CYC Photon Motor in detail

In the world of e-bikes, choosing the right motor is crucial for an optimal riding experience. The Photon mid-motor from CYC MOTOR sets new standards in this respect. Developed with a focus on durability and efficiency, this retrofit motor offers numerous advantages over conventional models. In this blog article, we take a detailed look at the innovations and technical features of the Photon motor. You can also see the details in the video below.

The Photon motor is an outsider in the world of e-bike motors, literally. As an outrunner motor, the magnets are attached to a ring on the outside of the stator coils. This results in a rotating ring instead of a rotating shaft, as is the case with many other motors, such as the Bafang BBS motors. This design not only ensures more efficient power transmission, but also better cooling and therefore a longer service life.

Another advantage of the Photon motor is the use of steel gears. While many other manufacturers rely on plastic or POM gears, CYC MOTOR deliberately opted for steel to increase the durability and service life of the motor. This minimizes the risk of wear and reduces the need for frequent maintenance.

The Photon motor consists of several essential components, all of which are interchangeable and can therefore be easily replaced in the event of problems. This makes the motor particularly easy to maintain. Let’s take a closer look at the individual components:

• Spindle: The spindle is attached to the unit with a retaining ring. The crank arms are mounted to it on both sides.
• Final Stage Part: This part includes the gearbox, bearings, one-way clutch and torque sensor module. The torque sensor module consists of a stationary and a rotating part.
• Controller: The controller is the brain of the e-bike system. It controls the firmware and processes all signals, including the speed sensor, torque sensor and batteries. It is connected to the motor core and the torque sensor via pins.
• Motor core: The motor core contains the rotating and stationary parts of the motor and is set in motion by current signals.
• First stage part: This component connects the motor core to the final stage part and contains a freewheel clutch that eliminates pedal resistance when riding without motor assistance.

The heart of the Photon motor is its torque sensor. When pedaling, the rotating part of this sensor moves, the signals of which are recorded by the stationary part and forwarded to the controller. The controller activates the motor core, which then transmits the rotation via the first stage part to the final stage gearbox. This is where the chainring is mounted, which ultimately transmits the power to the bicycle chain.

A particular highlight of the Photon motor is the ability to ride with almost no resistance without motor assistance. This is made possible by the freewheel clutch in the first stage part, which decouples the motor core from the drivetrain as soon as the motor is not active.

The firmware on the controller can also be adjusted to the desired riding behavior via smartphone app. Further details and innovations in the chainring area can be found in the video below:

The Photon mid-motor from CYC MOTOR is an impressive innovation in the field of e-bike drives. With its robust design, efficient power transmission and ease of maintenance, it offers an excellent solution for anyone looking for a durable and powerful e-bike retrofit motor. Whether you are a passionate cyclist or a technology enthusiast, the Photon motor could be just the thing for you.
