    Bafang Ultra Motor (M620) Longevity - How Long Should They Last?

    Aside from replacing the factory grease with SHC-100, the first necessary servicing for me is after 17000km roughly. Thought it was my clutch going, but it's in decent shape. Issue is the Needle bearing shown above is starting to bind and bunch up. Was able to give it a deep clean and manually...

    What Do You Wear Over Your Eyes When Biking At Night (Especially During Cold Weather)?

    i have two things i use: Ski goggles for a regular helmet. I use these for warmer weather or quick trips For long cold or wet commutes, i have an ILM offroad motorcycle helmet that the visor can come up. It will fog up since its meant for highspeeds, so i often have it partially open. Your...

    m620 reduced power issue

    i did set it to 30, and its been a huge improvement. I reduced the Current Assist % to max out at at 60% essentially doing the same thing i was after. With the BBSHD their power save threshold was much much lower, so never had issues using the current limit this way. Dont think it was...

    m620 reduced power issue

    Here's a pic attatched of the bms after the ride, I don't approach the low voltage cut off of the battery even with voltage sag under load. As to why the range seems low for its capacity, the pack is down to 80% of it's rated capacity, still not degraded near enough to retire it. My settings...

    m620 reduced power issue

    First off, thank you for your guide, i reference it a lot when finetuning my torque profiles and appreciate the thoroughness! still not done my tuning, but getting there :) As for this Power save mode, i just gave it a name since theres so little information out there about this characteristic...

    m620 reduced power issue

    After multiple days of testing i've found the Power Save mode is 43% of your programmed current limit. (verified in Road Mode at 30%, Offroad still enters powersave, haven't yet verified at what percent) Default (and maximum) Current limit is 30A, so you will get maximum current you will get is...

    m620 reduced power issue

    Last weekend i assembled a new ebike with a seroxat frame and a UART m620 motor. After several rides i've been encountering the power output limiting once my battery reaches around 47V (~30%). Once i hit this wall, my max power output is about 350 Watts, no matter the assist or throttle input...

    Ultra Tuning: Master Thread -- Start Here!

    this was indeed the problem for me, i just raised the value for mincur in spd0 and spd20 until it worked since i didn't see this. Now i ammended the settings to adjust the keep current % for these two columns and its all good!

    Ultra Tuning: Decoding the Voltage Section of Torque Tab

    Just for reference, at the moment this screen doesn't display correct data on the current app/firmware. Eggrider devs have not finished on it yet. Believe everyone should see 1217 mV and no change with pressure.
