Electric Bike Pedal Assist Sensor for Duotts C29
This replacement PAS component is presented for the Duotts C29 e-bike conversion kit. The compact black assembly includes a ring-shaped sensing part, an attached cable, and an orange three-pin connector. It is shown at the crank and bottom-bracket area of an electric bicycle, where a pedal-assist component is part of the bike’s electrical arrangement. The product is a sensor assembly, not a complete conversion kit, controller, battery, motor, or display.
Its circular sensor form, cable lead, and orange plug give the part a clear identity among electric bike spare parts. The product materials associate this PAS replacement with the Duotts C29 application. For a parts listing or maintenance project, the assembly can be identified by its crank-area format and visible connector style rather than by general bicycle-accessory descriptions.
Product Details
A pedal-assist sensor is a compact component used in a pedal-assist arrangement. This version is shown with a black circular inner opening, a cable extending from the sensor body, and a three-pin plug at the end of the lead. The ring-shaped portion is illustrated at the crank-side position, while the cable routes away from the assembly toward its connection point.

The supplied title identifies this item as a PAS replacement bike part for a Duotts C29 e-bike conversion kit. The product focus remains on the individual sensor component. Its visible construction separates it from other electrical e-bike parts: the circular sensor body is paired with a cable and a three-pin connector in one compact assembly.
Key Features of the PAS Sensor Assembly
-
PAS component format: Identified as a pedal-assist sensor for an e-bike conversion-kit application.
-
Crank-area configuration: Product images show the assembly at the bicycle crank and bottom-bracket area.
-
Three-pin connector: A visible orange plug and cable lead are included in the illustrated sensor assembly.
-
Ring-shaped sensing section: The black circular body and inner opening are visible in the product details.
-
Duotts C29 application: The supplied product title presents the item for the Duotts C29 e-bike conversion kit.
These details belong to the same sensor assembly. The ring-shaped section provides the recognizable crank-area form, and the cable terminates at the three-pin plug shown in the images. Together, they make the component easier to distinguish from other nearby e-bike parts with different housings, cable layouts, or connections.

Dimensions and Visible Construction
The product images mark the main body at approximately 5.3 cm by 4.5 cm, with a cable marking of 7.7 cm. These markings describe the illustrated PAS sensor assembly. Its compact dimensions suit the grouped layout shown around the crank area, where the ring-shaped part and cable are located close together. The orange three-pin connection is visible as part of the same component.

The table gathers the visible and source-identified details in one place. The dimensions describe the illustrated part, while the connector appears on the attached cable. The product’s crank-area form, plug style, and named Duotts C29 application are the defining details for this PAS replacement component.
Replacement and E-Bike Parts Applications
The item is presented for use in a Duotts C29 e-bike conversion-kit context. It can be listed as an ebike pedal sensor replacement for that named application and as a component in an electric bike spare parts range. The materials show the part with the bicycle drivetrain area, so it is naturally associated with the crank-side portion of an e-bike arrangement.
For workshops, parts stores, and individual e-bike repair projects, the sensor assembly has a focused identity. Its identifiable details are the circular sensor section, cable, and orange plug. This makes it a specific PAS part rather than a general-purpose bicycle accessory, particularly where the requested replacement is a crank-area sensor assembly with the visible connector format.

Installation-Oriented Product Information
The sensor is shown in a crank-mounted and bottom-bracket-oriented position. Its circular opening is the visible feature associated with that location, and the cable extends from the sensor body to the three-pin plug. During component installation, keep the assembly and cable route orderly so the ring-shaped part can remain positioned as shown in the product materials.
The product is described as a Duotts C29 PAS replacement part. A 3 pin ebike pedal sensor configuration is visible in the images, together with the crank-area sensor form and image-marked size. The cable can be routed without twisting or pinching around the compact assembly, keeping the sensor area clear and organized.
Why This PAS Replacement Part Is Easy to Identify
Several visible details distinguish this product from a generic cable or plug: the black ring-shaped section, the integrated lead, the orange three-pin connector, and the crank-area application image. Together, these elements describe one coherent PAS sensor assembly. The compact body marking of approximately 5.3 cm by 4.5 cm provides another direct visual reference for the part shown on this page.
The product is also listed among electric bike spare parts, placing it in a service and replacement category rather than among complete bicycles. It can be presented with related e-bike components while retaining its distinct pedal-assist identity. The source-named Duotts C29 application gives the product a defined e-bike conversion-kit context.
