Environmental Benefits of Electric Bicycles

Replacing a gas powered vehicle with an electric bicycle has many benefits to the environment. They release much less pollutants into the air from exhaust gases. Although they run on electricity that needs fuel to be generated, an average of 25 gallons of fuel is saved for every 500 miles an electric bicycle is used instead of a car.

Lead pollution from electric bicycles

Lead pollution is one of the largest environmental problems concerning electric bikes. The batteries from electric bikes are lead-acid batteries. Electric bike batteries last roughly 10,000 kilometers and thus must be frequently replaced. Research states that even if it were possible to recycle 100% of these batteries, 30% of the lead would be emitted into the environment.

Electric bikes more eco-friendly than regular bicylces

In a recent study, it has been suggested that the Yike Bike may be more energy efficient than a person peddling on a normal bicycle. The reason for this is due to that when a person peddles a normal bicycle they must consume more food for more energy. The energy required to produce that food is greater than the energy required to power the Yike Bike. However, the exercise required to ride a normal bike is always a good thing.

Energy cost and environmental concerns of different Batteries

The energy storage source of an electric bicycle is the rechargeable battery. At present, there are 4 battery chemistries that are observed in use.
The Lead Acid (PbA)
Nickel Cadmium (NiCad)
Nickel Metal-Hydride (NiMH)
Lithium Ion (Li-ion)
While the Lead Acid battery is most common, and Nickel Cadmium is less used, and the rest two have bright futures for manufacturing. The life-cycle energy use of each of the four batteries above will be examined individually in order to analyze the efficiency and the pollution possibilities. (The comprehensive data on the total energy required for the production of rechargeable batteries has been difficult to find. But there are tables of manufacturing process, and the table of the cost for the airfreight.)

Are E-Bikes that eco friendly?

Opponents charge that e-bikes are unsafe, increase congestion, and indirectly pollute the environment through increased power plant emissions and lead pollution from their heavy batteries. Several cities have attempted to, or successfully, banned electric bikes from roadways, including the mega-cities of Beijing and Guangzhou. Electric bikes use one car-sized lead acid battery per year. Each battery represents 30-40 percent of its lead content emitted to the environment in the production processes, resulting in about 3 kilograms of lead emitted per battery produced. When scaled up the 40 million electric bikes currently on the roads, this is an astonishing amount of lead emitted into the environment.

Electric Bicycles can be very Eco-Friendly

Electric bicycles can be very eco-friendly. However some people might not think so. A lot of advantages come with an electric bicycle. For example the Trek Ride+ electric bicycles allow you to either pedal the bicycle with no assistance of a motor or you can change the assistance level the motor gives you. Being able to choose the assistance level will allow you to get a workout while riding or quickly pedal to your destination. The Trek Ride+ models also have a feature called regenerative breaking. The regenerative breaking allows momentum from breaking to be converted into energy, which is then used to recharge the battery. This allows for increased range for each charge of the battery. Also the battery on the Trek Ride+ is a 33-cell battery, which allows for a faster rate of charge as well as a better life. According to Trek the battery will not start to degrade until around 600 charges of the battery. So by the time the battery wears out you will probably need a new bike anyways. The 33-cell battery also extends the range of the bicycle. On average you can ride up to 25 miles on a single charge. This allows most people to commute to work and back home without having to recharge the battery. Trek also offers the Ride+ system on various models. One of them being the Trek Transport+, this bicycle is meant for hauling large cargo. This is perfect for the person commuting to a farmers market or running errands.

Environmental Effects From Electric Bikes

According to [2]electric bikes being driven instead of cars significantly reduces carbon dioxide emissions. Apperntly bicycle trips result in 70 grams less carbon dioxide emissions. The Netherlands are testing this out and it is showing to be reducing their CO2 emissions by 110 to 280 kilotons. If more countries used electric bikes this could result in a drastic reduction in co2 emissions. Especially in densily populated cities where bikes would be heavily used. If bikes were used more, the air would be cleaner significantly helping the global warming issue. With electric bikes, driving range also increases which in turn would increase the use of electric bikes in general, even further reducing the environment impact.

Ride an E-bike, Save the Earth

The E-Bikes have a reduced harmful impact on the environment. The E-Bikes have no emissions. The emissions of CO2 into the environment is very harmful and is considered a link to climate change. the absence of emissions is beneficial to the environment. Also less raw material are needs to construct the E-Bikes. Less natural resources would depleted in the environment. Also less power, energy, and fossil fuels will be needed in the construction of the E-Bike. Overall, E-Bikes are very environmentally sound. http://alohaebike.com/
