    @etchlings , @srl1_sd , We will install the Enviolo Automatiq on the Photon by the end of this month. A couple of comments: We have tuned the motor such that its torque sensor is smooth and the initial engagement is relatively quick. Because the motor has much more power than Bosch, we wanted to...

    Some local customers here in Canada, who had pre-ordered it, received the bike last week. This gentleman had a few other brands, finally tired of dealing with chain/derailleur maitnenace on his bikes (Canada has a lot of road salt during the winter months), he was thrilled to be able to ride a...

    Some of our earliest pre-orders are being shipped next week. @msdisme , the riding position quite upright and you could make it a hybrid style because of the stem adjustability. The front rack holds 15kgs. The motor is a custom version made for us and the parts are readily available. The...

    Thanks, @Jeremy McCreary Happy to coordinate with any shop of your choice. We were focused on building the best bike possible, so we are a bit behind on signing up new dealers, but more than happy to coordinate with a shop if you could suggest. Our goal is to ensure serviceability and support...

    Comparison in definitions: Tested To, Complied To, Certified To, UL Certified

    It would be great to have a list of E-bike companies whose batteries are UL-certified by UL, not SGS or Intertek.

    We have dealers on the east coast but don't have a presence in California. If you know of any shops or dealers that might be interested, please drop us a line; we would be happy to work with them. The bike weighs ~ 27kgs without the battery. The battery is about 5kgs. Most of the weight is...

    Dual Battery Balancer circuit - experiences!

    We will have to engineer a solution like that, and it can be done, but it would cost $500K to get this into production. Bosch has done an excellent job!

    Dual Battery Balancer circuit - experiences!

    Public Safety Announcement (PSA): The dual battery function is a favorite among many riders, and being able to connect 2 batteries and extend the range is an excellent feature. This is one of my favorites too. Bosch has implemented this in an excellent manner, and it works very well. But, I...

    Sure, we can make that happen if you are interested. We would test it first and make sure it works very well. I know some other brands have had issues with the Automatiq shifter. Have you tested one and liked it?

    We actually have UL-2849 and UL-2271 documents, and I will share the details shortly. From what I remember: Batteries must be able to withstand over-charging, over-discharging, short circuit, imbalanced charging, and operation at a maximum specified temperature. The enclosure must be resistant...

    Zen Photon - [1000Wh] battery, [500W/120Nm] Torque-sensing motor w/ Throttle, USD 3799 [Pictures and Specifications]

    We had a lot of requests for a bike with a belt-drive and Internal gear hub combo (low maintenance), a long-range battery, and a torque-sensing motor with throttle. So, we created one - Zen Photon. As we set up a battery manufacturing facility in Canada, it will help us offer higher-quality...

    We are very aware of other competitors in the field and not intimidated by any because we are in it for the long haul. It is not just about selling some bikes now but who will have the best technology and product support down the road. Frey released their bike after we showed some renderings...

    'Zen Skunkworks' - a new model in the development

    The BMS used on the Zen Photon is a tier above most common E-bike batteries. Built to UL-standard, we belive it offers better safety. Instead of rat nest of wires running for balance leads, everything is built into a large PCB board. Actual pictures of the Photon battery taken apart.
