I cut the little tab off an alfine one designed for vertical dropouts, the wheels is running at a bit of an angle after 11,000 miles because they're not that good quality.
That's not true they have a freewheel like in the rear cassette on most bikes. Their newer motors have what I believe is a more reliable freewheel system.
I have 11,000 miles on my Bosch Classic which also has pawls too.
I agree, that is why I put the question mark, as in measure the actual external width, it was a wild guess on my part, have to say I'm amazed they fit such wide tyres to such narrow rims. Still happy with my advice on tyre sizing though.
2" is still huge and will fit. If it were me I'd go to 1.5" or less. Don't buy a tyre narrower than the width of your rim which I'm guessing is around 30 to 35mm wide? Look at the weight of the tyres when choosing.
From the Conti range something like this in 1.3 x 26, there will be lots of other options from other manufacturers.
Edit, These are really light https://www.chainreactioncycles.com/schwalbe-durano-raceguard-folding-tyre/rp-prod175547
or these...
I run these on my hybrid in a 700 28 size, my bike came with chunkier tyres and these made the bike a fair bit faster and easier. I find the grip really good in all road conditions. https://www.conti-tyres.co.uk/commuting-touring/contact-ii
L-shaped brackets attached to those rear facing lower mounting holes, and a bolt into the threaded hole on the rear of the fork bridge.
Although if you're using the bike for serious off road stuff and lots of mud they won't be suitable, I had thought the bike was a hybrid, but see it is more...
Dependant on the shape of the bars it is simply a case of moving the brake levers and gear changer inwards a little, remove the grips, cut off the end of the bars by the amount you've moved the levers and then refit the grips.
As a starter go with the 16T rear sprocket https://www.ebay.co.uk/itm/Shimano-Alfine-Nexus-Single-Cog-Rear-Sprocket-for-Internal-Hub-Gears-16T-23T-/192364744818
Then if you need more change the front one too, the system won't be affected by the change.
I tweaked every spoke on my friends Orbea Gain whilst she was in the supermarket, took me about 10 minutes, every spoke was loose and the rear wheel was tinkling as she rode, wheels have been fine since.
The Orbea Gain I tried was a nice low assist bike, full power climbing power I would say is less than half power (tour mode) on my old Bosch Classic so well below the tour on your CX motor. From what I've read the Evation motor gives similar assist to the Orbea.
