I cannot say enough good things about this bike. My son saved his money to pay for it himself and it’s worth every penny. He is 11, it fits him perfectly. It rides so smooth and so sturdy. The brakes are amazing. It was very easy to put together. The best part is the sleek look!

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.

Seems to be good quality. Easy assembly. My son lives it and gets comments on the look of it all the time.

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.

My son is very happy with his new bmx bike. He has used it many times at the skatepark and it seems very safe and durable. My only complaint is that we paid for assembly and the company that did the assembly charged us extra. Amazon needs to fix this automatic assembly feature to be the correct price.

Die Montage war sehr einfach und unkompliziert.
Ich bin nun schon seit 4 Monaten fast täglich mit dem BMX unterwegs, mache aber keine Stunts damit (so krass bin ich nicht 😀 ) und es fährt sich einfach fantastisch. Meine Hoffnung, ein robustes Rad zu erhalten wurde auch bestätigt, denn das BMX hat einen Unfall mit einem Auto (Auto hat Rad von der Seite mit ca 20 km/h erfasst) ohne Schäden überstanden, bei mir war mehr kaputt. Der Reifen war leicht verkratzt (das Auto hat das Rad min 15m weit mitgeschliffen) und das Pedal war deutlich abgeschliffen, davon abgesehen nichts! Für mich beeindruckend.
Geiles Rad 😀

La taille est bonne, bmx de bonne facture, cependant des roulements scellé serait bien mieux 😉 et j’aurai pas dit non à un rotor.

Bike looks great However, It was missing a nut for the bolt that tightens the seat. I had to drive to a bike store and buy one for $5.00. Did not see an option on Amazon to ask for a nut which would be more helpful than a returning it all.
