    • Great Bike at a good price!
Style: 26" Matte Black
Easy to put together and get on the road. Only adjusting the brakes took me some time. Like the gear selection and it works smoothly. Will probably change the seat out later but that's a matter of preference.Overall a great bike!

    • Not a good purchase
Style: 24" Red
Bought this for my 10 yo for Christmas. Bike took some time to assemble but came together pretty easily. Issues: The wheels are not straight and contact the brake pads sporadically while riding, making a scrubbing sound. I made significant adjustments to the brake pad spacing but could not easily dial it in to the spacing referenced in the manual - needed wider spacing to avoid contacting the tire. The derailleurs were not indexed properly. I followed the instructions step by step to set the low and high limits, then adjusted the thumbscrews to adjust the indexing. I spent 4 hours (not exaggerating) adjusting and could not get the shifting to work properly - it skipped gears, and the bike would often shift gears on its own while pedaling. Front derailleur was trash, could never get it to shift into the smallest gear. The shifters were “tight” especially for the front gearing, my son couldn’t even shift it to the smallest gear because it was so tight. Ultimately I decided to return it, too much wasted time trying to make it functional. Don’t waste your time on this bike, it’s trash just like many of the other reviewers said. I wish I’d listened to them, but I was attracted to the positive reviews and the price seemed reasonable. At the very least, don’t trash the box after buying it, because you can’t return it without the box. I had to buy a $20 bike box just to return it after trashing the original box (which was damaged on the bottom). Fortunately Amazon covered the cost of the bike box and made this return process pretty easy. ... show more

    • Works as good as any cheap bike should
Style: 26" Matte Black
I bought an open box example of this bike and it works as good as any cheap bike should. Some assembly is required, but bikes are painfully easy to work on. The grip shifters that come with this bike aren't great, but you can upgrade them to a better shifter set for around $20-$40. This upgrade and a better seat will make your $200 bike feel like a $800 bike. ... show more

    • Great value if it’s on sale
Style: 26" Cloudy Gray
For someone that does casual biking, this thing is awesome. I got it on sale and it’s amazing on gravel and pavement, so far that’s all I’ve tried it on but it handles likes champ. I used to be a bike builder so putting it together was extremely straight-forward, although I put together two of these and both had the pieces for the seat clamp sprawled all over the bottom of the box; very lucky they stayed in the box even with being shipped all the way over to Hawaii. The seat isn’t that comfortable but that’s what to expect from a cheap bike, and you can always swap it out for whatever seat fits what you’ll use it for. Gearing needed to be adjusted just slightly, and works great even on bumpy terrain. I’m about 220 pounds so I tightened up the tail spring a good amount and it glides over bumps, fantastic deal. ... show more

It went together pretty easy without reading instructions. Adjusting the brakes was kinda hard

    • Brakes are too short
Style: 26" Charcoal
EDIT 10/22 The seat broke. It keeps tilting back when I sit on it. I literally cannot tighten the nuts anymore. The seat is going to have to be replaced. Really pisses me off. This is a pretty good bike. I got this bike after spending years riding my mon's old Giant(which costs about $500 in today's money), and while it doesn't quite measure up to that one, it still feels pretty comfortable. It rides smoothly, and the gears are noticeably different from each other. I switch gears a lot when going against the wind or going up or down hill, so it was important the gears worked well. I brought it to a bike shop to put together instead of doing it myself to avoid any problems from poor assembly. Early on I had an issue with the right brake sticking, and I took it to the bike shop that put it together but it unstuck at that point and the bike shop couldn't see any problem. The brake hasn't stuck since, so it could just be that the bike needed breaking in. A bigger issue with the brakes is that they're simply too short. I can't comfortably rest my fingers on them when I'm riding (which you should always do to be safe). I can only really get one finger on them. The brakes are only half the size of the handle, and the inner part of the handle is taken up by the gear mechanism, so I can't put my hands any closer to the brakes without accidently changing the gears. Seeing as this is a women's bike, and women have smaller hands then men, this is strange. It's a minor issue though. Overall I'm really happy with this bike, especially considering I didn't have much of a choice since it seems there's a bike shortage because of the pandemic. ... show more

WOW, It took me a FULL Week to decide which Huffy sized Bike I would buy. I originally was going to purchase the 20 inch til I saw for a "girl" I assumed this meant a child. YES I am short 5 feet. So then I went looking for a 22 inch.I could not find one.Now my 2 brothers growing up had the sting ray cool looking Huffy bikes. So I strictly surfed HUFFY Mountain Bikes still NO 22 inch, what did I know, I have not ridden a bike in 37,38 years, lol, lol. The info on inches and heights was there right in front of me..This AWESOMELY made, relatively easy to put together, took about 1 1/2 hours>PERFECT!. I watched the video which clearly walks you through the entire process. OH My the Crisp Red color,The sleek cool looking awesomely light weight solid structured fit me to the TEEEEE...This Bike is NOW in my TOP 3 items I have ever purchased on Amazon..that I cherish the most..The cost is nothing compared to how I/We/You are going to feel proudly riding on this Bike. I rate this Huffy Mountain 21 Speed, 24 inch Huffy Bike a Perfect "20"....Now instead of driving to Lake Champlain I will ride there.... ... show more
