I know we all have different riding styles and preferences, but I fell into a funny trap this year with the purchase of my sixth BBS02. Namely, I have been unable to find any solution or settings that allow pedaling along with normal throttle usage. At full throttle you can also pedal, but at anything less than full throttle while pedaling there is no throttle response. Stated another way, if you are pedaling in any PAS level, 0 through 9, and attempt to use the throttle there is no throttle response until you get to full throttle. If you aren't pedaling or quit pedaling then there is normal throttle response.
Since I had purchased two of the new versions ,BBS02B, this year, and the one that did not have a dedicated gear sensor worked the same as my previous BBS02s, whereas the one with a dedicated gear sensor had the abnormal pedal/throttle issue, I figured the problem was associated with the dedicated gear sensor.
But now, after several weeks of research including several email exchanges with the vendor, the purchase and use of a controller programming cable, and the purchase and installation of a new controller I am back to square one on why these new BBS02 controllers behave this way, but this does not appear to be limited to the controllers that have the dedicated gear sensor:
Controller on first BBS02B with date/serial 1609270057 and no gear sensor has no pedal/throttle issue;
Controller on second BBS02B with date/serial 1705310074 and a dedicated gear sensor has the pedal/throttle issue; and
Replacement controller installed on second BBS02B with date/serial 1709140337 and no gear sensor has the pedal/throttle issue.
Anyway, even though I usually just pedal with no assist or a fairly low assist I'm not affected too adversely, but I miss being able to get a boost from the throttle unless I also quit pedaling.
My reason for this post is to inform current or perspective purchasers of the new BBS02B to be aware of this potential issue. If anyone can provide more information please do so. I expect the answer may lay in a controller setting we aren't yet aware of since all three of these controllers are firmware version 2.0.1.1.
