Grin Statorade Hub Motor Cooling Fluid
The Grin Technologies Statorade cooling fluid is designed to improve heat management in hub motors. Approximately 5 mL of ferrofluid is injected to facilitate heat transfer from the stator to the motor shell, reducing overheating and enabling higher continuous power without noticeable drag. Users may experience up to a substantial increase in sustained power capability when used as directed. The fluid requires only a small quantity and is designed to minimize any impact on motor drag.
- 5–8 mL fluid recommended for best results
- Enhances heat flow from stator to shell
- Can increase continuous power without overheating

Buying Guide
Key considerations when choosing a hub motor or conversion kit include intended riding style, wheel size, and frame compatibility. For urban commuting, a lighter, high-efficiency kit with pedal-assist support can extend range and reduce fatigue. Off-road or snow use benefits from higher torque and robust construction, such as 1000W–1500W motors and durable housings. Front hub motors offer easier installation on smaller bikes, while rear hub motors deliver better traction on inclines and uneven surfaces. Also assess the dropout width, axle diameter, and compatibility with disc brakes. Finally, consider the availability of a display, cruise control, and integration with your existing controller for a cohesive setup.
- Power and torque: 1000W vs 1500W; higher torque improves hill climbing
- Front vs rear hub: weight distribution, traction, and braking compatibility
- Compatibility: wheel size, dropout width, axle type, and disc brake compatibility
- Control and display: built-in LCD vs external controllers; visibility at night
- Durability and weather resistance: materials, seals, and corrosion resistance
- Installation and maintenance: wheel truing, bearings, and regular checks
