Duoflex Bike Trailer & Double Stroller

Role: Lead Engineer | From concept sketch to production launch

As the lead engineer for this project, I was responsible for the full product development cycle — from early ideation through final production. I began by conducting extensive competitive benchmarking to understand the landscape of existing bike trailers, identifying gaps and opportunities for innovation. This research informed targeted brainstorming sessions, where I facilitated feature exploration and helped define core design criteria based on voice of the customer insights.

One of the most impactful outcomes of this early-phase work was the development of a patent-pending, sideways-folding frame — a first-of-its-kind solution that allows the trailer to collapse into a compact, easy-to-store footprint. This directly addressed a top customer pain point: limited garage space.

I led the mechanical design of all components and mechanisms, modeling the full product in SolidWorks and prototyping key features using 3D printing and other rapid validation tools. I collaborated with international manufacturing partners in China to initiate production, resolve design-for-manufacturing issues, and guide the team through several pilot builds. I also conducted root cause analysis on early failures, iterating designs to meet performance, safety, and cost targets.

In addition to engineering execution, I supported ASTM compliance testing across stroller, toy, and bike trailer safety standards to ensure regulatory readiness.
