Expert’s Advice, Tips, & Guides For Buyers To Buying The Best E-Bikes
Everyone has more or fewer things that have been difficult to use. After buying, they have the consequences of not being willing to lose them and having to adapt to them.
So in addition to considering the cost of buying things, you also have to consider the usage status after buying.
Everyone who has been to the mainland should know that most of the electric cars that run on the road are electric cars.
Recently, in order to assemble electric bicycles, after checking the information, I found that most of the components are also made by the mainland.
In contrast, the electric vehicle environment in Taiwan is not yet mature. The current mainstream market can be roughly divided into two types of commodities, electric vehicles, and electric bicycles.
Among them, car dealers use electric vehicles as the main marketing force because of their profit.
In other words, never buy an electric locomotive!
Just because of a very simple situation: what if the half-way car runs out of electricity?
Everyone should have some experience with a broken locomotive or a trolley without oil, as long as the nearest locomotive is repaired, and it takes only a few minutes to refuel.
However, if the electric locomotive is broken or has no electricity, if it is broken, it can only be pushed to a few original factories for repair.
How Electric Bicycles Are Different Than Other Mountain Bikes:
Therefore, under the premise that the hardware environment such as battery exchange, charging station, etc. is not mature, he does not think of it except buying electric bicycles.
After determining the direction of buying an electric bike, what kind of car do you want?
The first one is to buy a brand car with a bicycle dealer. A brand car has a characteristic, that is, how expensive is it?
Lithium-ion batteries of the same specifications have been asked to be sold from 12k to 14k for brand cars, and only 5k to 6k for online purchases.
But the premise is that it will be installed, especially since the shape of the battery box of each brand car is different. It is indeed not that ordinary people can install it by reading the instructions.
Of course, brand cars are expensive, and as long as the car has problems, you can find a car dealer to continue to exploit and help deal with it.
The other is the assembly car. Since it is an assembly car, of course, you have to come by yourself.
But there are many kinds of parts for assembly cars to choose which to install?
Mainly have to consider the motor, battery, and others.
Key Points Of The Motor:
Let me talk about the key points of the motor first. Although the more horsepower the motor climbs, the faster the speed.
But for the same driving distance, a motor with more horsepower will consume more energy,
In addition, the higher the voltage the motor eats, the more power it will save, but it also increases the risk of battery failure.
Based on the specifications of currently available motors, it is recommended to buy
With 36V 350 or 360W motor, the single-tail road speed can reach about 30 kilometers.
The 48V 500W motor has a tail speed of about 40km. Some people who often need to double load or climb a gentle slope can consider it.
It is worth mentioning that the average person can easily ride about + 100W power.
In fact, the motor is also good, just pick the best-selling motor.
If you install the motor yourself, it is better to install it on the front wheel, if you ask the car dealer to install the motor, it is less likely to slip on the rear wheel.
The most important issue is actually the battery. In order to lower the cost of car purchases in order to increase the car purchase willingness of the general public,
Usually, the cheapest lead-acid battery is used. The new lead-acid battery may really be able to ride 20-30km,
However, under the premise that electric vehicles need high power output, 50% is left in less than a month, and the battery is completely broken in three months.
Actually, I checked the discharge curve of the battery on Yuasa’s website.
The smaller the capacity of the battery, the less energy can be taken out. Therefore, the longer the battery, the longer the life of the battery.
In addition, lead-acid batteries are also divided into power batteries and Shen cycle batteries. Power batteries are used for instantaneous large currents.
But electric vehicles need to continue to have large currents, so it is enough to buy deep cycle battery life.
Coupled with the problem of considering the weight of lead-acid batteries is too heavy, the conclusion is to buy deep cycle batteries under the limit of the load capacity,
I bought this awesome, the three batteries of 36v add up to about 20kg,
The support column placed on the rear seat of a general vehicle will be crushed, and the rear seat for cargo will be depressed.
However, these three deep cycle batteries are indeed durable, and it took only one year to break one.
One year later, the endurance is also 10km, and the final outcome is stolen by the thief.
Although very reluctant, in order to make the battery lighter, I can only bear to spend a lot of money to buy lithium batteries.
There are several types of lithium batteries, lithium poly, lithium fierce, lithium ternary and lithium iron,
Among them, lithium ternary and lithium iron have their own users,
Simply put, the energy density of lithium ternary is the highest, and the energy density of lithium iron is only about half of that of lithium ternary.
But lithium ternary can only withstand 50 degrees Celsius, and there are doubts about explosion and burning,
Lithium iron phosphate can withstand 70 degrees Celsius, and it will not naturally explode if it does not explode.
In the use environment where electric bicycles have a poor shock absorption effect, in general, car manufacturers use lithium iron phosphate batteries.
Supplement: If the parking place is separated from the charging place, the battery should be easy to disassemble and carry. Considering the load, it is recommended to choose a battery under 5kg.
Among them, the 36v10ah lithium-ion battery is about 4kg, the endurance is about 30km, the charging frequency is about 2000 times, and the service life is more than 2 years.
Others are mainly more convenient and considerations to replace locomotives,
First of all, with a total load of less than 120kg, it is recommended to buy a 20-inch folding bike, because a 20-inch bicycle is easier to be pulled into the elevator, and the folding bike can be used as a luggage to take the train or bus.
If it is greater than 150kg, it is recommended to buy a 26-inch mountain bike
In addition, If you consider double loading, you can empty the back seat, and then install a short rocket launcher and a think cushion to make the back seat more comfortable.
Install a locked batter box on the child seat or the front frame of the car to put the battery.
The bicycle lights on the market are not bright enough, buy a bright flashlight to install; buy a speaker that eats electricity, you have to change the battery, and it is more convenient to buy a bell.
At present, the cheap direction lights with mercury batteries are not practical to buy.
A flat tire is the biggest problem with cycling. Buy a toolset and put it on the car, At least you can decide if you want to do it your self.
After changing the sixth electric bike, I am correcting some of the things I wrote before.
- The most important suggestion is that the battery is limited to the outside of the battery pack, and how many pieces are installed so that there is no pressure to keep charging when there is no power.
- Generally commuting in the urban area, in addition to the bells, other equipment can be saved, because, in fact, it is not needed at all, it is better to ask the car shop to repair it if it is broken
