Technical details & package contents

What makes the TM50 Pro motor unique?

• Thick motor windings for super low resistance: get the most out of your motor without overheating.
• Developed for SurRon Ultra Bee, with mounting options for other vehicles.
• Encoder motor: for finer control and smoother operation, even at low speed!
• Developed and designed in the EU: high-quality materials for increased longevity
• Compatible with the TC1000 controller

Important: TM50 Pro motors are compatible with the stock Ultra Bee battery, but we highly recommend using 80V nominal 22S batteries (92.4V fully charged) to achieve optimal performance.

*Our products have an IP67 rating, achieved by testing in distilled water under laboratory conditions. Please note that this rating does not imply suitability for continuous underwater use as it may result in damage. Additionally, the connectors on the product are not waterproof and must be kept dry to ensure proper functionality and safety. The warranty does not cover malfunction or damage arising from the use of the products in activities where frequent or extended submersion in water is expected, such as riding in streams, rivers, or flooded areas. Over time, seals and components may degrade, reducing the water-resistant effectiveness of the product. Damage resulting from this natural wear and tear is not covered by the 2-year warranty.

Modifying a stock electric vehicle can result in the vehicle becoming non-compliant with your local road safety regulations. It’s essential to consult with experts or authorities before modifying your vehicle to ensure adherence to road legality.
