    Gear shift indicator solutions

    The main reason for needing a rudimentary gear indicator is when switching/transitioning from pedalling only to using motor with throttle only especially on false flats with headwinds and crosswinds where smallest low gear should be at least 28t or 32t and then making sure it’s the right one...

    Gear shift indicator solutions

    How many are trying to implement any rudimentary gear shift indicators on shifters without gear readout to avoid starting mid-drives in too high of a gear. Was thinking about one based on reed switch and LED to indicate when I get close to 1:1 ratio while shifting for a few years now. Could be...

    BBSHD Controller Reliability

    There is never a full load on WOT in optimal gear such as 1:1. It keeps changing with inclines and wind before the current is staring to reduce again.

    What makes an e-bike good? (survey with prize)

    Seems like current and voltage sag graphical curves whic gives you a lot of information at a glance (increased safety) in real time aren't implemented too often without resoring to wiring clutter (dobious Chinese wattmeters with external shunts).

    Was there any ability to switch between street mode and sport mode on Cycle Analyst?

    Wasn't able to find any answers anywhere by doing quick search in this regard.

    Cycle Analyst - still solid choice?

    Currently using two Lemgo phone holder bags on handlebars which makes any kind of display less conspicuous (Cycle Analyst won’t fit inside compared to dpc18 display) Reluctant to upgrade the BBSHD to Phaserunner due to width of the Cycle Analyst. It’s made to be positioned in the centre which...

    Cycle Analyst - still solid choice?

    I’m using the phone for navigation.

    Cycle Analyst - still solid choice?

    Looks like nobody seems to complain about Cycle Analyst being too wide which makes it impossible to put it next to a phone on a narrow sweptback handlebars with a headlight in the middle.

    Torque sensor or not?

    I haven't been able to find any list with brands comparing the torque sensor response in subjective or objective terms so far since there aren't any testing stations available anywhere helping you to draw your own conclusion. Whenever I read about anyone mentioning torque sensors they are always...

    Torque sensor or not?

    The mushy feeling was with TSDZ2. Since it felt like a normal bike when the motor was off then the mushy feeling wasn't caused by mechanical problems but constant interplay between the motor and legs especially on hills caused by certain amount of motor delay. Since people said TSDZ2 feels no...

    Torque sensor or not?

    Torque sensors typically feel mushy when pedalling. Not sure if that can be considered natural. Cadence sensors feel like constant tailwind which motivates you to pedal harder as long as there is no ghost pedalling. Also using torque sensor results in need of motor assistance even on the flats...

    History of the Bafang BBSHD Over the Years

    Wasn’t it discontinued according to Captain Codswallop? Probably made a mistake by getting BBSHD instead of M635 which should have foc controller. Not sure if this could be a good upgrade alternative to ludicrous controller for those who don’t like unnecessary external controllers? I guess they...

    Scientific analysis of BBSHD! Motor characteristics, Winding pattern, ...

    Someone probably has done it already by now since this is considered to be such an old motor.

    Scientific analysis of BBSHD! Motor characteristics, Winding pattern, ...

    Looks like the BEMF showed in the BBSHD paper is more similar to the trapezoidal example provided by Texas Instruments. Hard to believe this might mean that staying with the stock controller might result in best efficiency and torque production compared to any low Rdson mosfet FOC controller...

    If you had $400.00 to spend?

    The torque sensor on TSDZ2 results in mushy feeling with the PAS on. Cadence sensor on BBSHD felt more like a constant tailwind at 50% RPM and 50% current to reduce ghost pedalling (still can feel hard pressure on the pedals as if pedalling without the motor compared to torque sensor).

    CYC PHOTON

    All I know that TSDZ2 on 1-3 PAS levels felt like it makes pedalling somewhat harder while level 4 felt like motor takes over and there is no pedalling resistance especially in granny gears when climbing. It was hard to decide how much should I exert myself before 17% hills otherwise the motor...

    CYC PHOTON

    Weren't torque sensors more intended for offroad climbing trough huge rocks and such in general? Cadence sensors might also be important for roadies due to ability to help keeping constant pedalling RPM while not losing momentum on hills compared to torque sensors which respond to inherently...

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

    Is it normal for PAS to slowly creep up after about 30 seconds when riding at 39 km/h in 40t:13t gear (motor programmed to have maximum power and cadence around 50% only in order to minimize ghost pedalling)? It results in loss of speed when shifting gears. When riding slowly it doesn't seem...

    How To, 50A BBSHD Controller Mod

    Talking about stock controller and 52V battery. Since hammering the throttle on a 17% hill with gear that low results in wheelies then then the peak load on the nylon gear resulting in damage might be reduced since it does slightly less work by lifting the front of the bike up compared to...

    How To, 50A BBSHD Controller Mod

    What about hammering the throttle on a 17% hill with 130kg system weight in 40t:51t gear with 7°C ambient temperature and cold motor?

    CYC PHOTON

    Weren't there rare reports about open source firmware improvements regarding to throttle smoothness on BBS02? Seems like there isn't any snapping sound coming from freehub and it's easier to accelerate very gently according to personal experience with BBSHD using open source firmware.

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

    Does this open source firmware work with Zeekpowa display? https://zeekpowa.com/collections/ebike-displays/products/e-bike-display-g1-for-bafang-bbs01b-bbs02b-bbshd-motor-electric-bike

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

    Is it possible to send Wattage or current value to "calories" field since the DPC-18 doesn't show exact current value in Amps but only green bar which is hard to discern? Probably will have no other choice but to get 850c display since T1 display isn't supported as far as I understand.

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

    Was asking this since there wasn't anything like that with stock firmware (also limited to 40 km/h). Another concern is 4 second long rattling sound when realising the throttle while riding (normally heard with the motor unloaded for shorter period of time (also heard in videos posted by other...
