Styling & A-Surface Design
From category research and ergonomic fit to proportions and surface language — production-ready concepts and Class-A surfaces.
- Concept sketches
- Renders
- Clay models
- A-Surface
Shenzhen · Since 2011
From one sketch to a production line. Styling, structural engineering, CMF and production validation — delivered by one team, cutting the back-and-forth between design and manufacturing.
01 Capability
A rideable is a product where structure, ergonomics and cost constrain one another. We build structure and manufacturability into the design from the first sketch — no concepts that only look good in renders.
From category research and ergonomic fit to proportions and surface language — production-ready concepts and Class-A surfaces.
Frame load analysis, folding mechanisms, tolerance stacks and assembly logic — tooling-ready 3D data and 2D drawings.
Materials, finishes, palettes and decal systems — production-ready colorways, not just a mood board.
Prototype builds, trial assembly, mold reviews and first-article checks — we stay on site long after design handoff.
02 Case Studies

03 Process
Every stage has defined deliverables and sign-off points. You see tangible output at every step — not three weeks of silence and a vague “still working on it.”
01
Category positioning, target users, cost band and competitor teardown — boundaries defined first.
Product definition brief02
Three to five directions explored in parallel; the direction call is made at sketch stage, never deferred to modeling.
Sketches + renders03
Class-A surfacing, structural design, load verification and assembly logic advance in parallel.
3D data + 2D drawings04
Prototype builds, trial assembly, road testing and issue closure — revisions locked before sign-off.
Prototype + issue log05
Mold reviews, first-article confirmation and line follow-up — until the first container ships.
Production confirmation04 Studio
Fifteen years at this, one obsession: good design must be buildable — otherwise it’s just a picture.
TANQI DESIGN (Shenzhen Tanqi Structure Technology Co., Ltd.) is a Shenzhen industrial design studio focused solely on rideables. Stylists and structural engineers work as one mixed team from day one — so styling is never overturned by structure after the fact.
Our clients include vehicle brands, ODM factories and export teams — 100+ companies served, among them XDS (Shenzhen), Fuji-ta (Tianjin) and Feishen Vehicle. We take on new programs from scratch as well as model refreshes, structural cost-downs and overseas compliance adaptation; prototyping and supply chain, handled end to end.
