Legos? Heck, I still remember my 'Lincoln Log' building days!

They forgot a grill & air-inlet for the engine's radiator.

It's electric... and a small electric, at that: Toyota Camatte 57s: Another Car Built Just For Kids - Rumor Central

My parents never gave me a 'toy' like to drive around in when I was a kid...just call me "...tricycle Ted..."

Dang spoiled kids these days. 'When I was a kid story'; built go-karts with cannibalized tricycle parts, nuts & bolts and twine. Those downhill races were awesome, crashes spectacular and rubbed dirt on our scratches/lacerations. If only we had Utoob back then.

Yeah, I remember building my own "powered" THING: A 3' x 4' piece of 3/4" thick plywood, with a 2" x 4" board bolted to one end and an old Briggs & Stratton 'side-crank' lawn mower motor bolted onto the other end.

The "clutch" was a 3-pully V-belt. tension arrangement. Push the board holding the front pully forward, tightening the V-belt around the motor pully and pully bolted to the inside of right rear wheel, and off you went.

Steering was with your feet; push the front-axle board to cant the front wheels left or right.

Brakes? Who needs brakes when you're young & immortal!
