Electric bicycle scooter controller, 790 Mignon Maimai 6-tube controller suitable for 24V 36V 48V systems with 250W to 350W rated power, ideal for brushless geared and high-speed motors up to 350W, dimensions 9cm x 5cm x 3cm
790 Mignon Maimai 6-Tube Controller for Electric Bicycles and Scooters

This 790 Mignon Maimai controller is a core component designed for electric bicycle and scooter propulsion systems. It functions as a direct replacement or upgrade unit, managing power delivery from the battery to the motor. With a rated power handling capability of 250 watts to 350 watts and a broad operating voltage range spanning 24 volts, 36 volts, and 48 volts, it offers significant flexibility for different vehicle setups. Its 6-tube construction indicates a robust design for switching and regulating the electrical current required by various motor types. The controller's compatibility extends across multiple common battery technologies, making it a practical choice for maintenance, repairs, or custom builds where specific voltage and power parameters are known.
Features and Construction

The controller is built around key electrical specifications that define its application. Its construction is centred on managing the power flow within the defined limits, with physical dimensions that allow for integration into typical e-bike frames or scooter decks.
Material and Build
The controller utilises standard electronic components arranged on a circuit board, housed within a casing. The mentioned 6-tube design refers to the power stage, likely using MOSFETs or transistors, which are crucial for efficiently switching high currents to the motor. This build is specified for the electrical demands of 250W to 350W motors, ensuring it can handle the associated thermal and electrical loads within its voltage range. The materials are chosen for their electrical properties, such as conductivity and heat dissipation, rather than for aesthetic purposes.
Size and Practical Fit
With external dimensions of 9 centimetres in length, 5 centimetres in width, and 3 centimetres in height, the controller presents a compact footprint. This size is practical for installation in the confined spaces often found on electric bicycles and scooters, where space around the bottom bracket or within the deck is limited. The modest proportions mean it can be mounted securely without requiring major modifications to the vehicle's frame, which is a key consideration for a direct replacement part.
Uses and Placement

This controller is intended for use in light electric vehicles, primarily those classified as electric bicycles or scooters. Its placement is within the vehicle's electrical system, connecting the battery pack and the motor, and it is typically mounted in a location protected from direct weather exposure and physical impacts.
Event or Professional Use
For professional repair workshops or individuals undertaking custom vehicle builds, this controller serves as a standardised component. Its specified compatibility with motors up to 350W and multiple voltage systems makes it a suitable stock item for servicing a range of customer vehicles. In scenarios like repairing a failed controller or upgrading a system within its power bracket, this unit provides a known quantity with clear electrical parameters, allowing for reliable system restoration.
Everyday Home Use
For the home mechanic or owner performing their own bicycle or scooter maintenance, this controller offers a defined replacement part. If the original controller in a 24V, 36V, or 48V system has failed, this unit can be installed provided the motor's power rating (up to 350W) and battery type are compatible. It enables the user to return their personal transport to working order by swapping out the faulty component with one that matches the original system's key specifications.
Benefits and Buying Value

The value of this controller lies in its defined specifications and broad compatibility, which provide clarity for purchasers matching it to an existing system. It addresses the need for a reliable power management unit without requiring custom engineering for many common e-bike setups.
Reuse and Low Maintenance
As a solid-state electronic device, the controller requires no routine maintenance. Its value in terms of reuse is inherent in its function: it enables the continued operation of the electric bicycle or scooter's drivetrain. By replacing a failed controller, the user preserves the value and utility of the larger vehicle system, including the motor, battery, and frame, avoiding the cost and waste of replacing the entire vehicle.
Why Choose This Product
This controller is chosen for its clear match to specific system requirements. The decision criteria are factual: does the user's system operate at 24V, 36V, or 48V? Is the motor rated at 350W or less? Is it a brushless geared or high-speed motor type? If the answers align with the controller's specifications, it represents a functionally appropriate component. It avoids the uncertainty of unspecified or generic controllers by providing exact voltage, power, and compatibility details necessary for a successful installation.
