ELECTRIC BIKE

Electric BicyclesWhy build an electric bike?You may wonder why you are building your own electric bike if you can go buy an e-bike rack or need a bike to your local Wal-Mart or Canadian Tire for a reasonable price. The main reason is that these bikes suck. They are low-power small motors, controllers, low power and battery strength. That's fine if you just want to cruise slowly 30kph (18 mph) on a flat road, much to the local store and back and donâ € ™ spirit to pedal, but I see donâ € ™ t as the replacement of a car . We see them as crazy ride on a small hill to get, pushing or sometimes because the battery is empty. Traffic behind them rises on narrow streets, because they can move very slowly and no cars pass you.There are several companies producing high quality bikes make a very good performance, but only if they are willing to spend up to U.S. $ 10 000 and most of them still are not as fast as possible to build a bike for a fraction of the cost . If you are serious about replacing you need to build your car and the umbilical cord with oil companies on the same machine, then hand-pick high-quality components and parts to modify to improve performance and reliability. This way you can build a bike that is perfectly suited to your needs, and will last for many years.You may be thinking, why not build an electric bike instead of using the bicycle as a platform. Well, the bike has several advantages. In most places that do not receive a license or electric bicycle, which can save you thousands of dollars per year only. You can also ride an electric bike on bike paths and roads. In a motorcycle, you are obliged to obey the same rules as a car, so you're stuck in traffic jam waiting with all the other vehicles. The bike weighs less than a motorcycle chassis, they require less energy to move it means. This leads to more efficient vehicles that use a battery (and therefore cheaper) can be smaller for the same distance. The final advantage is that the bicycle in a bicycle instead of parking in a location that you save even more money by buying a can not be disabled parking permit.


Three important things to know, - Electric Bike BatteriesIf you want to build an electric bike is obviously that you need a battery. Many people are confused when they started buying batteries, because it received so many different types and different specifications for each brand of battery. I hope I can help clarify some of the secrets to make the decision easier for you.The first thing to consider is, the voltage of the battery you need. The bicycle speed depends directly on the battery voltage, the higher the voltage, the faster the bike. If you have a single engine to help you, as your bike is still likely that you only need one package 36 to 48 Volts to drive. On the other hand, if you want to use the bike more like a motorcycle and cruise around at high speed without contact with something in the category 72 to 100 volts with a much better performance. In addition, make sure the motor and controller for the voltage of the battery that you are suitable.The next thing is to consider the capacity of the battery, which is how long it last on a single charge. Measured by the number of ampere-hours (Ah), the download before it is empty, maybe. If a battery can power amplifier continually lose one hours long, has a capacity of 1 Ah. The ability of a larger battery of physical size Oh, if you compare the same chemical. 10Ah battery to be twice as large as a stack of 5Ah of the same type and location, his bike twice as far, if the amount to get the same speed. Several batteries can be connected in parallel (positive terminals all connected together and all negative terminals are connected together) for the Ah capacity or the desired level.The last thing to note is the 'C' classification or rate of discharge of the battery. The "C" rating of a battery is a number that represents further discharge of insurance (in amps) of the cell. Can make a battery rated at 1C its current capacity Oh, no damage. A battery can be evaluated 2C Oh shut down two times the amps. If a 10Ah battery at 1C discharge rated speed is 10 amps maximum security, the 10Ah battery, it shall be classified as 3C, you can download free 30 amps. Similarly, if the battery is 10 Ah estimated at 0.5 C made only 5 amps safely. Hope this helps clarify some of the mysteries about what you look for when buying batteries for your electric bike.

Batteries Electric Bike - Why you should not fully dischargeIf you want to buy or build your own e-bike, then there are some things you need to know in order to maximize the life of your loved one. Department of Defense or the depth of discharge is one of those things.In calculating the amount of battery capacity, you should plan for your trip away from your bike to a package download 80 percent of the Department of Defense. Most specifications of the life cycle of the battery (how often can you for a fee) are based on 80% of depth. If you need more than that every time you load the life span can be reduced. The batteries also lose capacity over time, with the additional option of 20% results in an additional buffer to replace it before. Do not forget accessories electrical charges, which are powered by a battery, such as light and add a warm jacket if you plan to use. Another thing to consider, the battery capacity is reduced when the temperature is cooler. You will need to perform about 15% decrease in capacity, at temperatures near or below freezing, then you may need to pack a greater capacity when cold weather travel plan. In an average daily commute is preferable to run only 70 to 75 percent of your battery to be used with all accessories, if they have a capacity of one bit, if you decide to make a detour and a few races on the way home. If you use at nearly 100 percent of the battery in order to get to your destination you will always have too much power to accelerate or to fight against the wind, that could leave you with a dead battery worries. Itâ € ™ s why you need a buffer full of energy, so you can travel without stress. If you try to push the boundaries of the battery is completely removed when the drainage is about to go to work and do not give the entire life cycle of the same. It is interesting to try the battery with care.To avoid battery leakage can add or buy a battery that has a low consumption or low-voltage cutoff. A cable connects the battery to the motor controller and the voltage of the battery cell falls below a predetermined voltage is triggered the LVC and the controller to stop the power supply to the motorcycle. When increasing the voltage of the power is back and move the bike back. A CVL is a device for greater safety and certainty not accidentally during battery discharge.

Batteries Electric Bike - What is a kilowatt-hour Why do I know?If you want to buy or build your own e-bike, then you have to learn a little about the various technical terms, so that you can make an informed decision when buying batteries for your bike.A term that may arise is the watt or white, for short. The watt-hours is an important measure to determine how much battery capacity you have to traverse a certain distance.Represents the total available energy in the battery to die. It is calculated by multiplying the ampere-hours or Ah of a battery voltage of the pack. A package of 36 volt 20Ah and 10Ah pack contains two 72-volt 720 watt-hours, so that both should be able to achieve the same long distance if traveling at the same rate. With the 72V package that can accelerate quickly and grab a higher top speed than the 36V. If you do this (which is very hard to not use all the extra power) and how to run faster than the wind resistance you will find more uses more energy. This is the distance traveled before the battery ends up less than the lead pack of 36 V at a slower pace, but you get used to your destination faster.With the motor shaft in a Crystalyte 24-inch wheel and a motor controller to 90 amps, which is about 35 to 45 watt hours per mile average (58 watt hours per mile). This is a cruising speed of about 65KPH (40 mph) without pedaling. What is the speed, acceleration and top speed will affect the energy consumption. It will also depend on how flat or hilly terrain is and how much weight you carry. You can use less than 25 watt-hours per km if you drive too slowly (with the same parameters as above) on the ground or the use of 65 watt-hours per flight KM rate of climb.
