Fast or slow?
In addition to the fact, that a helmet must on fast e-bikes (which should actually always be the case per se), the difference is mainly in the awareness, the price and the customization options. 45kmh e-bikes require a road registration, a yellow number and at least one moped driver's license ("M", is included in the normal driver's license too). Minimum age is 14 years. The road approval makes the procurement process more expensive and makes most individual modifications to the bike impossible, since it has to be used as approved by the Federal Office. A fast e-bike also includes conscious handling of the vehicle. Braking distances are significantly longer (3x at 45kmh), accidents more dangerous. The situation is similar when the bike wears out. Reason not to buy a fast one? No. I don't have to be on the move at top speed all the time, I can also move around relaxed in the comfort range of 25-30kmh. For many, the lack of support after 25kmh is an abrupt breakdown among the slow. However, the 25s offer the advantage of being out and about with a normal bike and are cheaper in terms of purchase and maintenance costs. Rule of thumb: urban, short and medium-haul routes tend to be slow (the 30 zone also applies to bikes !!!), overland routes tend to be fast ... We do not recommend an e-bike for older citizens who have no experience with normal bikes.
