Nice looking bike……I can bet your bottom dollar the Yamaha motor would not have the power of the X1 ultra motor, Ive tried a few, including both the stock ultra and the X1 ultra, it’s day and night the difference, the X1 I find is very smooth and powerful, I don’t use the throttle, I wish you well.
The original thread wasn't solely about power, but in behavior and tunability.
OEM programming for Ultras for both UART and CAN variants are pretty awful, as they also were (possibly still are on the M600).
I didn't go with the VESC-based LudiV2 controller on my X2 for 'more power' but to ensure I had a proper amount of configuration and adjustability on what is otherwise a locked-down motor.
It's certainly possible even most of the Archon/Innotrace crowd are looking for the raw power, which is certainly higher than any OE M620), but some just want the bike to feel natural (or on the opposite spectrum as well) and 'the way they want it.'
Some of the callouts on Innotrace's responses while lacking are also true - FOC controllers inherently do have efficiency gains over the BLDC-type OE controllers.
Now, how much
smoother and/or natural feeling can an Innotrace Ultra be adjusted to compared to a UART decently configured (whether Smooth-tune or other), seems to still be in question... and the comments over the Yamaha feeling smoother could simply be down to the obviously lower max power outputs, or could have to do with internal non-adjustable programming. One of the things somewhat annoying me on Innotrace/Archon is it seems the programmability is fairly limited, and it
seems like the base behavior and options available haven't been updated in pretty much forever. This is one area where open-source
eventually holds a lot of promise... eventually as in AFAIK there is no open source Ultra controller, nor Ultra replacement controllers whose firmware is open source, at least <right now> AFAIK.
1-2 options (Bafang or Archon, otherwise pretty custom, e.g. Grin) is pretty much a monopoly within the market. I continue to hope Luna will launch their LudiV2/VESC controller for the Ultra motors to add another competitor into the ring, at which point the resultant 'feature wars' induced by real competition usually leads to benefit the consumers. Of course at the moment, it seems Innotrace's continued existence seems to be in question, but I'm still hoping for an eventual future where not only are third-party quality controllers (and corresponding applications) more of the norm, but they continue to drive competition to at least parity with, and then eventually surpass some of the 'big boys' like Bosch, Specialized, etc. Things like eMTB mode on Bosch, setting a distance/destination and having the controller monitor and adjust power output to ensure you make it home/there, better health/riding app integrations, and of course, configurability to suit the user, etc.
