    Awesome. I am glad you're enjoying your bike. To our knowledge, Zen and another brand in Switzerland - Flyer are on the only brands to have two different charge modes built into the bike BMS. The cells used in Photon Pure and Photon Pro models are 21700 format - Samsung 50G. The BMS was...

    Complete Details of Zen Mid-drive Motor - 500W (900W peak) power, 120Nm torque

    This feature will enter the market later this year. We saw the new displays from Bafang and they have dual battery options, Class 1,2,3 can be changed on the display and tune the torque and power curves using the App. This is possible because all peripherals communicate via CANbus. This will...

    Zen Photon Ultra - limited version (Bafang Ultra, Rohloff Speed hub, Gates belt drive)

    We are currently sold out. If you place an order now, the delivery will be sometime in late August. If you can wait until September, then you will be able to use Rohloff E-14 electronic shifting. While I was at the Bafang factory, we tested the new electronic Rohloff system, and it worked pretty...

    Bafang to Rohloff belt drive question.

    Thanks for sharing this excellent analysis! Very helpful for riders. Typically, most motors are tuned to provide high torque and power at around ~75 RPM cadence. This is also beneficial for knees. On my previous bike, I did use 55T and 20T for Rohloff and was able to maintain 23mph average...

    You have very sharp eyes! Because our BMS and charger all communicate on CANbus, we have to use this. When you have CAN, the charger can precisely show SoC and stop the charging process once it reaches the desired voltage and error rate is much smaller.

    We toured the Bafang factory 2 days ago, and the new M560 has a lot of potential for the E-MTB market. I will share more details when I am back in Canada.

    Photon Pro first ride impressions

    The controller is 20A and it can fine-tuned at the factory level, not using the display. See some details of the controller in a post under the Zen motor thread. 👆

    Complete Details of Zen Mid-drive Motor - 500W (900W peak) power, 120Nm torque

    Hey guys, Apologies for the delayed response. Google suite (Gmail, G-drive) doesn't work in China and all our company email and documents are on Google cloud. So, I had to use VPN using spotty mobile data connection and for a week, my Canadian phone data was not working. So, it was challenging...

    Complete Details of Zen Mid-drive Motor - 500W (900W peak) power, 120Nm torque

    @CincyKid and @Gionnirocket , you could be the first in the US to ride an M6100 motor running at 52V, 750W. Let me know if you need any changes done to your bike. I will personally test the unit in about 5 days when I am at the Ananda factory. I believe we can make it very smooth and powerful...

    Zen Photon Pro- Preorder | 1040Wh UL Certified battery | 500W nominal/900W peak power Torque-sensing motor w/ Throttle | USD 2999 | CAD 3999

    Cold temperatures affect the battery range (so do strong headwinds) A decent rider with a fairly even contribution from the motor and the rider would offer 140kms of range in assist level 1 or 2, depending on the terrain. We have several riders crossing more than100kms on a charge.

    Thanks for your note, Johnny. OEMs can update the torque and power ratings on the Ananda motor. While most of their motors operate at 48V, we worked with them to get to 52V and change certain programming. One of the most exciting motors in their lineup for 2024 is an M300. It offers 750W of...

    Bafang Ultra + Rohloff combination - User feedback requested

    Out of all the IGHs, Rohloff has the longest track record and stellar reputation. There have been delays, but they have always maintained an excellent reputation. The 3X3 hub looks promising but there is not enough field data.

    UL Certified Ebikes

    Bosch only has UL-2849. I don't think their 2271 is not valid anymore. I remember speaking with UL, and previously, Bosch had passed UL-2271 with Intertek, and after the revamp of UL-2271, they were on the list for some time, but someone at UL mentioned that "Bosch is there only because they...

    Waiting for photon ebike

    Wayne stopped by our facility this afternoon. As a previous motoryclist, Wayne is liking his transition to E-bikes from motorcycles. It looks like he will rack up at least 4000 kms this summer and lose about 40 lbs at the run rate he is currently going at.

    Zen Photon Ultra - limited version (Bafang Ultra, Rohloff Speed hub, Gates belt drive)

    I will check if both UART and CANbus versions can be programmed from the tool or not.

    Longest lasting tire recommendation

    Schwalbe Marathon Plus would last a long time. We have also had great experience with Schwalbe Super Moto-X tires.

    Zen Photon Ultra - limited version (Bafang Ultra, Rohloff Speed hub, Gates belt drive)

    @Gionnirocket , I did have a chat with the Bafang factory personnel and learned that both 750W and 1000W have the same hardware. The motor armature is capable of handling 1500W continuously. To tune the motor to 1000W, the BESST tool is used to program the motor. From what I have learned, this...
