Sizing notes

Bike measurements are stated in millimeters.

Rated 3 out of 5 by from Overall good value if you are willing to tinker Overall good value. Frame is good, components are good. Gearing is nice and all. I do have one major problem with it though. Safety! Brake is marginal at best. It has STI shifter and V brake! As I found out later, my kid almost couldn't stop in time which could have been disastrous... Diamondback really should be putting proper brake on this bike for the matching lever. For those of you who is more mechanically inclined you can put probem solvers travel agent to increase pull from brake which is what I did. (basically makes brake move in twice faster)

is this a good bike for a 9 year old boy that is skinny and a bit tall? He currently has a Novaro Duster 20 inch and he seems to be too big for it now.

Asked by: Christian the Martian
Children require 2 to 4 inches of clearance from the top tube of the bike. The top tube is the section of the bike that a child would straddle with both feet on the ground. The standover height of kids' bikes (the height of the top tube from the ground) is usually two inches greater than the wheel size. In this case the standover height would be 26 inches, as the wheel size is 24 inches on the Diamondback Podium. The best bet is to measure the rider's inseam with shoes on. Once you have that measurement, simply subtract 2 to 4 inches from the inseam. If that number is greater than 26 inches, the size of the bike should work. The bike is the correct size if your child can comfortably get on the bike and stand with his feet on the ground.
