Pukka Electric MiniBike
From Wikipedia, the free encyclopedia
The Pukka Electric Mini-bike is a small, battery-powered, two-wheeled electric vehicle. It is capable of carrying a single passenger, weighing a maximum of 220-225 pounds (100 kg - 102 kg), to speeds up to 16 MPH (26 km/h).

[edit] Components
The Pukka is powered by two 12-volt sealed lead-acid batteries contained in a rear compartment, held by the frame behind the seat. It has an electronic motor control board which uses Pulse-width modulation (PWM), and can provide up to 55 amps when required[1]. It receives low voltage signals from the throttle, which is attached to the right handle bar. The braking system is a drum brake activated through a metal brake cable from a brake handle on the left handle bar. A circuit runs through the brake handle to allow the motor control board to detect when the brake is being used and shut off power to the motor. Thus, the Pukka is designed so that the motor and the brakes cannot be used at the same time.
[edit] Models
Currently, the Pukka has only one model, the GX400C, released in 2002, which has undergone many minor parts changes, including the throttle assembly, kickstand, and internal circuit board or PWM controller.
