The L20 Hi-Ten steel 8” rise handlebar and 48mm stem are designed for precision riding, while the wide aluminum single wall 36H rims and 2.3” BMX tires offer grip and durability. The 25x9T gearing with one-piece tubular chromoly 170mm hollow spindle cranks and American loose ball bottom bracket offer a clean, reliable drivetrains. An alloy U-brake with alloy brake levers provide speed control, while the Hi-Ten Steel BMX fork with 1-1/8" threadless steerer and taper leg helps maximize performance. This bike ships ready to be assembled and comes with a 5-year limited warranty on the frame and a 1-year limited warranty on parts.

Review: Sturdy and well made - Extremely well-made bike. Sturdy and heavy. Mongoose is always a reliable brand. Love the teal color. Highly recommended!
Review: Yes! Mongoose is back to the good stuff!!! - Just get one. This is Mongoose like in the 80's and early 90's. Not the junk crap that Walmart and other department stores still sell. Avoid those like the plague! But then, that's apparent to any real BMX rider. Those are all flash for what little you pay and no real quality. If you already have one of those, strip it down to the bare frame and only the frame and build everything else up from scratch. That's those bikes only hope. This on the other hand is fine the way it comes. Ok, may have to make a few tweaks and whatnot along the way, but that's to be expected of even the best BMX bikes. It's part of riding and making it your own. I do wish they'd have given it at least a somewhat taller seat post, and I'm also not crazy about how the seat is permanently attached to the seat post as well. Normal seat and seat post setup is, if the seat wears out or isn't to your liking, you can just stick a new seat on the seat post. Here, you have to replace both. Was expecting something like a pivoting seat post or perhaps the old bolt down kind. On the other hand, the seat that's here, by BMX standards, is plenty acceptable until I upgrade. I got the L60 and I'm not sure it mentions it in the details, but it appears as though it's sporting a rear wheel that's sealed while the front wheel is not sealed. But the L60 is totally the midrange offering of the whole Legion lineup. So it's expected that a few things are somewhat average, besides, the rear wheel is where you want and need a better quality one at, uh, if you're going to cut corners that is. Also, contrary to what I'm seeing in other reviews here, the brakes do work surprisingly well. More than adequate. The bike arrived perfectly and overall inspection found one very minor blemish. Top tube on left side has like a weird smudge in the paint job that then glossed over for it's final painting. I tried Goo Gone thinking it might have just been grease, it's kind of a blackish color against green giving that effect sorta, but after a good rubbing it remains unchanged, so I can tell it's permanently on there. Both very minor and totally cosmetic, a classic error no doubt the result of being mass produced. Everything else is brilliant here plus I caught a sweet sale on mine and got it for only $146.87 + tax. Arrived quickly, packaged well, everything is in perfect condition, so yeah, I'll excuse one little minor smudge. Thank you Mongoose!!!!

### ⭐⭐⭐⭐⭐ Good bike for the money
*by H***T on December 21, 2020*

All you need are some tools, a brain, some patience and reasonable expectations for this to be put together and on the road. If you have half a brain and basic tools, you’re going to be able to put this together without even looking at the instructions. This will come in a box, front tire packaged off. It comes with no tools, everything zip tied so it could remain intact on the long trip from CHIIIINA to the US. Packaging is solid. There are several thick zip ties to cut to break everything loose. You’re going to need: Metric hex tools A 15 and 18 mm socket for axels 15mm wrench or socket to tighten handlebar alignment Scissors or utility knife for zip ties Phillips screwdriver (for the reflectors only) You’ll need an extension bar to remove the nuts from the axels to install the pegs on front and back. Will take you about 60 seconds to do this. Front handlebars install with hex keys. Honestly not sure how anybody could have problems with this. It’s four bolts. Secure them, and you’re good. But man, some reviewers couldn’t figure this out. Install the seat with another hex socket. Put on the reflectors, hook up the brake, fill the tires with air, and you’re riding. Btw, the factory purposefully ships tires with less air than you’ll need for your benefit. Any tire sitting for an extended period will last longer if not fully inflated. Hooking up the brake is a bit of a pain in the A, as you won’t have enough slack in the front to properly attach the cable unless you briefly disconnect the rear brakes. Once you pull the cable through in the front to attach, reattach the rear. Took me a minute to figure this out. The front break setup is such that you can spin the handlebars around to 1) look cool, and 2) not have the brake line get wound around the front of the bike. The bike is good, solid and worth the money. Assembly, with any mechanical skill (even entry level mechanical skill) will take 20 minutes. Also, warning: you’re buying a $200 bike. It will last like a $200 bike. Many people on here complain about the quality. This isn’t a $1000 bike. Don’t pretend it is. Take care of it, don’t beat it to death and you’ll be good.
