It's right for you if...
Your kid loves to explore, and you want them to have a quality ride for all their road, path, or trail adventures. They're ready to upgrade from a singlespeed for a little extra help on hills and longer rides, but they don't need a ton of gears just yet.
The tech you get
A strong, lightweight aluminum frame that will stand up to whatever your youngster dishes out, with simple and reliable Shimano 8-speed shifting that makes it easy to climb hills. Plus, it has a kickstand, and a saddle with an integrated handle that can be swapped out for an integrated taillight mount.
The final word
Whether your kids are riding to school, racing around the neighborhood with friends, or tagging along on family rides, Precaliber 24 8-speed features the quality parts they need to ride with confidence and stay in control.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
