The Spoke Wheels ecosystem comprises a defined set of upstream, midstream, and downstream actors that collectively transform raw inputs into finished wheel assemblies for bicycles, motorcycles, and low‑speed vehicles. Upstream, alloy and carbon‑fiber producers supply billets and yarns that are processed by component manufacturers. Midstream, original equipment manufacturers (OEMs) integrate spokes, hubs, and rims into complete wheels, often leveraging specialized coating and testing technologies. Downstream, distributors, retailers, and end‑users complete the value capture through sales, installation, and after‑market services. The ecosystem boundary also includes regulatory agencies that certify load‑rating compliance and financing entities that underwrite bulk procurement for fleet operators.
