Jump Bike Size guide
Jump bikes are designed and intended for Dirt jumps, street and skatepark riding. Not for riding any distance.
They primarily use a 26” wheel with the frame only available in one size, to suit riders taller than 4’5” or 137cm.
Some manufacturers offer a long or short length bike. Riders over 5’10” or 178cm will prefer the longer option.
