As good or better than assault bike classic
I used an assault bike for 2 years and owned an echo bike for 3. I like chain air bikes better for endurance and they also do hiit well. I don’t think the echo bike is well suited for long endurance for me so I sold mine. This thing seems to have the exact same drivetrain as the assault bike classic. It has more trim covers to protect it. The monitor seems to work fine; I got much better contrast on it once I put a fresh set of batteries in it. The calorie count is quite stingy. Kind of like the echo. The arm handles are nice and tight. The pedals are a little narrow and seem to be threaded non standard so I couldn’t put mtb pedals on it. Resistance feels exactly the same as the assault bike. The seat is perfect. It’s a good buy at $400. There’s plenty of other options at $670.One week use update: the bike is awesome, it got smoother as the miles went on. The pedal slips off my shoes and so I put a 9/16 mtb pedal on and it’s much better. Helped the crank Q factor narrow a little bit too which was good.

Good cardio workout not difficult to assemble
This is my second stationary bike purchase. A few years ago, I purchased a Schwinn air dyneI didn’t buy another one because of price point, and because service on the Schwinn was expensive. I decided to try the sunny stationary bike.The major differences between the two, other than cost is minimal.1. The wheel is the same size. However, the fans with the Sunny wheel are much smaller see picture. Which means less exertion is necessary. This is not to say you don’t get a good work workout. Actually, I find that I’m getting more of a cardio workout because I’m pushing harder and going faster. I also like that they have added a wind blocking guard. (Sometimes first thing in the morning I don’t want to get hit with wind..).I’ve also noticed that it’s a much quieter bike than my Schwinn. There is no tension controller, it is entirely up to you how fast and hard you want to push.2. The computer panel is functional. I’m not one of those people that uses all the programs. This one gets the job done. I use the computer panel predominantly for time and intervals.3. The sunny stationary bike is remarkably stable.I bought a mat to put under, which I highly recommend. However, there are wheels to help adjust stability in all four corners. See photo.4. The bike comes with front, moving wheels and a handle on the back for easy mobility.5. This bike was remarkably easy to put together and came with all the necessary tools, which you can save and place in your toolbox. The tools were not some cheap offshoots whereby you dispose of them after use.Overall, this is a good bike for the price, and provides me with a good cardio workout.I give this bike a 4.8 rating.

Bike n with the oldies…
This holds up under the 200 plus pound group under daily use. It is functional and of a good quality for the price.

Great purchase
Love this assault bike ! Works just as good as the more expensive ones ! Don’t waste your money on the others and buy this! Although mines arrived broken, I was given some money back as well as the break did not affect my ability to use the machine. It was a slight crack.

Great Workout especially compared to my Schwinn Airdyne 2
I also own a Schwinn Airdyne 2 and this workout is MORE difficult. The Small front fan wheel on the Schwinn doesn’t give as much resistance as the larger wheel on this (the Sunny Tornado). On the Schwinn Airdyne with a 32 minute workout I get 11 miles with an average of 69 to 70 RPM. On the Sunny Tornado, with a 32 minute workout I average 9.5 to 9.9 miles with 51 RPM. So the big fan makes this a tougher workout. Very sturdy bike. I am 6’3″, 195 lbs and this bike doesn’t wobble or show any signs of difficulty. With the Schwinn I have replaced the arm once now in the 2.5 years I’ve owned it. This purchase was originally for my wife and she quickly decided she liked the smaller Schwinn. The Schwinn is better for her as she is 5’5″. Very happy with my purchase.

Fan Bike
We had this bike for just over 3 years… used it 2-3 times a week for HIIT type training workouts. The bike developed a very bad wobble on the left side of the handle and foot pedal. Which ultimately caused the pedal to literally strip off at the bolt portion that connects to the arm of the pedal. I just tried to look on Amazon for replacement parts and I’m finding nothing.

Used this for a few weeks now and ridden quite a few KM on it, quality seems excellent and the display and controls are also great. Plenty of adjustment as well works well for my wife and myself.

Es una bicicleta excelente para hacer cardio intenso si tienes poco tiempo, realmente te lleva al límite de cardio y esfuerzo. La calidad es realmente buena, no le pide nada a las de los gimnasios y sitios de crossfit ya que su ventilador es bastante grande, es robusta y materiales de excelente calidad. Es pesada por el cuerpo metálico sin embargo es bastante fácil moverla por las ruedas delanteras incorporadas. El armado aunque parece difícil de un inicio es sencillo y muy intuitivo además de que viene bien explicado en el instructivo y no necesitas material extra ya que incluye un juego de llaves.En conclusión: me parece un producto excelente, la calidad la considero incluso mayor a su costo y esta pasando la prueba de desgaste ya que le he usado bastante y se siente igual que el primer día. Estoy bastante contento y satisfecho con la compra, la recomiendo ampliamente y volvería a comprarla, además que llego bastante rápido.

Really great mainstay for my workouts. Easy build, only took me an hour to put together and really nice and durable. The build itself is very sturdy and I have been putting some fairly intense workouts on it just to see how much it can bare. All in all good buy.

DO NOT BUY. I used this for the first time today. After 17 calories the left crank fell off. The surclip holding the bearing fell out and the whole crank fell off. I attempted to put it back together but the bearing doesn’t actually fit in far enough for the surclip to catch properly. There is nobody to contact or customer support. No way of contacting the seller.
