The Wheezy is a compact and easy-to-use electric trailer option for people looking to add a bit of electric assist to their pedaling.
This contraption is available in the form of a highly compact unit that includes a single wheel with a 9 x 3.5-inch all-terrain tubeless tire, a detachable battery pack, brushless electric hub motor, microcontroller, a built-in charger with a cable and a draw bar. It is designed to come with both pedal sensor as well as thumb throttle options. The pedal sensors prompts the microcontroller to initiate the motor when you start pedaling, while the thumb throttle allows you to control motor power directly.
The advantage of using the Wheezy has to do with the ease of attaching the simple hardware, letting you concentrate on using it rather than installing it.
