Review: For the price, it’s real good - 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
Review: Buen producto - Todo muy bien, solo que el brazo donde van los pedales no tenían la rosca, tuve que mandar hacerla en un taller.
