Inokim OX / OXO Motor Heat Sink – Solid Metal Cooling Radiator

The Inokim OX motor heat sink is a passive metal cooling radiator built for the Inokim OX and Inokim OXO electric scooters. It mounts directly onto the hub motor and enlarges the surface area that releases heat. The part is machined from strong metal and ships as one solid piece.

This cooling radiator works without any moving parts. There is no pump, no fan and no hoses involved. Heat travels from the motor casing into the radiator body, and the airflow generated while riding carries that heat away. As a result, the system needs no wiring, no coolant and no maintenance routine.

Riders usually fit this heat sink after installing a more powerful controller. Higher current raises the temperature of the motor windings, which increases the risk of overheating. The radiator helps lower motor temperature during both normal commuting and demanding riding sessions.

Key Benefits

• Lower motor temperature – the larger metal surface transfers heat into the surrounding air more quickly.
• Strong metal construction – resists vibration and road impacts encountered during daily riding.
• One-piece design – there are no joints or fasteners between sections that could work loose over time.
• Built for upgraded controllers – a practical answer after modifying the scooter electronics.
• Fully passive cooling – no coolant, no pump and no electrical supply are required.
• Model-specific fitment – shaped for the motor geometry of the Inokim OX and OXO.
• Reduced overheating risk – cooler running protects the windings and the magnets inside the motor.
• No change to scooter handling – it attaches to the motor and needs no extra electronics.

Who Is This Heat Sink For?

This radiator is made for the Inokim OX and Inokim OXO electric scooters. The Inokim OX is the single-motor model, while the Inokim OXO is the dual-motor version. Both scooters use a hub motor, and this cooler mounts onto that motor.

It is most useful for riders who have already installed a more powerful controller. In addition, it suits people covering longer distances or climbing hills frequently. During those rides the motor runs under higher load for extended periods.

Because the Inokim OXO carries two motors, the radiator is sold as a part for one motor. Therefore, cooling both motors requires two units.

Technical Specifications

Why Choose This Cooling Radiator?

This cooler is shaped for a specific motor type rather than sold as a universal accessory. Consequently, it sits against the side of the Inokim OX and OXO motor without adapter plates or shims.

The solid metal body also sets it apart from multi-part coolers. In those designs, heat has to cross several joined sections before it reaches the air. Here, heat moves through a single mass of metal, so the transfer stays direct.

Furthermore, this is one of the few ways to manage motor temperature after a controller power upgrade. Such an electronic modification raises the current, yet the motor itself remains unchanged. The radiator addresses exactly that thermal problem.

Frequently Asked Questions

Which scooters does this motor cooling radiator fit?

• It fits Inokim OX electric scooters.
• It fits Inokim OXO electric scooters.
• It mounts onto the hub motor.

Does this radiator work with the dual-motor Inokim OXO?

• Yes, the design suits the Inokim OXO motor.
• The set contains one solid radiator.
• Cooling two motors requires two units.

When is it worth fitting this heat sink?

• When a more powerful controller is used on the scooter.
• Higher current raises the winding temperature.
• The larger surface area helps release that heat.

Does the radiator need coolant or a pump?

• No, cooling is entirely passive.
• There is no pump, fan or hose.
• Airflow during riding does the work.

How many radiators do I need for my scooter?

• The Inokim OX has one motor and needs one unit.
• The Inokim OXO has two motors and needs two units.
• Each set includes a single radiator.

Does fitting it change how the scooter rides?

• No, it attaches to the motor only.
• No additional electronics are required.
• Scooter controls stay exactly the same.

What is the radiator made from?

• Strong metal in a one-piece form.
• The construction resists vibration and road impacts.
• There are no joints between separate sections.

Will it help on long rides and hill climbs?

• Yes, those rides keep the motor under sustained load.
• The extra surface area speeds up heat release.
• Lower temperature protects windings and magnets.

For riders who have upgraded the controller on an Inokim OX or OXO, motor heat becomes the limiting factor. This one-piece metal radiator adds cooling surface exactly where the heat is produced, without coolant, wiring or moving parts.
