The Diamondback Metric 24 is a new aluminum kids bike that’s affordable and actually available right now. With 24″ wheels running 1.75″ tires, it doesn’t quite push over into the mountain bike classification but it would certainly go well on the local bike path, pump track and even a few gravelly off-road sections.
Diamondback Metric 24 Kids Bike
Diamondback don’t specify a rider height for the Metric 24 kids bike, but this frame with its 24″ wheels and a standover height of 630mm will likely fit children aged 9+. It gets a durable aluminium frame and wheelset with fast rolling 1.75″ tires that will help your children keep up with their friends at the park.
Fitted with rim brakes, this bike could be a good option for kids who may still be learning how to brake safely. If your child still likes to grab a handful of brake it’s best to steer clear of the more powerful disc brakes until they’ve learned how to come to a safe, controlled stop.
The Diamondback Metric 24 gets a grip shift; the 1 x 7 speed Shimano Revo drivetrain will keep gear changes simple for young riders who are still figuring out how to “make it harder” and how to “make it easier”.
The Metric 24 also gets Soft Kraton Rubber grips and a padded Diamondback Jr Saddle. The cranks are 152mm long fitted with a 36T chainring protected with a dual-sided guard. The hanger that bolts the rear mech to the frame is also replaceable, so when your little one smashes it off a rock, it isn’t the end of the bike’s life.
The aluminium handlebar is 580mm wide, but that can be cut down by your local bike shop if it is still too much of a stretch for your child. The bike doesn’t come supplied with fenders but there are mounts should you need to add them for the school run.
