Great value, great bike, and solid option for DIY Peloton
***Update (over a year later, 3/8/21)***Bike is still going strong. I had a small maintenance issue with the left pedal crank arm and pedal threads, but luckily the bike was still under warranty and they sent me new pieces. Make sure your pedals are tight before/after each ride to ensure you don’t damage those threads! I’m so glad I went the Sunny/build-your-own-peloton route, because while I love riding the bike, I found myself enduring some boredom here and there. So it’s nice not being tied to the Peleton ecosystem and $39/month bike subscription. At least at $13/month for the app I don’t feel too bad if I choose another cardio method a few days per week. I did modify the handles by adding some padding…not because the handles hurt, but because apparently I have short arms and I was finding myself out of position reaching for the handles. I saw others use really thick pool noodles wrapped around the bars. I just used old t-shirts and it worked just fine. The wahoo sensors continue to give all the info I need to be effective in my rides while following Peloton instructors on the app.I still absolutely recommend this bike and the setup I described below. I’m sure I would have liked/loved the Peloton, but I’m glad I ended up not spending all that money.****Original review**** (2/29/20)Really happy with this bike so far. About 50 rides so far (January 2nd through February 29th) by my wife and I. I’m 5’10”, she’s 5’4″, and we both fit on the bike. I will say the position of the handlebars is a little further forward than I would like (when fully adjusted back). I would say my arms are average length for my height, and with the seat in the right position for placing my knees in the right place, I have to reach out a decent amount to get to the handle bars. I use the Peloton app and I notice the instructor’s arm position is way more angled at the elbow than mine and I can feel the soreness in my shoulders and triceps after a week’s worth of rides.But that is my only complaint/issue. The rest of the bike is sturdy, well-built and an insane value! The magnetic resistance is fantastic. The bike is quiet and rides really smooth. Adjustments are easy to make for seat and handlebars. I replaced the pedals with clip-in pedals, so can’t speak to the included pedals.Currently using the Wahoo cadence and speed senors as well as the Wahoo heart monitor strap to track my stats. Definitely a cost-effective and solution-effective option vs the full Peloton bike. Glad I have the extra $28/month from the subscription in my pocket plus the $1700 difference between the bikes/setups.

Exceeded expectations.
First off, I had to return the first bike because the carton was seriously damaged and I didn’t want to take a chance on unpacking it and then trying to repackage it to return it. The return went fairly smoothly, Sunny Fitness was very responsive and helpful. The second one came 5 days later, also damaged carton, but not bad enough to make me return it. I got credit from Amazon a few days later when the first bike got back to Louisville.This SF B-1805 bike is everything as advertised and more, in my opinion. I have been riding a Trek Cronus road bike, and was concerned that maybe I would have to make concessions in fit, riding position, seat comfort, etc. with a stationary bike, so I spent a lot of time comparing bikes to get one that could be fit to me. My due diligence paid off, as I have been able to adjust the seat horizontal position, height, rotation, and angle exactly as I wanted to, as well as the handlebar height and distance from the seat, which I now have set up the same as on my road bike. As expected, I added bar tape (Cinelli gel-cork) for a softer bar feel. I am happy with the resistance adjustment, and after a little experimentation I can set it to imitate hill climbs, etc. It is totally silent and smooth, pretty near road feel, (except obviously no free-wheeling). Structurally, I think it is a little over the top, everything is extra sturdy and very well put together. It is well engineered — I am a retired mechanical engineer — with beautiful welds, sturdy adjustment handles that allow for clearance of seat post and bar post, stainless steel hardware, attention to detail, etc. Made in China is no problem here. I had to get a younger, stronger friend to carry the main frame down to my exercise room in the basement, as it weighs 99-lbs, which gives you an idea of how sturdy this thing is. Total weight I think was 128-lbs assembled. My daughter and I put it together with no problems in 45 minutes, taking our time. We had to work to get one of the base frame bolts through, and the adjustment handles were a little of a puzzle, but only because I hadn’t seen the type before. This bike is well worth the $600 I paid for it. Highly recommended.

Sturdy, well designed, and smooth
I LOVE my Sunny bike! I generally speaking despise exercise bikes since many of them are poorly designed, squeak, wobble, or otherwise feel a bit on the rickety side. Not this bike. Solid as can be. Quiet and smooth. It was extremely easy to assemble – though beware that it is heavy – and is extremely fun to ride. Well, as fun as anything you use to exercise can be, anyway. A few people told me to go for the more expensive brands, but I chose wisely. This is a really nice machine for the price and I suspect it will last longer than my inclination to exercise on it, though I have happily used it most every day for three months now. I’m not a super motivated biker, but I have stepped up the resistance on the bike and it is smooth and really makes you work. The seat was pretty comfortable as stationary bike seats go, but I did replace it with one a bit wider since I’m a good sized person. I remain impressed with the bike and will say that you can’t really go wrong with this Sunny.

لاتخسر وتضيع فلوسك مثل تجاربي السيئة سابقاً في بعض المنتجات الرياضية التي لاتدوم 6 اشهر او حتى سنة ياتصدي او تنكسر احد الاجزاء …الخاستثمرها في دراجة تمارين ذو جودة عالية ومتينة وتتحمل مثل هذا واحد من البراندات المعروفة والاصلية sunnyشوف مجموعة مراجعات في اليوتيوب عنها وعن اي منتج اخر ناوي تشتريه وبعد كذا قيمها قبل اتخاذ قرار الشراء !ملاحظة :اغلب الدراجات الثابتة الكرسي قاسي وغير مريح يفضل شراء بطانة بحشوة مريحة وتلبسها بالكرسيالدراجة لها معي اكثر من 3 اشهر واداءها ممتاز والحقيقة حبيت المنتج وراح اكتب تحديث مراجعة بعد فترة ان شاء اللهبالتوفيق للجميع

La cyclette è abbastanza comoda ma i materiali sono scadenti rispetto al prezzo.

OK these are my first opinions and I will update this if I have problems after a few weeks …I received the bike today and it needed 2 people to deliver the box to the room of my choice. The first thing to say is it is damned heavy and no way could one man deliver it.To make this short I’ll just say it is packaged superbly and it is so quick and assemble. Allow 30 mins and this includes making a coffee half way through. The bike is real quality and when built is so sturdy. I did 20 mins just to try out and its so smooth and whisper quiet. My only real complaint are the pedals. They have straps on one side but the other is missing SPD cleat fastenings and I’ve searched all over and can’t get them so basically you need to buy new pedals if you want SPD clip ins on the opposite side to the straps. No way near a deal breaker but the addition of them would be the cherry on the cake.Anyhow you may have guessed I’m impressed with the quality and the ride so hopefully when I get more miles In the bike will continue to deliver. I will add as a final point there is no screen or any readout so if you want cadence and heat rate you will need to buy something like a Wahoo cadence sensor and I would recommend the Wahoo tickr arm worn heart rate rate monitor paired with a mobile phone and the Wahoo fit app.Happy ridingMike
