    • Indestructible
Style: 26" Denim Blue
This bike is great. I bought this thinking it would last the summer, and here I am still hauling my now 6 year old in a trailer behind it 3 years later. Sure, some of the gears are slipping a bit now, brakes don't work. But for the price you get a very solid platform. I plan to put an electric motor on this thing and drive it to my grandkids graduation one day! ... show more

    • Perfect trail cruiser with a few upgrades
Style: 26" Matte Black
The media could not be loaded. I’m a bigger guy (6’ 240lbs) and this bike has been great so far. I was worried it would fall apart after a few runs but it has held up great for well over 2 dozen rides. It took a bit to get the gears shifting properly but i have them dialed in now with no hesitation or skipping EVER which surprised me. 3 things I would recommend: First I bought a nice wide, soft seat which makes a huge difference as the stock one is like sitting on a skinny rock. Second I bought wider, longer hand grips. My hands were hanging off sides of the ones that came stock. Lastly, and what helped me enjoy this bike the most was upgraded metal spiked pedals. The stock ones are plastic and my feet were sliding off them constantly especially on wet days. Probably spent a total of 75 bucks on all the upgrades and it was well worth it. I’m not jumping off any cliffs or anything just cruising through the bumpy woods and this bike has been perfect for that. ... show more

    • Not a good purchase
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

    • Nice bike for the price
Style: 26" Denim Blue
It came mostly assembled except for the handlebars, seat, peddles, and front tire. I'm 6' and it didn't feel like I was able to get good extension with my legs without raising the seat a lot. Adding a layback seat post helped provide a couple more inches of leg room. The noodle on the front brake broke when making initial adjustments and needed to be replaced. Overall it seems like a good bike in this price range. I'll provide any updates if needed once I get a few miles on it, after it cools down and the temps are no longer getting into the 100's. ... show more

    • Mediocre quality
Style: 20" Metallic Cyan
The frame of the bike is good and my son is enjoying it. The bike is not the highest quality though, and I expect it will not last more than a year with as often as my son uses it. The front wheel was slightly bent out of the box, which made adjusting the front brakes a real joy. Most annoying is that the handlebar/steering arm will not stay in place, no matter what. Every time my son drops the bike with even mild firmness, the handlebar gets misaligned. The manual says to be careful about overtightening, and I heeded that advice initially. Unfortunately, I have found that even cranked down at max strength, the handlebars still won't reliably stay in alignment. I have concluded it's the result of a poor fit and cheap fasteners. Same issue with the seat. Oh and the clearances on the kickstand are so tight thst my son has trouble raising and lowering it. I plan to fix that with a Dremel. Next time I'll spend the extra money on something with a little better build quality. ... show more

    • Love this bike so much
Style: 26" Matte Black
comfort is key when it comes to riding. The seat on this Huffy bike adjustable and well padded. I took it for a spin around the neighborhood, and I must say, it provided a comfortable ride. The handlebar grips are also soft and easy to hold, making longer rides more enjoyable.”

    • 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
