 TCab Tech’s E20 Sets the Pace for Advanced Air Mobility

TCab Tech, founded in Shanghai in 2021 by Yon Wui Ng and a team of aerospace engineers, has quickly established itself as a leader in China’s advanced air mobility sector. The company’s mission, reflected in its name “Time Taxi,” is to provide zero-emission, time-saving aerial transportation for urban environments. TCab Tech’s flagship project, the E20 eVTOL aircraft, is at the heart of its recent industry prominence and investment surge.

The E20 represents a significant leap in eVTOL design and production for China. This five-seat aircraft, accommodating one pilot and four passengers, features a tilt-rotor architecture that combines the vertical lift capabilities of helicopters with the cruise efficiency of fixed-wing aircraft. With a cruise speed of 260 km/h (162 mph), a maximum speed of 320 km/h (199 mph), and a range of 200 km (125 miles), the E20 is engineered for rapid, point-to-point regional and urban transport.

It uses six electric motors powered by four tilt propellers for vertical and forward flight, plus two double-stacked rotors dedicated to vertical takeoff and landing. The aircraft’s carbon fiber composite fuselage, panoramic wraparound windows, and high seagull wing enhance passenger safety and comfort and provide operational efficiency and spectacular city views.

Safety and reliability are core to the E20’s design. The aircraft uses distributed electric propulsion (DEP), ensuring that the failure of one or more motors or propellers does not compromise flight safety. Critical systems are redundant, and in the unlikely event of a complete propeller failure, the E20 can glide safely to a landing. The 800V ultra-fast charging system enables rapid turnaround, supporting high-frequency operations in busy urban corridors.

TCab Tech’s recent commercialization efforts have accelerated the E20’s path to market. In March 2025, the company secured a $34.73 million Series B-II funding round, raising total capital to about $100 million. This investment is fueling the industrialization of the E20, with a focus on scaling production and developing vertiport infrastructure across Shanghai and the Yangtze River Delta. The funds also support the ongoing type certification process with the Civil Aviation Administration of China (CAAC), which is expected to be completed by late 2026. Strategic partnerships with investors further strengthen TCab Tech’s influence in shaping low-altitude airspace regulations and expanding regional air routes.

A major milestone in April 2025 cemented TCab Tech’s commercial viability: BOC Leasing, a subsidiary of Bank of China, placed an order for 100 E20 aircraft, marking the largest single eVTOL procurement by a financial institution in China. This partnership provides the capital and financial expertise needed to ramp up production and opens avenues for innovative leasing models tailored to urban air taxi operators and emergency medical services. The collaboration is expected to facilitate the E20’s entry into domestic and international markets, including the Middle East, through TCab’s partnership with UAE-based Autocraft.

With its advanced tilt-rotor technology, robust safety features, and strong financial backing, TCab Tech is poised to play a pivotal role in the future of urban air mobility. The E20’s development and production are setting new standards for efficiency, safety, and sustainability in the eVTOL sector, positioning the company at the forefront of China’s and the world’s next-generation transportation solutions.

Future Roadmap

China’s regulatory and infrastructure environment uniquely supports advanced air mobility, setting the stage for rapid eVTOL adoption and commercialization. Over the past several years, the Chinese government has prioritized developing the low-altitude economy, integrating it into top-level policy and economic planning. The Civil Aviation Administration of China (CAAC) has introduced a flexible regulatory framework for low-altitude airspace, streamlining flight approvals and reducing bureaucratic barriers that have slowed progress in other countries. This regulatory clarity is reinforced by ongoing legislative updates, such as the proposed revisions to the Civil Aviation Law in 2025, which aim to ensure rational airspace allocation and robust safety standards for both operators and infrastructure.

On the infrastructure front, China is investing heavily in vertiports and supporting facilities. As of early 2025, more than 388 new vertiport programs have been launched in just five months, with cities like Shenzhen planning over 1,200 take-off and landing platforms for air taxis and drones by 2026. Local governments are not only funding vertiport construction. Still, they are also opening up hundreds of new low-altitude air routes, as in Hangzhou and Anhui, to facilitate urban and regional aerial mobility. This coordinated, top-down approach, combining central policy direction with empowered local execution, has created a fertile environment for companies like TCab Tech to scale production, accelerate certification, and rapidly deploy their aircraft across China’s most populous and economically dynamic regions.

TCab Tech has articulated an ambitious vision for the E20 platform extending well beyond its initial five-seat configuration. The company plans to develop a comprehensive product line that includes 6-seater, 8-seater, 10-seater, and ultimately 20-seater variants to address diverse commercial applications.

The certification process continues to advance, with the company completing the certification basis (G1 Issue Paper) with CAAC in December 2024. Following anticipated certification in late 2026, TCab Tech plans to launch trial routes in Shanghai and other cities in the Pearl River and Yangtze River Deltas, with widespread air taxi operations expected by 2035.

With over 200 pre-orders secured and strategic partnerships, including collaboration with Autocraft for UAE operations, TCab Tech is well-positioned to capitalize on the growing demand for sustainable urban air mobility solutions.
