Firmstrong Bike Size Chart
Size chart and fit guide for 2026
Continue researching this bike brand
Firmstrong sizes its beach cruisers by wheel diameter rather than seat-tube length. Each adult model uses one 26" frame size with 3-4 inches of seatpost adjustment to fit riders 5'2" to 6'2"; tall riders or those wanting a more stretched-out chopper feel size up to the Urban Deluxe or Chief forward-pedal frames. Kids' Bruiser and Urban models step down to 16" and 20" wheels and are picked by the child's height, not their age.
