>Yeah but there’s nothing to break or fix on a Zero!
...........?
Wheel bearings, axle grease, wheel alignment, fork seals, suspension bearings, head bearings, chain/belt, sprockets, brake system (pads, piston, caliper, seals, master cylinder, fluid, rotors), tires, cooling system. Plus the classics of levers, hoses, bent handles bars or forks, stripping bolts, broken kick stands, etc. None of that goes away with an electric bike.
And you do need to do inspections on electrical connectors at minimum. Being electric doesn't solve small design flaws. Suzuki infamously made the green connector of death. The headlamps and ignition switch on the same connector, which inevitably burns out due to resistance in the connection growing due to corrosion which eventually causes it to melt. Saw a similar problem with a Kawasaki with corrosion interfering with kill switch circuit.
Not to be pedantic or invalidate your point, but most (all?) Zero bikes are air cooled, and they have zero hoses. Brakes get like an order of magnitude less wear thanks to regen, and the only fluid is brakes (well, and the battery, but if you find yourself in contact with it, the bike is a loss).
Fair enough on the cooling, but brakes I disagree, at least with my riding style.
I do most my braking with a combination of front and engine braking. I usually don't touch the rear until either I'm close to a full stop or if I'm doing slow speed maneuvers. So unless Zero's got regen on the front wheel, I don't see there being too much different between the two.
There's nothing tricky about fixing a brake, though. It's a portable skill from one motorcycle to another. Unlike, say, the tolerances for oval and taper of a cylinder.
I get that there's still going to be screws to turn on an electric bike, but that's going to be about what it boils down to: a list of torque specs.

Harder then you might think. I've seen someone not install the pads and have the rotor grind down into the caliper itself. Then installed the pad on the broken caliper and getting so crooked that it eventually warped the rotor into a dinner plate. IIRC the edge of the was about 1mm or 2mm out of line from the center of the rotor.
Swinging back on topic though, I do disagree slightly on the premise that the service manual is just a glorified page of torque specs. Speaking personally, fixing something isn't usually that difficult. Time consuming, demanding in focus, and wise to be cautious but generally speaking the procedure is usually well laid out.
What's hard is diagnosing the problem in the first place, determining what the fix is, and then locating the necessary parts or suppliers for those parts. The service manual's usually invaluable for the first bit.
Just to give a car example: You have a car who's instrument cluster who's center LCD that's stuck at minimum brightness. Is it a problem with the instrument cluster, the dimmer switch, or the PWM signal generator that controls the cluster's brightness?
As it turns out, someone thought about that. The service manual listed out a self test diagnostic for the instrument cluster; with engine off and key out, hold the odometer reset for 5 seconds, insert the key and turn to the on position. It will light up every light to full brightness and disregard the input PWM signal.
Who could have figured that out without the manual listing that procedure? I probably couldn't. I'd probably be reduced to parts cannon.
Electronics aren't immune to manufacturing defects, design flaws, mislabeled products, abuse, or the outside elements. And if something does fail, it's an absolute bitch to trace down problems with the electrical. Service manuals are invaluable both listing how things are supposed to work as well as often having extensive trouble shooting guides that give a hint at what could be a problem.
We definitely have very different riding styles. I keep the regen cranked all the way up, and I can get fifteen miles across the city without touching either brake. I'll occasionally use the rear brake for trail braking.
The regen on my Energica is definitely a lot stronger than on my Zero, though—it's a lot more like an electric car where you can keep your foot over the accelerator almost all the time.
Between the two bikes, I've got roughly ten thousand miles and all four brake pads sit at ~85%.
