The Harley-Davidson sub-brand Livewire has announced a new electrical platform called “Arrow” as part of Livewire’s IPO. In this case, the battery frame is fully load-bearing, so it also takes over the chassis function of the main frame. At the front, the steering head bearing is screwed onto a subframe, the motor is integrated into the housing at the rear / below.

The swing arm bearing leads Livewire coaxially to the motor bearing, which makes length compensation of the final drive by means of a belt tensioner superfluous. The input reduction gear is also omitted, instead the reduction of the belt final drive is increased. The aluminum shell of the carrying battery should also have enough surface for pure air cooling thanks to cooling fins. All of these aspects should save weight and costs, the two key issues of large electric motorcycles.

The electric arrow uses thedrive unit as the frame, saving weight and complexity.

In order to keep the platform flexible, Harley wants to use water cooling (as in the Livewire One / Harley-Davidson Livewire) or even refrigerant to control the temperature of the built-in round cells, in addition to passive air cooling. This means that even thermally demanding concepts are possible. Depending on the equipment, Harley wants to offer battery pack nominal voltages of 50 to 400 volts.

End Goal 50,000 Units by 2025

The first model based on Arrow (project name “S2”) is said to be below the Livewire One in terms of price and other parameters. When and how this motorcycle will come, Livewire did not communicate. What the company communicated, however, is a desire to sell a total of 50,000 electric motorcycles by 2025. In view of the devastating Livewire / One sales to date, that means in the real world: A motorcycle must come out well in advance that people will actually buy in significant numbers.
