Color: Grey Size: 20-Inch Wheels L60

Let me be up front, I paid $179 for this bike. It is the gray L60. I just looked again and the bike is now listed for almost $350. I’m not sure I would pay that for this bike. Not because it’s not worth that, but because I would probably buy a higher end brand for the same price. But, that’s just me. I bought this for my son on his 9th birthday. He is very tall for his age at a little over 5 feet. According to the specs, he would be on the bottom end of the height range for this bike and it fits him perfectly. I am 6’ 2”, 250 pounds and I wouldn’t hesitate to buy this bike for myself based on the dimensions. The handlebars are a really nice height for me to ride. I could not find out what the exact material the frame is, but it is very light. I was hoping to get him a Chromoly frame, and I would say that this would fit in that weight range. Everything is very stout and tight. I would not personally hesitate to take this bike to the park and jump it… Which I did. The crank did not flex at all, and I really love how fat the tires are. All around, I am impressed with the bike. The paint job had a nice detail in it near the welds to mimic a heat blemish, which is a throwback to the old days, when chrome bikes were welded and the heat would blemish the chrome and turn it a rainbow color. The only Cons that I really found with the bike was under the fork where the neck stem passes through the fork and is welded in place, there was a really bad cut and weld. There are also a hint of rust on a few parts of the bike. I’m assuming from being shipped overseas from China. The metal Mongoose decal for the front of the head stem was a stick on thing. It may be that kids these days want a clean look and they did that as an option. Other than those things, I can’t find anything else mechanically or geometrically wrong with the bike. To be clear, this is not a Walmart licensed product. This is a mongoose bike produced by mongoose or the company that owns mongoose. p.s. it wouldn’t be a bad idea to make sure that the neck, crank and wheel hubs are all at the correct tightness. They feel a little tight out of the box. This is super easy to do yourself, but if you’re unsure, just take it to a bike shop. ... show more

    • L60 Grey! Best Value BMX while it lasts!
Color: Grey Size: 20-Inch Wheels L60
Was looking to get back into BMX. I mean I'm buying a BMX for my 5yo son (wink). Just wanted something like I had in the 90s. Everything was $200 and above. Walmart has a Mongoose Rebel X1 for $182 that I almost bought. Then suddenly, as if reading some kind of chip implanted in my brain, or device, Amazon shines light on the Mongoose Legion Intermediate L60 in Grey for $153. The listing photo does not match and shows a L20 grey but the listing "Part Number" comes back as the proper L60 in grey and is what you get. I wait and the price goes to $155 but with a 20% off coupon. No brainer from there. The Legion 60 is an upgrade from the Rebel X1 which I match most to the Legion 20 from what I can verify and see in photos. The L60 has a sealed rear hub and sealed head design that makes it superior to the L20 and the L40 which had a sealed rear hub. The L60 does not come with pegs but the front axle will accept 3/8 pegs or the Mongoose Freestyle Steel Pegs. The rear axle is 14mm so you need larger diameter pegs for the rear. The rear-axle has plenty of thread left for pegs. The seat tilt is fixed. The head part of the frame already has slots ready for a gyro brake system but the L60 does not have the system installed. The frame is Hi-Ten steel which I don't mind and is what I had back then anyway and you cant really find chromoly frame builds for less that $300. $130.37 out the door on this bike for what it has is a super duper deal. It is made in China but for an OEM bike, I could never build something like this for that price. A frame and maybe wheels without tires is most I'd get under $150. Congrats to all who got the L60 in grey at a great price. Thanks Amazon for the super ai deals and Mongoose for still making and baking. ... show more

    • Good Bike, Bad Assembly Manual
Color: Red Size: 20-Inch Wheels L20
< Overall > So first off, this is a decent bike. Having twin boys this has all the cool features that they didn't even know they looking for (that's because these were features I was looking for at their age); free wheel, spinny handlebars, foot pegs, and a cool color scheme. I've read some reviews of this bike on other, bike-oriented sites that pick apart certain mechanical aspects of this bike and I must say people sure seem to expect a lot for this price point. From my perspective--and having grown up with a Huffy--this is about the nicest bike I could imagine having as a kid. < Assembly > Having twin boys meant that I got to experience assembly twice. Which is the reason I deducted a star from the bike, the assembly manual is generic and meant to cover several versions of these bikes. As such it does every version of the bike a disservice by not actually explaining things very well or at all in the case of the brake cable installation for the L20. There isn't a lot to the assembly. The main frame and all the components are already installed. You just have to put on the front wheel, mount the handlebars to the stem, install the seat, pedals, foot pegs (if you even want them), and finally attach the brake cable to the brake lever. Having a metric socket set and Allen key set are essential. < ASSEMBLY NOTE: Attaching the Brake Cable > I've seen more than a few reviews here decrying the assembly of the brake cable with folks going so far as to return the bike, buy additional parts, or dump it off at the bike shop. Let me say I understand your struggle. However, I did figure out how to install the cable without needing to go that route and it was actually pretty easy. The cable, as it turns out, is the right length, but I found it necessary to disassemble the brake lever and remove it in order to make it work. I takes the 4mm allen key to remove the screw. The lever components include two plastic bushings on either side of the lever and a spring. Pay careful attention to how these parts come out, because reassembly is the same. Once the lever is off and the brake cable is fed through the lever mount, you can line up the cable and the barrel in the hole on the lever and rotate it into place. Now you'll actually have enough leverage to easily re-seat the lever arm although it will require a modicum of coordination to make sure all the parts stay on the arm until you can get them back into the handle-bar mount. I don't know if I explained that well, I'm not even sure if that was the easiest way to do this, but it worked reliably for me. < FINAL NOTE: Test! > Once everything is assembled, test the bike. I cannot stress this enough. Don't assume that because it's all been assembled it's ready to go. The manual itself makes a big point of this as well. ... show more
