    Some good news! The container vessel arrives late at night tomorrow, and we are still working with shipping agency to plan the unloading and delivery to our location. Also, we want to make sure they don't drop off the container during the holiday, and we can't risk losing a container to some...

    Pinion Motor.Gearbox.Unit (MGU)

    We have considered it, and we have approached some relevant people. The Pinion MGU will enter the North American market only in 2025 as they still need to build their service network here and get the products certified to UL standards. Currently, we are testing the Valeo motor. We typically...

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

    Hi John, The front ring is 55T, and the rear cog is 22 T. If needed we can change the rear cog to 20T. The 22T will last a bit more than 20T because of the larger surface area associated with more cogs.

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

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

    The original estimate for the vessel's arrival in Canada was the third week of March. However, there are many reports that terrorist attacks on commercial ships in the Red Sea and Indian Ocean have caused congestion at other ports. So, we are now expecting the vessel to arrive in the fourth week...

    Of course, The Photon Ultra is available, and this bike is mostly desired by people who have done sufficient research and are willing to pay a premium for the Rohloff hub. So, the Ultra is available in limited quantities. It does come with a kickstand and integrated front and rear lights.

    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...

    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.
