An electric bike is for all intents and purposes a normal everyday bicycle that has been equipped by having an electric motor to assist in its propulsion. These motors are, limited by Federal Law, to 750 watts of power and 20 miles per hour top speed.
Most electric bikes are designed to meet up that specification however many 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 typically get what you pay for. Electric bicycles are powered by a rechargeable battery(s), and the common range is just about 20 miles. The range can vary greatly depending on the weight of the bike and rider, wheel size, type 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 work but many states do have age limitations.
The most typical kind of motor used in electric bikes is a heart motor elektrische fiets. These can be used on either the front 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 nearly completely silent and requires no maintenance. The bigger the wattage of the motor, the more power it provides. One caveat however. There is no standard for measuring wattage. Many marketers of these items use their peak output numbers rather than the operating output numbers. A motor rated at 1000 watts peak may be a 500-watt motor in its standard operating output. Make sure to learn which. Only standard operating output is really comparable.
Batteries are also essential in relation to these products. The most typical battery sealed lead acid (SLA) may be the most inexpensive and provides the highest amp hours (ah). However, SLA batteries weigh 3 x exactly what a lithium battery does and last less than the usual third as long. A Lithium LiFePO4 battery is the absolute most expensive battery and has low ah, but is by far the lightest weight and longest lasting. You would have to purchase, install, and dump 12 12volt SLA batteries before you come close to the life span of 1 48 volt LiFePO4 battery. Nickel cadmium and other batteries fall somewhere in between. A lightweight lithium battery usually slides out from the battery rack for easy recharge indoors as opposed to having to find an outlet where to plug the complete bike. Lithium batteries are by far the absolute most ecologically friendly of all the batteries available.
The electric bikes built from kits are very often your very best bet when it comes to price and performance. Most of the bicycles that individuals already own are superior machines to many of those which were designed as electric bikes. If you select your kit carefully you will get a better motor, better battery, and a great many other features that you can’t find on a factory built bike and your converted bike will often weigh less. An excellent kit needs to have the motor pre built into a wheel (a front wheel kit is much better 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 great kit will 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 a cheap bike or kit built bike. They do look cool though! Also, you may wish to purchase your kit from someone who will have the ability to assist you through the installation process in the remote case that you’ve a concern or problem. If you will convert your existing bicycle, make certain that it’s good operating condition and if you will build a bike from a system of 500 watts or even more, use a bike with a metal front fork. Very powerful front wheel motors can pull free of or damage aluminum and suspension forks. You may not require lots of gearing in a power bicycle if you will put it to use as a mountain bike. For street bikes, six or seven gears are far more than sufficient. If you select to get 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.
By 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 are almost silent, require no fuel and tune ups, emit no emissions and can very often be ridden where other motorized vehicles are prohibited. You are able to take a power bike anywhere a regular bike is allowed including on many subway and bus systems, bike trails, and bicycle lanes. Electric bicycles can be stored indoors, something that cannot be completed with liquid fueled vehicles.
Anyone that will ride a bicycle can ride a power bike and a person with basic tool skills can install a power bike conversion kit. For those who have problems 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 might help provide excellent transportation alternatives for older people and handicapped.
