BBS 02 upgrade to Surly Ogre with Rohloff hub

I just had a Bafang BBS02 750w installed on my 10 year old Surly Ogre - originally built for touring with a Rohloff internally geared hub.

I moved to a very hilly region some years ago and just wasn’t using my bomb-proof - but heavy steel framed Surly. After the electric motor upgrade it tackles hills easily and I’ve effectively got a new bike using the original build (at half the price of a new one) I’m glad I upgraded and didn’t purchase a new off the shelf e-bike.

Also thanks to this feed for the many stories of upgrades that helped me decide.

Hacking a Rohloff E14 2.0 to work with Bafang M315 (CAN-bus)? Looking for "Shift Sensor" bridge advice

Hi everyone,
I’m currently building a custom cargo bike from the ground up and I’m at a crossroads with the drivetrain. I’m using a Bafang M315 (MM G340.250.C, 48V/250W) mid-drive. It’s the newer CAN-bus variant, which I’ve used on several builds and really like for its reliability.

The Goal:
I want to pair this with a Rohloff Speedhub, but because I’m routing all my brake lines and wiring internally through the frame, I really want to avoid the mess of mechanical shift cables. The Rohloff E14 2.0 electric shifter is the dream—it would make for a much cleaner build.

I know Rohloff recently released the E-14 2.0 DS BAFANG, but documentation is sparse for installing with the Bafang motor. Specifically:

My M315 has the dedicated 3-pin yellow shift sensor plug. Is this compatible with the product?
Does the 3-pin shift port on the Bafang provide enough juice to power the E14 actuator?

Any insights from the Rohloff/Bafang experts here?

Oil leaking from shift unit?

The shift unit screw came loose (big thumb screw) and when I went to tighten it back I noticed a load of oil on and around it. I changed the oil in the unit five months ago but I don’t see any oil near the screw through which you change the oil.

Any ideas what’s up?
