  1. Flat Foot Technology® allows kids to sit upright and plant their feet flat on the ground without ever leaving the saddle, which means no tippy-toe stops and a wide view of the road so they can see what's coming.
  2. Dual position crank arm allows the bike to grow with kids.
  3. Adjustable pedal mount positions accommodate growth spurts.
  4. Schwalbe Big Ben puncture-resistant tires with Kevlar® Guard protect them against flats to keep them riding all day.
  5. Designed as a universal, aluminum frame and built to last so this bike can be passed down to siblings.
  6. Accessorize their new ride with a custom Electra bell or handlebar bag to carry all the necessities.
