So far so good
Bought the bike for my 11 year old for Christmas and he loves it. He says it's lighter then others he has had and it's easier to do tricks with it. So far it has held up to him riding it everywhere and putting it through/treating it the way kids treat stuff.

Happy L80 owner.
I love my L80...I'm 49 can't bunnyhop like I used to but even in this cold winter Ohio weather I ride my L80 daily and love this bike,she even sleeps in my room with me, thanks mongoose for keeping the BMX tradition going...just don't settle for mass retail and stick with quality products...also the employee's in China that put the L80 together did a fantastic job,the welds are beautiful.
