Incredible Value

I wrote a review on this bike, but it seems like it didn’t post. This bike is incredible. Sturdy, easy to assemble, super quiet and rides like a dream. I have wanted a spin bike for at least 6 months, but have been using a trainer. The problem was I was burning up tires and need constant tune ups. I finally decided on this one and WOW! This thing is built like a Sherman Tank and is better than the bikes at the gym. I didn’t want to spend $2000 on one of “those” bikes and I’m glad I didn’t. This one will no doubt last for years and is equal in quality. If you’re looking for exceptional quality at a lower price don’t hesitate. I’ve been riding indoor and outdoor bikes for a long time and this one is exceptional. I am one happy customer!

Solid bike! Way better than expected.

Ordered bike and even with the COVID-19 delays, it got here fast (less than 10 days). I normally ride a high end spin bike at my gym and I was amazed how this bike rode. Much more solid (I am 6'2 and 260). It does not wobble and the resistance is great. No odd catches when turning the dial. Very happy. I got the Peloton app and added a phone holder to the top so I can do spin classes at home. Also added clip pedals so I can wear my bike shoes. WAY cheaper than a Peloton bike. Super solid and a great ride. Would highly recommend.

Best bike ever

I love this bike! I’ve had it for over 2 months and use it 6 days a week. Very smooth and stable bike. I had another brand before and had nothing but problems.

Overall a good value - quiet & sturdy

I purchased this bike pre-pandemic. Overall, it's a good value. It's sturdy & quiet. I added dual-side SPD pedals, a wahoo cadence sensor, a Polar H10 heart rate strap, and my spouse made a table holder for it. I stream the peloton digital app (and the $12.95 USD a month is a fab value, too). The handlebars will wiggle forward if I'm slogging my bodyweight side-to-side. No amount of tightening makes it immovable. I do notice that if I quieten my upper body movement and don't put my upper body weight onto the bars, the handlebars won't move. I tighten the seat bolt occasionally when it starts to squeak. While it would be handy to have a 'continuous' seat height adjustment, the slotted seat height adjustment works well enough for my spouse and I. He's 5" taller than me. I like being able to adjust the seat location forward / backward to lengthen or shorten the distance to the handle bars. The bike is very quiet. The adjustable feet are great as the basement floor is uneven where we ride. The water bottle holder is in an inconvenient location. We have a folding table next to ours where I put my water, weights and the blue tooth speaker. The bike was well packed. The box was very heavy. The delivery company couldn't deliver the box inside the house for insurance reasons. I was able to push the box into the house without help and it was awkward. There were tools packed in the box that were handy during assembly. The instructions were very clear. I put it together by myself as my husband was at work. Mine was missing the water bottle holder which Sunny customer service sent once notified. I did initially install the pedals that came with the bike so we could use it until the dual-sided spds I ordered arrived. Overall, I'm happy with the purchase. It's 1/4 the price of the Peloton so I wasn't expecting it to have all of the features the more costly bikes would have. It would be nice to have an output (watts) feature yet that comes with a price tag I wasn't willing to pay for. Would I buy it again? Yes. And I definitely recommend the peloton digital app as it's inexpensive (this is the $12.95 USD per month, not the $39.95/month version that their bike requires) with a lot of class & instructor choices.

Great bike but not the peleton price

Solid construction and easy to assemble; I have used it numerous times and the workout is for real, based on your preference of magnetic tension. I am 6'0'' 200 and have been really pushing in. It is everything I could ask for.

just ok

The bike overall seems ok, not exactly what I thought but I probably should have evaluated it closer. Wheel is a little clunky and package arrived damaged. Seat is relatively comfortable and the bike is at a nice angle but not sure I would recommend for a serious cyclist.
