    Thanks paxtana! Yeah, all it was was that the connected brake lever was not fully engaged, thus triggering the brake light. Now i know what the light is and what to do if it comes on :)

    Installing a kickstand or center stand can pinch the wires also.

    (!) means either the ebrakes are engaged or the ebrake wires are shorting against themselves, or the gearsensor wire is engaged and/or shorting against itself.

    " (!) This is comes up when the ebrakes are engaged. It may also come up when using the gearsensor, or if the ebrake/gearsensor plug is being short-circuited. Unplug the brakes, unplug the gearsensor, check the pins on the plugs to make sure there's nothing being shorted. Often this can happen just from the brakes being improperly installed."

    Hi, the DPC-18 display on my BBS03 motor is showing a red exclamation mark in a circle at the top right corner of the display and the motor is not delivering any assistance. Any idea what could be wrong. The motor performed perfectly with a 965 display on another bike and even worked on this bike with the DPC-18 display once, but now isn´t responding. I´d be grateful for any suggestions.

    Thank you for your help.

    You just described my problem and riding style exactly. Heavy rider, heavy, loaded bike and trying to start from dead stops with PAS. Looks like I'm ordering a new gear ring. I wish I had read this a few months ago.

    You are allowed throttle , you are 65.Throttles are illegal in NY , NJ

    I was very rough on my bbshd with my 1st bike, and my new build weighs around 90lbs plus my 190-200lbs. The only issue I have had was a snapped rotor gear that was determined to be defective and replaced under warranty. I do use throttle most the time to get going and will switch over to pedals once I'm around 5-10mph. Seems to work wonderfully with S/A 3 spd IGH.

    I use assist level 0 for much of my riding, and level 1 mostly. Level 2 for hills and headwinds. The throttle is for keeping up with cars at traffic lights, or when my 65 year old self needs to maintain 30MPH to keep from getting run over. My granny gears are only used when sharing a sidewalk with pedestrians and assist level 0. I wonder what percentage of riders find standing on the cranks in high gear useful? The aerodynamics are lousy and spinning makes more power. On a 40 mile ride I might use the throttle 4 times.
    The motor allows me to ride at speeds and distances that I couldn't do otherwise in any sort of comfort. I don't see how that makes me lazy.
    But if standing on the cranks and breaking parts makes you feel like Superman that's up to you.

    Call me old fashioned , but I like to use the pedals . Way more than 1% of riders want to ride normally by not using the lazy throttle (i'm not delivering food) and not granny gearing it at every traffic light or incline.

    I completely know what you are talking about mate , except I didn't have all that weight and my motor teeth broke also ?

    I weigh 190 lbs , and the bike is a normal FS MTB 10 SPEED. I had the thing out 1 day and as im a 'stand up off the seat' kind of rider I broke teeth off the clutch engaging gear.

    At first the forward slip feeling reminded me of a chain slip , so I adjusted the chain tension / derailleur alignment and went off , torquing the pedals hard to check the chain and WHAM CRACK SLIP . Later I realized what had happened , that I had broken the motor in 1 day.

    Suffice to say YOU CANNOT RIDE A BAFANG MID DRIVE LIKE A SINGLE SPEED . NO STANDING , OFF THE SEAT , HIGH GEAR (LOW MOTOR POWER)

    to quote Eric 2016 "The BBSHD is built like a tank" , a WW2 tank maybe.

    I wouldn't hold my breath waiting for Bafang to solve a problem that only applies to 1% of riders. Cost and weight could go up, and Bafang is pushing the envelope in both areas for most users. You didn't say what driveline you have but a lower 1st gear would seem to be the answer. Sturmey Archer makes a 3 speed IGH that's strong and accepts casettes. This can make up for the lack of a front derailer.

ID:	86100 Just wanted to share a problem that I encountered, its symptoms and solution. I have a BBSHD installed on my Gazelle cargo bike. The bike weighs about 80 lbs total, I'm 165, I often have groceries at about 20 lbs, a 9 year old passenger at 80 lbs, and we live in a very hilly area.

    I never installed the throttle, preferring the purity of a pedelec. In my situation, with the heavy loads and hills that I consistently encounter, the choice NOT to install the throttle was a mistake. Starting off on a hill requires a tremendous amount of force on the pedals to get the beast moving. After a complete crank rotation or so the pedal assist kicks in and we are off to the races. One day I was torquing the pedals hard to start on a hill and felt the pedals and crank snap! hard and then immediately catch once more. This alarming jarring scared the beans out of me but nothing seemed amiss afterwards. The end result was I often now experience under significant torque a SNAP! and the pedals sharply advance and catch once more.

    Thinking that I hurt the clutch I ordered a new one for $24ish, only to discover that it was actually the inner ring gear that the clutch engages! This inner gear has several teeth chipped in exactly the shape of the clutch "arms." I wasn't expecting that one. Unfortunately, the $38ish ring gear is on backorder so I will have to patiently wait. While investigating this problem inside the motor, I decided to make a jackass of myself by breaking the PAS magnet which has now disabled my pedal assist.

    Faced with no other choice I have installed my throttle while I wait for parts. This allows me to pedal and permits operation of the motor in an albeit hot rod manner. The important lesson I have since learned is that the throttle works wonderfully to start a heavy loaded bike moving from a stop up a hill. If I would have used that to start my bike moving, instead of relying upon heavily over-torquing my pedals, I would still be riding on my original parts today. Lesson learned.

    Now one could argue that the ring gear or the clutch should be strengthened to accommodate these forces. Sadly, I don't work for Bafang and these solutions are for future iterations of our beloved kits.

    Best,
    Stephen

    Replace the controller. Water damage is most likely the issue. Do not ride in heavy rain unless you've checked out the waterproofing guide and added dielectric grease.

    Good Day - the name is Brian. I have a BBSO2 750 B - its fitted to a regular hybrid type road.mtb. . It works really well and has transformed life for to some extent as I am partly paralysed from the waist down - but I can ride in a somewhat dodgy fashion which I really enjoy as I can only walk with the help of 2 crutches and even then very slowly and painfully . Our area is very hilly , even so I find that it has a max range of about 52km

    However I have a problem --

    2 weeks back I was riding in pouring rain and after some time the motor cut out . That is the PAS did not work , also the throttle was dead - everything else seemed normal. I had a local e bike shop look at it and they decided the controller was the problem . I have ordered one from Lunacycle and it will arrive hopefully if the SA post office does not lose it .

    After a few days sitting in the sun the bike came back to life ! I used it this morning - everything seemed normal - after about 8km or so it cut out again. After 5 minutes it worked again - this happened a few times .

    I think the thumb throttle and the lcd screen are ok . Could it be the controller . Has anyone else had something like this happen ?

    Any advice and opinions would be most welcome.
