Review: I received the bike earlier than the date on the system. It was easy to assemble, and all the parts/tools worked very well. Definitely, a good option for starting a ride. The size guide on the product description also is a good thing to check and follow it.
Review: I bought this during Prime Day and was very happy with my purchase. I haven't biked in many years but now that my kids are getting into it, I figured that it was about time to reestablish my love of biking. It took a few trips to get used to it again but soon I was riding like I did back when I was young! As for the bike itself, this does come with some assembly required. It's not much, attaching the handlebars, attaching the front wheel, adjusting the brakes etc. The box includes some handy tools to assist in the assembly. It's not very heavy either so you should be able to maneuver it around while assembling. The brakes are very easy to adjust and I figured it out pretty quickly. The assembly book does use some technical terms and the pictures are sometimes difficult to follow but overall it wasn't too bad. I like that the bike comes with shocks which make for a much more comfortable ride. The only issue that I have so far is the lack of a kickstand which I didn't think I'd miss but I really do. I don't know why the company skimped on that aspect but you can always pick one up for less than 20 dollars. The bike feels well made and sturdy, gears are easy to shift and the handlebar is easy to adjust. I certainly received a great deal during prime day but even at full price, this bike is worth it.

### ⭐⭐⭐ Review
*by J***N on 25 May 2021*

Seat is a pain in the butt. If you're buying this bicycle as a replacement for another one you finally had to scrap, I hope you kept the old seat and if you didn't... well... if possible, go retrieve it ASAP and use it on this bike cause you're gonna regret it if you don't. The seats on these bicycles are so low quality and made with absolutely no comfort in mind. It makes an awesome implement of torture if you plan to break and split open someone's entire pelvic bones structure. I finally got to ride the bike after assembling it and I could not do it for more than 10 minutes. Extremely deceiving.
