Here is the build, after a few tweaks.
I've hidden the ghastly battery and wiring in a frame bag. It was so huge it almost did not fit. I may never get it out again.
The cockpit. Redshift kitchen sink bars. TRP hydraulic brakes (with Shimano calipers). SLX 11-speed shifter (11-speed long cage XT derailleur). Controller display is small compared to my Garmin 530.
