A power bike is for several intents and purposes a normal everyday bicycle that has been equipped having an electric motor to help in its propulsion. These motors are, limited by Federal Law, to 750 watts of power and 20 miles each hour top speed.
Most electric bikes are made to meet that specification but some do exceed them. Electric bicycles can be built from kits for around $500 to $800 dollars or purchased new for between $400 to $3500 dollars. As with any product and especially a vehicle, you always get everything you pay for. Electric bicycles are powered by a rechargeable battery(s), and the average range is around 20 miles. The range may vary greatly with respect to the weight of the bike and rider, wheel size, type of riding and terrain. They can be found in a wide variety of styles and sizes from small electric folding bikes with 16 and 20-inch wheels for commuters and apartment dwellers to 28 inch and 700c sizes. Electric bicycles require no licenses or insurance to operate but many states do have age limitations.
The most typical kind of motor used in electric bikes is a center motor. These can be used on either the leading or rear wheels and do not require chains, belts or gears. Essentially the motor is the hub of the wheel and contains two concentric rings of opposing electromagnets. When power from the battery is placed on the motor the opposing magnetic force causes the wheel to spin. This type of motor is practically completely silent and requires no maintenance. The larger the wattage of the motor, the more power it provides. One caveat however. There’s no standard for measuring wattage. Many marketers of the products use their peak output numbers rather than the operating output numbers. A motor rated at 1000 watts peak might be a 500-watt motor in its standard operating output. Be sure to learn which. Only standard operating output is actually comparable little-dragon-bikes.eu/es/.
Batteries will also be extremely important in regards to these products. The most typical battery sealed lead acid (SLA) is the most affordable and provides the greatest amp hours (ah). However, SLA batteries weigh 3 times just what a lithium battery does and last less than a third as long. A Lithium LiFePO4 battery is probably the most expensive battery and has low ah, but is by far the lightest weight and longest lasting. You would need to purchase, install, and dispose of 12 12volt SLA batteries before you come close to the life span of one 48 volt LiFePO4 battery. Nickel cadmium and other batteries fall somewhere in between. A lightweight lithium battery usually slides from the battery rack for quick recharge indoors as opposed to having to locate an outlet in which to plug the whole bike. Lithium batteries are by far probably the most ecologically friendly of all the batteries available.
The electric bikes built from kits are very often your very best bet with regards to price and performance. All of the bicycles that folks already own are superior machines to many of those which were designed as electric bikes. If you choose your kit carefully you will receive a stronger motor, better battery, and many other features that you can’t find on a factory built bike and your converted bike will often weigh less. A great kit must have the motor pre built into a wheel (a front wheel kit is significantly simpler to install), dual brake motor cutoff, a perspective or thumb throttle, a motor controller, wiring harness, and a battery mounting rack with a lock mechanism.
An excellent kit may also have wiring diagrams, mounting hardware, wire ties and complete instructions. Extremely expensive factory built electric bicycles tend to check a lot more like motorcycles, are very heavy and hard to pedal but go no faster or farther than an inexpensive bike or kit built bike. They do look cool though! Also, you may wish to purchase your kit from somebody who will be able to help you through the installation process in the remote case that you’ve a concern or problem. In the event that you are going to convert your existing bicycle, make certain that it’s good operating condition and if you are going to build a cycle from a kit of 500 watts or more, work with a bike with a material front fork. Very powerful front wheel motors can pull free from or damage aluminum and suspension forks. You don’t require a lot of gearing in a power bicycle unless you are going to put it to use as a mountain bike. For street bikes, six or seven gears are more than sufficient. If you choose to purchase a factory built bike, find one you able to completely control, feel comfortable riding and that has all of the options you’re looking for.
Having an electric bike you can pedal independently of the motor, pedal with the motor for extended range and exercise or use power alone. They’re almost silent, require no fuel and tune ups, produce no emissions and can often be ridden where other motorized vehicles are prohibited. You are able to take a power bike anywhere a typical bike is allowed including on many subway and bus systems, bike trails, and bicycle lanes. Electric bicycles can be stored indoors, something that can not be completed with liquid fueled vehicles.
Anyone that may ride a bicycle can ride a power bike and anyone with basic tool skills can install a power bike conversion kit. For individuals who have difficulty with two wheeled bicycles, you will find adult electric tricycles and conversion kits for adult tricycles as well. These operate the exact same way and will help provide excellent transportation choices for seniors and handicapped.
Electric bicycles are genuine green transportation. They can provide very real alternatives to the automobile for short range use and help relieve traffic congestion, air pollution, dependence on imported fossil fuels and give you a little exercise while going about your daily life. It won’t solve our problems but it’s a good start.
