The 36V Electric Bicycle Lithium Battery Has Changed The Future Of Bicycling

By Leslie Ball


The numbers of people riding bicycles has expanded exponentially in some cities. While not a practical option for all, it has become a popular alternate form of transportation for short urban trips, and the personal health benefits are undeniable. Uneven or steep terrain can become challenging, and results in many riders choosing bicycles enhanced by a 36V electric bicycle lithium battery for additional pedal power.

The concept is not new. Patents for similar vehicles were being issued prior to the beginning of the 20th century, but like many types of electric transportation, were eclipsed by the rise of the personal automobile powered by gasoline. Modern technology has given e-bikes a boost, and increased awareness of environmental concerns make them a practical and serious alternative in many locations.

These vehicles are different from the bikes that dominate many childhood memories. While they resemble standard two-wheelers, most are considerably heavier. The extra weight includes a battery that is by far the costliest component, exceeding the value of the frame and motor combined, and relying on technology that has not yet been perfected. Cost per mile after purchase is extremely low, but getting started can be a comparatively expensive undertaking. .

Models from a few years ago often featured heavy lead-acid batteries, which add weight and can make riding cumbersome. Lighter power packs similar to those that run smartphones and laptops make more sense, and provide longer and stronger charges. A lithium battery can last up to 40 miles before recharging, and can achieve 20 miles per hour.

Whether an electrically powered bicycle is factory-ready, or the goal is to convert an older model to electricity, choosing the right lithium battery can be a challenge. There have been highly publicized reports of fires, and shipping regulations have become far more stringent. They are considered generally safe for use as a bicycle power source, and for most people the primary concerns are power and longevity.

Not all lithium power packs are the same. Prospective buyers should understand the role amperage plays, and why it is important to avoid unlabeled generic products that save money but are less reliable. Currently, China is the center of production, and the latest offerings can usually be recharged up to one thousand times, and have varying ranges based on amp hours and voltage.

Although riding is an undeniably greener way to get around, it is not without environmental concerns when batteries are involved. Lithium technology avoids the use of heavy metals common in other designs, but must be recharged, which requires a power plug that is often connected to a fossil-fuel generating plant. Those recharged using solar or wind energy exceed the efficiency of standard bicycles.

Like most developing technologies, early adoption is not for everyone, but those who do take part are supporting alternate forms of transportation that can make a real difference in the amount of pollution released by fossil-powered engines. The initial investment makes the most sense in locales where daily bicycle use is already a practical option.
