So, unless I misunderstand the eggrider documentation, I can do the frey smooth tune settings through it.
So, if that is the case, why wouldn’t I want an eggrider? It effectively offers iOS based bafang parameter tuning.
I'm just trying to save you an expensive lesson. If you want an EggRider, go for it. If you spend some time looking at something besides the EggRider add copy, I think you're going to find it's WAY overrated. The DPC 18 can be set up for 5 or 9 PAS levels. 9 to my way of thinking, is overkill. There's very little difference between PAS 1 and PAS 2 for instance. Try it both ways to see what you think. It's done right through the display. The controller, internally, is set up for 9 levels. In "Eco" mode, it uses PAS levels 1,3,5,7, and 9. In performance mode it uses PAS levels 2,4,6,8, and 9. IMHO Eco vs. Performance is 100% marketing hype. Again, you're welcome to your own opinion....
DPC 18 not my favorite, but from a functional standpoint there's nothing wrong with it - especially if you like the auto on/off headlight. My preferred are the 750c for it's horizontal layout, and the 850c just 'cuz.
Have you sent Tom a PM asking about the software interface yet?
Is there any efficiency difference with those settings or is it just about smoothing the response?
I though rohloff with a belt can take much more abuse compared to derailleurs. I though you would chew through chains and have derailleur problems with that kind of power. What do you suggest using instead of rohloff?
IMHO, the biggest difference is regarding the torque sensing. It goes from practically non existent (turned off), to one of the nicest available. A bull in a china shop vs. one of the most refined programs available anywhere - one you able to easily tweak here and there to suit personal preferences.
As far as efficiency, yes. I think there's about a 10% increase on a charge. Again though, the smoothness is overwhelming. There's also the very wide pedal response. I find myself riding in PAS 2 on lazy afternoons using anywhere from less than 100 watts on the level to 400 or so when required to get up a hill (yes, I'm in a hilly area too). No change in PAS level, or what gear I'm in required. It's a torque monster, and I love being able to take advantage of that....with nothing but how hard I'm pushing on the pedal. -Al
Regarding the M620's ability to tear up chains, mine has 1500 miles on it and the wear tool shows plenty of life still left. The chain and sprocket killers are running around spending a lot of time on the 11t rear gear. There is not enough surface area on that 11t to handle/spread out the Ultra's torque on enough teeth! It's very hard on both the gear and the chain. Again, my opinion, is to stay off that gear. If you find yourself using/needing it frequently, consider going with 4 more teeth (or so) on your ring gear. All else being equal, that should allow you to match the speeds you had available with the 11t on the next bigger gear in your cluster. Then of course, there are those gorilla type riders who don't care about that big crunch every time they shift. Those guys are going to struggle too....
I have no expertise regarding the Rohloff. I have read where others, guys that sounded like they were well informed, have wondered about the Rohloff when matched up with something like the Ultra. With it's ability to be scaled back so easily, I think it might be a good idea to do that. Go with a conservative setting. Due diligence required.....
