Day 2: spent a couple hours trying and failing to adjust the disk brake. I'll get it... I hope.

Also removed the cranks, bottom bracket, and so forth to install the torque sensor (which replaces the bottom bracket). Unfortunately, I don't have a chainring that'll fit this setup, and I forgot to order one earlier, so more wait...

I also modeled up a way to mount the display near the front of the bike.

Close up of the front boom of my recumbent e-bike. A new bottom bracket with integrated torque sensor is installed. The chainring mount and crank arms are sitting on the stand, waiting to be installed. Which will happen after the new chainring arrives.

@younata Wow that looks amazing! I had been wondering if an electric assist recumbent bicycle was feasible. I converted a recumbent trike to electric.

Always wondered if a two wheeler recumbent electric would have balance problems. I only tried a recumbent 2 wheeler once and couldn’t really get my balance to work 🤪

What are you using for the Controller? I used the Grin Tech Cycle Analyst and Phaserunner with torque sensor.
Had written up the original work at https://endless-sphere.com/sphere/threads/my-experience-converting-an-ice-trike-to-a-dd-hub-pedalec.91440/

Rear view of the 2012 Ice Recumbent Trike modified by myself to add electric assist. Can see the Crystalyte M3540R hub motor. Two - 52V 13 Ah Downtube Battery. Upfront you can see the Cycle Analyst V3 console. Also has torque sensor in the bottom bracket, as well as a throttle and brake sensors. Also switched to Magura MT5e 4 Piston Hydraulic Disk Brakes

@rberger @younata
HP offers 2 wheeled¹ #recumbents w/ e-assist since ages; nowadays even as S-Pedelec…

¹ trikes also, of course
