Definitely he is having a blast, my concern is taking my son to more challenging places, he is only six years old and I think more challenging rides can be dangerous for him regardless how comfortable he feels riding. No need to push because eventually he will be there.
My son (8) has been badgering me to take him night biking. Well the other week I took him and his sister out. We went out on a Friday night and they had such a blast we went out again on Saturday. That time I took my GoPro.
Nice shots of my 5yo son at the North Park Freeride Jam last weekend in Pittsburgh. Thanks to the helpful bystander for capturing and posting these these images in flicker. I was having too much fun chasing the boy and his sister around the dirt jumps to take any pictures myself.
That's fantastic! Blue Velvet is no small thing, especially at his age. I've started taking my 9yo to Whistler this year, he's still only riding Easy Does It but I think he's ready to tackle B Line.
Take him on Crank It Up instead of B-Line. He will enjoy that a lot more, pretty flat and lots of small jumps for him to practice on. Lukas and I were bolth really impressed with his Commencal's performance at Whistler. Here are a couple picks from yesterday at Burlington Bike Park
4 year old Tomas
Lukas now 7 hitting the quarter pipe.
