    A Wish list for bafangs next mid drive system please share your thoughts

    I'd like to see a system that supports a front derailer
    Also
    More powwwweeerrrrrrrr!!!!! to quote a full faced helmet wearing speed freak.

    I am totally happy with one front chainring, it's the whole reason the Eclipse can have huge long teeth for super positive engagement.
    42 front 11-36 rear lets me climb almost anything, and still go just over 30mph on the road.
    The ability to run higher volts/amps is the only improvement I could imagine asking for.
    IMHO the BBSHD is near perfect.

      I am going for 11-42t rear to get a wider 1x10 gear range with more teeth on the front for speed. With 42 on the rear I should have as low a gear as you get with 36 but with 48t on the front. Just need a 48t Luna Eclipse to dump the 46t the BBSHD came with. Also need the higher amps you mentioned or 48t won't gain much speed do to excessive load.

    Thought provoking topic.....

    Real torque-reactive PAS with variable assist from mild to wild would be a very nice option to have.

    You should be able to set the wheel diameter to any size, not just a few presets!! :mad: Easy improvement.

    If the nylon gear could be available in a tougher composite material, yet still be quiet, that would be great, especially with respect to hot rodding it.
    Fabrication is fun! Build something today. Show someone. Let them help. Inspire and share. Spread the desire.

      I would like to see an aftermarket 40 amp controller. Inexpensive performance upgrade for BBSHD owners

        True torque sensing PAS instead of 9 steps of cruise control. States are moving to make ebikes the legal equivalent of pushbikes, but not if they have throttles......

          A system that has a lower pedaling cadence so it is easier to pedal along.

            Cadence can be reduced with programming, if PAS 1 is not low enough for you. I reduced my cadence settings for all except PAS9.

            Lower gearing within the drive, like 30:1 instead of the current 20:1, would be a way to make lower cadences more useful , powerful, and efficient. But, the small package and near silent operation are key advantages for the BBSHD. I would not want lower gearing if it meant making it big and loud.

          I'd like to see some changes in the display...
          An actual voltmeter, instead of the bar icon.
          Bring back the power display (watts)
          Have the 'power on' default to 0-PAS.
          It would also be nice to have a reading of the controller temperature as well.
          I agree that it would be nice to set the actual wheel circumference, instead of presets

            It would be nice to order the BBSHD to use a smartphone for display option. GPS Google maps and speed. A volt and amp meter built in would be nice (the bbshd controller must measure amperage if it limits it anyway), then could calculate Wh/mi and Wh used. Would be a much cleaner installation I think as well. Maybe even Bluetooth connectivity to handlebars with gyroscope/accelerometer brake sensing. Lot's of power to leverage there. A 3 year old or even older i,f it isn't already broken, smartphone has all that is needed functionality wise.
            I'm not complaining though, like others have said, it is nearly perfect for me. More tech is more crap to go wrong. Other than for programming the display is not necessary to me with the 52V battery and full throttle voltage sag I often see. A wattmeter and GPS on wrist is more useful for day-to-day commute.

              Ask Bafang to change the software to allow us to set our battery voltage like our tire size, that way the display gage would be accurate enough for most of us.

                If 52v was part of the programming, and higher amps were a selectable option, then the BBSHD would be rated for upwards of 2000w.
                So I guess the magic would be a firmware ROM flash. That's way over my head... But it can't be as tough to crack as IOS 9 passlock security.
                And within a few weeks the FBI found somebody to do that. LoL

                  The Bafang system is a lot closer to an Arduino than an iPhone. I think a fully Arduino solution would be easily done by someone with the time.. Im currently building an Arduino based charger with Bluetooth and a 7" touchscreen just as a hobby project.

                Better chainline, dual chainring or 2 speed transmission, voltmeter, watts consumed, automatic power cut off when shifting, 40 amp controller with temperature protection and NO PLASTIC GEARS

                  Well, a chainline which is better for some builds would be worse for others. So, it's hard to deliver 'better'. More options for sprocket offset would be nice, though. Spacers, and larger sprockets with less than the max possible offset.

                  In my case the BBSHD has too much inward offset (stock sprocket) but Mini 30 is fine. I plan to take a lathe to my Luna Eclipse when I get it, to reduce the offset as much as I can, and I still might need a spacer under the chainring.

                  If what you need is MORE inward offset, that would require repackaging the controller part of the housing further inboard/left, and probably reducing width of the gears or moving the motor, too. So, that would be a pretty major redesign.

                Torque-sensing pedal assist would be the core upgrade I'd want to see. Everything else is relatively minor and peripheral to the BBSHD's core functionality.

                Other than that:
                - Fully programmable wheel sizes in the display
                - A micro-display that is little more than up/down/select buttons and an LCD showing the current PAS level and an ebrake indicator, for people who have something like a Cycle Analyst or Batt-Man for a display
                - USB-programmable displays (making the previous two ideas easier to use)

                That's what immediately comes to mind. I don't think the BBSHD particularly needs more power off-the-shelf; 1000W seems like a good number, and it being conservatively rated makes it pretty bulletproof at rated power levels.

                  Good stuff. Karl Gesslein has a similar list on his blog that you might find interesting: http://electricbike-blog.com/2015/09...ve-bbsxx-kits/

                  All of the chinese displays and controllers that support PAS have the cadence. Why can't any of them including Bafang display it? Add that to the wish list.

                    Amp hours used and torque sensing.

                      Agreed, two major factors for me.
