Eve Air Mobility has announced a key supplier selection, naming BETA Technologies as the provider of electric pusher motors for its conforming prototypes and production eVTOL aircraft. The agreement strengthens Eve’s supply chain as the company advances towards first flight of its Engineering Prototype, expected in late 2025 or early 2026.

With a backlog of 2,800 eVTOLs, Eve’s partnership with BETA represents a potential 10-year opportunity of up to USD 1 billion for the U.S.-based propulsion specialist. The selection follows an evaluation period during which Eve purchased, tested and validated BETA’s electric motor performance.

Johann Bordais, CEO of Eve Air Mobility, described the agreement as a pivotal milestone. “Their electric motor technology will play a critical role in powering our aircraft during cruise, supporting the maturity of our propulsion architecture as we progress toward entry into service,” he said. Bordais noted that Eve is committed to working with suppliers that meet rigorous safety standards and deliver proven engineering solutions.

BETA designs and manufactures proprietary electric propulsion systems featuring high power-to-weight ratios, energy-conversion efficiency and simplified architecture with fewer parts than traditional engines. “Our pusher motors have already proven high performance and reliability in thousands of demanding real-world operations across the globe,” said Kyle Clark, CEO and Founder of BETA Technologies. He added that the company’s manufacturing capability will support Eve at scale as electric aviation moves closer to commercial adoption.

The addition of BETA reinforces Eve’s strategy of partnering with leading aerospace suppliers as it develops its eVTOL aircraft. BAE Systems, Garmin, Honeywell Aerospace, Intergalactic and Nidec Aerospace are already part of Eve’s supplier base, covering batteries, avionics, external lighting, thermal management and lifter motors.

Eve’s aircraft features a lift-plus-cruise configuration using eight dedicated vertical-lift propellers and fixed wings for cruise. A dual electric pusher system provides propulsion redundancy, optimised performance and reduced operating costs while minimising noise. The company is currently conducting comprehensive testing to evaluate all aspects of the prototype’s operation, performance and safety features.
