electric bicycle kit 48v 1000w motor
electric bicycle kit with 1000w brushless motor and offer light-weight, brushless, planetary-geared hub motors that are reliable, quiet, efficient, high-torque and affordable. 1000w motor must match 48v 20AH lithium battery for electric bike to work. Features: Motors use internal planetary-gearing to provide torque rivaling 1000W gearless motors. Hall-effect throttle includes power-on indicator. No-drag freewheeling and better torque combine for more efficiency and longer range. Additional options include choice of front or rear hub motor, controller power and voltage, battery type and size, wheel size, and flat-tire protection. This hub wheel is built in-house to desired sizes of 26″, and 700c by electric bike. The wheel build features high quality spokes and max loading is 200kg. For added protection from flat tires, you can request thorn resistant tubes or Kevlar tires.

electric bike spoke motor 48v 1000w brushless quick hub motor for rear wheel electric bike,the rear axle size is 165mm,suitable v brake and disc brake，brushless motors offer several advantages over brushed DC motors, including high torque to weight ratio, more torque per watt, increased reliability, reduced noise, longer lifetime, elimination of ionizing sparks from the commutator, and overall reduction of electromagnetic interference . With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor’s internals can be entirely enclosed and protected from dirt or other foreign matter.
