Manufacturing feasibility assessment
5. Verdict
A one-off simulator is feasible, but add electrical/mechanical safety, guarding, and a defined motion/software scope; start with a custom prototype and risk assessment.

Against the stated USD 600,000 target retail assumption, one-off tooling is roughly 6–15% of retail. At one unit, it must be priced as NRE; it cannot be hidden in a normal production BOM.
8. Gates to clear
8.1 [DFM]
A one-off build cannot justify bespoke resistance hardware, moulded cosmetics or unproven structural geometry; service access and guarding are often missed.
Path: Freeze a fixed-base architecture, procure a commercial smart trainer and certified power supply, then have a low-volume metal fabricator build welded-frame samples from controlled 2D/3D drawings and a weld fixture.
8.2 [Certification]
No-certification and no-standardisation is incompatible with supply to professional facilities or global sale, particularly where mains power, displays and electronics are fitted.
Path: Define launch countries, then use a compliance laboratory for CE EMC/LVD in the EU, FCC Part 15 in the US for digital/wireless electronics, and UL/NRTL evaluation where facility procurement requires it; assess ISO 20957 fitness-equipment requirements and BIS/QCO applicability for India if included.
8.3 [Tooling]
The unit volume is one, so engineering, fabrication fixtures, software integration and compliance costs are non-recurring expenses rather than amortised production costs.
Path: Quote the project as custom NRE plus unit build, retain catalogue trainer/display components, and release only after the purchaser accepts a prototype budget of USD 35,000–90,000 before the final unit price.
9. Prototype sequence
- 9.1Issue a requirements sheet defining rider range, training use case, installation site, power source, target countries and whether wireless connectivity is permitted.This converts a broad simulator concept into measurable loads, dimensions and an applicable compliance scope.
- 9.2Build an ergonomic mule using a commercial trainer, adjustable bicycle contact points, PC and display.It validates rider fit, resistance range, display placement and software usefulness before custom metalwork.
- 9.3Complete structural drawings, guarding layout, electrical schematic, risk assessment and service checklist.These documents are required to make the custom fabrication repeatable and to support safety review.
- 9.4Fabricate the fixed-base prototype through a qualified low-volume metal shop and conduct static load, stability, emergency-stop and endurance testing.This exposes weld, vibration, fastener and access issues before finish and final electronics integration.
- 9.5Submit the final electrical configuration to the selected compliance laboratory and complete a controlled pilot acceptance at the intended facility.Certification and site acceptance must be completed on the actual final configuration, not an earlier concept build.
