Did I tell you guys the little story of how the Swiss lawmakers killed the throttle? It's tightly linked with the type of helmet that's required. The man on the street will tell you that a bicycle helmet (EN 1078) is all that's needed for a Speed Pedelec. But there's actually a variant that's allowed by the law. To understand it you need to delve into the definition of a Speed Pedelec under Swiss law:
- Electric engine of 1000 watts max
- Max speed by construction: 30km/h
- Max PAS speed: 45km/h + tolerance
Helmet rules for Speed Pedelecs:
- If max speed by construction <= 20km/h an EN 1078 helmet is required
- If max speed by construction >20 km/h an ECE 22.05 helmet is required
If you're wondering what "max speed by construction" means, just substitute with the word throttle.
In other words (for a Speed Pedelec) if your bike's throttle is technically restricted to speeds of 20km/h or less, then you need to use an EN1078 helmet. However if the bike's throttle allows speeds greater than 20km/h, you need an ECE 22.05 helmet. But... even if you have an ECE 22.05 helmet, your throttle's max speed must be limited to 30km/h.
The 30km/h throttle e-bike variant makes so little sense that manufacturers simply decided to throw it out the window. And that's how they killed the throttle in Switzerland.
