I had a JD 10 speed when I was 11 or so it was black with suntour componants and 27in gumwall tires. I put many many miles on it, the bike was heavy but solid I beat the tar out of it with verry little trouble.My sister also had a JD 5 speed girls bike it was white and I think you could get a 10 speed kit for it.
Noyhing run like a deer.
