    * Attention Juiced Bikes Community *

    This is valuable information. We now have all the necessary items needed for building the battery, but what we are struggling with is the lack of a 3D drawing of the battery case for us to validate our design. I will reach out to Lectric folks later today. Thanks

    Zen - 2025 updates from Halifax, Canada

    Zen had been quiet for the last seven months, and that is mainly because we were neck-deep in setting up our battery factory. Starting the first week of August, we will deliver approximately 300 batteries every month to the E-bike division and to our US distributor in Ohio. We now have true...

    Our service manager, Mohammad, is truly an excellent one. Please send him a text message or give him a call at +1 (902) 635-4777. He has been working with component suppliers (motor, Enviolo, and Gates) to understand what might have caused this and how to resolve it once and for all.

    New Zen Samurai:)

    This is a neat solution! Thanks for sharing. We used RackTime systems before, and we thought it was sturdy, but nothing beats an integrated aluminum fender that is attached to the frame.

    3x3 hub and a Bafang ultra motor

    Thanks for your note. We are building two samples. E-bike production suffered a substantial hit due to tariffs and global trade disruptions, but given experiences with Enviolo, Rohloff, and Kindernay, we are in a much better position to assess not only the product quality but also long-term...

    ZEN Customer Service

    Thanks for your kind words and for sharing an honest review of your experience. We are neck-deep in building our battery factory, with an installed capacity of 3,000 e-bike batteries per month. This required an insane amount of work, and we have finally built a complete engineering team...

    ZEN Customer Service

    Tom, we are not advertising Kindernay. It is just that the website had not been updated. In June, we updated the website and removed Kindernay, despite having 7 Kindernay hubs in stock and some parts as well. Currently, we only offer Enviolo and Rohloff, both of which are well-supported. Our 3X3...

    Known Issues & Problems with Zen Products + Help, Solutions & Fixes

    Hey, I believe Mohammad is already working with you. The new motors at 160Nm are not being friendly to Enviolo, and we are seeing this in our experience. We will reduce the torque slightly to prevent Enviolo cables from being under stress during the shifting process but peoeple like high torque...

    Why Charge to 80% and the use of smart BMS in Zen 52V,20Ah UL-2271 battery

    We do our own extensive testing. We have tested major E-bike batteries, including Bosch. The testing includes cycling at 35 degrees C and 45 degrees C, and based on this testing data, we are confident of offering 3-year warranty on batteries. You can see our batteries being tested in the second...

    Why Charge to 80% and the use of smart BMS in Zen 52V,20Ah UL-2271 battery

    Our BMS balances the cells even at 50% state of charge. The primary reason for charging to 100% is to recalibrate the BMS for accuracy. It is good to charge to 100% once a month and then draw it down. So, the BMS knows what is true 100% regarding voltage.

    Why Charge to 80% and the use of smart BMS in Zen 52V,20Ah UL-2271 battery

    One of the features that we have implemented in our Photon Pro and Ultra bikes with 52V, 20Ah batteries is the smart BMS with the adjustable limit for an increased lifetime. These modes can be changed with the simple click of a button on the control display. I don't know of any other E-bike that...

    Logistics - what a pain!!

    @John A. Tomasino , @Kriti Yad and I are very grateful for your patience. Your bike and 3 more bikes are the ones that have gone back and forth with the Customs and Border Agency on two round trips. We have spent over $500/bike with UPS just for these back n forth to the border. The last time...
