SPIDER Automation MY1016 24V 250W Brushed DC Motor | 11-Tooth #25 Chain Drive | Electric Bicycle Applications
Product Overview & Motor Construction
The SPIDER Automation MY1016 24V 250W Brushed DC Motor is designed for electric bicycle conversion systems and other compatible chain-driven electric mobility applications. It combines a brushed DC motor with an integrated 11-tooth #25 chain sprocket, providing a direct mechanical interface for chain-based power transmission.
The motor features a four-bolt base mounting bracket with M6 threaded mounting points for installation into a suitable frame or motor support. Its 12.2mm shaft diameter, 2650RPM rated speed and 25cm cable provide important mechanical and electrical reference details for drivetrain integration and controller selection.
Technical Features & Functional Characteristics
- Brushed DC Motor Configuration: Uses a brushed motor design suitable for operation with a compatible brushed DC motor controller.
- Integrated Chain Sprocket: The 11-tooth sprocket provides a mechanical drive interface for a compatible #25 chain.
- Four-Bolt Base Mounting: Features four M6 threaded mounting points for securing the motor to an appropriately designed support structure.
- Defined Shaft Diameter: The specified 12.2mm shaft diameter provides a reference for mechanical fitment and assembly checks.
- Rated Rotational Speed: The specified rated speed is 2650RPM for drivetrain and transmission matching.
- Rated Torque: The listed rated torque is 100N-cm, equivalent to 1N·m.
- Reversible Rotation: Supports clockwise or counterclockwise rotation through supply polarity reversal, subject to the connected controller arrangement.
- Electrical Cable: Supplied with a 25cm cable for connection to a suitable motor controller.
Electrical Configuration & Speed Control
The MY1016 motor is specified for a 24V DC supply with an operating power rating of 250W. The listed rated current is 9–11A, while the no-load current is specified as ≤2.2A. These values describe different operating conditions and should be considered separately when designing the electrical system.
For speed regulation, use a compatible 24V brushed DC motor controller. The controller should be selected according to the motor’s current requirements, startup demand and intended mechanical load. A brushless motor controller is not suitable for this brushed DC motor.
Chain Drive & Mounting Configuration
The integrated 11-tooth #25 sprocket is designed for use with a matching #25 chain. The chain and driven sprocket must be compatible with this standard. The final driven-wheel speed and torque depend on the selected transmission ratio and operating conditions.
The four-bolt base bracket features M6 threaded mounting points. The specified 12.2mm shaft diameter should also be checked when designing the mechanical interface. Confirm the mounting-hole spacing, available clearance, fastener engagement and chain alignment before installation.
Applications
This 24V brushed DC motor is suitable for compatible chain-driven electric propulsion systems and mechanical drive applications requiring a compact motor with an integrated sprocket.
- Electric Bicycle Conversion: For compatible bicycle conversion systems using a 24V brushed motor and chain transmission.
- Electric Scooters: For suitable scooter drive configurations designed around the motor’s mounting and chain interface.
- Motorised Bicycle Systems: For custom motor-assisted bicycle drive arrangements.
- Electric Trikes: For compatible three-wheel electric vehicle propulsion systems.
- Compact Electric Vehicles: For appropriately engineered small electric mobility platforms.
- Chain-Driven Utility Platforms: For compatible utility vehicle systems requiring a 24V geared or chain-transmitted motor drive.
- Mechanical Drive Assemblies: For mechanisms requiring a brushed DC motor with an integrated #25 chain sprocket.
- Engineering Development: For development and testing of electric motor, controller and chain transmission assemblies.

Installation & Operating Recommendations
Before integrating the MY1016 motor into an electric bicycle or other mechanical drive system, verify the mounting interface, chain compatibility and electrical requirements. The controller, battery and chain transmission should be selected according to the motor’s actual operating conditions and the intended mechanical load.
- Controller Selection: Use a 24V brushed DC motor controller with suitable continuous and peak current capability for the motor’s 9–11A listed rated current and startup demand.
- Battery Matching: Select a compatible 24V DC battery system capable of supplying the required operating and startup current.
- Chain Compatibility: Use a compatible #25 chain and matching driven sprocket. Do not substitute another chain standard without verifying pitch and sprocket compatibility.
- Mounting Fasteners: Use suitable M6 fasteners with appropriate thread engagement and verify the mounting arrangement before applying mechanical load.
- Mechanical Alignment: Check the chain line, sprocket alignment and shaft interface to reduce unnecessary mechanical stress and chain wear.
- Direction Control: Reverse motor polarity only through a suitable switching or controller arrangement designed to support forward and reverse operation.
- Initial Testing: Test the motor at controlled speed and verify chain tracking, mounting security and controller response before normal vehicle operation.
