Heh heh, watch those unexpected wheel lockups. I'll never forget mine when I fumbled the water bottle into the front forks.
Some of those bikes have a lot more clearance there than you think, and yeah, he may have locked the forks. Or just set them so stiff they barely move.
Nevertheless, that bike looks to me like eventually he's going to have the wheel hit that top part of the box. mounting stuff lower, near the pedals is fine. But that one has taken up space too close to the head tube for me to want to ride it.
Re the noobs comment. Probobally 90% of new guys to ebikes just want 1000 watts. But there are guys with good mechanical skills that go straight to welding a custom frame for a velomobile, or whatever, and want 3000 watts right away. It's our duty to put out info, what worked for me, what didn't work for me, etc so they can make their own decisions.
It's not our job to decide, "this is too dangerous for you". It is our job though, to let em know what is dangerous, like charging lipo unattended while we sleep or are in class or at work. Not saying you can't charge unattended at all, just saying do it in a smart place, preferably off the bike if you don't want your bike on fire.
