Review: Bought to use with Peloton app - **notes on BANGING fix** inside - If you've had the BANGING issue with this bike, skip to the end for notes on my fix *********************************** Initially I had looked at buying the Peloton bike because of their really great app but ultimately decided it was not worth the investment considering spinning was completely new to me. My intention was to use this bike in conjunction with the Peloton app ($12/mo). So far I am very satisfied with my purchase. Delivery - I paid just under $300 for the bike which included shipping. Which is really unbelievable in and of itself. I'm not sure how the UPS guy even got it up the stairs to our landing because the box weighed over 120 pounds. This bike is *very* sturdy. My first concern was that for $300 you would get a rickety piece of garbage. Not the case. Peloton charges $250 just for shipping. Assembly - honestly, the actual assembly part took about ten minutes. But it took 10 minutes to get the box into the basement, 15 minutes to unpack the box and unwrap all the parts and another 5 to sort of gather everything together. There are very few actual pieces, like I said, the bike is very sturdy when put together. "Add ons" / changes - I made a few minor additions to the bike to improve the use. 1 - Added a pair of Shimano SPD pedals ($35). These are fantastic pedals, I *highly* recommend them and they work great on this bike. Took only a few minutes to swap out. So far zero issues with the pedals. Please not if you have never used clip-in pedals before, you will need bike shoes with SPD cleats on them to use. https://www.desertcart.com/gp/product/B003ZMDK5C 2 - Simple ipad holder for the handlebars ($20). I have a beat up, cracked-up old ipad4 that I planned to use on the bike and this clip works perfectly. https://www.desertcart.com/gp/product/B00D5YTO5K 3 - Bike mat ($30) - perfect size, seems to work great so far. Its a mat, nothing fancy. https://www.desertcart.com/gp/product/B001THTUAO 4 - Wireless computer from spinning.com ($65) - I tried two of the Cateye models and just did not like how small they were and one I could not get to work with the spin bike. The spinning.com computers are made to work with their brand spin bikes but seems to work great with this model. Look I am not an engineer, I'm not going to guarantee that these are insanely accurate and are really only made for their brand bikes - but its worked fine so far. I was most interested in something that was wireless, would display time/cadence at the same time and that was easy to read. So I spent $150 or so on other options and am completely happy right now with my setup. ***Notes on use with the Peloton app*** - As I said, I bought this bike specifically to use with the Peloton app. I am very impressed with the app so far. They have dozens of live classes every day or thousands of on demand ones. The app has a pretty simple filter that allows you to search/sort by class type, time, instructor etc. I wish there were a couple of minor tweaks - like letting you save your favorite rides into some kind of favorites menu - but so far I am very happy. The ipad version of the app is $12/month whereas if you have the Peleton bike they charge you $40/month. Even at that price, IMO, its worth it since I have been using it every day. Spin studios in the DC area can run upwards of $175-200/month for unlimited rides. ***Notes on FIXES or things that might break*** - As has been noted in other reviews there seem to be a couple of quality control issues, both of which I ran into. 1 - Squeaky resistance pad - Definitely happened to me over the first week. I used it every day and it seemed to get worse. I bought a $7 can of liquid graphite spray off desertcart and I gave it a few shots, it cleared right up. I could see just giving it a shot every couple weeks. Nothing major here, very easy fix. 2 - That BANGING or knocking on every peddle stroke. - If you've had it, you know what I'm talking about. It sounds like the bike is broken and goes BANG BANG BANG on each peddle stroke. I emailed the company and they sent me a PDF with pictures about making some adjustments to the belt with the two adjustment screws on the front. I spent @ 20 minutes screwing around with it and eventually it did stop. It was a pain in the neck and very annoying to have to deal with but it did finally stop. - Take the belt cover off - screws on the two sides and bottom - take the big side nuts off from the fork - adjust the screws I circled in yellow. Experimentation and patience required! Look, this bike cost $300 shipped. For that price, I had a reasonable expectation that the bike would not be perfect and would probably need some adjustments. If I wanted to buy the $2000 bike with $250 shipping charge, I would certainly have expected a higher level of quality. But for the cost I am very happy with my purchase.
Review: Fantastic bike, great service, happy customer - 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.

A: Thank you for your question. You can absolutely use seat covers on the Indoor Cycling Exercise Bike SF-B1002.

**Q: Hi, i am 5'-2", i just want to know if it is adjustable to the extent that i can ride it confortably? I have to make a deicion to buy it quickly. Than**
A: When it comes to bikes, your overall height is not as important as your inseam. Please feel free to copy and paste the link below on how to find your inseam. If your inseam fits within the inseam adjustment of 31 inches to 42 inches, the Indoor Cycling Exercise Bike SF-B1002 should fit just fine.

**Q: Anyone that has owned this bike for over a year, do you still love it?**
A: I've used it regularly for over two years. I ride hard and it is heavy duty and tough. Keep the leather pad oiled.
The pedals are the weak link. I replaced mine with Shimano clip ins. We'll worth the upgrade. Btw, i think the pedals are all crappy on these Chinese bikes.

### ⭐⭐⭐⭐ Very good, but has a near fatal flaw.
*by T***A on July 30, 2016*

I really wanted to give this 5 stars, but I can't for a couple reasons. I'd really rate this like a 3.75 star. This bike is sturdy and well put together. Easy to assemble, and for the most part rides like a dream. It's fairly quiet due to the belt drive, and the adjustments for the saddle and handlebars are very good - but not great. (Being shorter, I would prefer a bit more range of adjustment in both). The near fatal flaw in this bike is the belt adjustment. Holy cow is it aggravating. It must be how the belt works with the flywheel. The tighten/loosen adjustment is ALL over the place. When you are in the middle of a ride and want to adjust looser, you turn to minus, and it might just get TIGHTER for a bit. And vice-versa. Sometimes turning it seems to have zero effect. Then you wait, and turn it more, and then it has too much effect. My guess is that the friction with the flywheel has different effects depending on how tight it is, and how hot it is. This makes mid-ride adjustments aggravating. It's a near fatal flaw in what is otherwise a very enjoyable bike. So be aware if you get this, you are going to have to fiddle a lot with it during the ride. Sometimes adjusting the opposite way to get the results you need. Sometimes adjusting both ways until you can get it where you want. And there's no settings view for the adjustment. The bike can't remember a setting. It's all very arbitrary. I guess for the price, this is what you get. I will also say the seat is very uncomfortable. Trying to find a solution for that. Bottom line is I would recommend this bike if you are on a budget like me. It IS working for me as a cardio workout. It's just that the experience could be better.
