It doesn't need to be tuned. The only recommended tweak for mine was to check for annual firmware updates.


> aren't those gears going to be lubricated? And what keeps the lubricant off the circuit board?

It's a dry box, there is no oil bath. The gears and clutch are greased and the shafts ride on sealed ball bearings.


> And how does the lubricant get renewed or changed?

By removing the side covers. Maybe the tech at my Trek dealer was joking [or maybe not] when he said to come back in 30K miles for a Steps service.

The Steps is better built than my Makita electric drill and compound miter saw, and those have been running fine and tortured for 10+ years. I think the bike will go through a lot of chains, clusters, brake pads, tires, etc, before the power unit croaks.


This guy couldn't resist disassembling his Steps unit. The chatter is Dutch, but you can still see the internals with the sound off. https://tinyurl.com/y9hsmare
