Sodon Sensor

What is a Sodon Sensor on an eBike?

A Sodon sensor is a type of electronic device that is commonly used in electric bikes to measure the speed of the motor and to provide information to the bike’s controller about the position of the pedals and the force being applied to them.

How does a Sodon sensor work?

The sensor works by using the Sodon effect, which is a phenomenon that occurs when a magnetic field is applied to a conductor, causing a voltage to be generated across the conductor. This voltage can be used to provide a “variable switch” used for many applications on the bike.

Where is a Sodon sensor located on an eBike?

In an eBike, the Sodon sensor is usually located near the pedals or the bottom bracket, and it sends signals to the controller that are used to adjust the power output of the motor in real-time.

How does a Sodon sensor affect the performance of an eBike?

The sensor helps to ensure that the eBike operates efficiently and smoothly, and it can also provide valuable information to the rider about their performance and the status of the bike.

Did you Know You Can Convert a Regular MTB to Electric?

Bafang a leader in DIY electric bike conversions has a mid-drive kit that will fit on most regular bikes. I’d recommend the BBSHD kit, it’s a complete setup with a huge capacity battery and a 1000 watt motor. Why this setup?

  • Heavy duty 1000 watt motor (built for cargo bikes)
  • +50 volt 17.5 Ah battery for speed and distance
  • Easy installation with provided tools.

Can I Replace a Sodon Sensor on an eBike?

Yes, it is possible to replace a Sodon sensor in an electric bike. The process will vary depending on the specific make and model of the eBike, but in general, here are the steps you might follow to replace a Sodon sensor:

  1. Gather the necessary tools and supplies, including a new Sodon sensor, a screwdriver, a wrench, and any other tools specified in the eBike’s owner manual.
  2. Refer to the owner manual or a service manual to locate the Sodon sensor on the eBike and to determine the correct procedure for removing it.
  3. Disconnect the battery and any other electrical components that might be in the way of the Sodon sensor.
  4. Remove the old Sodon sensor by loosening any screws or bolts that hold it in place and gently prying it out of its mounting bracket.
  5. Install the new Sodon sensor by reversing the process used to remove the old one. Make sure to tighten any screws or bolts securely and to reconnect any electrical components that were disconnected.
  6. Test the new Sodon sensor to make sure it is working properly. This can usually be done by turning on the eBike and observing the behavior of the motor and pedals.

Replacing a Sodon sensor in an eBike can be a challenging task, especially for those who are not familiar with the inner workings of an eBike. If you are not comfortable performing this type of repair, it is recommended that you seek the assistance of a qualified mechanic or an authorized eBike service center.
