A coupler pin (often referred to as a clevis pin or cotter pin depending on the context) is a mechanical fastener used to connect two components in a way that allows for movement or rotation. It is commonly used in various machines, vehicles, and other mechanical systems, including e-rickshaws. The coupler pin plays a critical role in holding parts together while allowing them to function effectively in applications that require movement.

The back shocker (rear suspension) of an e-rickshaw is an essential component designed to provide a smoother ride and improve vehicle stability, especially on uneven or rough roads.

Viscosity Grade: Commonly, AW 68 grade oil is used, offering optimal damping and lubrication properties.​MSMEmart

Volume Options: Available in various sizes, including 175ml, 300ml, and 400ml, catering to different maintenance needs.​

Formulation: Both synthetic and mineral-based oils are available. Synthetic oils typically provide better performance in extreme conditions.​

Additives: High-quality shocker oils contain anti-wear and anti-corrosion additives to prolong the life of suspension components.​

BEST QUALITY RIM FOR E RICKSHAW 
 WEIGHT 3KG
E-Rickshaw Wheel Rim refers to the structural component of the wheel assembly designed specifically for electric rickshaws (E-rickshaws). The rim supports the tire, ensures load distribution, and facilitates smooth and efficient vehicle movement. E-rickshaw rims are engineered to handle the unique requirements of electric three-wheelers, such as heavy passenger loads, frequent stops, and urban or semi-urban driving conditions.

​E-rickshaw wiring is a critical aspect of ensuring the vehicle's optimal performance, safety, and reliability. A well-designed wiring system connects various components such as the battery, motor, controller, lights, and indicators, facilitating seamless operation.

The brake spring is an important component in a vehicle’s braking system, especially in drum brakes and mechanical brake setups.
It is a strong, flexible spring designed to keep the brake shoes or pads in their correct position and to help them retract after braking.

The E-rickshaw rear axle bush is a crucial component that ensures smooth operation and stability of the vehicle's rear axle assembly. It serves as a cushioning element, absorbing shocks and reducing wear between metal parts.
