Electric Bicycles and Electric Power Assisted Bicycles offer many advantages to commuters providing low cost transportation around town. Since these are the bikes which are not too powerful, it is classed as a bicycle. Electric bicycles carry rechargeable batteries which can be charged with mains electricity or from renewable sources such as solar and - or wind power, and so they are very cheap to run. Electric bicycles cope well with hills and carrying a lot of luggage. There are two main types of electric bicycle: those with a separate throttle on the handlebars which are called E-bikes and those with pedal sensors called pedelecs to match electric power to the effort you are putting in. Much lighter bikes are also available starting at around 20kg for a 16" wheel model with battery, or even less for a more expensive lithium ion battery and folding aluminium frame. Electric bicycles weigh less than 40kg and are not rated over 250 Watts, powered speed is 16mph or lower, the bike has working pedals, and riders are over 14 years old. It is not necessary to wear a motorbike helmet when riding an electric bicycle. If the bike is too heavy, too powerful, or too fast then it is classed as moped and must be taxed and insured etc. Electric bicycles can climb a hill without any help from the rider. A twist grip throttle is used to control speed. Power-on-demand bikes are often a bit heavier because of the more powerful motor and battery. Although capable of pushing you along without your help, electric bikes perform noticeably better when you pedal, especially with the 24v models. The average electric bicycles can range up to 25 miles with minimal effort, with a recharge time of several hours. Power, when activated by a switch on the handlebar (power-on-demand) or in response to your pedaling, gives you an immediate, nearly silent push. When you release the switch or stop pedaling, the motor coasts or "freewheels" like when you stop pedaling a regular bike. Standard electric bicycles have hand brakes and gearing round for the controls. "Power-on-demand" means just that - no pedaling required! This is how our 48 volt super heavy duty bikes operate. I rode these with a passenger on back for 30 miles with hardly pedaling at all! Although all electric (or "electric-assist") bikes are designed to work with your pedaling, power-on-demand allows you to break the rule.

Bernsonev E.V. is a renowned online electric vehicles dealer which sells several brands of electric vehicles including electric bicycles through internet. Most of electric bicycles from Bernsonev offer a variable speed control. If you visit their website, http://www.bernsonev.com you would find some bicycles offer through-the-gearing power assist, that is, the force of the motor goes through the bike's gearing system which provides better hill-climbing and top-end speed than direct drive systems with the same size motor.
