I just bought a 12" off CL. Brought it home and it is bigger than the one she has now....looks like it's actually a 16" or bigger.
So......still looking
coaster bikes. greatest things ever. i bought them for my girls but they never used them. my son, different story. he wore one to the point that the axles broke. i had to poach wheel and other pieces of the other one to make a full bike. he even rode the course of the kittatinny kids race on it!
