It was OK - pretty useful for most people that would want or need to assemble one. I give it an 8/10 for normal people, but if a bike shop did it 7/10. You asked for comments, so here's mine on the basis of how it could be improved to make it the best possible. Please don't hate me. I'm always looking at how things go wrong and how to prevent them because I've spent a lot of time dealing with the problems. It's quite a big list, but only point 4 gave me a bit of concern.
1. I didn't like the banners in the middle of the screen. I just wanted to see what he was doing. Make them smaller, transparent and/or shift them to the top or anywhere where they don't obscure the view.
2. You should have put more emphasis on the difference between the threads on the pedals between the right and the left one. That always causes confusion for people that don't know about these things.
3. You didn't do the pedals tight enough. That spanner is a bit crappy, but you should have emphasised the need to tighten the pedals as much as can be done with it by hand. When you don't tighten them enough, they come loose and ruin the threads in the cranks, so you end up with a difficult and complicated repair.
4. The screw in the cap on the top of the stem is to adjust the steering bearings. If someone just did it up tight like you showed, but before tightening the stem clamp screws, or if they didn't tighten the stem clamps enough, they would end up with weird steering. It's quite common for bikes that come in boxes not to have properly adjusted steering head bearings, so something about how to adjust them might help. Whatever, you need to explain about where and when you should tighten that screw. There's no need to do it up tight. Once the stem is clamped properly, the cap doesn't do anything other than look pretty. You can remove it and everything would still work, though it does provide additional safety.
5. Show how to charge the battery. Some batteries require the power switch to be on in order to charge. If yours is like that, say something about it. Show how to put it on and take it off the bike, and explain the importance of only putting it on the bike while the battery is switched off to avoid burning the contacts.
6. The saddle looked like it was at a strange angle - probably just the camera angle. You said you'd show how to adjust it later. I would have showed how to adjust the angle and fore and aft position there and then because everybody would want it adjusted for themselves, but most aren't even aware that you can adjust it. As a minimum, you could have explained that you can tilt the saddle and move it back or forwards and said to look in your next vid to see how. That sounds a little pedantic, but it's important for a user who doesn't know anything.
7. I would have checked the motor wheel nuts - just for security and peace of mind.
Good luck with your new bike, and I look forward to the review. When you do that review, just for me, please don't say that it has a range of x miles. Bikes don't have a range. The range depends on the rider and where and how they ride. Just explain how much charge there is in a battery, and if you go on a ride long enough to deplete it, give details of the journey, hills in particular, your fitness and weight.
