Folding bike, lightweight with 20" wheels and aluminum frame, and a 7-speed drivetrain to help get over the hills. - Rider Height: 4'9" to 6'1" - Rider Weight: 230 lbs. (105 KG)

The world's most comfortable step-through bicycles just got more comfortable. Featuring super high-volume balloon tires with a rounded contact surface, the Biria Easy Boarding Balloon-7 has all the cushion and shock absorption of a cruiser without the rolling resistance. The balloon tires on this model reduce the vibrations to the back and lumbar areas by around 25%.  At the same time, due to the shape of the balloon tires, they roll more easily than standard tires. The balloon tires inflated to a tire pressure of 25-30 psi will perform like a full-suspension bike, but without the complexity and extra weight of a full-suspension bike. In other words, comfort AND efficiency in five colors.
