Un mes con ella y es una excelente bicicleta. Se siente muy buen material y se nota a simple vista, bastante ligera. Solo al principio hay que batallar con el armado porque viene semidesarmada pero nada que no se pueda hacer con un par de llaves y paciencia. Ya dependerá de ti si quieres ir metiéndole otro tipo de piezas o modificaciones después, pero así de serie es una pasada. Ya me la han chuleado varias veces. Solo señalar que no es para recorridos largos, puedes hacerlo pero si es algo pesado al principio, más para las rodillas y la cuestión del asiento, es algo duro. Pero no es una bicicleta para viajes, es para acrobacia la BMX. Medidas yo mido 1:70. Todo sin problema.

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

Very easy set up!. Must skip through some of the install instructions as the bike does not have front brakes for install. The bike has a back break only and does not come with front and back foot pegs, we used ours from my son's old bike. I am not sure if it mentions that in the description because to be honest I didn't read the whole description at purchase haha The bike arrived quickly without damage and is absolutely awesome and sturdy. My one reccomendation is the bike frame space at the back does not allow a hookup for kick stand... minor setback.

The box has terribly damage and some dents scratches in handle bar, but still Look Good

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.
