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

    The brake light and turn signals are a plus. I suggest that Zen mention this in the above list of specifications.

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

    Thanks! The bike is very nice looking and has many desirable features. Is the rear light hardwired and does it function as a brake light? When would the 2025 model ship to customers?

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

    I am also wondering what motor is now supplied with the E-14 version of the Zen Photon Ultra and what are the exact specifications of the latest model, including weight. I'm guessing that the E-14 version has the updated frame and colors with thicker aluminum and gusset to minimize flex. I...

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

    I just looked at the specs on Zen's website. Your attention to detail, component selection is impressive. The new M620, Rohloff E-14 and battery set this bike apart. I was wondering what size are the front and rear cogs? I ask because a purchaser on this forum changed the cogs on the Zen...

    Is it possble to covert 26x4 to 3 onch tire and rim combo

    The unknowns and cost lead me to think that putting $ towards a bike that already has smaller tire size makes better sense.

    Is it possble to covert 26x4 to 3 onch tire and rim combo

    I also thought about converting the Juiced Ripcurrent S 26x4 to a wheel sized for 2.8 to 3.0 tires. I called a LBS with that question and the mechanic said it was a matter of finding a rim that could accommodate the fat hub (spoke angle issue). I suggested a 29 in wheel (see post above) to...

    Ultra Chainring Swap?

    I installed the Wolf Tooth 52t 130BCD chainring on the outside of the spider and moved the chainring guart to the inside so I could reuse the existing bolts and also to align the chain better with 6-7 cogs where I will spend most of the time cruising. I already like the lower cadence. By...

    Ultra Chainring Swap?

    Thanks theemartymac, good stuff. This is exactly what I needed to make a decision about which chainring size and where to mount it for desired alignment and cruising gears. I don't see myself using the larger cogs often since most rides here are fairly flat. I will start with the outside...

    Ultra Chainring Swap?

    Does that fit the Ultra? I don't see the 130bcd in the description for the BBSHD there. Am I overlooking that information or is it assumed for the BBSHD? I am not familiar enough to know what fits various motors. They are out of stock right now. If someone has experience with another...

    Ultra Chainring Swap?

    I just got a Rize RX (non fatbike) and feel like I'm running out of gears with the stock 44 tooth chainring at higher speeds. I like the stock version because it has a ring to keep the chain from falling off the outside. I have searched for something in 50 or 52 tooth narrow wide. I had...
