Can You Leave An Ebike In The Sun? (Explained)

The electric bike has many components that are not sun friendly or heat in general, and the reason for this is the flow of electric current in the components of the bike

The question comes up: Can you leave an ebike in the sun? In the summer when there is plenty of time to ride your ebike and enjoy the sun

But can leave an electric bike in the sun damage your bike?!

In this post, we will discuss this topic and determine the extent to which heat affects each component of the bike.

Can You Leave An Ebike In The Sun?

As a general rule, it is not recommended to leave your ebike in the sun for more than an hour or two at most, and the reason for this is that there are three components in the bike that are severely affected by the sun’s heat, namely the motor, the battery, and the controller.

On the other hand, two other parts of the bike are affected by a moderate effect from the sun, and they are the bike screen and wires.

Now that we have answered the question of this post directly, let’s get into the details to know the extent to which the sun affects the components of the bike.

1-The Motor.

The electric bike motor, like any electric motor, has the main component of the copper coil and the magnet

These parts, when exposed to heat for a long time, change their properties and expand relatively.

This expansion affects the proper flow of electric current inside the motor, which affects the performance of the electric bike in general.

If you expose the motor of your electric bike to the sun for a long time, you will notice that the electric bike becomes slow.

2-The Battery.

The electric bike battery is a group of lithium cells connected in series, and these cells are managed by a chip called a BMS (it acts as a computer for the battery).

The heat of the sun affects three main areas of the battery.

First, the chemical processes that occur inside each cell in order to extract the voltage are negatively affected by the excessive heat and in this case, the performance of your bike will decrease.

Second: As we mentioned that these cells are connected with metal connectors in series, and these connections are also affected by heat and will cause weak transmission of electric current to each group of cells (in this case, the voltage output will decrease and therefore performance will decrease significantly)

Third: The third part that will be affected by heat is the BMS, and when this part senses the high temperature, it will shut down the battery completely and the electric bike will not work.

The recommended temperature inside the battery should be from 0 Fahrenheit to 30 Fahrenheit.

3- Controller.

The third part of the electric bike that is affected by the heat of the sun is the controller, and this effect can stop one of the functions of the electric bike or reduce performance in general.

Other Ebike Parts that will be negatively affected by the sun.

In this part of the post, we will explain the least parts that are considered to be affected by the sun, not great, but important.

1- LCD.

When the screen of the electric bike is exposed to the heat of the sun, it may affect the internal parts of the screen, which may cause damage to it.

But note that in this case, the electric bike will keep working, but you will not be able to read the data of the electric bike such as speed and battery charge level

2- Ebike Wires.

Exposing electric bike wires to the sun for long periods will lead to the interior copper wires expanding and changing their shape.

When the electric current is flowing there is a possibility that the electric current does not reach well between the electric bike parts and the controller.

Which you will notice by seeing an error 30 on the screen of the electric bike, which indicates a connection problem

Conclusion.

You cannot leave your ebike in the sun for a period of more than two hours at most, so as not to cause the internal temperature of the sensitive components such as the motor, battery, and controller to rise.
