Currently looking at models from GT, Diamondback and MongooseAlso, should I get aluminum/composite over high-tensil steel? Thanks!
Please reconsider thisThe size needs of a 5 year old will change very quickly and you will end up buying bikes over and over againBut since you askedFirst, BMX bikes are also known as bicycle motocross and are made for racing in the dirtthey should never have pegs installedYou are looking for a flatlands or freestyle bikeNext, keep in mind that pegs are to facilitate tricks and not to carry his buddies aroundFew 5 year olds have the brains to think about the potential injuriesIf you DO put pegs on the bike put them on one side only, not the front or rearThird, all the brands you mentioned have entry level bikes in your price rangeMost stunt and freestyle bikes are steel- either Chrome Moly or Hi Tensile while you will find BMX in aluminum and carbon fiber composite(though probably not in your price range)Hi tensile steel is the low end stuff, aluminum is next, then Chrome Moly, then comes carbon fiberBy the way, contrary to another answer, both hiten and Chrome Moly are the same weight, but since Chrome Moly is stronger it can have thinner tube wallsLess material, less weightFor $250 you can make your choice- ignore brand names but DO get it from a bike shop (not Walmart ot Target, etc)They will fit him properly and offer service as wellThe VAST majority of bikes are now made in a handful of factories in China or Taiwaneven if they say Designed in the US or Built in the US (of foreign and domestic parts)Finally, make sure he has protective gear and uses itespecially a helmetOne trip to a hospital will be far more expensive than any helmet, and a lot more traumatic for both of you.
