    Great bike for the money

    5 out of 5, reviewed on 04.27.2013


    My 9-yr-old son has had this bike for about 4 weeks now and has been on it almost every day even if only for 15 minutes and he really likes it! Its a cool looking bike and seems pretty sturdy. A lot of the other bikes we looked at that looked similar to this bike in terms of style were a lot more expensive. I did the online order with store pick-up and we drove over and picked it up the very next day. It was VERY convenient and didn't cost anything extra AND the bike was already put together.

    I like how you can switch the gears. It's also great for doing tricks on. It works well on my gravel driveway and through the bike trail in the woods by my house. I've had it for 5 months and I haven't had any problems. I really like this bike. It's a nice bike and the best one I've owned so far.

    This is a great entry level mountain bike.

    5 out of 5, reviewed on 10.26.2012


    This bike has many features only found on much higher price bikes, like a quality shifter and Shimano Derailleur. I bought it as a starter bike for my grandson. I guess we will see how it stands up, but the workmanship is good. I heartily recommend this bike, a good value for your dollar.

    Great bike, really heavy

    5 out of 5, reviewed on 04.08.2013


    I bought this bike for a 12 year old because I thought it looked cool, and he certainly agreed! That was was my primary concern, but it's actually a nice bike especially considering the price. It's got a full suspension and Shimano shifters that are easy and smooth to operate. Certain gear combinations result in a ticking sound from the chain but that happens on any bike. Just keep the chain on the center chainring and you'll have 6 very usable speeds with no noise. I like the quick-adjust seatpost as well. The only negative is the weight - this bike is very heavy but that is to be expected from a steel frame, and aluminum bikes are much more expensive. The rider probably won't notice the weight but I sure do when trying to load it into the truck. Still, I'm happy and would buy it again.

    Great even for a Women

    5 out of 5, reviewed on 01.12.2013


    I'm a 26 year old 5.5 135 pound women, I went to Walmart to seek out a bike that would last me. I narrowed the search down to this bike priced at $99 and the 24in pink women's Mongoose Mountain bike priced at $139. I rode them around and tested 4 other bikes for about 2 hours. I was not as worried about the price as I was about the workmanship and quality of these chines made bikes. Parts made of steal or aluminum so there will be a lack of rusting and nice shocks to absorb bumbs and such. I just got it but I am so happy with my choice, I will change/update this posting if the bike breaks down from manufactures defect and not from user abuse. My 1st bike was a Huffy that I got when I was in 4th grade and it lasted me through Junior year of High School till stolen. I got another bike after that, that fell apart 1 week after owning it. I am excited to try out this brand of bike "Next"! It came in black and a beautiful rust like orange, I wanted black so it was not going to be targeted by thief's and scrappers.

    Sturdy mountain bike, nice design

    5 out of 5, reviewed on 11.22.2012


    Sturdy mountain bike with a nice design. Springs help make impact softer for the rider. Purchased this as a gift. Free shipping. Great quality. Saw this assembled at the Walmart store and sat on the seat to make sure it was sturdy and comfortable. Looked at a lot of other bikes before deciding on this one. It's a little pricier than the others, but like I said, it's quality and sturdy.

    We have an 11 year old who is on the smaller size and this bike is the perfect size for him. He is able to change gears easily and the bike is not too heavy for him to maneuver.

    Good bike but can be taller than expected.

    4 out of 5, reviewed on 08.17.2013


    I reviewed other bikes and this looked better than the rest with the price. We needed a bike for a tall 9yr with gears so he can go up hills. This was easy to assemble, the cables are already attached so I didn't have to do any fine adjusting. The only big issue I had is that with the rear shock directly below the seat, I could not drop the seat all the way down because the rear shock is in the way unlike other bikes with a full hollow tube and no rear shock. (plus can't carry a water bottle) I guess he will just have to grow into it. The kickstand was a little poor and has a hard time holding up the bike. Another part I didn't like was that there was no quick disconnect for the front wheel maybe that is safer but at least the front wheel will not be easy to steal. He does beat the kids on the block with the 20" dirt bikes, so I think it was a good move. The post may seem to have some concerns but I am just trying to inform the readers and think for the price it was a good overall bet.

    What a Great Bargain

    5 out of 5, reviewed on 03.23.2013


    This has all the basics of a bicycle for enjoying around the local area.

    It's price is really spot on for an 18 speed rugged bicycle.

    It is not a sporting bicycle but neither is the cost.

    Nice starter mountain bicycle

    5 out of 5, reviewed on 03.11.2013


    We were pleasantly surprised to find this bicycle at Walmart. The paint schemes simple and understated and similar to the flat denim black on my Harley. For the price, it was a very reasonable deal. My son loves it--the gears are very manageable.

    A "Real" bike for kids.

    5 out of 5, reviewed on 07.20.2013


    This is what kids really want. The gear shifting is almost second nature. The all black finish and sleek design will have all the kids wanting to try it. It's powerful enough for adults as well.

    So far, so good

    4 out of 5, reviewed on 11.08.2012


    Only reason I haven't given it five stars is that we haven't had it long enough to know how it will last. My 11-year-old son was thrilled, as he saved the money himself, and this was the nicest bike he could afford. So far he's really enjoying it.

    Great bike for my 9-year-old!

    5 out of 5, reviewed on 04.25.2013


    The smile on the face of our son when he first saw it says it all.

    Although it seems a little heavy, it is going to be primarily used as a neighborhood bike, not a mountain, racing bike. Its sturdiness is probably a plus.

    We have only had it for a couple of weeks, but so far it has been great. Well-built, assembled perfectly and great looking. Seems like a very good value for the price!

    Each bike was rusty

    1 out of 5, reviewed on 12.14.2014


    We were very disappointed to discover after researching and deciding which bike to buy, that EVERY Next PX 4.0 bike was rusty! The rust was primarily on the screws going into the hand brakes and around the pedals. Please inspect closely any bike you consider purchasing of this brand.

    5 out of 5, reviewed on 08.16.2013


    My only downfall is I'm 5'1" and 24" is a little small and 26" is too big otherwise excellent bike. Definately recommend it to everyone. Light weight and durable.

    awesome bike for an awesome price

    5 out of 5, reviewed on 02.15.2015


    I am a 49 year old male bike rider who has had trouble in the past finding bikes that I could ride. I am only 5-4 and the 26' bikes are just to tall for me. I searched and searched for a new bike to use and I just could not find one. Went to Walmart a month ago and found the Next PX 4.0 Boys mountain bike ( I know what your thinking) A boys for a man. I know I thought the same thing until I brought it home and rode it for the first time. it shifted flawlessly, rode like a dream, and fast. I took the curves like I haven't in a long time... Walmart down the street from where I live takes very good care of their bikes and never stores them outside. My bike still had all the plastic on it, 'IE' seat handle bars and so on. I highly recommend this bike to anyone looking for a low priced Mountain Bike.

    18 speed or 6??
    Asked on 09.30.2012

    i bought this bike, and on the description it states that it is 18 speeds, however when I got the bike, on the handle by the gear shifter, it says 6 speeds. can you explain this to me? thanks!!! 24" Next PX 4.0 Boys' Mountain Bike, Black: Frame: steel frame Suspension: dual suspension Gearing ## of speeds#: 18 speeds Front derailleur: 3-speed front derailleur Rear derailleur: Shimano RD-TZ20 rear derailleur Shifter: grip index shifters/Shimano RS25 Brakes: equipped with V-brakes Wheels/tires: 24" wheels Hubs: steel hubs Rims: alloy rims Handlebars: steel handlebars Seat: MTB type seat with quick release Pedals: 9/16" pedals with reflectors Crank: 3-piece crank Weight limit: 230 lbs Assembly required Dimensions: 62.20"L x 22.83"W x 35.58"H

    • K260

      You should have 2 gear shifters, one on the left and one on the right. The 6 gears are the small gears on the back tire. The other gear shifter has 3 gears and they are the 3 large gears where the pedals are. There are 18 different combinations of both gears. 6 x 3 = 18 Gears.

    • Isbjorn

      It's an 18 speed.

    • Mom7boys

      I'm not sure about this bike in particular but usually there are 3 speeds on one side of the handle bar and 6 speeds on the other side. That makes for 18 different speed combinations. Hope that helps.

    Do I need to resemble it if I chose delivery to home?
    Asked on 10.09.2012

    • LegHornMachine

      Check with the store but I would assume that a home delivery would have the disassembled bike ship in a smaller box. You would have to put the bike together.

    Does this bike come in a 26"
    Asked on 11.19.2012

    • weld2962

      yes I bought black one for son, and white 26 for me

    • LegHornMachine

      No, this bike is a 24", that is the only option and it comes in 2 different colors. If your thinking about getting a larger bike, I recommend doing so. I am 5'4 and I realize on a longer ride that I need a larger bike.
