I'm looking for a 20" (wheel) full-suspension mountain bike for my son with at least 21 speeds. He is 9 years old and currently has a 20" dual suspension bike (that we got at a garage sale), but it only has 6 speeds, and it's not enough for him when we hit the trails. His older and younger brothers and I all have 21-27 speed bikes, so it's getting hard for him to keep up when we hit any hills.
I was in the market for a similar bicycle for my 8-year-old son last year, and had a very hard time finding such a bike anywhere. Eventually I came across a new 20" full-suspension Triax 21-speed on Craigslist that I purchased and which he has ridden successfully ever since.
I've had a very difficult time trying to find any 20" dual suspension bike with multiple front sprockets for my 9-year-old in the past week, despite extensive Internet searches. I know the Triax is a pretty low-quality bike, but I can't even find any of those anywhere online (including eBay or Craigslist).
Can anyone provide a source for such a bike?
Also, is there a classified ads section of this forum? That would be the first place I'd look if I could find it. :-)
