Bike chain keeps falling off the Bafang BBS02 ebike -- a fix with a happy ending

- the chain keeps falling off the ebike when going down hill over bumps. The original chain guide no longer fits the big chainring that comes with the Bafang BBS02 motor and had to be removed. I bought a third party chain guide but it didn't fit the bike frame. The last option is to change the Bafang chainring with one that has deeper groves and higher teeth, and it worked!

Dude! The music😮
Would of been a better video if shown us how to actually change the front chain ring.
Thanks for making this videos. My chain slips on the bigger cogs due to a bad chain line. Would this chainring fix that issue? Also, do you have a link to this chainring? Thanks
If your chain falls off while riding on a flat surface with no bouncing then the issue is not the chainring. I think you will need to adjust the rear derailleur limit screws. If you do want a new chainring like the one I’m using , you can search for in ebay “ebike 104BCD 40/42T chainring for Bafang”. I don’t remember the brand or the seller’s name. It’s made in china.
Did u give up on the chain guard totally then? I'm sure u could adapt that to fit ur Frame
I gave up on finding the correct size chain guard. So far the chainring has been working out very well. The chain has never fallen off since then
@@imdragonslayer good to know. Mine with the stock bbshd ring jumps off even if it looks at a speed bump! It's ridiculous. I have ordered a new chain ring also
Best to go with a Lekkie Bling Ring. If you're doing serious hills, switch to a 28T and you'll be amazed at how little your motor works compared to a 42T. Ditch the chain guard, ya don't need it.
If he switched to a 28t on a BBS02 or 1 you'd have an insanely high negative offset, which will mess up the rear gears usability. I would say buy a 36t it's a decent comprise, take breaks if you're worried about putting the motor under too much stress, these things aren't meant to be treated like motorcycles regardless of the gearing you need to take breaks and let the controller cool down. common fault that they overheat. You can't fit a bling ring that size on a BBS02 or 1 just in case you're curious
I forgot about the chain ring thing & enjoyed “for a few dollars more”!!😅 where is this the scene same as the movie 😅😂😂.. btw I bought bling 28 no speed , 36 bling better one time investment!!;)
Can you let us know where you purchased the chain ring from ... model no... and link to where you purchased would be greatly appreciated. Thanks
That last section looks crazy steep and rough without the motor it'd be a very slow painful experience even for the toughest.
I bought it from a seller in Ebay; don't remember the seller's name. You can search for "e-bike 104BCD chainring for Bafang mid-drive" 40/42T
You get them off wish for 15 pounds 💷 that's for the spider aswell as the chain ring but I don't think they will as good quality as the lekkie bling ring
Always use an ebike rated chain and you can get one with the quick links
KMC makes a good one. Rather costly - 40+ $ - but reliable behind a BBS-HD. I have three, and waxed all three this AM. (Crock pot takes an hour-plus to warm up, and then five to ten minutes per chain in the hot wax mix.)
Half paraffin, half Beeswax, and add heavy gear oil to plasticize and supply lubrication. The more oil, the better lube - and more *mess,* too. You’ll want to tailor this last to your own preferences. I originally started with a fair amount of oil, and have cut it back a *lot* because of the sludge that accumulated on the cassette and other sprockets…
Hi Wat is the top speed with 42t chainring??
Yes
@@imdragonslayer yes?? top speed?
The chainring is 42T meaning 42 teeth
@@imdragonslayer top speed ?
@@mygoalcrash8077 Top speed. Don’t remember. Probably 25mph default. But there’s a menu setting where you can set the wheel size smaller to say 20inch and the speed will increase accordingly, assuming your bike wheel is larger than 20”. I can go upto 37mph with peddle assist. Downhill is very fast which I have done 45mph
The best solution is a chain guide
Oke
Falling off generally means your rear derailleur needs adjusting or your chain is too long
narrow wide chain ring
Music is distracting
Clutched derailleur
@Yute Hube I had this issue, not to do with the chain line at all sadly
That would work, but isn't that far more expensive?
Im nor sure how many clutched derailleur Shimano makes. I have a saint. Probably just over $100.
Way too much
M U S I C over the voice-over.
Ebike sx use the most low in sprocket components you've ever seen because I know that nobody petals them that's a lie no 1 is losing weight no 1 is working out he bikes = failure and or fat!!! $1500 radrunner no chain at all!!!its ruined!!
Use poorly installed low-end components and this is what you get. 36K+ miles and I've never had a chain break or skip a gear.
Actually my friend has the exact same setup and he's using a nine speed along with a full suspension bike, and he has no issues. Poorly installed, what are you smoking? Give the guy a break. If he's using a wider chain 8 speed and has a hardtail he'll have these issues guaranteed, the stock chainring has very narrow teeth more suited to a 9-11 speed setup
