What Is A Motorcycle Blind Spot Monitor And Why Do We Need It?

One’s life is dear to one’s self. We will go to extreme heights to protect our life. If a motorcycle blind spot monitor ensures our lives and vehicle safety, it is right to call it a necessity. Keep reading to observe how a motorbike blind spot system works and keeps us safe.


A motorcycle blind spot monitor is technical equipment that observes the blind spots of a motorbike. Moreover, it detects any moving object in a specific area and warns the rider about it. Also, some advanced detection systems can effectively monitor the target object’s speed, displacement, and distance.

Some of the primary functions a typical motorcycle blind spot monitor has are as follows:

  • Monitoring the right and left sides for any risky moving object.
  • Accurate detection of the object and alarming the rider.
  • Measuring the vehicle’s speed and the target’s relative displacement to judge whether it is a risk.

Keep in mind that some of the motorcycle blind spot systems work only above a specific speed. The general functioning range of these systems is 10km/h to 25km/h.

Blind Spots Of A Motorcycle And How Does A Motorcycle Blind Spot Monitor Keeps An Eye On Them?

While driving a car or riding a motorbike, any spot on the road that is invisible to the driver or rider’s eyes is under the category of blind spots.

Every car on the road has some blind spots that can be a potential hazard. Consider it a structural drawback. The same is the case with motorbikes. Every motorcycle has several blind spots that are entirely invisible to the rider’s eyes. Some of these blind spots are:

● Lower Left And Right Sides:

It is one of the smallest yet most dangerous motorbike blind spots. While riding a motorcycle, the rider has to look forward mostly. In that condition, Both left and right sides become a no-zone for the vehicle.

To monitor these, most of the riders use side-view mirrors. However, these are not enough to observe the designated area of the blind spot. That’s why even after using mirrors, there are chances that you can miss something from the no zone.

The ideal method is to use a motorcycle blind spot monitor. It detects the approaching vehicle early and warns you about it. The vibrant flashing warning light makes you cautious about the vehicle that is about to overtake.

● Rear Portion Of The MotorBike:

It is the biggest and most dangerous blind spot on a motorbike. People usually ignore it as there isn’t any active motility around the back. So, it makes them completely unaware of any rapidly approaching vehicle and increases the hazard.

Helmets tend to increase the area of this blind spot. For that reason, Without a motorcycle blind spot monitor, you can only look around by turning your head. No side-view mirrors will come in handy in this situation.

Taking your eyes off the road to check the rear view isn’t a great choice. That is why blind spot systems are always the priority.

What Parts Do A Motorcycle Blind Spot Monitor Have And How Do They Work?

The parts of a blind spot system affect its functions, range, and general mechanism. Every part of the vehicle performs a particular function. So, along with the change in the technical capability, comes a change in the intensity of that function.

Some of the parts of the motorcycle blind spot monitor and their functions are as follows:

1. Millimeter Wave Radar:

The wave radar is the primary and most basic part of the blind spot system. It is a wave transcoder that emits radio waves or microwaves. These microwaves help in the detection of target objects in the alarm area.

Functioning Of Millimeter Wave Radar Of Motorcycle Blind Spot Monitor:

As mentioned earlier, the blind spot radar emits microwaves that can reach only the specific detection area. These waves continuously oscillate in the area and maintain a non-electrical connection. If any target object enters the area, it interferes with the waves, and as a result, it gets detected by the radar.

2. Indicator Lights Of Motorcycle Blind Spot Monitor:

After the target object’s detection, the next step is to alarm the rider. The motorcycle blind spot system makes it possible by flashing indicator lights.

Every motorbike blind view monitor has a pair of indicator warning lights. Whenever any one of these lights flashes, it alarms the rider about the incoming danger from the corresponding side.

3. Wire Harnesses Of Motorcycle Blind Spot Monitor:

Along with the detection and alarming parts of the product, some wires help to install them. These wires are called wire harnesses of the respective part. Such as

  • Radar Wire Harness
  • Indicator Light Wire Harness
