    Bafang's Proprietary Battery Port?

    Data communication needs 4 pins; 2 pins for voltage and 2 pins - CAN-hi and CAN-lo for the CANbus protocol to communicate with the BMS. A single pin will not be able to make use of the CANbus, and in most cases, the third pin is typically used for temperature sensing. Grin tech has a wonderful...

    Bafang's Proprietary Battery Port?

    Our team will get this resolved. This is a common connector used in several EU brands. With the nascent state of the E-bike industry, lack of standardization has led to a variety of charge port designs and as the market matures, we will see EV-grade charge ports for micromobility devices. It...

    What is the expected lifespan of the Bosch drive unit?

    Brose has internal belts and they require replacement every 8-10k kms. Bosch has nylon and metallic gears.

    What is the expected lifespan of the Bosch drive unit?

    This is very impressive! The motors last a long time. One of the few instances where it runs into issues is in very humid conditions, i.e., coastal areas with seawater - this can damage the bearings and lead to rust/corrosion. In motors equipped with internal belts, timely replacement of belts...

    I would love some suggestions for the right e-bike for me

    Thanks for bringing this to my attention. I did not realize this had happened. I spoke with our support team to avoid such intrusion in other threads and contribute useful information when specifically asked for. It is never our intention to butt into some conversation and this will not be...

    Forgot to mention. The front light on the Photon has been updated as well. This now comes with 400 lumen light instead of 200 lumen. It also has daytime running lights for visibility. So, with two CREE LED bulbs, the light provides ample luminous flux for night time riding.

    It’s got some heft to it. The large 52V, 20Ah battery 🔋, Enviolo heavy duty CVT hub, reinforced frame all contribute to the weight. With 20Ah battery on the bike, front rack installed, Schwalbe Super Moto X tires, it weighs 74lbs. Without the front racks, using Schwalbe Johnny Watts tires...

    We can answer that. 2024 model will have 4-piston Tektro E-725 brakes with 203 mm rotors both front and rear. It wil have full UL-certification from UL itself. Many companies get this "certification" or "testing" from third party agencies like SGS or TuV but we worked with UL directly to get...

    Serial 1 from Harley Davidson sold to LEV manufacturing/ Life EV (formerly Prodeco Tech)

    In a strange turn of events, Serial-1, an E-bike spin-off from Harley Davidson, has been sold off to LEV manufacturing. LEV Manufacturing was formerly known as Life EV, which sprung from Prodeco Tech (one of the earliest E-bike companies in the industry). This sale shows the difficulty of...

    Replacing your car with an E-bike is a great idea. Reminds me of this article: https://theconversation.com/the-worlds-280-million-electric-bikes-and-mopeds-are-cutting-demand-for-oil-far-more-than-electric-cars-213870 We are right here in Halifax, Canada, and we designed the bike to perform in...

    We have both 17" and 19" frame sizes. For anyone under 5ft 10", a 17" frame is a much better option. We could also install a 15Ah battery instead of a 20Ah one to lower the weight. We would be happy to work with Earl's bike shop in Bellingham and coordinate the assembly and service.

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

    Yes, it will easily handle that. Every component on this bike is designed to handle heavy-duty usage. We have a few customers over 250 lbs and have no problem riding up steep hills.
