Preliminary planning – Clarify the purpose and requirements

Consider the main application scenarios of electric bicycles, such as whether they are used for daily commuting, leisure cycling,or mountain off-roading, etc. Different uses have different performance requirements for vehicles. For instance, commuting may place more emphasis on range and comfort, while off-roading demands stronger power and good shock absorption.

Set a budget

The cost of customizing an electric bicycle varies depending on the selected accessories and functions. Determine the price range you can accept so that you have a basis when choosing components later. This includes core components such as the frame, motor, battery, and controller, as well as some optional accessories like headlights and shock absorbers.

Select the frame

Choose a frame of the appropriate size based on your personal height and cycling habits. The frame materials include aluminum alloy, carbon steel, etc. Aluminum alloy is relatively light and corrosion-resistant. Carbon steel has high strength but is relatively heavy. At the same time, consider the style of the frame, such as the simple style of city bikes or the sturdy style of mountain bikes.

Component selection – Motor

The motor is the core power component of an electric bicycle. Common types include hub motors and mid-mounted motors. Hub motors are easy to install and can be directly integrated into the wheels, with relatively low prices. Mid-mounted motors can better distribute power and enhance riding performance, but they are more expensive. Select the appropriate motor power based on the budget and the demand for power, which is generally between 250W and 2000W.

Battery

The choice of battery determines the endurance of an electric bicycle. The mainstream batteries include lead-acid batteries and lithium batteries. Lead-acid batteries are cheap, but they are large in size, heavy in weight and have a relatively short battery life. Lithium batteries have the advantages of small size, light weight and long battery life, but they are relatively expensive. Choose a battery of appropriate capacity based on the required riding distance. Common capacities range from 10Ah to 20Ah.

Controller

The controller is responsible for regulating the speed and power of the motor to ensure its stable operation. Select a controller that matches the motor, and pay attention to ensuring that its parameters such as voltage and current are compatible with both the motor and the battery. A high-quality controller can enhance the stability and comfort of riding.

Other accessories

Choose accessories such as shock absorption systems, braking systems, handlebars and seats according to your personal needs. For instance, if you often ride on rough roads, you can choose shock absorbers with better performance. Emphasis is placed on braking performance and it can be upgraded to a disc brake system.
