Ребят, всем привет. Помогите, не знаю что делать. При включении мотора на экране 750с появляется ошибка Error 30H — велосипед ни на что не реагирует,ни на кручение педалей, ни на курок газа.
Всю проводку перепроверил, контроллер снимал, переподключал — там всё сухо. Единственное что мне помогает — краткое замыкание разъёма тормоза (мини короткое замыкание).
Также пробовал перепрошивать контроллер.

У меня такая херня появилась, когда я раз 20-30 тыркал перепрошивал, ибо разъем там шибко тугой, оказалось в дисплее чет оторвалось(. Проводка это скорей всего. У меня не работал дисплей, ну точнее включался, но ниче не показывало, пришлось даж выключить выключение в простое, и вполне себе доездил сезон. Думаю, у вас похожее что-то. Попробуйте подключить к компу, и включить опрос контроллера, и станет более менее ясно, в чем дело, у меня комп опрашивал, а вот дисплей — нифига.

Bafang BBSHd BBS03 Error 30H
Error 30 is a communication fault between Bafang components on the BBSHD & BBS02 kits. It is a common error and the usual culprit is a communication error between the display and the controller. The Bafang set up requires a display (961,963, 965, DCP10) to function properly and unfortunately this makes the system less reliable.
How to Fix Bafang BBSHD & BBS02 Error 30:
1. Check all the connections and make sure they are connected properly.
2. Move the connections around and check for any twists or bends in the wiring harness.
3. If it still shows error 30 then it could be a faulty component. Move onto the next section to test components.
How to Test Bafang BBSHD & BBS02 for a Faulty Component:
Check the following components:
- Display (most commonly at fault)
- Wiring (check the wiring loom for damage or crushed wires)
- Controller
- Speedo
These components are cross compatible with all Bafang mid drives (apart from the controller). If you have another BBSxx kit or know someone with one, you can interchange the display, controller or speedo to troubleshoot the faulty component(s). The only other way to fix error 30 is to try replacing the components one by one until the problem goes away.
Had bbs02b clutch problem, pedals turning but only motor works not anymore bicycle but a scooter, with a pedal throttle 
Then repair clutch was going to take 3-4 weeks from China.
Local, in Germany (quick shipment) online sellers were asking over 100e for clutch and tool to remove.
Since i am a bike courier, making over 500km per week, decided to take another bbs02b and also second motor with guarantee for 500e.
Second day second motor stopped working, error 30 and then error 21.
Catastrophe because some days okay but weeks to cycle with normal bike would be too much.
Got a 3rd as a desperation, to send second one back for refund.
Just after 3rd arrived, 20 minutes later found the problem causes for error 30 and 21.
Error 30 and 21 was because my middle double stander, cut the cables of Speed sensor and Gear sensor. Because i didn’t make the cabling very well,l when they exit from motor and follow their paths to the speed and gear sensors, they got loosened and double stander was smashing them during its opening. Happy to be found, and fixed.
3 days later, only error 30, again. And battery is full but sometimes display says 0 percent as well. This time i thought controller. Changed the controller with the one which had clutch problem after 2 years. But it was same error 30.
Unbelievable, maybe screen was broken. I connected the mobile phone with Speeedy android app, trying to connect to motor, no chance. Connection problem.
Just before getting mad, was reading that post, was telling to check the parts by changing one by one. Did no chance.
When i was hopeless, and was going to have only chance to use another. I found gear sensor cable was damaged, disconnected the connectors.
Magic was that finally. Everything was working fine. And my happy low battery consumption supporting, power downgraded Bbs02b 750 Watt to 280 Watt no was back. Because settings saved to the controller was the only copy i had.
Tomorrow i will also get a backup of the settings and email to myself too.
That is my 7 days long bafang bbs02b story with happy end. Soon will be happier when i repair the clutch and have really working backup. It’s not good to cycle over 500km per week and on top of a lot of stairs to go up and down.
Thanks to downgraded Bbs02 it’s easier and some fun including as well.
And thanks for the original post with some ordered general reminders and other experiences as well.
And bafang error Codes are and which causes what also interesting. I wouldn’t expect that much problem from a gear sensor
A year or so back I bought an electric cargo bike online. The company I bought it from is since then no longer in operation. Since a few weeks every now and then the display shows a wrench symbol and the number 30. At the same time the battery charge indication indicates an empty battery. The bike is still normaly operable. I think this is some sort of error code.
Unfortunately I don’t have any manual for the electric components of my bike, so no way to find out myself. I visited a few local bike repair shops, and no-one is familiar with the brand of electric assistance my bike has, and are unable to provide any help.
The label on the electric unit states «Bafang», which I guess would be a Chinese brand.
Does anyone know what this error 30 could mean?
Here is a picture of the error: 
Doing some more googling I identified this part as the Bafang DP-C07 display unit.
As asked in the comments here is a picture of the motor:

Hi, sorry for late reply, due to covid i’m working from home and relocated to countryside. i have not figure out what component is the faulty one, i suspect the controller has something fried or at fault. #1 i built my son an electric kickbike back in 2020 (bafang 500w front hub motor in the 100mm rear dropouts), and he had a wreck last summer. we put the bike away while he healed up, and did a little refurb (internal cable routing, moved the controller into the battery bag) last month to get it ready to ride again.
