Fun idea! I'll echo the comments about bringing in the text all at once, or at least line by line. The characters are definitely printing out at your 60 chars/second target; it's just significantly slower than I think a lot of people read.
Some additional common parts you might consider adding:
- Rear wheel hub (cassette compatibility) and front wheel hub
- Bottom bracket (crankset compatibility)
- Axles (quick release and threaded)
- Star nut (what the top cap is generally bolted to)
And some minutia you may want to add:
- Many rear derailleurs nowadays come with a simple on/off clutch that adds extra rotational resistance to the cage arm. That helps keep it from pivoting during rougher riding and in turn helps limit "chain slap" against the frame.
- The handlebar stem is one of the most, if not the most, critical components on a bike in terms of safety. You tighten the top cap just enough to pull all of the headset components flush against each other, but the stem bolts are what actually lock the handlebars to the fork. Just something I always emphasize because I've seen too many people try to wrench the top bolt within an inch of its life, barely tighten the stem bolts, and then almost hurt themselves when their bars rotate and/or twist while riding.
Thanks for the feedback! I disabled the text animation for the time being.
There is a note about the star nut if you click on the headset top cap and then explode the headset, and I also mentioned QR vs thru axle briefly when talking about the fork. BB is definitely missing and I should add it. I was also thinking it would be fun to make the wheel explodable too, which would give me a place to talk more about hubs, spokes, rim standards, etc.
