The ASI BAC855 P&P is a sinusoidal field-oriented control (FOC) motor controller built for the Inokim OX Super electric scooter with the 60 V 21 Ah battery. It arrives pre-configured and pre-wired. As a result, no soldering and no wiring modifications are required. Every connector matches the original harness one to one.
Installation is straightforward. You open the underside of the deck, remove the stock controller and drop the ASI BAC855 into its place. Because the plugs line up, the owner can complete the swap without special equipment. No workshop tooling and no harness splicing are involved.
Compatibility is specific. This controller fits the Inokim OX Super with the 21 Ah battery only. Owners of the Inokim OX Eco and Inokim OX Hero must first upgrade to a newer, more powerful battery pack. Before ordering, state which battery you run. The controller is then programmed to match that pack.
Key Benefits
- Plug and play preparation – connectors match the factory harness, so soldering is never needed.
- Top speed up to 77 km/h – this figure was recorded during testing with a 67 kg rider.
- Launch from 0 km/h – the scooter pulls away without a kick start from the rider.
- Sinusoidal FOC control – the ASI BAC855 drives the motor smoothly across the entire rpm range.
- 106 A current in every configuration – output power is then selected according to your battery.
- Up to 6000 W on a 72 V pack – more than double the 2650 W of the stock 21 Ah setup.
- Programmed before dispatch – settings are written to match the battery you specify.
- Motor cooling add-ons – fins or an aluminium heatsink can be ordered alongside the controller.
Who Is This Controller For?
This upgrade targets Inokim OX Super owners who want more power and more speed from the scooter. With the original 60 V 21 Ah battery, the controller works immediately. Furthermore, no additional parts or modifications are needed for that configuration.
The Inokim OX Eco and Inokim OX Hero cannot run this controller in stock form. Both models first need a new, stronger battery capable of delivering higher current. Once that pack is fitted, the upgrade becomes possible on those scooters too.
Riders on custom-built packs are covered as well. A 60 V custom battery rated at 110 A yields 5500 W. A 72 V custom battery rated at 110 A yields 6000 W. One point deserves attention before you order. After installation, the original brake sensors are no longer used.

Motor Cooling Accessories
Motor cooling parts can be added to your order. The plastic fins push air in the opposite direction as the motor spins, which cools the hub. They are moulded in plastic and finished in black.
The aluminium heatsink works differently. It enlarges the heat-dissipating surface on the motor and moves air as it rotates. Consequently, the motor is cooled by two mechanisms at once. The heatsink comes in orange or black. Select the NONE option if you do not want cooling accessories.
Why Choose the ASI BAC855 P&P
The main difference is the preparation. This controller ships with programmed settings and matching plugs. Therefore, you skip the soldering iron, the harness rework and the guesswork around parameter tuning.
Field-oriented control also changes how the scooter feels. Instead of the abrupt delivery of simpler square-wave units, the ASI BAC855 modulates torque smoothly. Rollout from a standstill becomes possible, and power stays consistent across the rev range.
Finally, the configuration is matched to your hardware. The same 106 A current limit applies to all three variants, yet the resulting output tracks your pack voltage. That is how a stock 2650 W scooter moves up to 5500 W or 6000 W.
Frequently Asked Questions
Does this controller fit the Inokim OX Super?
- Yes, it is built for the Inokim OX Super with the 60 V 21 Ah battery.
- All connectors match the factory wiring on that model.
Will it work on an Inokim OX Eco or Inokim OX Hero?
- Not in stock form. Both models require a stronger battery first.
- The new pack must deliver higher current before the swap.
How fast will my scooter go?
- Up to 77 km/h was measured in testing with a 67 kg rider.
- Rider weight and battery choice influence the result.
Do I need to solder anything?
- No. The harness is prepared and the plugs match the originals.
- You open the deck, remove the old unit and fit the new one.
How much power can I expect?
- 2650 W with the stock 60 V 21 Ah pack at 106 A.
- 5500 W with a 60 V custom 110 A pack.
- 6000 W with a 72 V custom 110 A pack.
What happens to the brake sensors?
- The original brake sensors are no longer used after installation.
Do I need to tell you which battery I use?
- Yes. The controller is programmed to your specified pack before dispatch.
Should I add motor cooling?
- Plastic fins in black move air across the spinning motor.
- The aluminium heatsink adds surface area and airflow together.
- Choose NONE if no cooling accessory is wanted.
The ASI BAC855 P&P turns the Inokim OX Super into a noticeably quicker machine while keeping the installation within reach of the owner. Specify your battery when ordering, pick your cooling option, and the controller arrives ready to bolt in.
