How does elecrtic scooters work, is it safe comparing to a petrol engine?

electric scooters are still being tested and only after 2 to 3 years we will come to know about it, but in stop and go traffic i think much more technology has to go into electric vehicles

With the price of fuel, it seems this is the way to go Electric motors have been around for decades.Ssooters(electric)are safe,quiet and clean The only problem is battery life

well if you had a couple grand you can go and buy a street legal dirtbike the tank doesnt hold that much but you get great miles
