In today’s market, electric bicycles and motorbikes have emerged rapidly due to the increasing frequency of use by users.
These types of vehicles have the great advantage of running smoothly, economically (as they do not require fossil fuels) and quietly. Therefore, many users, especially urban users, prefer it because of the less daily usage required.
To differentiate between bicycles and electric motorbikes, they can be classified based on the battery used, specifically based on two criteria: either the construction material or the ability to disassemble/install.
FirstlyAccording to the criteria of classification by manufacturing material, there are mainly 4 different types of electric vehicle batteries. At the bottom, lead acid batteries are the most “rudimentary” batteries and were the first to be used. This type of battery is very cheap to make, but toxic (due to lead), heavy, low energy density, short life cycle, and takes a long time to charge.
NiMH (Nickel Metal Hybrid) and NiCad (Nickel-Cadmium) batteries are located in 2 positions on lead acid batteries. These two types of batteries still retain most of the disadvantages of lead-acid batteries but have slightly improved energy density, life cycle and charging time. These 3 types of batteries are mainly used on older bicycles/electric motorbikes and have gradually disappeared, with lead acid batteries considered “extinct”.

LastThe most popular battery type on electric bicycles/motorbikes today is lithium-ion. Lightness, good energy density and stable operation give lithium-ion an absolute advantage over older electric vehicle batteries. However, the manufacturing cost of this battery is not cheap as lithium is not a common material.
Another way to differentiate electric vehicle batteries is whether they are fixed or removable. Fixed batteries are the more popular choice due to their simplicity in both engineering and design. For this reason, prices for electric bicycles/motorbikes that use stationary batteries are often more accessible.
On the flip side, cars that use removable batteries are often heavier and bulkier. This is because removable batteries require a separate mounting and fixing mechanism. This factor forces the vehicle body structure to be calculated very carefully and may also affect the vehicle design to ensure technical parameters.
Currently, not many large car manufacturers have successfully developed a range of electric motorbikes/bikes that can dominate the majority of the market share, instead many start-ups are still able to enter this new market – Photo: Dance
Additionally, safety must also be considered as removable batteries require the battery to be located in an easily accessible location, and therefore may be affected by external forces. This issue is quite significant on electric bicycles as the battery is usually located outside, whereas electric motorbike batteries are usually located safely under the saddle.
However, this type of battery has one big advantage: users do not need to worry too much about the operating range. With only 2 batteries operating and charging alternately, users can use the car continuously without waiting for the car to recharge for several hours every day.
