    Bafang Ultra loss of pedal assist functionality

    Have you double-checked that the speedometer magnet is still reading consistently? Cadence sensor too... (Speedo sensor, is easier to check though!) Any of the three (including the torque sensor), could present an issue similar to what you describe... If it turned out to be a display issue...

    Bafang Ultra Alternative Settings For Basic, Pedal Assist & Throttle Handle..

    Note that Base Voltage should NEVER be left at 0 mV. Bafang ships these motor controllers with the torque sensing uncalibrated. The minimum value, at zero pedal force, which these torque sensors can output, is around 732 milliVolts. Anything below 730 mV in the Base Voltage field, is wrong...

    Bafang Ultra Alternative Settings For Basic, Pedal Assist & Throttle Handle..

    Let's see... Frey AM1000 v5 (XL frame), 48V 21Ah battery, 27.5×2.8" Maxxis Rekon+ tires, 40-tooth front chainring, 11-to-42-tooth 11-speed rear cassette. Used mostly on urban streets\lanes\paths, so far; though it's been very confident through the rough, what little it's seen yet! Climbs like a...

    The top-tube looks like it rolled out of bed wrong one morning, but I like the AWD concept, & wonder about electronic traction control?

    Reention Dorado 48V 25Ah 29Ah&36V 30Ah (505L) Replacement Battery for eBikes Surface 604,NCM,Rize,Magnum,Aventon

    We've got at least 2.5 centimeters of clearance, at the closest point above our 48V 21Ah Dorado pack (Frey AM1000 v5 XL frame)... Is there any case even larger than the 48V 25Ah 21700 pack, which would fit the same connector?

    Watt Wagon direct competitors?

    You're quite right. Not sure what I was even thinking of. 🤦 Probably something ludicrous. Hopefully they start shipping X1 controllers on CANBus, or confirm ability to swap out stock CANBus controllers for UART X1s, soon!? (And someone with eyes on the controllers, does confirm that these...

    Well, that's very different from just a direct throttle, but I think you describe exactly what I'd like to see, too!? Regular current-based throttle? Yes please, always! But more similar to what you described, a slider (which stays put) to adjust the level of assistance supplied in response...

    Sorry for the long post, everyone; that one felt like it was worth unpacking piece by piece, to explain why TLDR: CANBus = bad news for users, bad news for 3rd party maintenance, & bad news for feature development. Why? Vendor lock-in. Parts "secured" against refurbishment, exchange...

    Yep: Vendor lock-in, & lower wiring harness cost for complex vehicles with many interconnected electronic modules. Kinda proving my point for me, here: An ebike has none of this multipart complexity. Cluster, accessories & security, are all provided by the display, & there _is_ no...

    I'm not recommending a touchscreen interface, I'm merely pointing out that connecting a touchscreen display & cockpit-controls system, to a UART motor-controller, for configuration & controls, is exactly as easy as connecting any other display & cockpit-controls system. Display &...

    Untrue. The UART protocol involved is simple, functional, & shared across many component manufacturers. What redundancy? What adaptability? Untrue. The latter are display features having nothing to do with the motor-controller; & anyway the motor-controller is readily programmable & controlled...

    The new AM1000 V6

    💯 Frey has been shipping both UART & CANBus Ultras for a hot minute now (as well as a limited number with 'custom' 60V controller), so I wouldn't be surprised if they eventually follow a strategy similar to Luna's, of fitting aftermarket UART controllers to Bafang's g510 motor cores... 🤞

    Frey AM1000 motor fail

    Makes sense that it may've been done to avoid excess wear. ¿... Especially since some seem to receive their controllers with throttle Mode set to Speed, which makes it respond relative to the difference between one's speed, & throttle position (bigger difference, more throttle). !!! ? That...

    Watt Wagon direct competitors?

    And yeah, I'm increasingly burning with curiosity to know, who produced the "custom" 60V@30A UART Ultra controllers for Frey, & who produces the stock UART & CANBus Ultra controllers for Bafang?!? From what I've seen so far, it really doesn't add up as in-house work, unless one branch of Bafang...

    Watt Wagon direct competitors?

    Aye, which won't fit inside the case... I wonder whether whatever 60V@30A controller Frey uses on the Beast, fits inside the case either!? (They do, & it does! Beast's is a stock board with (original design spec) 100 V capacitors, swapped in?) Well no, I'm assuming Bafang would want their most...

    Watt Wagon direct competitors?

    I want to know what Voltage range it can handle... 54 too low? 72 too high? With aftermarket controllers, Bafang's m620 motor, reputedly handles 70 Volts quite happily? With slightly more Newton-meters of torque per Watt, & less heat buildup per Watt, than at 48 Volts, 60 Volts sounds reeeeally...

    Regarding the BESST tool: Where does Bafang get their controllers? (ASI?) Extreme cynicism incoming! I have seen no evidence to date that Bafang has a clue about the controllers in their motors: Their "default config" is essentially not configured (dangerously so!), & some of the controller...

    Well, touchscreen & app support, are largely independent of the motor+controller itself: The display & controls use a predefined set of signals for all of the controller's supported functions. Theoretically any device capable of sending a few very basic signals, can command such a motor...

    Which should be prime candidates for a controller swap... 🤔 Dangit, for the third time today I wonder exactly what controller is in the Beast, anyway?!? (Edit: Am I to suppose that's probably CAN-Bus too? Maybe I should be cultivating contact with someone at PA-Transformers or ASI?)
