I thought the Luna has a gear sensor under the battery. I have never needed one. Just ride like you have a manual transmission.
For curiosity sake I sent an email to Frey... Here's their response.Speaking to "Kathy" at Frey Bike, she said 3 days to ship from CA warehouse. I ordered it on Friday. Should be here by next week. Yes, I have a friend that has a CANBUS Sondors Rockstar. He installed a UART controller and display. The controller assembly came pre-installed as one piece mounted with the side motor casing. He did need a new wiring harness and display.
Sweet! I saw that they had the programming cable on their site for sale so I figured as much.For curiosity sake I sent an email to Frey... Here's their response.
"Savannah ULTRA CC is equipped M620 1000W mid-drive motor, and it is UART protocol only.
Unlike the CAN protocol, most riders prefer the UART protocol, which is easier to operate and reset.
May I know which protocol you prefer? UART or CAN protocol?"
Very good info to know for when my Z1 comes in. Thank you.Good point Al. I did drop my delay stop or decay whichever it was, down to zero on both bikes so the power would shut off as soon as I stopped pedaling. UART protocol on both controllers.
As I recall there are connections for front/rear lights (no brake activated light). I've taken the motor out a few times and the light connections are present
This suggests otherwise. That is the brake sensors connect via the EB BUS cable loom. My Frey Beast cuts power when I apply the brakes (Magura MT5e brakes).
No, the Bafang Ultra motor is normally set for at least some run after pedaling stops. The KeepCur(%) in the SPDxx table on the Torque Page is normally what people associate with this behavior. There is also a KeepCurrent(%) on the Pedal Page, but that's most likely an unused left-over from Bafang extending the BBSxx software to handle the torque sensing Ultra. I think if you have zero overrun you'd have a jerky ride, maybe with the motor cutting out sometimes during normal pedaling.My Frey Beast is the same. I find that the motor still runs for a bit after stopping peddling, and it ignores the shift sensor during this overrun (perhaps I need to adjust something?).
