Many cycling enthusiasts always consider upgrading their bicycles to e-bikes when they lack physical strength, but they hesitate whether it is necessary.
Firstly, they feel that the modification process is hard. Secondly, they are afraid that riding with the motor running out of power after modification will still be laborious.
But in fact, such concerns stem from a lack of understanding of electric power assist systems. The following will tell some things about detachable electric bike motor that you may want to know.
Definition of detachable electric bike motor
For electric bicycles, the function of the motor is directly responsible for mechanical transmission, acting on the force applying part of the vehicle’s pedaling and the frequency of pedaling, completing the conversion of electrical energy into kinetic energy, and is the ultimate tool for providing auxiliary power.
Detachable electric bike motor is an important component of the electric bike conversion kit, providing powerful power support for bicycles. Detachable electric motors are relatively rare in light electric bikes such as electric bicycles and scooters, but with the development of technology, detachable electric bike motor is also used in some bicycles to assist in modifying bicycles and provide power support for riding.
The advantage of detachable electric bike motor
The sense of security provided by electric assistance is incomparable to that of human powered bicycles.
Long e-bike range endurance: Not only can it take riders to farther places, but it can also bring people back without worrying about physical issues on the return journey. Some electric assisted bicycles have a range of up to 100 miles or more, but typically around 50 miles, depending on the size of the battery.
Powerful electric assistance: When climbing, riders no longer have to overcome fear and hesitation, but bravely ride on electric assistance to maintain speed and move forward without worrying about the difficulty of steep slopes.
Easy to repair and maintain: The detachable design makes the repair, maintenance, and replacement of the motor easier.
Portability: In some portable electric vehicles such as folding electric bicycles, the detachable electric motor helps to reduce weight, and it’s convenient for users to carry.
Safety issue: Users can remove the motor while parking to reduce the risk of electric vehicle theft.
How to detach and install the motor?
At present, the motor of electric bicycle is mainly fixedly installed at the center of the wheel, the middle of the bicycle frame, or the rear wheel of the bicycle. Therefore, modifying bicycles often requires changing tires, installing batteries, and connecting wires.
But the detachable electric bike motor is very convenient. Taking the installation of a certain brand’s detachable electric bicycle motor as an example, its product only needs to be fixed on the front fork or the lower part of the front fork of the bicycle, and can be transformed into an electric assisted bicycle, which is used in almost all types of bicycles.
The cons of detachable electric bike motor
At present, there is still a lot of room for development in the technology of detachable electric bicycle motors, and their actual use will definitely be affected by the size and weight of the bicycle.
And currently, the price of detachable electric bicycle motors is not cheap. A certain brand’s detachable motor commuter version for bicycles costs $499, and the exploration version costs $599. Considering the same price or even lower, a brand new electric bike cost less.
FAQs
If you really love cycling, but have average physical strength, not much riding experience, and have a bicycle at home, upgrading it to an electric assisted bicycle is really a good choice. It can effectively compensate for the shortcomings in performance, be more inclusive, and allow you to go further and see more scenery with the same force.
But detachable electric bike motor is not a good choice for upgrading. Maybe when its techonology is mature, installing one in your bike would be good.
The laws and regulations of electric bicycles vary in different countries and regions, but there are similarities in motor power and maximum driving speed.
According to the regulations on electric bicycles in China, adding or modifying electric bicycle batteries or generators is considered illegal modification. And the Chinese national standard states that the rated continuous output power of electric bicycle motors should be less than or equal to 400W. When driving with electric drive, the maximum design speed should not exceed 25km/h. When driving with electric assistance, if the speed exceeds 25km/h, the electric motor shall not provide power output.
The regulations for electric bicycles in the United States stipulate that EPAC electric assisted bicycles require a power not exceeding 750W and a speed not exceeding 32km/h (20mph) when ridden by a person weighing 77kg (170 pounds).
Taking Chinese and American laws and regulations as examples, it can be seen that installing a detachable electric bike motor is illegal. Before cycling, please make sure to check the rules and guidelines in your area to ensure safety and comply with the law.
Conclusion
In recent years, despite the constantly changing modes of transportation, bicycles are still loved and widely used due to their numerous advantages of convenience, flexibility, and low cost.
Electric assistance provides auxiliary power to bicycles through a e-bike drive system. The detachable electric bike motor is still in the development stage. If you want to modify traditional bicycles, you still need to purchase a mature and high-quality bicycle electric assistance kit.
