when you screw the pedals in place. I used harborfreight semi-permanent threadlock. Another reviewer used loctite. I also changed out my pedals to use shimano pedals that allow me to use either clip or clipless. If you prefer clipless, you might go that route. Either way, tightening the pedals with threadlock eliminated the thump immediately. I have not had to tighten the crank, but I see this as something that may be necessary down the line. There are videos on doing that with bikes in general online. The other item you really need to check when you first set up your bike is the leather brake pad. It will likely need to be lubricated. Some folks complained that the bike smelled like something burning. My guess is that they never lubricated the brake pad. If you bike is new, this is as simple as putting a few drops of 3 in 1 oil on the flywheel where the brake rests with light resistance, rotating the wheel and letting the oil soak in. The pad will get considerably darker in color. If you have been riding it a while, you might need to pull the pad gizmo off and rough it up a bit for the oil to absorb. That requires removing one screw. Not rocket science. One of the beauties of this spin bike is that its design is relatively simple - not all those bells and whistles that potentially go bad. That also makes the great price point of this sturdy piece of equipment, especially the heavy flywheel that you wouldn't find in an inexpensive bike and that makes this an amazing spin bike.
