## Description

For 45 years, Mongoose has been in the dirt, down the trails, and on the ramps. With the Legion Series, Mongoose offers a full line of freestyle BMX bikes for riders of all ages and ability levels. The Legion L20 was designed to be a fully park, street and dirt worthy BMX bike. The Legion L20 features a Hi-Ten steel frame (20.25” top tube), tapered headtube, and removable brake mounts. 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: Great quality bike and light weight - This Legion L20 is the third Mongoose BMX bike I've purchased over the last year, and I've been very happy with all three (Legion LSX, Title Pro, and L20). Assembly was very easy on all three bikes; just need to attach the front wheel, handle bars, and pedals. Took only about 15 mins. You just need to pay attention to the direction of the forks and remember the left pedal will be left-hand threaded. The forks and pedals have stickers denoting front/rear, left/right. Besides adjusting for height and putting air in the tires, there really wasn't any need for fine adjustments (chain tension, brakes, misc. nuts, etc.), as these things are being adjusted correctly from the factory (nice surprise). After reading the negative reviews on this bike and the others mentioned, it seems many of them are related to incorrect user assembly. If you put the forks on backwards or don't put air in the tire, you're going to have problems. The Legion L20 is reasonably light at roughly 25 lbs., easy to ride, and looks great. Note, however, that this is a freestyle bike, and probably not the best choice if you're just looking for a neighborhood cruiser. The crank bracket sits about 1" higher than on a race type BMX bike, making the apex pedal feel too high when in a sitting position. This may not bother some people. If it does, you could buy shorter cranks, but with the money you'd spend, it would be more logical to just go with a race style bike with the lower bracket (and larger front sprocket). The Title series with a lengthened seat post makes for a great lightweight cruiser. Not much to complain about on this bike. Excellent quality for the money. If you're looking for a reasonably priced freestyle bike with good quality, at $156, this is a great choice.
Review: Good bike for the money - 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.

## Questions & Answers

**Q: Are the bike pegs removable? My son wants to use it as a dirt jumper.**
A: The bike we received didn't have the pegs assembled.  As a matter of fact the pegs aren't that good. Slippery for shoes.

**Q: how much does the bike weigh in total**
A: Hi there! This model is roughly 32 lbs. when fully assembled. Thanks for reaching out!

**Q: My son is 7yr old and is 4'3" will the L20 fit him?**
A: For the most part, yes, it'll fit him. For those wanting to be technical no not all BMX bikes are a universal fit for all ages, but that's, in part at least, why there's an adjustable seat post to them, quite simply. Also, a quality BMX bike should be able to grow with a kid and accommodate his size as he grows. It might seem as simple as adjusting the seat post, but most of the youths tend to start off riding in a sitting position and grow to ride standing up more often than not, so adjusting the seat post height really becomes a non-issue soon enough. But another simple method is, have the kid straddle the bike. If the top tube is bumping his crotch, the bike is too big for him and vice versa.

**Q: Is the legion L20 a good fit for a teenager?**
A: For an L20 model I would suggest a rider 4' 8" – 5' 4" in height. That can be a wide range of ages that's generally 8 and up. Thank you, Nicole

### ⭐⭐⭐⭐⭐ Best bike around. My 10 Yr Old loves it.. I used to BMX and better than my bikes.
*by J***L on September 23, 2025*

This bike is Amazing. And even though I got it Used it came in Mint Condition still in the Box. Great Seller. My 10 Year old Daughter wanted a good Boys Bike and this one is outstanding. Much better than the Mongoose I had in 1984. I had to pull the handlebars back a little bit for her. Brakes are real good to compared to most that come on the bike. I think if you can get this for under $250. It's a steal.
