Take a look on any street these days and you’ll likely see a silent two-wheel bike of some sort driving by. Electric bikes, electric mopeds, electric scooters — even electric motorcycles — are everywhere.

It might be that the electric vehicle, or EV revolution, may be more about 2-wheel transportation than 4-wheel modes of transport. Here's what it takes to get on road with one of these two-wheel vehicles, and why you might prefer an electric two-wheeler or a traditional gas-powered one.

Licensing and certification

The question for most new riders is how to get into the electric bike, scooter, or motorcycle game. Requirements differ by city and state, but for the most part they follow some basic rules.

In many areas, licensing for traditional motorcycles and gas-powered mopeds or scooters has typically been based on the size of the engine. With electric bikes, the engine’s displacement is irrelevant when determining power. In the state of New York, where I live, any two-wheeler that can travel above 30 miles per hour requires an M-class — or motorcycle — license. Getting an M-class license typically requires completing a safety training course and demonstrating proficiency on a bike.

Slower two-wheelers, such as scooters or e-mopeds, don’t require a motorcycle license in New York. The manufacturer and retailer should know whether a motorcycle license is needed or not, based on location.

For most city driving, you might be able to get away with using a less powerful electric scooter or e-moped that don't require an M-class license (those Niu electric mopeds, that both Revel and Lime use are good examples). Anything else more powerful — and likely looking like a "real" motorcycle — requires the same M-class certification as more powerful gas-powered motorcycles.

Operation and maintenance - the electric motorcycle edge?

California-based Zero Motorcycles is one of the prominent makers of electric motorcycles that function and operate like your standard motorcycles.

The company has been making electric motorcycles for over 10 years, and just released its latest creation, the Zero SR. The SR is a "naked streetbike," with a powerful electric motor capable of taking the bike to 104 mph, with peak torque at a robust 122 ft-lbs, and a range of nearly 230 miles in extended form. And a curb weight of around 489 lbs. keeps it competitive with most sport bikes in its class.

So the capability is certainly there. But from an operation and maintenance standpoint, are electric motorcycles better than traditional gas powered bikes? Sam Paschel, CEO of Zero Motorcycles, not surprisingly believes that is the case — and not just because of "going green."
