Electric bicycles as a means of transportation, with the development of society and the awakening of environmental awareness, gradually go into a variety of fields. In the daily commute, it is even more convenient than a car, however, the lack of understanding of it is likely to cause some accidental injuries, so it is important to have an accurate understanding of the purpose and role of each component before setting out. Only with the right understanding can you make better use of it on your ride.



The battery is one of the most important parts on an electric bike, and its relatively high cost makes it one of the most expensive accessories on an electric bike. As the name implies, the electric bike's power comes entirely from the battery, as it is the life of the electric bike. Most of the electric bicycle batteries on the market today are lithium batteries, which have a better specific capacity than NiMH batteries. For the same capacity of lead-acid batteries, the weight of a lithium-ion battery is equivalent to a laptop, which is very light and portable. Its service life can also do much better than other kinds of batteries.



Electric car controller is the core control device used to control the start, run, in and out, speed, stop of electric car motor and other electronic devices of electric car, it is like the brain of electric car, it is an important part on electric car. The current controllers used on electric bikes, such as beecool bikes, use super quiet design technology and unique current control algorithm and constant current control technology, which makes it applicable to any brushless electric bike motor and has considerable control effect, which improves the universal adaptability of electric bike controller and also makes the electric bike controller blocking current and dynamic running current completely consistent, which ensures The battery life, and improve the starting torque of the electric vehicle motor.



Main characteristics of electric vehicle motor Brushless DC(direct current) motor is widely used in electric vehicles because it has two advantages compared with traditional brushed DC motor. First, long life, maintenance-free and high reliability. Secondly, high efficiency and energy saving . In brush DC motors, the brushes and commutator wear out faster due to the high motor speed, and in addition, its noise is relatively large. Therefore the advantages of brushless DC motors are obvious.



Electric bike shock absorbers are one of the main criteria to consider for riding comfort. Most e-bikes are equipped with fork/front shock absorbers, but generally only the mid to high end are equipped with dual shock absorbers. They are mainly used to suppress the shock and impact from the road when the spring absorbs the shock and bounces back. When passing over uneven roads, although the shock absorbing spring can filter the vibration from the road, the spring itself will have a reciprocating motion, and the shock absorbers are used to suppress this spring jump and make it smooth. If the shock absorber is too soft, the body will jump up and down, and if the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly.



Electric bicycles, like bicycles, commonly have V brakes and disc brakes, and disc brakes are far more expensive than V brakes. V brakes are very powerful, because they rely on friction rim braking, so the rim must be adjusted in place, and it is not easy to deform, but it has a fatal flaw, it is easy to hold when braking and produce side slip, which is very dangerous. Disc brakes can avoid this. Among disc brakes, hydraulic disc brakes are the best, because the braking force generated by oil is much greater than that of ordinary disc brakes with hand pinch force. For the relatively heavy, inertial electric bicycle, the safest and most secure brakes must be hydraulic disc brakes.


-Shift system

The role of a bicycle shifting system is to change the speed of the bike by changing the chain and the different front and rear sizes of the gear discs. When you use the electric throttle, it really doesn't do anything special. But when you want to use the pedal, it can do some magic. The size of the front disc and the size of the rear disc determine how hard the bike spins the pedals. The larger the front disc and the smaller the rear disc, the more effort you will feel when pedaling. The smaller the front disc and the larger the rear disc, the easier the pedaling will be. In general, the former is chosen when the road is flat and in good condition, and the latter is chosen when it is hard to climb. Depending on the rider's ability, you can adjust the speed of the bike by adjusting the size of the front and rear disks, or respond to different roads and conditions.



The crankset is a collective part of flywheels in different sizes, chainrings and chain on either ebikes or normal MTBs. Flywheel is a wheel-shaped accumulator with large rotational inertia installed on the machine's rotary shaft. When the machine speed increases, the kinetic energy of the flywheel increases, storing up the energy, when the machine speed decreases, the kinetic energy of the flywheel decreases, releasing the energy. The flywheel can be used to reduce the speed fluctuation of the mechanical operation process. A quality crankset will make the ride smooth and easy, and there will be no chain jams or dropped chains as well.



The bicycle saddle is in direct contact with the ass when riding bicycle accessories, long-distance riding we certainly hope their ass can be comfortable, but the soft cushion can not hold the body steadily affect the pedaling efficiency, the ass is like trapped in the sofa, soft saddle and ass contact area is large, the pedal fast ass has been moving instead because of excessive friction and pain, the hard cushion is more suitable for fast pedaling action. Base staff, the choice of the cushion as far as possible when choosing a wide and soft comfort seat cushion.
