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.

Great sturdy, smooth riding bike! Great buy!
I am an 84 year old male, 6’2”, 203 lbs, who has exercised regularly. I have had two knee replacements, toe surgery, have peripheral neuropathy, causing balance & gait issues. I normally ride an upright stationary bike (at gym), swim, acquacise, & walk using trekking poles. Since Covid19 has closed our gyms, I chose to buy this bike, & am very pleased with it. It is heavy, sturdy & super quiet.Assembly: Working alone it took 1.5 hr just to get it out of the box. But once out, assembly was fairly simple. The packing was sound & protected the bike & parts well. Instructions were sufficient and other than a few minor glitches, assembly went smoothly. You definitely need one other person to assist in getting the bike frame in an upright position for further assembly. Once out of the box, assembly took ~ 3 hrs.After assembly mobility was good, requiring one other person to assist in guiding it around a few corners & doorways into a bedroom/office. Placed on a thick yoga mat, it works well. Chose that rather than a exercise mat, which might leave residue on the floor.I’m not a spin bike guy, but that could change. This is a great, sturdy, well built bike. It is super quiet, easy to ride, yet could use some design improvements. The seat was rather uncomfortable, so I replaced it with a “Ximfer Oversized bike seat (AMZ), which works better, so far. The seat vertical adjustment could use a greater range as well as fore/aft placement. The handlebar rack fore/aft placement needs greater range. The inner two bars work well to support use of an iPad, or phone. The outer bars of the rack could’ve been designed better, too flat & forward. The belt drive is great , smooth & quiet. The toe cages are well designed and work well. After three weeks, I am very pleased with this bike. A sound purchase, even or especially at my age & level of bike expertise. Trust this bike will serve me well, as l begin to learn more about it.

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
