You guys are super helpful! Really appreciate all the help.

[@subinct]

Thanks for the tips. Fixed my Bafang from being ForError 21.

[@mjk9674]

Thanks, you solved my error 21 code on my new Accolmile. Manual tells me nothing! My speed sensor was not lined up due to a cheap zip tie mounting system for the sensor. A little Gorrila tape around to zip tie secured it much better. Works perfect now. Thanks again for the great info!!!

[@RitchieCaron]

Thanks for that info. The magnet was turned out and fixed within a minute of subscribing and liking this video.

[@eileenjohnston6835]

Thank you soooooooo much! I am getting an error ( !21H) and hopefully your suggestions will correct the problem.

[@taihunter998]

Thanks for the tip made it home from work without having to just pedal

[@lukefox2325]

Great video. Direct to the points. Thanks.

[@n.a.3734]

Its 2nd time .. helped ..👏👏first was extension of bbs axle 73mm to 100mm👏👏 & now this!;) so I’ll order from u!;)

[@ciberbri59]

You really get to the point quickly and succinctly. Will error code 21 clear by itself once the condition has cleared or does one have to go through a code reset procedure?

[@shipsidedutyfree9981]

Good video , Verry clear fix for error code 21.

[@lilofeegirl]

Was really helpful, thanks 😊

[@loumax5856]

Thanks for these videos 👍👍

[@resellingwiththenobles]

Worked perfect!!

[@spokanefut]

I don't mean to point the finger at Golden Motor specifically, but I've yet to see ANY of these videos where the sensor and magnet are actually set up to be at 2mm clearance from each other. Most are like 2 CENTImeters from what I've watched and they do function, more or less. But if you do precisely set them at 2mm, they work a treat. Good luck.

[@nemindakarunaratne2291]

Thanks for the Info

[@bogdand1475]

hi, my bafang DPC18 display shows error code 0 - 21. However the bike seems to be running absolutely perfect. Any tips?

[@usaisamess8880]

It helped!

[@nicholaschai4458]

My speed sensor is lighting up but the display doesn't show the speed

[@vladimirdjokic5741]

Appreciate it.

[@pabloduranpuente2016]

Usefull

[@richardmack7700]

Literally had to move the sensor a lil closer to the magnet 🤦 well thanks 😂

[@simonpage1472]

I had damaged my 1T4 cable and replaced it. With the replacement cable, the throttle is unreponsive and I get Error 21 instead of a speed reading. Everything else seems to work. I have yet another new cable coming in the mail. Anyone ever have something similar happen?

[@richardmack7700]

Before you think the speed senor is faulty, make sure it's really close to the magnet.but not touching.

[@godislove1767]

Can I bye battery

[@manoz6194]

Had this error, the magnet was aligned, the light was activating but it turned out the threaded nut had loosened so the connections was slightly loose

[@enam100]

How do you clear the error code on display?

[@starmania909]

one more for you guys mine quit and i just had to really push that cable in hard to get a connection

[@TheZoinxtorque]

i have a bbs01 with another type of harness .. bbs01 for blaupunkt project !! and i belive my speed wirings sensor is 4 by numbers!! instead of 3 normal !! black red blue green instead of black red white normal wirings bbs bafand motors !!

[@SokaBalogh]

unfortunately my sensor is in the motor, ECONIC ONE SMART CROSS COUNTRY and di not work, I bought 3 days ago, probably I need to send back

[@mikethomas6051]

Well the vid is for bbshd so not applicable to your motor 😂 get a proper mid drive, the Bosch and Yamaha suck, bafang or cyc if u plan on off roading or hill climbs

[@dennismorin7506]

I have error code 12 I was hoping you guys were dyslexic

[@nyctus2024]

My sensor lights up but does not detect a magnet when it passes by the sensor

[@mikethomas6051]

Its not close enough to to sensor, 3mm is fine, him saying 1-2mm is very close margin great for very tru wheels but not recommended, 3mm is sweet spot, make sure it passes the stump that sticks out, thats the sensor part
