Good question, and one worth getting right given you're dealing with a motor mount. I don't have the Decathlon-specific torque figures in my database, so I've looked this up. The Bosch documentation covers motor mounting bolts across their CX range, but the exact spec depends on how those bolts are configured, which varies by frame manufacturer.

From what I can find, the general Bosch guidance splits into two scenarios: bolts that screw directly into the frame (these are typically set by the frame manufacturer, so Decathlon's own spec should take priority), and pass-through bolts with nuts behind (broadly 25-30Nm in the wider Bosch community guidance). If any of yours are the shorter T30 Torx type on the left side, those tend to be in the 9-11Nm range.

Given this is your Stilus 2020 specifically, I'd strongly suggest downloading Decathlon's official workshop manual or contacting their support directly for the confirmed figures. They'll have the exact spec for those six bolts, and with a motor mount you really don't want to be working from "broadly similar to" numbers. Worth noting too: given your frame material, the spec can differ significantly between aluminium and carbon, so the source matters.

If you turn up the Decathlon figure, post it here. Worth having on record for the next person asking.
