my son just started riding a bike about 2 months ago. so, i had to break out the bikes i bought my wife and myself about 8 years ago. ive got a full suspension mongoose and shes got a giant with rox shox. . i had left these bikes outside in the weather for about 7 years. (yikes).
so, when my son started riding, i had to fix them up.
both chains were toast. i found out that i could buy a chain from walmart for like $10, which i did for both bikes. had to get a new seat for one of the bikes too, which ran around $20. and i also found out that the tubes for the seats arent stock, so good luck if you need a new one. fortunately, the derailleurs work well enough.
in the past 2 months, i've biked assateague, a stretch of the c & o canal, and a nice path near my house around black hill park a couple of times.
fun stuff.
