  • Awesome for the price.
Color: Matte Black Size: 26 Inch
Very impressed for $200. Looks nice. It's reasonably light weight. Not quite used to the shifting yet, but the bike is pretty quick without much effort. Took 5 minutes to set up with the tools provided. Though, you're better off using a real screwdriver and wrenches if you have them. The only downside is the seat. It's rock hard, and without rear shocks, it's pretty uncomfortable. ... show more

  • Not a good purchase
Color: Gloss Red Size: 24 Inch
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

  • It is the right bike for the price
Color: Midnight Purple Size: 26 Inch
Quality is good, it is for weekend rides, nothing hardcore, or for competition level.. but is a good buy if you know what you needs are.

  • Instructions were tough....
Color: Charcoal Gloss Size: 24 Inch
I got this for my 12 year old. It had a few scratches and arrived partially assembled. The assembly ended up being easy enough but the instructions were not clear at all and there were shipment parts attached to the bike that were really hard to remove. I ended up calling Huffy to help. Nice quality bike, though. ... show more

  • Solid Structure, Sleek, Well Built>AFFORDABLE........
Color: Gloss Red Size: 24 Inch
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

  • Brakes are too short
Color: Silver Gloss Size: 26 Inch
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

  • Brake levers rotated upward
Color: Matte Black Size: 26 Inch
The brake levers are upside down and above the handle bars. I can't loosen and rotate them to the correct angle because the brake wires block the allan wrench hole for the brake levers on both sides Update: I found the solution. I had to loosen the screw just below the center of the handle bars and rotate the handle bars and brake levers as one. ... show more
