E.Jet 競速賽道機車

A track-racing motorcycle concept inspired by fighter-jet aerodynamics. Drawn as a post-graduation side project; in a 2021 hiring interview at ARMASPEED, the design lead pointed at this work and said: this is why we want to hire you.

A line that opened a door

In 2016, this was a post-graduation side project. A simple design exercise: take the intake ducts and bodywork of fighter aircraft, and translate them into the silhouette of a competitive sport motorcycle. There was no client. There was no production path. It was an aesthetic test.

Five years later, in a hiring interview at ARMASPEED, the lead designer paused on this page of the portfolio. He said the design itself mattered less than what it showed: that a designer could carry an aerodynamic vocabulary from one product category to another. Three weeks later, I was working on aero kits for sport cars.

A jet wearing two wheels

The cowl ducts read as twin intakes. The headlight is recessed behind a narrow slit, mimicking a cockpit canopy. The fuel tank tapers like a spine. Every line is borrowed from aviation. None from existing motorcycle design.

05 · Note on the 2026 Renew

Iterating in 2026

The 2016 renders were KeyShot output, flat and student-toned. For this page I picked the same model back up and iterated it with three current AI tools: Vizcom for surface and material studies, Gemini for cinematic scene rendering, and Kling AI for the concept reveal film below. The design intent is the same. The questions I am asking about it are not.

The point is to keep my hands on the current generation of AI design tools: pushing them, steering them, noticing where they help me see the form differently. Not delegation. Active collaboration.
