Apart from an oil refilling kit, hydraulic brakes don't need specialist equipment.

Most ebikes still use standard derailleurs (usually a 1x drivetrain).

For internally geared hubs, Nexus or Alfine IGH are the most common, and apart from getting the cable tension right, don't need any specialist equipment (though the Alfine 11 speed hub is apparently somewhat tricky because it has to be packed with grease).

Most IGH still use chains, belts are less common. Newer chains are rated for ebike use but that generally just means they're more robust.

Belt drives do need to be tensioned properly but again, this doesn't requires specialist tools nor does it require a huge amount of specialist knowledge for a bike mechanic that is (there's literally an app for that). Enviolo, Roloff and other gearbox style systems are specialist equipment and not what you would normally expect a regular bike shop to do intricate servicing on.

Also, internally geared hubs have been around for almost a century and both IGH and belt drives are used on regular bikes. You would expect bike mechanics to be able to deal with them easily.

So by and large, they really are bikes with motors. Yes, there are some things that are more complex but the majority of things are basically the same

My LBS, which is familiar with Gates belt drives, uses for tensioning a rather old-looking metal contraption provided by Gates. Definitely a specialist tool. The phone app for tensioning a belt from the frequency of the twang it makes, is only for end-consumers. Shops are supposed to use the dedicated tool.

odd-looking, not old-looking
