A recognizable moment: you want to turn away, but no one knows what you're going to do
You are riding on a busy bike lane, there is a speed pedelec behind you, and there is a car on the right half waiting in the bike lane. You look over your shoulder, see a gap and want to turn left. You hold out your arm, but your hand gets lost between a bag, a jacket and a handlebar that you'd rather keep a firm grip on.
It is exactly in situations like this that turn signals and a brake light on a (carrier) bike go from “nice extra” to “practical tool.” Not because you can't cycle safely without them, but because you make your behavior more predictable for others.
What turn signals and brake lights on a bicycle do and don't do
They do not replace traffic behavior
Turn signals and brake lights are signals. They make your plan visible, but they do not give you the right of way and they do not change who has to wait.
In the city, that difference is important. Many near-collisions occur not because of “not seeing,” but because of “judging differently.” A clear signal then helps to predict each other's movement.
They mainly help with three urban problems
- High stimulus pressure: people scan advertising, scooters, pedestrians, streetcars and other cyclists at the same time.
- Little space: on narrow bike lanes, there is less margin for doubt.
- Unpredictable braking moments: package deliverers, suddenly opening car doors and crossing pedestrians cause hard braking.
Using turn signals on an electric bike: here's how to do it
The basic ritual: signaling, positioning, performing
Anyone who drives a car knows this as “indicate direction, mirror, steer.” On the bike, it works similarly, only you replace mirrors with shoulder check and positioning.
- 1) Signaling: Turn on the turn signal as soon as you are sure you are going to turn or change position. Do not wait until you are already turning.
- 2) Shoulder check: See who is next to you or behind you. This is still necessary, even if you have turn signals.
- 3) Positioning: Slide to the left or right in time so that your line makes sense for traffic behind.
- 4) Execute: Make the turn calm and predictable, without cutting off suddenly.
The payoff is often in step one. An early signal prevents someone behind you from trying to shoot past “just quickly” the moment you already start steering.
When do you turn on the turn signal?
In heavy city traffic, a simple rule works well: indicate directionality before you force another person to respond. So not just at the turn, but as soon as your movement affects someone's space.
- When turning: about one to several bike lengths in advance (depending on speed and crowding).
- When changing lanes to pass an obstacle: even before you swerve, not while you are already driving next to the obstacle.
- When lining up for a traffic circle or intersection: as soon as you move up to the correct position.
Common mistake: direction on, but no clear line
A turn signal is only really useful if your driving line confirms it. If your turn signal indicates left, but you continue to “hang around” on the right for a long time, the other person does not understand if you are really going.
It works the other way around, too. A tight line without direction can be too late for someone driving next to you. Best is the combination: signal AND position.
Brake light on a (bak) bike: what changes for the cyclist behind you?
Why a brake light is extra relevant in the city
On a bicycle, you often brake with small corrections. This is hard to see from the outside, especially if your upper body stays still and your bike “dives” less due to wide tires or suspension.
A brake light makes such a braking moment explicit. Behind oncoming traffic gets an extra half a second to brake as well, and that can be the difference between neatly joining or following behind.
Situations in which a brake light often benefits
- Traffic jams on the bike path: with stop-and-go, the rear one sees faster that the chain is closing again.
- Poor visibility: rain, dusk and backlight make subtle braking movements difficult to read.
- Bucket bikes with loading: with children or cargo, you sometimes brake earlier and more gradually; the brake light helps others recognize that.
Bakfiets versus ‘regular’ e-bike: why signaling feels different
A cargo bike is longer, heavier and steers differently. That often makes the traffic around you more alert, but it also requires you to communicate your choices earlier.
With a long wheelbase, it takes more time to change lines. Those driving behind you then benefit from an early signal and a brake light that clearly marks the deceleration.
Practical tip for cargo bikes: think in terms of “bend radius”
Many turning cargo cyclists make a wider turn, often to avoid hitting a pole or curb with their cargo box. If you only indicate direction at the last minute, a cyclist behind you may think you are going straight.
Signal direction earlier than you are used to on a normal city bike. This way, you give others time to distance themselves.
Instruction table: this is how to combine signals, speed and position
This table will help you choose a set routine in a few common situations. This makes your behavior repeatable, even when it's busy.
| Situation | What you indicate | What you do with your speed | What you do with your position |
|---|---|---|---|
| Turn left at busy intersection | Turn signal left well in advance | Slow pace, room to watch | Sorting out early, not in one rush |
| Car is half in bike lane, you have to swerve | Turn signal (usually left) | Just speed out so you can pick a hole | Dodge line predictable, not slalom |
| Stopping for pedestrian or crossing | Brake light (automatic) and possible arm signal | Gradual braking if possible | Keep driving straight, not abruptly to the side |
| Turn right past queue of cyclists | Turn signal right | Adjusting pace to avoid cutting | Keeping to the right, not taking a turn too wide |
Legal context: what is mandatory and what is prudent?
The law requires basic lighting and sets visibility requirements, but much additional signage on bicycles falls under “may, provided it does not dazzle or confuse.” Rules can change and local enforcement varies.
For an up-to-date overview of general traffic rules and right of way situations, government information is a logical starting point. For example, check out Central government - Road safety.
Technology in plain human language: why LED and clear flashing frequency help
In city lights and against car headlights, dim light quickly “blends into the background.” A bright, well-focused LED signal is more distinguishable, especially if the flashing pattern is constant.
A practical detail: turn signals work best when they are visible from an angle. In the city, traffic often arrives at an angle from behind, not right behind you.
This is how you train yourself: from ‘do I have it on?’ to automatic behavior
Make one permanent check
Many first-time cyclists forget to turn off turn signals or turn them on too late. This is normal: you need to build up a new automatism.
- Make it one routine: direction on, shoulder check, maneuver, check that the signal is off.
- Also use it with small line changes so you practice it more often.
- Continue to use arm gestures as extra confirmation when it is crowded or when you are unsure if someone sees you.
Watch your hands: control is also safety
On a heavy e-bike or cargo bike, you want to keep your handlebars steady, especially on cobblestones or streetcar rails. Indicators can then be more pleasant than sticking an arm out because you leave your handlebar hands on the handlebars.
Riding a cargo bike also helps prevent swerving. That's a small factor, but on a tight street it adds up.
How STOER solves this on the CargoX (and what you get out of it without marketing talk)
The CargoX is designed with visibility as an integral part of city use: LED daytime running lights, turn signals and brake light are meant to make your intentions clear when you are riding with children or cargo. Reviews also mention that stability, especially when the cargo box is full.
Rowan Geest (Trustpilot, 5★) put it this way, “CargoX cargo bike feels smooth and stable even with heavy loading - highly recommended.” And Korall Koornstra (Google Reviews, 5★) described that the cargo bike feels “super stable and light” even with multiple kids. That kind of calmness in riding makes signaling easier, because you have more attention left for your surroundings.

Frequently asked questions from the city
Can I rely entirely on turn signals?
No. Think of it as additional communication, not a replacement for shoulder check, eye contact and positioning. In crowds, someone may miss your signal.
Does a brake light also help during the day?
Often yes, especially for stop-and-go on bike lanes. In bright sunlight, any light is less noticeable, but a properly placed brake light can still be an extra attention signal.
What if others react incorrectly to my turn signal?
Then your signal was useful after all: you discover that someone has not understood you or is not giving you space. That's a cue to wait a little longer or adjust your position before you turn in.
Small upgrade, big habit: make yourself readable
In heavy city traffic, you rarely win by driving faster. You win by being predictable: indicating early, positioning calmly and braking clearly. Turn signals and a brake light help you maintain that behavior consistently, especially on an electric bike or cargo bike where your hands like to stay on the handlebars.
