Kids bike that makes them feel big

Recently purchased this bike for my 5 year old son. He loved the blue/orange color scheme. He is getting more adventurous so he need something with better stopping power on the trail and the discs do the trick! We were a little afraid the fatter tires would be tougher for him to push on the road for our neighborhood rides, but that's not the case. He hasn't lost any speed/endurance and comments on how he loves the feel.
