What the law counts as an e-bike
EU Regulation No 168/2013 does not treat as a motor vehicle a pedal-assisted cycle whose motor has a maximum continuous rated power of 250 W, assists only while pedalling and cuts out progressively and finally by 25 km/h. Such an e-bike needs no type approval, registration or driving licence.
Bikes assisting faster or stronger (speed pedelecs up to 45 km/h) fall outside this exemption; they are category L vehicles with type approval and all the duties that brings.
What to look at
- Bike type: city and trekking for roads and firm paths, mountain (hardtail or full suspension) for off-road.
- Mid motor (at the pedals): a balanced bike and natural pedalling, better uphill. Hub motor: cheaper and simpler.
- Battery (Wh): capacity in watt-hours sets the range. Real range depends on assistance level, hills, rider weight and temperature; makers state a span.
- Removable battery: charge it at home when the bike lives in a cellar or on a balcony.
- Frame size: by height and inside leg, the maker has a chart; a wrong size is not fixed by a motor.
- Brakes: hydraulic disc brakes are standard on a heavier e-bike.
- Service: availability of service for that motor and battery; a spare battery is among the dearest parts.

Price history
Older model years (bikes carry the year in the name) are often cheaper in autumn and winter; check it is a new bike, not an ex-demo.
Common mistakes
- Buying by motor power; above 250 W or with assistance beyond 25 km/h it is no longer an ordinary e-bike under EU law.
- Comparing bikes of different frame sizes; the size is often right in the offer title (S, L, XL).
- Trusting the maximum range; expect less, especially in winter and hills.
- Not counting bulky shipping and the first service.
- Leaving the battery out in the frost and charging it cold.
Häufige Fragen
Do I need a licence or a number plate for an e-bike?
No, if it is a pedal-assisted bike up to 250 W whose assistance cuts out by 25 km/h. Faster bikes are category L vehicles with other rules.
How far will I get?
It depends on battery capacity (Wh), assistance level, hills, weight and temperature. Makers state a span; expect less in winter.
Mid motor or hub motor?
A mid motor is better uphill and off-road and rides more naturally. A hub motor is cheaper and enough for a flat town.
Must I wear a helmet?
Cyclists under 18, yes. The law does not require one for adults, but at e-bike speeds it pays.
