Electric bikes do not have alternators. The laws of physics prevent an e-bike from having an alternator, as it would incur more drag than lift. However, the electrical system in bikes is usually powered by a type of alternator called a stator.

Electric bikes don't have alternators because of the laws of physics
The laws of physics prevent an electric bike from having an alternator. You are free to have one, but since there is no such thing as perpetual motion (a 100% efficient machine), it will incur more drag than lift it provides. This is because, when you add extra components, you add weight, and on a bike, you notice every pound. It's more efficient and simpler to just draw power directly from the battery to power other components such as lights or the display.
Regenerative braking in any electric vehicle uses the drive motor(s) as a generator. However, regenerative braking is not particularly effective, and electricity-generating suspension won't be either.

Electric bikes use something called a stator to power their electrical systems
The stator works alongside a rectifier/regulator to convert mechanical motion into alternating current (AC) and then into direct current (DC) for the motorcycle electrical systems. The stator is much smaller and less complex than standard car alternators, which is why they are commonly used for motorcycles.
An alternator is a motor inserted in the drive line that has no electrical input. It generates electricity in the bike, which is needed to power the headlights, indicators, and the engine itself. However, the laws of physics prevent an e-bike from having an alternator.

However, the laws of physics prevent an e-bike from having an alternator. While regen braking exists, it is not particularly effective, and electricity-generating suspension won't be either. This is because there is no such thing as perpetual motion (a 100% efficient machine), so an alternator on an e-bike would incur more drag than lift.
The main reason alternators are used in DC systems like cars is that they are more efficient and mechanically much more reliable as they don't use a commutator. The drawback to an alternator for a bicycle is that they generally require high rpm to produce any significant current, typically over 1000 rpm, which on a bicycle would require gearing to achieve, adding weight and being one more mechanical thing to go wrong.

The electrical system in bikes is usually powered by a type of alternator called a stator. These are much smaller and less complex than standard car alternators, which is why they're commonly used for motorcycles. Most motorcycles have alternators that charge the electrical components while they're operating. However, the alternators found in bikes work a bit differently from the ones found in cars, due to their substantial size difference.

Alternators are a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. They convert mechanical energy from the engine into electrical energy to recharge the battery and power the car's electrical systems while the engine is running. They produce AC current by rotating magnets around a coil, which is then rectified into a DC feed for the car to use.
