For those who enjoy the use of the rear brake, either for slow speed maneuvering, or high performance control while at lean angle, left hand rear brake is a great tool.
I used a Qnium rear master and a Magura left hand hydraulic master, connected by a brake line. Stock brake pressure banjo switch and stock rear brake lines were reused.
Rear brake pedal functionality is maintained.

Interesting video by a moto GP rider on how they use rear brake:

Not posting much on the owners group on Facebook.
I find it to be hard to use compared to the Forum style.
I also find the information is not as helpful as that found in the forums. Just my opinion.
Too much fan loyalty or excessive criticism to be helpful. In general. Again, just my opinion, and full respect to those who maintain it.
This forum is great. We just need a few thousand more members.

Another pic of the dual port rear master:

How much did you spend on all the parts?
Do you ride ICE bikes too? So you find difficult to switch from clutch to brake on that lever?

Yes, I ride ICE. Track and street.
Left hand rear brake on all my bikes. Hypermotard, Tuono, R6, Grom.
It takes little time to adjust to having a clutch and brake lever on the same bar. Most the bike have quickshifters, so I only use clutch for getting into first gear.
It cost about $600 in parts, but can be done for less if you source alternatives. A vacuum bleeder is a big help.
Once you get used to having the additional control, you will feel uncomfortable riding any bike without it. Downside to consider.

You could use a junction block for the existing Brembo master. Not as effective.

I just use the regen for most of my braking TBH. I do find the rear brake position by the foot rest a bit.. annoying TBH. If I find myself in a hard braking situation, half the time the feet are already down waiting for the spring back off the front shock to catch the bike. Maybe I haven't ridden enough but find that I almost never really use the rear brake. Once you get used to the regen you can pretty much feather that to control your stop or turn.

Pace and direction.
Agree that the regen is almost a substitute for the brakes. At a comfortable pace, you can pretty much control your speed with throttle alone.
The need for more brake becomes an issue as the pace picks up. Going along a bit more quickly on the straights increases reliance the brakes to get slowed and pointed in and out of the corners.
Control of direction, setting and adjusting the line when ON the throttle midcorner, or on exit, can be overlapped with rear brake for directional control adjustment. You can be opening the throttle to wide open and using rear brake (never the front) to help steer.

Not the street, but watch how much rear brake gets used to control the bikes direction:

Rear brake is also for better control at low speed (< 7 km/h). You operate the brake against a constant push from the motor. Tremendous effect!
With regen alone that is not working as good (my experience).
There are lots of vids on Youtube, e.g. with topic of how to do a tight u-turn in one go.

This video is from my morning ride.
You want the full use of front and rear brake. This slowdown required full fork compression with heavy front and rear brake use, modulated by hand, while at lean angle, to avoid hitting a deer. The deer did not have as well developed a skillset, and lost traction ... ;D

Not to dredge up the past, but Pard am I correct in undertsanding your setup on the Energica is essentially a new lever with reservoir, plumbed down to the existing foot brake location, and the existing master cylinder replaced with a multiport one?
As for Qnium link you posted, which version did you opt for? Any tips for the brake line routing?

Exactly as you described.
I used a unit that had both ports on the rear, because I had it on hand, and used an adapter to mount the line on top. Not ideal.
Use a unit that best fits the lines and routing you plan to use, just make sure you order one with mounting holes compatible with the Energica mounts (I belive 40mm).
I ran the line along the right hand frame, inside the frame, next to the battery. Depending upon which set of hand and rear masters you use, order a custom line with banjo fitting that are a perfect match and a line that is exactly the length for the routing you decide to take for the line. I used one I had on hand so I needed an adapter at the qunium master.
Give them a call or email them. Very helpful bunch.

Ive been toying with this idea for a while. I really like the idea of having the brake in your hand and not having to fiddle with your foot.
with a little tuning to it's setpoints, you could almost just use regen as a rear backe, I mean if you were to get it to where it'd hit hard enough to just be at the edge of stopping tire rotation that'd be the same as a hard braking. In reality even with braking you don't want to lock them up, your ABS will take care of that of course but. Wish there was a way to get my regen to hit even harder than it does. The EGO race bike now it'll push you forward, Ive had a few racers tell me, man that things shoving half your body weight forward! So itdoes work, just would like a little more !
