Replacing or upgrading the controller on an ebike or scooter means matching voltage and power rating to your motor. The controller manages speed, braking, and sometimes extra features like cruise control or pedal assist. The four options below cover a wide price range, from a 350W controller to a 2000W conversion kit.
Quick take: If you are repairing a light scooter, the 36V 48V 350W DC Speed Controller is a basic entry point. If you want a controller that supports both 500W and 600W motors, the 36V-48V brushless controller includes E-ABS braking and regenerative braking. If you are planning a full conversion, the 48V 2000W kit bundles a motor, controller, and LCD throttle.

Product Notes
36V 48V 350W DC Speed Controller Electric Bicycle E-bike Scooter Brushless Motor
This controller works with 36V or 48V systems and is rated at 350W with an 18A current rating. It is made from aluminum alloy and is designed for electric bicycles and scooters. Because its power rating is 350W, it is best suited for lighter commuter scooters or smaller ebike conversions rather than high-wattage builds. It also comes as a bare controller, so you will need to match it with the correct wiring and throttle setup for your existing bike. If your motor is already 350W or you are replacing a failed controller, this is a straightforward option.
36V 350W Electric Bicycle E-bike Scooter Brushless Motor Speed Controller DC
This silver controller is rated for 36V and 350W, with a 28V undervoltage cutoff. It is designed for electric mini bikes and mountain bikes, and it uses a 120-degree phase angle for brushless motors. It does not have a reverse connection cable, so you will need to handle reversing another way if your build requires it. It also carries a 90-day manufacturer warranty. This controller makes sense if you have a 36V 350W mini bike or mountain bike and want a direct replacement with a silver housing.
Electric Brushless Motor Kit 48V 2000W DC For E-bike Scooter Bicycle Conversion
This is the full conversion kit in the group. It pairs a 48V 2000W brushless motor with a 48V 2000W 45A 18-MOSFET controller, plus an LCD throttle with battery display and power lock key. The kit is specified for electric scooters, ebikes, and go-carts. The battery is not included, so you will need to supply one separately. It also includes a three-speed selector, reverse, indicator light, electric brake, hall sensor, power lock, and brake light functions. If you are starting from a bare frame or upgrading an existing motor, this all-in-one setup covers the motor, controller, and throttle.
36V-48V Brushless Controller For E-bike Electric Bicycle 500W/600W BLDC Motor US
This controller works on both 36V and 48V systems and is rated for 500W or 600W BLDC motors, with a limit current of 30A and a low-voltage cutoff at 30V/40V. It includes E-ABS braking, regenerative braking, reverse, cruise control, pedal assist sensor, and three-speed modes. Because it supports dual-mode sensor and sensorless operation, it can work with a range of ebike or tricycle motors. The main thing to watch is matching the low-voltage cutoff with your battery pack; the controller expects a 36V or 48V pack. This makes it a versatile option for mid-power builds.
Final Recommendation by Use Case
Light scooter or simple repair: the 36V 48V 350W DC Speed Controller at USD 13.59 is the least expensive option in this group and works with 36V or 48V systems.
36V mini bike or mountain bike: the 36V 350W controller at USD 15.28 adds a silver housing and a 90-day manufacturer warranty, but it does not have a reverse connection cable.
500W/600W ebike: the 36V-48V brushless controller at USD 26.29 brings E-ABS braking, regenerative braking, cruise control, and pedal assist.
Full conversion: the Electric Brushless Motor Kit 48V 2000W at USD 199.07 bundles the motor, controller, and LCD throttle; you supply the battery.
