An articulated bracket that clamps a pendulously-hanging friction-wheel onto the frame of a pushbike to convert it into an Ebike. The axial driveshaft of the pendulous friction-wheel is gripped in the chuck of a cordless drill and the pendulum's swing geometry is configured with respect to the one of the pushbike's tires to cause the friction-wheel to be forced against the tire when the drill is activated, thereby propelling the pushbike forward. A torque-arm mounted on the pendulum prevents counter-rotation of the drill's housing. To enable the rider to control power to the driven wheel, a handlebar-mounted cable mechanism actuates the drill's trigger. In a preferred embodiment, the friction-wheel includes an internal ratchet mechanism that allows friction-free pedalling of the pushbike while the drill's trigger is released.
