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