Yeah, first set was basically to move to known near-bulletproof hubs (DT350) and wanted to give the i40 rim width a try. The X2 wheelset seems decent if heavy overall, with a few people eventually wearing out the rear hubs. Have done some fairly unique long motorcycle trips over time, including 'dirt bike and a map' for a week in a foreign country, longer trips etc., plus have spent some time on tracks with my cars, so I'm all about 'ensured reliability' as much as possible. The Arc i40 wheelset was fine, just felt like building a wheelset and tried the i35s. Pretty much a toss-up but might pick the i40s again in the future.
You can send me a DM if you'd like. Might be up for selling the Arc i40/DT set.
I wouldn't consider the X2 a motorcycle replacement - the Z1 would be closer to that, although still not as both are speed limited realistically to ~30mph(x2)-~35mph(z1), while the Z1's much bigger Ultra motor does better with sustained heat/thermal loads so is more tolerant of riding by throttle. The X2 is great, as an 'assisted mountain bike' - but not a mc replacement.
Not sure on the Q in there last line - I have kept my Ludi controller firmware up to date. The speed sensor works fine, meaning it's reading and displaying MPH. If you meant cadence sensor, the LudiV2 primarily or possibly even solely is using the torque sensor for assistance algorithms. I know there was some discussion on 'blending' the cadence sensor as another input, but don't think that's the case on current firmware.
Depends - I've had a similar display on my BBHSD fat tire bike, and they're neat but I don't like the placement as it's problematic if you need to flip the bike upside down for maintenance, and in reality it's just not really needed. The OE display meanwhile is nicely tucked out of the way. I wouldn't mind one slightly larger, like a CAN version of the 500C. Meanwhile, some others love the 860c, so YMMV. I just don't spend a lot of time looking at it at all.
Yep, 160mm, from Miranda direct, who shipped amazingly quickly to the US.

Unsure if they can be bought elsewhere other than their web shop right now.
