@The Bear congratulations to your bike!
I commute with the 2017 bike since mid of June and I want to give my experience, maybe it's helping.
If you have no real mudguards like somewhere at the beginning of this thread, you'll get dirty. I use the mudguards in the rear (see above) and at the front (see below). My backpack it just a little dirty and I have no dirt in the face any more. The bike? Yea it's muddy every day - but when it's muddy - I'm happy
Lights, i don't want to take care about other battery powered stuff like lights or cams. So I decided to use install lights powered by the Bosch battery. In the rear under the saddle is a supernova - very bright. In the front the bike shop recommended the B&M EYC because I had a budget of just 100 Euro. For my use case it's ok - of course there are better and more expensive lights.
If you have the EMTB Software, then take care of your chain. Mine lasts only 2.500km. At 5.000km the cassette needs to be changed also (expensive!).
Would be nice if you join the
pedelecmonitor (english: ebikemonitor) and share your experience with the bike when you hit the 5.000km.
