I selected the Radio Flyer Ultimate Go-Kart, 24 Volt Outdoor Ride On Toy because out of all the options for Power wheels style ride on toys it had the the following features:


1. Good build quality (metal frame)
2. very fast, 3 speed shifter, capable of drifting and peeling out.
3. simple electronics bay, room for upgrades


  1. lighting - add 80W LED white light to front and rear red running lights
  2. replace X2  12VDC series (9Ah) SLA batteries with DIY 7S6P 18650 lithium ion pack (15Ah).
  3. Add DC power distribution fuse box
  4. add battery fuel gauge
  5. remote kill switch, RF controlled relay
