He's a cool guy. He likes cars too, which put him in my cross-hairs well before the subscriber explosion. I only wish I had his charisma and appeal. He got his old bike back because someone (not him) started a fundraiser to make it happen. And it did. I'll be stuck saving for a year before I can buy a bike, but I am fine with that. It's so much fun looking at all the different bikes I could end up with in the future! The Honda 919 is on the top of the list currently.
But you are right, he is doing it for fun. He would have put out the same content if he was still small. The same goes for myself. I post my stuff to YouTube because I want to have fun and connect with like-minded individuals! No matter where I go, stay at 1,2k or get to 100k subs, I am not magically going to get a chip on my shoulder and change everything up to highlight my awesomeness. I'll still be posting here, and still be interacting with everyone I can!
The key to his succes is shoutouts. I got some in the past, when 6foot4honda was at 10K subs, and adjriannickelodeon as well. I shot up overnight. It's relative, but if I gain 25 and 47 subscribers in a day it's insane, most recently I got a 27 gain from my "I got my motorcycle licence" reveal in an EN187 livestream.
The motovlogging community is awesome, to those with bikes, and those that desperately want one (or just support the 2 wheel lifestyle!). How can you explain motovloggers giving a shout-out to a guy that drives a car (aka, a cager) on his channel? I surely can't.
