I followed my 8YO around the property for 45 min today. His version of technical riding is maneuvering around a whole slew of obstacles like a wiffle ball bats, pumpkins, soccer and footballs, safety cones, picnic bench, horse pits (w/o stacks), trees, Mom's car, rocks, shed, trampoline. We had a blast. Then we cooled off and talked about the ride while passing the football. It sure beats sitting on the deck w/ a beer.
Suggestion - buy a ride bike and ride together
