The Model 2 tricycle is designed for heavier loads and more aggressive riding, and has a more serious aesthetic than the original Haley Model 1. The Model 2 has an increased load capacity of 400 pounds.

Structural differences of the Model 2 include heavier dropouts, thicker front forks, a slightly taller stance, a slightly wider wheelbase in the same width tricycle, and a tougher pivot. The floor platform is stronger and extended forward as a bumper.

The wheels and pivot are pulled forward for a much different balance of the cargo space than a Model 1. The result is better handling of very heavy loads. The trike has a more even weight distribution over all three wheels, keeping the trike's tail and the rider firmly on the pavement, even when the cargo's weight is three times that of the rider. Other design differences keep the Model 2's turning radius from being increased in response.

The cargo box is stained and finished. The black-bound compound curves run deep down the front of the trike, giving the box panels more strength along its edges, as well as aesthetically balancing the non-centered front wheels.

Front wheels are double wall alloy mechanical disc brakes, bolted on for city life. A matching double wall disc rim is laced with a Shimano Inter-8 internal geared, coaster brake rear hub. High pressure black tires with liners are included.

The Model 2 tail's double downtubes make it stiffer, meaning even more transfer of pedal to forward movement traded for a little comfort. Other mechanical differences include double front parking brakes, standard black plastic fenders, and a solid brass bell.
