A power bike is for all intents and purposes a standard everyday bicycle that has been equipped having an electric motor to assist 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 built to meet up that specification however, many do exceed them. Electric bicycles may be built from kits for approximately $500 to $800 dollars or purchased new for between $400 to $3500 dollars. As with any product and especially a vehicle, you usually get what you pay for. Electric bicycles are powered by way of a rechargeable battery(s), and the typical range is around 20 miles. The product range can differ greatly with respect to the weight of the bike and rider, wheel size, design of riding and terrain. They can be found in a wide selection 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 common form of motor used in electric bikes is a center motor. These may be used on either the leading or rear wheels and do not require chains, belts or gears. Essentially the motor may be 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 kind of motor is practically completely silent and requires no maintenance. The higher the wattage of the motor, the more power it provides. One caveat however. There’s no standard for measuring wattage. Many marketers of these items use their peak output numbers as opposed to the operating output numbers. A motor rated at 1000 watts peak can be a 500-watt motor in its standard operating output. Make sure you discover which. Only standard operating output is really comparable.
Batteries may also be extremely important in regards to these products. The most common battery sealed lead acid (SLA) may be the least expensive and provides the best amp hours (ah). However, SLA batteries weigh three times what a lithium battery does and last less when compared to 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 will have to purchase, install, and dump 12 12volt SLA batteries before you come near to the life span of 1 48 volt LiFePO4 battery. Nickel cadmium and other batteries fall somewhere in between elektrische fiets. A light lithium battery usually slides from the battery rack for easy recharge indoors rather than having to locate a store where to plug the entire bike. Lithium batteries are by far probably the most ecologically friendly of all the batteries available.
The electric bikes built from kits are quite often your absolute best bet in terms of price and performance. The majority of the bicycles that folks already own are superior machines to a lot of which have been designed as electric bikes. If you choose your kit carefully you will receive a stronger motor, better battery, and many other features that you cannot find on a factory built bike and your converted bike will often weigh less. A great kit should have the motor pre built in to a wheel (a front wheel kit is a lot simpler to install), dual brake motor cutoff, a twist or thumb throttle, a motor controller, wiring harness, and a battery mounting rack with a lock mechanism.
A really good kit will even have wiring diagrams, mounting hardware, wire ties and complete instructions. Very costly factory built electric bicycles tend to appear similar to motorcycles, are extremely 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 someone who will be able to assist you through the installation process in the remote case that you have a question or problem. If you are likely to convert your existing bicycle, be sure that it is good operating condition and if you are likely to build a bike from an equipment of 500 watts or maybe more, make use of a bike with a steel front fork. Very powerful front wheel motors can pull free from or damage aluminum and suspension forks. You may not require a lot of gearing in an electric bicycle if you don’t are likely to use it as a mountain bike. For street bikes, six or seven gears are far 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.
With 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 can take an electric bike anywhere a typical bike is allowed including on many subway and bus systems, bike trails, and bicycle lanes. Electric bicycles may be stored indoors, something that cannot be completed with liquid fueled vehicles.
Anyone that could ride a bicycle can ride an electric bike and a person with basic tool skills can install an electric bike conversion kit. For individuals who have problems with two wheeled bicycles, there are adult electric tricycles and conversion kits for adult tricycles as well. These operate exactly the same way and will help provide excellent transportation options for seniors and handicapped.
