I got it retailed for quite of a good deal below $400. And I’ve been using this BMX for a solid 3 months here and there and it doesn’t really disappoint, as long as you greased the metal parts, it’s smooth as butter The instructions on the brakes could and bearings of the handle could be more accurate and clearer though And the bikes itself seems to be a little heavier than a typical BMX. That’s the only issue I ahve with it, the weight. But nonetheless it’s overall a decent bike

This bike delivered quickly and well packaged. It requires a bit of assmbly but instructions were clear and assembly time was relatively short. The bike is well made, rugged and has some quality components on it for this price point. We waited for a number of trips to the indoor bike park to be completed and I have to say, it has been out through it's paces, to say nothing about it having suffered a number of gnarly dumps and it is still doing it's thing and not looking bad, save a few scars. If you have someone in the family that is starting out or looking to step up from a "cheap" BMX styled bike, this model is an excellent option. Definitely recommended.

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.

This is a super nice bike that my son loves and is the envy of the neighborhood kids. The assembly went very well until trying to get the brake line assembled. After hours of trying we gave up and took it to a bike shop. They had to fix the factory setup as it was incorrect when we received it. Other than that, this bike is great. My son is very happy with it.
