steel gear electrical bicycle motor

1. Fork size:135mm 2. Well tidy outgoing wire 3. N.W.:3.05KGS

1. Voltage:24-48V

2. Load current: hot:0.8-1.2A; cold:1.2-1.4A

3. Rated Power:180W-500W

4. Efficiency: more than 80%

5. Rated speed: 20-30km(16-26inch)

6. Gear: All the gears made of carbon steel with high strength reliability to avoid the gear deformation, the phenomenon of the broken teeth and shave their heads.

7.An increase of riding fun with big starting torque and fast starting. Lubricant used in auto gearbox. An oil board equippen is used to make the gear lubrication, more effective, more reliable and better cooling performance of the motor.

8. Working temperature:-25°C-45°C, suitable for use in the cold place.

9.Using a one-way clutch bearing structure with the maximum torque up to 200N.M, that is 4 times the motor torque. No magnet resistance effect after power off. Its feature is longer mileage, high reliability and less power used.

10. Less drivingcurrent, a single motor can load 90kg, 25kl/h, the current 5.5-5.6A. longer battery life; By using our patented coaxial structure, our company solved the noise problem completely which cause by precision high-speed motor in the past.

11. Motor structure is our company's patented structure with better concentricity, more efficient and less power. It uses torque transmission with sliding structure and reduce the noise caused by vibration.

12.Motor with double sealed and six waterproof structure, so it can be waterproof under water 10cm and no load operated 160 hours. The insulation resistance infinite, so that's why it can no-load opereated 160 hours under water.

13. Impacet resistance, direct start of 20N.M with frequency 2 times per minutes. No failure after hundreds of thousands of times using.

14. Load vibration test: a single wheel can load 90KG,current 6A and can run 6 hours a day and no failure after running 38,000 km in 1500 hours.

15. The efficicency of platform width: for example a 36V, 20 inch motor, the efficiency is 74%-84% and torque 4.5-22N.M

16. 12A current in 3500 hours continuous operation, motor trouble-fee.
