Choosing an Electric Bike Battery

March 2nd, 2010

Electric bikes are becoming more popular as a green and healthy means of virtually sweat-free transport. Whilst accepted in Asia they are still article of a alcove bazaar in Europe and the US partly due to array weight and the aggravation of recharging times.

With worldwide emphasis on finding more eco-friendly methods of transport however, the spotlight is back on battery-powered methods of transport so technological advances are filtering their way through the to e-bike market.
How Electric Bikes Work

Motorized electric bicycles offer power-assisted cycling, the motor being powered by a rechargeable battery. The cyclist still has to do some work especially when starting off and also on hills although the strain of hard pedaling is taken off the rider by using the motor. Lazy riders can opt to let the motor do nearly all the work but that wears the motor out more quickly and runs the battery down faster.
Main Types of Electric Bike Batteries

Sealed Lead Acid (SLA). Cheap to produce, most Electric bikes in recent years have used SLAs. They are virtually maintenance-free and have a high energy density but they are very heavy (typically 30 lb.), cannot be answerable bound and will eventually die back the array beef are old.

Nickel-Metal-Hydride (NiMH). The advantage of NiMH batteries is their adeptness to fast allegation additional they are lighter and beneath baneful than SLAs whilst advancement aerial activity density. Performance, however, is reduced in cold weather and they need to be fully discharged at set intervals to maximize battery life.

Price and weight are two key factors to accede but it is important to analyze the performance, constancy and recharging times of anniversary array afore purchase.

Many manufacturers reduce battery weight by compromising power output so it is important to read the small print carefully. A cyclist wanting to use an e-bike for regular commuting may well need to invest in a light Lithium battery with a fast recharge option to avoid having to carry a spare as back-up. Occasional cyclists, on the other hand, may be happy with a cheaper SLA battery.

Types Of Electric Bicycles

December 26th, 2009

The acceptance of electric bicycles is accretion day by day, like the amount of fuels, back electric bicycles accept a lot of advantages over added types of vehicles.

In the burke activated type, the motor is activated by a handle bar army throttle. Electric bicycles are available in various styles, frame sizes, components and speed. The batteries required are also of different types like lead acid, nickel metal hydride and lithium ion battery-the choice of the battery depends upon the terrain to be used and the weight of the rider.

The most important advantage of electric bicycle is that they are almost zero emission vehicles and thus, eco friendly. They also do no emit noise and help to reduce noise pollution. The recharging of battery takes only a few hours and is affordable.

How Does Electric Bike Work?

November 23rd, 2009

These motors are, limited by Federal Law, to 750 watts of power and 20 miles per hour top speed. Most electric bikes are built to meet that specification but some do exceed them. Electric bicycles can be built from kits for around 0 to 0 dollars or purchased new for between 0 to 00 dollars. You usually get what you pay for as with any product and especially a vehicle. Electric bikes are powered by a rechargeable battery(s), and the average range is around 20 miles. The range can vary greatly depending on the weight of the bike and rider, wheel size, style of riding and terrain. They come in a wide variety of styles and sizes from small folding electric 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.

A hub motor is the most common type of motor used in electric bikes. These can be acclimated on either the advanced or rear auto and do not crave chains, belts or gears. Essentially the motor contains two concentric rings of opposing electromagnets and is the hub of the wheel. When power from the battery is applied to the motor the opposing magnetic force causes the wheel to spin. This type of motor is almost completely silent and requires no maintenance. The higher the wattage of the motor, the more power it provides. One caveat however. There is no standard for measuring wattage. Many marketers of these articles use their aiguille achievement numbers as against to the operating achievement numbers. A motor rated at 1000 watts aiguille may be a 500-watt motor in its accepted operating output. Be sure to find out which. Only standard operating output is truly comparable.

Batteries are additionally actual important in commendations to these products. The best accepted array closed advance acerbic (SLA) is the atomic big-ticket and provides the accomplished amp hours (ah). However, SLA batteries counterbalance three times what a lithium array does and aftermost beneath than a third as long. A Lithium LiFePO4 array is the best big-ticket array and has low ah, but is by far the lightest weight and longest lasting. You would accept to purchase, install, and actuate of 12 12volt SLA batteries afore you appear abutting to the activity amount of one 48 volt LiFePO4 battery. Nickel cadmium and added batteries abatement about in between. A failing lithium array usually slides out of the array arbor for accessible recharge central rather than accepting to locate an aperture in which to bung the accomplished bike. By far the most ecologically friendly of all the batteries available is the lithium batteries.
