Ravi, my suggestions for specifics to talk with Bafang about are: 1) Understanding what the Pedal tab settings do for the Ultra, if anything. Most seem to have no effect and their naming implies an overlap with similar fields in the Torque Tab that would appear to provide more control per bike...

It's still Ravi's call. The double-fake-magnet method provides a better on pavement riding experience than the stock Bafang programming model can provide while still giving the rider an accurate bike speed readout on his display. Hardly "irresponsible." I suspect the gating question for Ravi is...

Well, that's up to Ravi, obviously. I did say it was "perhaps outlandish." Stop trying to make this personal. The facts are what they are. I've outlined a simple test procedure for anyone with an Ultra motor to verify my statements as to how the Ultra behaves with changes in the Torque Tab. As...

This looks like a great bike. I'm going to assume, given general layout and tires, that's it's intended for paved road/trail or easy/wide packed dirt trail use. Then, if it is indeed a Uart Ultra that can be tuned: 1) My first, perhaps outlandish, suggestion would be to employ my...

The EX1 is an 8-speed chain: “SRAM EX1 chain Marginally wider but much more robust, the SRAM EX1 chain now features rounded edges to increase shifting precision and boost durability. In event of a defect, the drivetrain can be run with a SRAM 10-speed chain if needed.”...

Yeah, looks like the rejiggering of the forums caused all those links to break. Should be fixed now, thanks.

I’m late to this thread, but since you have a Shimano Deore derailleur you should follow Shimano instructions, not SRAM. Some of the wide range SRAM derailleurs might have different chain length requirements.

I'm sure leaving my posted experiences out was an unintentional omission on your part. What strikes me as non-ignorable to this day is that after several years (dating back to 2017) and several"programming guides" being posted on the interwebs and here on EBR's forums, it wasn't until last...

Great to see people customizing settings for what they want - it's why I was hesitant to post my own "quick start" settings in the first place. That said, I do have a couple observations, which may or may not be relevant to people: 1) Gionnirocket's Delta Voltage table settings are linear from...

I would assume he's running the EggRider phone app, so there isn't any right clicking or administrator rights. Have you tried asking in the EggRider Facebook group? That's where they handle support.

The serial number and 48v controller indicate to me that it's a 750watt. The sticker for the bicycle was probably just to get around import/use restrictions. A lot of that going around.

Instead of using "Display Command" for "Designated Assist," why not use level 9, which is set to 100% current? You can always modulate the throttle to get less output if you don't need it all.

On a 52V battery, full charge is 58.8volts and 50volts would be just under 50%. That's only 17miles of "normal"? riding to drain half the battery. It's likely the BMS has its own low voltage cut-off. That said, 47v is too low for a 52v pack. EDIT: I meant high, sorry. Cut off should be around...

Can you discuss more about "Power Save mode?" I've not heard that term used with the Ultra motor/controller before. When I saw your first post I was thinking that your 18A Max Current was the issue and that I've not seen an Ultra configured from the factory with less than 30 as its Max Current...

I would agree with that, but I also think your hyperbolic Delta Voltage table is also contributing to that early power feel. To explain a bit about how it works (roughly speaking): 1) When you pedal, the torque sensor returns a Voltage in proportion to how much force you're putting on the...

That's SPD60 territory. Looks like your SPDxx table is setup for the Frey tune, which I don't think is an optimal tune. In particular, the Full(kg) starting high and linearly decreasing isn't based on any real world data or even, IMO, desired behavior. You need all the power you can muster to...

That's quite low, as the full 60kg of pressure should output over 3200mV. What were your SPDxx table settings? What was your pedal crank cadence? What was your bike speed? Maybe try setting Full(kg) to some lower value, like 30, for the SPDxx columns corresponding to your bike speed up the hill.

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...

You don't want my Quick-Start settings, which I setup for my riding style, which is that I want to get the motor to assist me as I pedal harder. You basically want a throttle to get you up the hill. That's not a judgement, btw, just an observation. The first thing I'd ask/suggest is at what...
