Nope. You would be able to track the battery, and this feature makes it difficult to steal the bike. Moreover, the amount of insight you can get from telematics is fantastic. We could handle about 1 million data points per device per hour. So, this provides accurate control over the state of...

At the moment, we are only looking at 52V. Not at the moment, they will be available Q-1 2025, and they will be UL-2271 certified and come with built-in 4G telematics and GPS and a suite of advanced safety features.

Our new 52V, 20Ah battery design would provide an excellent alternative for Hailong, Dolphin, Shark / DP-5 from Hailong, and other cases normally found on DIY E-bikes. People in the DIY world deserve a well-engineered battery pack. I am curious to hear from EBR readers about the color scheme...

Our new battery in 2025 will have Tabless cell and can be charged at 1C and still get 2000 cycles. The problem is there are not many chargers that can charge at 20A. Our pack will handle 10A charging all day long.

It has been a dream for a few years and has taken a lot of work, but finally, we are super excited to announce our battery mega factory in partnership with Greenfuel. An official press release will be out next week, and I am sharing a sneak peek for Zen customers on EBR. I have been silent here...

This is totally normal. A bit of fiber frayed at the edges is normal, and this is from small rocks and chips. Gates belt typically lasts about 8000 to 10,000 km, depending on the power level used and maintenance interval. It would help wash the belt with a simple (NON-pressure) washer-like...

We think people ultimately benefit from a longer life than a longer range. Even at 80%, the bike offers more range (~90 to 100 km) than what people are used to riding in one go. So, we prioritized long-life and it defaults to long-life mode each time. This is also the reason why we are able to...

Correct. To change the charge limit to 100%, the CAN signal needs to come from the controller via the display. Without this CAN signal, the BMS will not be able to switch the charge modes. We wanted to implement it so that it can also be changed when the battery is off the bike, but that would...

Yes, we have a battery (internal tube version) that works perfectly with DOST downtube. The auxiliary battery used by DOST is a bit different. If there is enough demand, then we make it available but we know exactly how it is designed and the communication protocol.

Press and hold the (+) button to turn on the headlight Check the light connector under the spiral wrap is firmly seated (sometimes, a loose connection here is the culprit) The rear brake light should irrespective of the head light mode

Thank you for this incredibly detailed post and for documenting it so thoroughly. Very few people do this level of due diligence before purchasing an E-bike! A few points to add to your post regarding 2024 Photon Pro version 2: We have found that many people really like the beryl green color...

The rims are tubeless ready, and tubeless conversation can be done by any competent bike store. It is worth considering if you are riding on rough terrain, but otherwise, the Super Moto-X should do the job.

I had a discussion with the director of UL, who oversees the E-bike division. They seem to be committed to holding high standards when it comes to UL-2271 and UL-2849 standards. From our own experience, it is clear that UL holds a more stringent standard than other labs. There are certain...

While we were at Bafang, the media team told us that GMBN would visit them shortly. For years, Bafang was seen as a DIY kit supplier; now, they are opening up to a larger OEM market more substantially. Here is a video of GMBN about Bafang.

Zen team is excited to share the UL-2271 certification for our batteries. We take safety and E-bike battery quality very seriously and we invested significant capital to ensure our customers can charge their batteries without worrying about safety. Recently, E-bike battery fires have caused many...

The author can Zen E-bike batteries to the list as well. We now have official certification from the UL labs. It will get updated on the UL database in about 1-2 weeks.

Great to hear that, John! Wishing you thousands of miles of fun and happy memories on the Photon Ultra.

Let us know if anyone has trouble sourcing parts related to Bafang. Our team would be happy to help.

I believe we connected last week, and our service personnel might have spoken with you regarding the belt tension. Please let us know if you need any further assistance. @DrewInSK , Thanks for sharing your picture. We have not forgotten to ship your battery order. It is just that we had a...
