Review: For beginners is good - This is not professional bike for sure but for beginners its ok
Review: 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.

*by F***E on 17 May 2024*

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
