    52V and 72V Battery Chargers

    I've got two e-bike battery chargers available for sale along with a smart monitor. A 52V battery system charger (charges up to 58.8V which is a 52V battery at 100% charge) which charges at a rate of 3A and has a smart selector for the charge level you want (80%, 90%, or 100%) which can...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    This thread hasn't died out, it's been running fairly actively since it started back in July of '22. It's just not necessarily a response-in-a-day kind of thread. Regarding your first post above, what is your question/problem/concern?

    Electrifying a cargo bike - Mid drive or Hub?

    Totally true, just way more manual management than I want. My motor just helps me get to ~85 rpm cadence and helps me stay there if it slows down (either due to up-shifting or starting to go up a hill) Totally fair — yeah I wish there was a version of the BBS motors that had the power (actual...

    Electrifying a cargo bike - Mid drive or Hub?

    Yeah you can get away with that with the BBS02 since it's lower-power than the BBSHD, but that still essentially means you've just found the crank / gear ratio that you can still pedal with while the motor is at max power... meaning the motor is running at max power all the time. I strongly...

    Electrifying a cargo bike - Mid drive or Hub?

    Yeah, this is what I meant — plugging in to the motor's controller firmware and configuring various parameters to meet your specific desires. A motor tailored very specifically to your needs rather than the general public's. You do still want to figure out the right gear ratios for your given...

    Electrifying a cargo bike - Mid drive or Hub?

    FWIW my total rig weight when it's just me commuting to work is likely ~350lbs. Cruising speed is also 12-20, though I sometimes get closer to 23-24 when I have to ride in the road / cars. I got a very large capacity battery so my range may be between 70-100 miles, though I've never tested it...

    Electrifying a cargo bike - Mid drive or Hub?

    That's interesting. I'd love to ask about your programming and riding style. As the owner of a BBSHD cargo bike that routinely carts my large self, my wife, and all kind of other stuff on it around our town, I programmed mine quite specifically and haven't had any chain problems at all 😁 As...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    I don't actually run the open source firmware myself, but I understand it (and the stock firmware) pretty well

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Max cadence is all about how fast the motor is spinning. It also technically lowers as your battery depletes... but the idea is that on a full 52V battery (so 58.8V), with no resistance, the BBSHD (after reduction-gear) will spin the crank somewhere around 150 to 160 rpm. So when you set a max...

    K1 Flash - Simple firmware update for Bafang CAN motors. Speed limit for all CAN motors. Power adjustment settings (M510, M820, M560) and Calibration

    Interesting! I haven't seen a product like this yet, could be a huge deal for CANBUS Bafang systems. Don't have one myself but would love to see this thing in action!

    *SOLD!!!* Custom Build: Trek 69er, BBSHD, Rohloff, Magura MT5e, Rock Shox...

    Neat build and love the parts selection. A BBSHD with a single-speed chain line and a Rohloff transmission sounds like a great time. Good luck with your sale!

    Surly E•D•LHT - Touring eBike Build with BBSHD!

    Wow, so glad to have discovered this thread. What a cool bike, cool build, cool thread, cool battery, and cool story! SO neat! Is there a 2023 update, @Jaded? I'll be the first to say, if it ain't broke, don't fix it... but as I've happy jumped into the world of BBSHD programming over the last...

    Is there much market for a used BBSHD with very large 52v EM3EV triangle pack?

    Roger that. Well if you end up selling, DM me!

    BBS02 vs BBSHD - how much can you alter programming also

    I had the 500C and didn't ever experience issues seeing it, but as always, YMMV!

    BBS02 vs BBSHD - how much can you alter programming also

    Yeah, pretty much! Nice 😁 Understood on the display front. Yeah, I've never even seen that one 😅 and technically anybody can build a UART compatible display but YMMV on how configurable it is. I believe wheel size is totally a concern of the display alone — I believe the display only gets data...

    BBS02 vs BBSHD - how much can you alter programming also

    I agree with this for sure. I've asked the EggRider devs if they can add cadence to the screen — but in the meantime I do often ride with my Garmin running and cadence showing there (cheap, external cadence sensor on crank) It's tough to explain over text but while I spin with the motor...

    BBS02 vs BBSHD - how much can you alter programming also

    Oh and for what it's worth, to the question of range (one of your original major questions), I have a 52V 21Ah battery on my giant cargo bike (26x2.4 tires), I ride extremely upright (like a sail in the wind), my total rig weight is 350-400lbs at any given time, and my typical riding speed is...

    BBS02 vs BBSHD - how much can you alter programming also

    No, this is a great point, a good concern, and a well-eyed question! All brushless DC motors reach their highest point of efficiency (least heat created per watt generated) in the upper reaches of their maximum RPM — usually above 80%. That's definitely true. But how much wattage you're asking...

    48v Adjustable (97% 90% 80% and storage charge) (1AMP to 3.9AMP) Fanless waterproof ebike charger £50 Probably the best quality charger for the price

    Is this a single charger for sale or are you making these? Love the MeanWell stuff, would be interested in the 52V charger version!
