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

    Thanks for your excellent suggestion and contribution. I wish Bafang realized the quantum of work enthusiastic riders like yourself have put in.

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

    I don't have enough data on the durability of the Enviolo Heavy Duty hub with Bafang M620. There is enough data on the reliability of Rohloff under high-powred mid-drive systems - [Optibike, Nicolai, Utah Trikes] I don't think the servo motor in the Enviolo Automtiq shifter would be able to...

    Enviolo or Rohloff?

    Stefan, We appreciate your passion for E-bikes, and there is a lot more to Torque ratings than nominal power ratings shared by these E-bike companies. It is a shame that marketing blurb in the E-bike world can be highly error-prone. Have a look at this Torque rating for Harley Davidson Live Wire...

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

    Thanks for your kind words. We have been working hard to support the North American rider community. I am glad our efforts caught your eye. The user can configure the system to US spec, but the liability is on the end user, and we ship it configured according to Canadian laws.

    Zen Photon Pure | 780Wh battery (Upgradable1040 Wh UL 2271 battery) | 750W(USA) 500W(CAN) hub motor w/ Torque sensor & Throttle | USD 2099 | CAD 2599

    @FiremarshallDave , as mentioned here, to reach 28mph requires active pedaling. We want our customers to enjoy pedaling / some workout and don't intend to design bikes meant for throttle use only. We use 2.4" tires on most of our bikes.

    Zen Photon Pure | 780Wh battery (Upgradable1040 Wh UL 2271 battery) | 750W(USA) 500W(CAN) hub motor w/ Torque sensor & Throttle | USD 2099 | CAD 2599

    @FiremarshallDave , the Canadian standard is 32 kmph or 20 mph. All Photon Pure bikes shipped to the US would have a top speed of 45 kmph or 28 mph. The current state of the in 2170 cell is 5300 mAh or 5.3Ah but these cells are too expensive. What we use is 5000 mAh or 5 Ah cells from Samsung...

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

    Gentlemen, Many thanks for your critical insights. I gather that there is a lot of more room for improvement of the pedal-assist technology that works for the North American market. We will work with Bafang to make some of these critical changes.

    Need Help finding the right E-Bike

    The website features accessories used for internal gear hubs like Rohloff and Kindernay. Enviolo doesn't use oil, but Rohloff does. Please see this video here. We are only taking a $999 deposit towards the bike, and any order placed today will be delivered in mid-April. The bike frame...

    Thanks for your kind words, especially coming from someone who has a deep understanding of E-bikes. The early feedback from Photon Pure riders has been very reassuring. A nice outdoor image ....

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

    We are now using 300X thumb throttle which has bit more refinement in terms of throttle response. depending on the use case, the twist throttle can be very helpful.

    Need Help finding the right E-Bike

    Hello, We are a Canadian company, and we have a US website for US-based customers, but our physical presence is in Canada. Photon Ultra uses the Rohloff hub. You will find some more information here in this link. As you can see, we use the Rohloff hub, which is considered the best gear hub on...

    Upgrading from original Himiway Cruiser

    Someone alerted me to this thread. An option you "might" want to consider is the Zen Photon Pro. It does have a throttle, mid-drive motor, Enviolo IGH, step-thru design. There is a detailed thread here. Some pictures below.

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

    as Gionni mentioned, the bike has a throttle (actually, we have improved the throttle hardware from what you see in the picture) and the Rohloff E-shift is only limited to Bosch and Panasonic motors. As of now, no other motor works with Rohloff E-shift. Our Bosch-motor equipped Samurai works...

    The Photon Pure page will be made live next week. We just received some photos, and our website team is working on updating the page.

    At the moment, we do not have that automatic electronic locking feature. We do have an optional IoT that can track the bike using a GPS module and that is something you can consider.

    Zen Photon review

    Thanks for reviewing the bike and sharing your thoughts on the bike and our support. We greatly appreciate it. The throttle response has been consciously kept at the 10-15A current range to encourage people to pedal more. There is another reason for it. Since this bike has a mid-drive paired...

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

    Perhaps we can make use of some suggestions from @smorgasbord and @Gionnirocket to tune the motor to be as smooth as possible.

    We can get you one. This is what we use on our photon Pure E-bikes.

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

    These are some images of the Ultra bike soon after assembly at our factory. you will notice the suspension forks are top of the line - Titan model from RST. These frames arrive in SKD condition and then go through the final QC/QA in Canada. These frames are expected to arrive in Canada towards...

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

    The Photon Pro bike mentioned in this thread or this website link has excellent torque and battery range. The Photon Pure with 20Ah battery would also work quite well. If you have been happy with the torque sensor performance of Juiced, then you will be very pleased with Zen Photon.
