Lol I wish it was just an 8 hour day.

More like 12-14 hours, and with the experience I had I was able to build most in about 6-7 minutes.

There's downsides to speed building like that, because whoever has to inspect it when it gets sold has to spend a lot longer fixing minor problems.

If I were building at my own store, each bike took about 20 minutes because I made sure everything was as close to "ready to ride" as possible.

Nowadays I bulk build for many companies. They don't give a shit about quality but I spent years making sure my bikes were perfect, so I still like to make them good to ride out the door.

my quickest bike was one particularly well put together model. 3 minutes per bike and it was good enough that I'd ride one without tools to the nearest store a few miles away.
