Kunteng Dual Drive E-Bike Controller 36V 48V, 17A Max for Two Hub Motors

Two hub motors, one controller, and a front or rear lead that goes wherever you plug it

The controller is a slim silver aluminum housing with a label that reads Controller for brushless motor. The label lists the model KT36/48ZWSR2D-ffF09, a rated voltage of DC36V/48V, a rated current of 8A, a maximum current of 17A with a 1A tolerance, a speed set of 1 to 4.2 V, a low level brake input and low voltage protection at DC30/40 V with a 0.5 V tolerance.

As a dual drive unit it carries two motor cables, so one controller can run a front hub motor and a rear hub motor together. The maker's diagram shows the two motor cables can be linked to either motor, whether it sits in the front or the rear wheel. The maker presents it as the Kunteng 17A controller for lithium battery e-bike conversions, mountain bikes included.

Key Benefits

• Dual drive, two motor cables Two round motor connectors let one controller serve a front and a rear hub motor.
• 36V and 48V rated The label lists DC36V/48V, so the same controller covers both battery voltages.
• 8A rated, 17A maximum Rated current is 8A and the maximum current is 17A with a 1A tolerance.
• Six connection groups Motor, display, power, PAS, throttle and brake each have their own plug.
• Low level brake input The brake plugs use a low level input for the cut off signal.
• Silver aluminum housing A ribbed aluminum case with end screws holds the electronics and carries the label.

Best for: Riders converting a mountain bike or another bicycle to electric with two brushless hub motors and a lithium battery.

Why It Works

A single controller for two motors keeps the wiring of a two wheel drive build in one place. Either motor cable goes to either hub, so you do not have to work out in advance which lead belongs to the front wheel and which to the rear.

How It Fits Your Routine

Fix the controller on the frame near the battery, as the maker's diagram shows, and run the two motor leads toward the front and the rear wheel.

Plug each motor lead into a hub motor, front or rear, in whichever order suits your cable routing.

Connect the display, the pedal assist sensor, the throttle, the brake levers and the power leads to their matching plugs, and choose a battery that matches the 36V or 48V rating.

FAQ

What does dual drive mean? The controller has two motor cables, one for a front hub motor and one for a rear hub motor, so a single unit runs both wheels.

Which voltage does it use? The label lists a rated voltage of DC36V/48V.

What are the current ratings? The rated current is 8A and the maximum current is 17A with a 1A tolerance.

Which parts plug into it? The motors, a display, the power leads, a pedal assist sensor, a throttle and the brake levers each have their own plug.

What is in the box? One dual drive controller. Hub motors, battery, display and sensors are sold separately.
