My daughter has a spinal problem and can't withstand solid frame vibration. I'm looking for a 20" wheel girl's bike with soft dual suspension. Strngely, I find plenty 16", 24" or 26" wheel dual suspension girl's bikes but no 20"!! It seems Magna and Pacific Blue make 16" girls but no 20". Any ideas where to buy?? Toys-R-Us, Sears, Walmart, Kmart no luck. Thanks for any ideas.
Not sure about 20" girls dual suspension, but you may want to consider a suspension seatpost. It would probably serve the purpose your daughter needs and when she outgrows the bike, you can put the seatpost on her new bike. There are many different sizes (diameters) of seatposts, so most manufacturers make one or a couple of sizes and then offer shims to fit the rest of the size frames making. This would make swapping the post to another bike easier down the road.
