What about the Rohloff oil leak, Ravi?
Not only is the a Rohloff a climbing beast with the Ultra... but the gearing allows you to ride these heavier bikes all about and up most hills with no assistance easily.Rohloff has a gear range of 526%, which is quite high and enables climbing very steep hills.
You can find the gear ratios here: https://www.rohloff.de/en/service/handbook/speedhub/technical-data
Most of what I've read leaks are from over filling or leaving the bike on its side.What about the Rohloff oil leak, Ravi?
when I purchased my ZEN, they were very careful about size. I thought I was a good candidate for the large at 5’9”, but ended up with the medium. You might give them a call If you are serious.
In that case, I'd prefer the larger frame size. Keeping the seat closer to the frame makes hopping on and off the saddle easier.I just looked at the geometry dimension specs for the Photon and all are identical for M and L except for the frame height—that doesn’t seem to really be two different frame “sizes”. What am I missing here other than larger maximum seat height on the large size? The other geometry is the same on both sizes.
As an Omega owner, I can report that the Zoom brakes are indeed spongy, unfortunately. It has not been a problem for me particularly, but I might replace them before it becomes a problem. It's my only complaint about the mighty Omega. I really like the specs on the Zen Photon though....and was not a fan of the Zoom used on the Omega vs the Zen choice.
Have you tried a lever bleed?In that case, I'd prefer the larger frame size. Keeping the seat closer to the frame makes hopping on and off the saddle easier.

Recognize that I am nit a ZEN expert, but I think th main difference is based on leg or inseam length. The seat and handlebar locations are tune able. I have bought and built maybe 30 bikes over the years and it seems thatbevery one of them needed tweaking. I am already planning on changing the ZEN when I get it because I tend to measure my rides in hours and 10s of miles and at my age comfort is king.
The walk assist on the omega is dangerous. When you engage it it takes off at 10 MPH. Really can't be used to go up a ramp to a bike rack or trailer.Thanks to all the input on this and another forum I am down to two very similar and excellent choices, I think. The prices are very similar. The Photon Pro has a better hub and a good front fork and a single long distant battery. The Omega has two batteries giving a bit more distance and the automatiq shifter. The Omega comes with a 4 year warranty while the Photon comes with a lifetime frame, 1 year electronics and 2 year battery warranty. I am really interested in any inputs from folks that are familiar with either of these bikes and any experiences in after purchase support.
The only time I tried Walk mode is when I first assembled the Omega, and it almost "walked" the bike and I through a wall. I haven't tried Walk mode on an e-bike yet that I found useful. It would come in handy on one of these hefty step-thru frames though. They are, at best, clumsy to carry. I have a few steps into my home and a very gradual or incremental "walk" or "step-up" mode would be helpful.The walk assist on the omega is dangerous. When you engage it it takes off at 10 MPH.

And you had the bike in the lowest gear?The walk assist on the omega is dangerous. When you engage it it takes off at 10 MPH. Really can't be used to go up a ramp to a bike rack or trailer.
I am still waiting for my Photon Ultra, while I was told by sales when I purchased it that I would receive it mid May that date is now moving towards June. I agree tat the walk mode is critical. it is especially useful when loading heavy bikes on the rack. The ebikes like the omega and photon are pretty heavy and a ramp becomes a necessity and walk mode makes it a lot easier to load.
