Query: Great Bike

Purchased MX350 last X-mas, my son(8) loved it, so did my daughter(9, who now rides MX350)). MX500 much faster, dual disk brakes. Takes a few minutes to get used to, but otherwise a bigger replica of MX350. Aside from standard ripped up box from Amazon, would definitely buy again. Came almost fully assembled. Make sure you get matching helmets, kids love them and must have, these bikes zip!!!!
