What should you note about electric bicycles (e-bikes) participating in road traffic?

You answered correctly. Electric bicycles (e-bikes) can be deceptively fast and often look very similar to regular bicycles. This means you should not rely on visual cues alone to judge their speed, as they may approach much faster than expected, and their appearance does not distinguish them easily from conventional bikes. However, they are not easily recognized by their engine noise, because e-bikes are usually very quiet. In traffic situations, always be especially attentive when estimating the speed of bicycles, as they could be e-bikes traveling faster than normal, even if they appear to be regular bicycles. This helps prevent misjudgments and increases safety for all road users.
