| Cargo-cycle safety standard | Ask which current cargo-cycle standard applies to the exact model and intended market. The EN 17860 series covers safety requirements and test methods for carrier cycles, with applicable parts depending on cycle type and configuration. | Test reports identifying the model, configuration, standard edition, test laboratory, and test results. Confirm that the tested version matches the bike being offered. | A generic “compliant” claim with no standard number, report, model identification, or explanation of scope. |
| Electric-assist compliance | For an EPAC intended for the EU, check whether its electrical assistance meets the applicable requirements of EN 15194. A standard EPAC category generally has a maximum continuous rated motor power of 250 W, assistance that reduces and cuts off by 25 km/h, and assistance linked to pedalling, subject to applicable exceptions such as walk assistance. | Declaration of conformity and supporting technical documentation for the exact electrical configuration. Check the intended country’s rules, as e-bike classifications differ by market. | Conflicting motor, speed, or assistance specifications, or a claim that one configuration is automatically legal in every country. |
| Battery and electrical-system safety | Review the battery, charger, wiring, protection circuitry, and system integration. UL 2849 addresses e-bike electrical systems, while UL 2271 addresses batteries for light electric vehicle applications; applicability and legal requirements depend on the market. | Relevant test or certification records, battery specifications, charger compatibility information, serial-number traceability, and written procedures for handling battery faults and recalls. | Unidentified battery cells, incompatible chargers, missing traceability, or treating a component certificate as proof that the complete bike has been assessed. |
| Braking system | Assess stopping performance for the bike’s intended maximum load, wheel arrangement, and use. Check brake type, lever reach, cable or hydraulic-line routing, adjustment access, and wear-part availability. | Applicable standard test results, service instructions, brake-component specifications, and evidence that the tested bike carried the relevant configuration and load. | Braking claims based only on unloaded tests, poorly routed lines, or no clear maintenance and replacement guidance. |
| Frame, fork, and steering | Check that the frame, fork, steering linkage, kickstand, and cargo structure are designed for the stated use and load. For long-tail or multi-track designs, inspect stability and steering behavior with representative cargo. | Design validation records, fatigue or durability test summaries, production drawings under revision control, and inspection records for welds or other critical joints. | Unexplained design changes, visible damage or inconsistent welds, or no supporting durability evidence for the intended duty cycle. |
| Payload and gross weight | Confirm the maximum permitted rider, cargo, and total system weight. Distinguish cargo capacity from the bike’s maximum permitted gross weight, and check any separate limits for seats, racks, boxes, or individual loading positions. | A model-specific load chart, user manual, load distribution guidance, and test documentation showing how the limits are defined. | One large payload figure with no definition, no rider-weight allowance, or no instructions for distributing cargo. |
| Wheels, tyres, and load-bearing parts | Check wheel and tyre specifications against the intended load and road conditions. Verify rim, spoke, hub, axle, and tyre ratings where supplied, along with replacement-part availability. | Component specifications, wheel-build inspection criteria, approved tyre sizes and load ratings, and spare-parts lead times. | Unspecified tyre or wheel ratings, no replacement guidance, or substitutions that have not been assessed for the bike’s load and use. |
| Production quality controls | Look for documented controls from incoming-material inspection through assembly and final release. Critical checks can include fastener torque, brake adjustment, electrical function, and frame or component identification. | Quality-control plan, sample inspection records, measurement-equipment calibration records, non-conformance process, and model or batch traceability. | Only visual checks, undocumented torque practices, no lot records, or no process for containing and correcting defects. |
| Water and environmental protection | Ask what level of protection is provided for the battery, connectors, display, and control components. Clarify permitted operating and cleaning conditions; an ingress-protection rating applies only to the tested component and conditions stated. | Component-level test reports, care instructions, connector specifications, and guidance for wet-weather operation and cleaning. | Broad “waterproof” claims without a defined rating, test scope, or limitations. |
| Service, warranty, and parts | Evaluate warranty terms, service training, diagnostic support, and access to safety-critical parts such as brakes, batteries, wheels, and steering components. | Written warranty conditions, parts catalogue, service manuals, response targets, and a clear process for safety notices or recalls. | Unclear warranty exclusions, no repair documentation, or dependence on unavailable proprietary parts for routine repairs. |
| Supplier decision | Compare suppliers using the same model configuration, intended market, loading assumptions, and evidence checklist. Prioritize verifiable safety documentation, consistent production controls, and sustainable service support. | A completed comparison matrix with document references, open questions, sample-inspection findings, and named responsibility for resolving gaps. | Selecting on price or specification sheets alone before verifying the actual product, records, and support arrangements. |
