hmm.. im gonna consider the day i turned 18 as my "adult years" so lets see...
i learned how to ride a bike late (4th grade) and i only remember them based on what grade i was in.
4th-5th
cheapo magna mountain bike that was way to big for me that i cruised the streets with my cousins. addiction the cycling starts.
6th-7th
super heavy full squish duel crown pacific bike. I remember seeing a old canondale mag with a full-sus bike and i knew i wanted something like it. it got stolen out of my families shed with my old magna bikes.
(not mine, but just like this!)
7th-8th
GT performer bmx bike. i thought this thing was so freaking rad. it had this curved top tube and the front fork had a separate add on part just for pegs. I worked with my dad for a few weeks to save up and this was my first multi hundred dollar purchase in my life.
(not my actual bike but this same frame and color)
9-12 High school
i primarily rode around with friends on BMX bikes. i had a old matt hoffman bike that i got for free then i rode around a built up kink transition that i hand polished
then a little after that i started to experience really bad wrist pain. prob from jumping to many stair sets and not landing much of them. i wanted to stay in the freestyle scene so i got my first 26inch DJ bike. black market riot
this was actually the first bike that i took to sixmile. sold this bike a bought a old ironhorse and have owned a few other mountain bikes since then till my current ride. been on dirt since.
