An electric bike having an improved effect of heat dissipation has a body, a driving device, and a battery. The body has a frame, a rear wheel, and a front wheel, wherein the rear wheel and the front wheel are mounted to the frame. The driving device is mounted to the body and has a motor and a shell. The motor is connected with the frame and has a front end near the front wheel and a rear end near the rear wheel. The shell covers the motor and has multiple inlets and multiple outlets disposed therethrough. The multiple inlets are located near the front end of the motor. The multiple outlets are located near the rear end of the motor. The battery is electrically connected to the motor. The front wheel, the battery, the motor, and the rear wheel are serially aligned.

A brushless motor stator includes a stator core and a stator winding. The stator core has a stator frame, a coil carrier and multiple pole shoes. The coil carrier is mounted on one of the two openings of the stator frame and has a tooth base and multiple teeth. The teeth are formed on a top surface of the tooth base. The pole shoes are formed on the inner annular surface of the stator frame. The stator winding is formed by using a single wire to wind around the tooth base, the multiple teeth and the multiple pole shoes, and passing through three of the multiple slots of the coil carrier to extend beyond the outer annular surface of the stator frame to form three extended segments to correspond to U-phase, V-phase and W-phase output terminals of a motor, thereby reducing the number of spot-welding on a wiring board.

A cord lock of the window blinds or shade includes a box having a chamber therein, an engaging block on an outer side, a first opening for a cord exiting the box, a second opening for the cord entering the box, a fixed locking portion on the outer side, and a flexible locking portion opposite the fixed locking portion; and a movable driving wheel, which is received in the chamber of the box, to be moved between a lock position, in which the movable driving wheel is moved toward the engaging block to clip the cord therebetween, and a release position, in which the movable driving wheel is moved away from the engaging block to release the cord. The fixed locking portion provides the box fixing to the top rail with a strong strength, and the flexible locking portion provides an easy way to mount the box on the top rail.

A blind fixing holder includes a first convex wall and a second convex wall facing each other for assembling a roller thereon. The first and the second convex wall are respectively and symmetrically bored with a vertical slide groove and a horizontal slide groove communicating with each other. The vertical slide groove has its upper end formed with an opening and its lower end formed with a contracted neck. Thus, the opposite ends of the roller can be fitted in the horizontal slide grooves and shifted therein through the openings and the contracted necks of the two opposite vertical slide grooves. The roller can be shifted leftward or rightward in the horizontal slide groove for the pull cord at either side of the blind to be wound and supported thereon.
