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?"
Unfortunately, the m620 doesn't have a brake sensorThe gear shift sensor throttle cut on my BBS02 is too short. I now engage slightly my front brake to cut the motor until the gear change is finished. Work very well for me.
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.
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).Unfortunately, the m620 doesn't have a brake sensor![]()
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 presentVery good info to know for when my Z1 comes in. Thank you.
@Tom@WashDC do you know if the UART tuned up M620 from Luna comes w/ front and rear light inputs? I see on greenbikekit it's an option I can add and was hoping the Z1 I ordered would come w/ the ability to add them.
There is a brake sensor plug.Unfortunately, the m620 doesn't have a brake sensor![]()

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?).
