The Photon from CYC Motor in Hong Kong, is a dream product for electric conversion builds.

If you want to convert your existing bike, rather than buy a brand new one, then this is the best quality motor you can get.

Advanced torque sensing technology from CYC offers a seamless, intuative pedal assist experience (comparable to Shimano EP8 or Bosch CX Motors). With a helical gear design, the build quality is uncompromising, but also manages to keep the noise down. This motor is compact, lightweight, and offers bike modders a premium option for their next conversion project.

Retrofit Mid Drive Motor Comparison

CYC vs Bafang

At Paradise Cyces, we have been using the Bafang BBS02 motors for over 2 years, and found it to be excellent value, powerful, and predictable (when configured sensibly). However, the differences between a cadence sensing motor (Bafang) and a torque sensing motor (CYC) is noticeable. The CYC Photon is going to be a game changer.

We have ordered a batch, and will continue to test these two systems against each other throughout 2023.

Which is best? Bafang BBS02 or CYC Photon

For all road based use, the Bafang is absolutely fine and can't be beaten in terms of cost and customisation. With the custom tuning profiles that we have developed, you get maximum range as well as a smooth, predictable behaviour at >5mph. The downside is low speed control, where you need to either use the brake sensor to cut the motor, or breifly switch the PAS level to 0.

If you are using the kit off road (for trails or bike parks) and you need faster cut off + enguagement for technical riding, and you need a chainring smaller than 40t, or want a simpler and slightly easier to use system, then the CYC Photon is the way to go.

What CYC have to say

New CYC motors are equipped with the Gen 3 torque sensing technology exclusively developed in-house by our team of engineers and riders. Together they achieved a pedal assist experience for conversion kits like you've never seen before! 

Equipped with our patent pending torque sensor module, we can give you a refined pedal assist system. The torque sensor module includes both a high sensitivity torque sensor strain gauge module and a cadence sensing module. The high number of poles of the cadence sensor ensures that we can control the sensitivity to a much higher degree & provides the opportunity to fine-tune the firmware alongside rider inputs. The result? Unprecedented ebiking! 

Our PAS firmware algorithm is like the secret ingredient in a top chef's recipe. Without it, we'd be boring! BUT, we aimed for better, and so, we've accomplished it! Our engineers were put to the test and are proud to present you with an all-new pedal assist experience.

The new Gen 3 PAS (pedal assist system) sits integrated with the robust sprag clutch module so there's no external wiring that can get caught, bent, or accidentally snapped. The CYC PAS runs with both the torque and cadence signal collected and is processed by the controller to provide you with a pedal assist feeling like never before.  

Not only have we written our firmware alongside our team riders, we've made sure that that all our MVPs got a chance to test it! This includes our partners at Ristretto Electric, Coast Cycles, Fasterbikes EU to name a few. We also showcased the beta version at the 2022 EUROBIKE show where the feedback was phenomenal!
