Why you'll love it
Intuitive twist shift makes it easy for kids to switch gears when their terrain changes
You can replace the saddle's integrated handle with an integrated light mount to boost visibility on family adventures and solo excursions
This bike is hand-me-down heaven: it's built to last, so younger siblings can inherit this bike and it'll still feel like new
Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off
