Chiming in. The next morning, armed to the teeth with hope for humanity and believing in the good in Man I made myself on the way to the bike shop in my village. And I asked for two meters of gear cable housing, I received it, properly cut, in no time, and for a very reasonable price. Thanks.
So I reinstalled the front derailer, reran the rear brake cable and the Nexus gears cable.
I use a cassette joint from an older Nexus 7, which features an allen bolt for fixing the cable, which makes the installation very easy. I have the same in my electric Felt.
Then I was able to move the brake levers and the shifter further apart. I trimmed 1 cm on each side of the bars.
Cockpit area:
I was able to find the rubber grip from the right mtb shifter.
This is a magnet, by the way:
It can hold a 15/14 wrench:
I am planning to use this bell:
I put some silver nail polish on the thumb actuator.
This is the stem area:
The whole headlight carrier assembly and parts origin:
To attach to the fork leg I had to choose between the flat stem and the chrome stem - the flat stem matches the frame and the fenders. The chrome stem matches the fork and the headlight. I am still not quite sure which one to choose for a final.
Anyway, then comes the flat black stem adapter which holds the clamps for the headlight and the clamp for the fender (which clamp is from a Tacho). Those are mirror clamps for a moped. The headlight is bolted to a piece of a holder for a rear rack reflector. Which is bolted to the mirror clamps. For washers I used those pieces from the outside of a seat clamp:
There is a small plastic ring that imitates a shaft so the cap can be bolted to the stem adapter so that the spiky end is not a danger.
The flat black stem adapter and the silver acorn nuts are meant to match the flat black adjustable stem I used for the rack attachment:
And I also reworked the rear fender a bit.
Trimmed the front piece and flipped the bolts to use my signature v-brake nuts.
Actually I am a little disappointed that this taillight cage didn't work out:
So it shifts, it brakes, if tomorrow doesn't rain I will take it out for a ride and photos.
I almost forgot. I replaced the non functioning suspension seat post with this nice aluminum seat post, which compliments the rack contraption well, I think.
Then I found the valve cap from my Torch rear wheel (unfortunately it came with only one such valve cap) which I promptly bolted to the seat post bolt. "The machines rose from the ashes of the nuclear fire..."
