What is a throttle grip?
A throttle (also called a thumb throttle or twist throttle) works similarly to that on a moped or e-scooter. You don't have to pedal to move forward — instead, you control the speed directly with the handle. Depending on the model, the motor is activated continuously or at fixed power levels.
That sounds tempting, especially for people with physical limitations or when starting on a hill.
Difference to pedal assistance
Most e-bikes, as we know them from everyday life, have pedal assistance: The electric motor only provides assistance when you pedal. Assistance ends at 25 km/h; beyond that, you continue riding using muscle power alone. Such models are legally considered bicycles and can be used without a driver's license, insurance, or helmet.
Things are different with the throttle: Since the motor can be activated without pedaling, the e-bike is legally classified as a small motorcycle or moped – with corresponding consequences.
Legal situation in Germany (StVO)
In Germany, the Road Traffic Licensing Regulations (StVZO) regulate what is permitted and what is not. The following applies:
-
A throttle grip is permitted up to 6 km/h – for example as a starting aid, e.g. when starting on a hill or when pushing.
-
From 6 km/h without pedal assistance, the e-bike is no longer classified as a bicycle, but as a moped.
This has the following consequences:
-
Insurance number plate required
-
Operating license required
-
Helmet requirement
-
Minimum age (from 15 years with moped test certificate)
-
No use of cycle paths permitted (unless explicitly approved)
For the vast majority of e-bike riders, this is practically not suitable for everyday use, as the bureaucratic and financial effort increases – and the benefits are relatively small.
Examples from other countries
People are often much more relaxed abroad:
-
Netherlands: Here too, throttle grips are only permitted at a maximum of 6 km/h – but enforcement is loose.
-
USA: Throttle-equipped e-bikes are widely available . Depending on the state, they are considered a separate class of electric bicycle.
-
Great Britain: Throttle grips are permitted up to 15.5 mph (25 km/h) – provided the bike meets certain requirements.
-
China: For a long time, e-bikes with pure throttle dominated – now there is a greater shift towards pedal assistance.
This shows that the registration regulations vary greatly – anyone traveling abroad with an e-bike and throttle should find out more beforehand.
Models with throttle grip
Despite legal restrictions, there are e-bike models with throttle grips on the market – often called S-Pedelecs or hybrid solutions. Examples:
-
Fatbikes or cargo bikes with push assistance
-
US import models – however, often not road legal in Germany
-
Retrofit kits with throttle lever – legally tricky and not permitted without an operating license
Conclusion: Only useful if...
A throttle on an e-bike is only useful if you use it as a starting or pushing aid — that is, for short bursts up to 6 km/h. Tip: MYVELO folding bikes have a starting aid .
However, anyone who relies on a full throttle function without pedaling leaves the “bicycle” category in Germany and has to deal with small motorcycle regulations.
