Rethinking Kids Bikes

9 out of 10 bikes are sold in mass-market stores where design is based solely on price. Our focus is on safety and giving your child the best experience possible.

  • Cheap Brakes

    Not reliable, slow-reacting brakes should NOT be an option.

  • Heavy

    A heavy bike leaves your child tired and frustrated with little control and balance.

  • Unsafe Setup

    Bikes are put together by untrained employees with little to no bike education.

  • Poor Experience

    Parents are left uneducated with unanswered questions and concerns.
