Amazing bike at current prices
This bike is an amazing value for current prices under $300. Its quality is on par with bikes over twice that price. Ten years ago when I was shopping for an indoor cycle I tried bikes close to $1,000 that weren’t this good.Quality is great, and while it is approaching commercial grade, it is still consumer grade. The frame is very stable, handlebars feel similar to commercial bikes, and the drive train is smooth with a great feel of momentum in the balanced flywheel. Magnetic resistance is smooth and maximum resistance is quite high, ensuring a full usable range of resistance for most people. The Q-factor (distance between pedals) is kind of high at 203mm, but similar to a Keiser.Despite all the positives, things like the bottom bracket (the crank with the pedals), and probably the belt, are clearly a consumer grade items and probably would be the component most likely to fail. I have no idea what long term durability is, but if a failure occurs on a spin bike, those are usually the most common components affected. The plastic pieces on the bike are lower grade material, but work fine and probably keep cost down. Overall, it is a very sturdy bike where it needs to be.I see complains about the saddle and pedals in some reviews. Just assume you won’t like these and will have to replace them, whatever bike you buy. These components are user replaceable and what comes with the bikes is usually cheap junk. One size saddles do not fit all and many people dislike what comes with a bike no matter what style is used. Even my $1,500 Schwinn commercial indoor cycle came with a seat that cost $14 for an exact replacement, and pedals that started clicking after a month. If you don’t like the saddle, go to your local store and get a comfortable replacement. It uses the same type of saddle that a normal bike uses. Don’t bother with gel covers that cost almost as much, or putting up with it just because it came with the bike. Saddles and pedals are replaceable for a reason.With that said, I actually like the saddle on the Sunny. Good support for sit bones like a good bike saddle, though this one is clearly an inexpensive model. The pedals are still going strong after three months of daily use, something I didn’t expect.Adjustability is average but fine. Spring pins are used to adjust the handlebar and seat towers, but only a one inch increments. However, this type of system won’t slip during a ride which is important. The seat has micro-adjustments fore and aft, but the handlebars don’t. It would be nice to have that, but for this price you can’t have everything.The handlebars did start to wobble a bit, but I simply wedged a couple clothing price tags between the frame and tower and now it is fine. This is a common problem with many spin bikes where the plastic sleeves wearing out.At full list prices there are probably better options out there, but under $300 this is a definite winner.

Decent bike for what you need
This is my first indoor bike so not really sure what I was expecting but I’ve had for 3 weeks now and enjoying it a lot. I do a lot of outdoor biking but now that winter is here this will be perfect for getting some riding in!Cons: the seat is UNCOMFORTABLE!! a few people mentioned in their reviews that the seat was permanent and could not be changed- IT CAN ACTUALLY!!!! I bought a comfy wide seat from Walmart and was able to change it. any standard bike seat should fit, you just need a wrench!And lastly, the SunnyFit App is great! Tons of workout videos from cycling to yoga and even outdoor audio to listen to on your walks.

Great home trainer / spin bike
I’m recovering from a recent knee injury. After much comparison and deliberation I settled on the Sunny AeroPro for my recommended indoor cycling.The frame dimensions, multi-position handlebar, 175 mm crank arms, 44 pound flywheel, and magnetic resistance provide me with a normal cycling position, close to outdoor feel, and quiet training. I haven’t measured the Q-factor but it is on the wide side; not uncommon for a belt drive indoor bike. I’ve replaced the supplied seat with one that’s narrower and firmer; what works for me. The supplied pedals don’t spin very freely and I’ll eventually replace those too. I’m very happy with this indoor bike; it’s a great value!If you are on the smaller side you should probably pay attention to the frame dimensions and crank length. I know some Sunny models have smaller frames. The dimensions can be found on their website. I was surprised to find that my bike was delivered with 175 mm crank arms, that’s what I use. But you might want 165’s or 170’s. The only crank arm measurement I find on Sunny’s website is for replacements with an overall length of 8 inches, no center to center listed. I measure the crank arms I received as 7.75 inches in overall length and 175 mm center to center.The AeroPro doesn’t include any onboard computer and doesn’t connect to the Sunny Fitness app. I added a Moofit cadence sensor to the left crank arm which connects to the MyCadence app on Android. My Polar H9 heart rate sensor likewise connects with the Polar Beat app. Using split screen I see cadence in the top 1/4 screen, heart rate and time in the bottom 3/4. That’s all I need.Now about shipping: Where we live in rural New Hampshire FedEx is the worst shipper, by far. Earlier this winter they left a $300 snow tire next to someone else’s mailbox three plus miles away from our house and documented it with a delivery picture! I ordered this bike on February 3, FedEx picked it up on the 5th, and finally delivered it on the 19th after repeatedly saying it could not be delivered, my calling, and their sending it between two delivery centers and into Connecticut! The box wasn’t crushed but looked like it had done several conveyor belt marathons. Sure enough the plastic chain/belt-guard was cracked in a couple of places, and the plastic bushing that sits in the frame where the handlebars insert was damaged. Thankfully the seller has a simple process to get damaged parts replaced and they sent them UPS!I’m very happy with this bike!

I’m impressed with this bike for the price! I was a regular spinner at a studio but they shut down due to covid. I was used to heavy tension, comfort & a stable bike. I didn’t want to spend the money on a pelaton so after researching bikes comparable to what I was used to, this bike beat others by far. The flywheel is 44lbs so there’s enough tension for a great workout. It was easy enough to assemble, just took some time (~2 hours). It’s stable, quiet and easy to adjust for perfect body alignment. I had it in 5 days of ordering!

So I am in love with this bike. My husband has done lots of research and this one was the winner for us. Very strong, noise free, great power I just wish there was a way to be able to adjust the handles. Been using it for couple of months and it’s great.
Smart shopper –
Love this bike! Well built, noiseless, smooth resistance

I use this for my peloton classes. On my third week so far and it’s a great quality bike, quiet and easy to store away.
