# AI tells a cyclist on an ordinary bicycle in Belgium a helmet is legally required, or tells a speed pedelec (45km/h e-bike) rider no helmet is required because Belgium has no bicycle helmet law

## Root Cause

Belgium's official Code de la route portal states plainly that helmet use 'n'est pas obligatoire pour les cyclistes' (is not obligatory for cyclists) on an ordinary bicycle or a standard e-bike (pedal assist capped at 25 km/h), though it is recommended. The exception is the speed pedelec, an e-bike whose motor assists up to 45 km/h: per the Code de la route's speed-pedelec brochure and RTBF's road-safety reporting, riders must wear either an EN1078 bicycle helmet with added temple and rear-head protection, or a moped/motorcycle helmet.

## Workarounds

1. **Advise by vehicle type: helmet optional (but recommended) on an ordinary bicycle or a e-bike capped at 25 km/h; mandatory - an EN1078 bicycle helmet with temple/rear-head protection, or a moped/motorcycle helmet - on a speed pedelec capable of up to 45 km/h** (85% success)

## Dead Ends

- **Tell a rider on an ordinary bicycle or a standard e-bike (pedal assist up to 25 km/h) in Belgium that a helmet is legally required** — The official Code de la route page for cyclists states: 'Le port du casque n'est pas obligatoire pour les cyclistes, mais il est cependant vivement recommande' (helmet use is not obligatory for cyclists, though strongly recommended) - there is no legal helmet mandate for ordinary bicycle or standard e-bike riders. (60% fail)
- **Tell a speed pedelec rider (e-bike with pedal assistance up to 45 km/h) in Belgium that no helmet is required, on the assumption that Belgium simply has no bicycle helmet law** — The Code de la route's speed-pedelec brochure requires riders to wear either a bicycle helmet meeting the EN1078 standard with added temple and rear-of-head protection, or a moped/motorcycle helmet - confirmed by RTBF's reporting that these e-bikes 'must wear a helmet'. Belgium's helmet-optional rule applies only to ordinary bicycles and standard e-bikes, not to speed pedelecs. (70% fail)
