Bbshd failures and troubleshooting

Does the display stay on and just says 0%? If the display goes off I would say its a connection issue. If the display stays on then it may be something in the controller.

I have a bbshd 1000watt mid drive with a 52volt battery.
today I went for a solid ride. I had 90% battery left and out of nowhere it dropped to 0%.... I’ll unplug the battery clean some stuff up, plug it back in then it reads 90% again. Doesn’t matter if I’m 1-9 as soon as I touch the throttle or pedal it’ll cut back out to 0% and won’t do anything.
I took a voltage measurement of the battery and it’s sitting at 53.92volts.
any idea if my battery is shot?
sensors done?
poor power connection?

It seems to happen as the crank arm passes the chainstay. Is it possibly touching that?
A loose crank arm could click like that, too. Make sure the center bolts are TIGHHT.
It almost sounded like the motor was turning when the pedals were, but that shouldn't happen. It's easy to spin the crank with motor off and wheel lifted, right? Should be only a little resistance.

Hi everyone, can anyone here please help me?
my BBSHD is clicking once per revolution when pedalling

Thank you.

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.Last edited by Retrorockit; 07-01-2019, 08:22 AM.

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.Last edited by joebreeze; 06-17-2019, 08:38 PM.

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.
