I recently made some mods to my drivetrain and wanted to share this one in particular. I wanted to be able to cruise just a bit faster while also putting in just a bit more effort. To do that, I replaced the front crank with a 46 tooth sprocket (from the stock 42, so it required me to replace the chain as well but that's a maintenance piece anyway).
Of course I had to fool the controller so I changed the setting for the wheel size to be one size down, so it still provides a bit of assist when I'm cruising at this slightly faster speed.
I've only taken a short test ride but so far so good!
