Hello,
this is my first post so please be gentle.
Please excuse if this is in the wrong sub-forum, I wasn't entirely sure where to post this thread.
I've been wanting a fat bike for quite a while but my knees are preventing me from riding one with a large Q-factor (QF).
Having test driven a Rocky Mountain Suzy Q with a QF of 203mm that didn't cause knee pain and Bosch Fat bike with a QF of 230+mm which gave me knee pain after 15mins of just easy pedaling, I can narrow down the acceptable QF for me to around 200mm and under.
It is possible to fit a 4.6" tire in the rear while having a 183mm QF with a derailleur gear system as demonstrated by the Otso Voytek so I am wondering if there are any full suspension fat bike frame designs that come close to this. Besides the Voytek there are many custom hard tails with a "horse shoe" style chainstay that "wrap" around the bulging tire that also allow for narrow QFs like the Travers Fat Bastard.
The Frey and M2S designs seem to be the most appealing over-all, but I can't find the QF for any of those frame designs, based on the photos from the bikes I am afraid neither the the M2S and especially the Frey have a small QF.
The M2S Ultra frame looks to be narrower (4" only) and maybe one could get down to a reasonable QF with narrower cranks than the standard ones?!
Can anyone comment on this? Could one order a custom rear triangle that allows for a smaller QF? I assume that it won't be too easy to make a narrower one without re-engineering half of the bike.
Also, how is the torque sensor on the new Bafang motors? Can the Bafang be programmed to behave similar to a Brose motor?
Let me list the frame designs I have found, leaving aside the QF, I hope this collection might be useful for other forum members who are looking for a full suspension fat bike with a Bafang mid drive.
There may be more but it is hard to determine from the crappy photos on Alibaba if it is the same design or just a very similar one. For example the M2S Ultra und Kush seem to be different frames.
Asian brands:
Western brands:
If you have any other frame designs that I missed, feel free to post them so they can be added to the list (regardless of the QF).
Thanks in advance for your replies as any input on this subject is appreciated!
