High-Output 72V 5000W Brushless Motor
The doinal motor delivers 5000W nominal power with a peak around 10kW, operating at up to 6800 RPM (peak 8000). A pure copper core improves conductivity, enhancing efficiency to about 90%. This translates to more usable power, longer range, and energy savings for serious riders. The motor employs a V-Magnet rotor with five magnet pairs to smooth torque and boost density. It includes a KTY84-130 temperature sensor for real-time temperature monitoring when paired with compatible controllers, reducing overheating risk and extending lifespan. An integrated aluminum heatsink housing provides rapid cooling, while the IP54 rating offers protection against dust and water splashes. Front/back or bottom mounting options add installation flexibility.

Buying Guide: Key Considerations For Electric Bike Motors
Power and torque: Choose a motor with power and torque suited to your riding terrain. High-powered options (5000W+) are ideal for steep climbs and heavy riders, while mid-range motors (250–750W) suit urban commuting and flatter routes.
Motor type: Brushless DC motors (BLDC) are common for aftermarket upgrades due to efficiency and reliability. Dual-motor or mid-drive configurations provide balanced torque and better handling on varied terrains, especially with fat tires.
Cooling and protection: Motors with integrated heatsinks, robust insulation, and IP ratings (like IP54) perform better in adverse UK weather and long descents. Temperature monitoring sensors help prevent overheating during extended use.
Battery and range: Consider voltage, capacity (Ah), and chemistry. Higher voltage systems (36V–72V) enable more power delivery, while larger capacity batteries extend travel between charges. Real-world range varies with rider weight, terrain, and assist level.
Mounting and compatibility: Ensure mounting options match your frame and fork. Front/back or bottom mounting flexibility, as well as compatible controllers, will influence installation ease and performance tuning.
Safety and controls: Look for features such as regenerative braking, thermal protection, and programmable controllers. For kids’ bikes, safety features like auto-brake on throttle release and stable design are essential.
Maintenance and warranty: Access to spare parts, ease of service, and warranty terms impact long-term costs. Durable materials, corrosion resistance, and workshop support are valuable in the UK environment.
Budget and use case: High-power motors suit enthusiasts and hilly regions; lighter setups are better for daily commuting and novice riders. Compare total ownership costs, including batteries and replacement parts, to find the best value.
