Nice video. Open the grease tube next time from the other end then you can just remove and refit the plastic lid. Also Mobil SHC I believe is the updated version of Mobil 28 and much more readily available.
Thank you for this! Will keep that in mind
That thermometer strip is a brilliant idea, this is getting a thumbs up from me on that alone! love picking up new ideas for my bbshd.
No need for thermal strip due to open source firmware. There are also rare nonchalant reviews about throttle being smoother with stock controller and open source firmware. The pawls in the freehub doesn't seem to make snapping sound anymore.
@@uvwuvw-ol3fg Yes just looked it up, very exciting, now i can get my 28a controller to open up to 30a! that 2a increase does matter, my throttle doesn't have any issues, not sure what throttle is being widely used but i only have a thumb throttle. Did you flash the firmware, how easy was it and were you concern about bricking it.
@@uvwuvw-ol3fg Hey, do you know if a controller that had an error on would be ok to flash with it being not connected to motor and only using battery along with programming cable, thinking about trying it with one, be good to have my £100odd controller back up and running as an option.
Nice video very interesting nice tools, I didn’t see you check bearings or replace them you must have been happy with them
I bought one of these brown gears and installed it and it's been good. I am just running a off the shelf bbshd with a 52 volt battery. My original nylon gear was perfect condition and that's was after 33000k but I changed it anyways but I did notice that stock nylon gear uses plastic for its top needle bearing and it was wearing.
That's amazing you rode 33K and the gear was ok. What type of bike, motor, chainring size, wheel & tire size, and riding surface did you mostly ride to get that mileage? Did you open motor to clean, re-grease periodically?
Wow nice I hope I can surpass yours.
LOL i hope i get minimum 5k before anything happens @@rodolfobaliga7577 i have bbs02b
alright this video is awesome, convinced me to swap out my steel gear
I'm glad to hear! Ty 👍
Great video, well done and thank you for sharing.
Some of the socket screws are stripped - some for the main gear housing, and secondary gear cover. Everythings been working fine since I last opened everything up - but wondering about getting someone to rethread so more than one or 2 bolts hold. Also used 'liquid gasket seal' to replace the torn one.
Great video sparky 😀🔥👍🏻
Thank you!
@@SparkyBikes how is your bbshd running??plan to grease my nylon and main steel gear tonight with mobil shc 460 red grease over 4k miles unopened sound very dry🤔
I have used Aeroshell 22 grease, the counterpart of Mobil 28, a lot. And it's not at all suited for gear lubrication. It has very low film strength and not so great extreme pressure ability. The incredibly high temperature resistance of these greases is of absolutely no use for this motor. The windings will be burnt way before any decent grease gets to its drop point. but the lack of adhesion to the gears, especially the large steel gear makes it totally unsuitable. Especially considering its astronomic price. What I have found to work extremely well is polyurea grease such as Lucas X-treme Heavy Duty and calcium sulfonate grease such as Lucas Marine. There are obviously other brands selling analogous greases. For extra performance I just add some 1.6 micron PTFE powder.
Why are you using such a small chainring? I see no reason to have a chainring smaller than 40t as the chainline is very bad due to a lack of offset. Along with a wide range cassette (11-50t) you get up any hill and have great top speed. 11-50t cassettes are available in 9 and 10 speed from china, for 10 speed I would go for the Zrace brand which has hardened sprockets, as regular sprockets will get cold forged by the force of the chain. If you want the chain to last any significant amount of time, you need to wax it with paraffin/WS2/PTFE. it makes a world of a difference. an oiled chain will grind down itself, the cogs and the expensive alloy chainring very quickly. the chainring will end up not releasing the chain due to hooked teeth
Thank you for the info on the grease! I run 36T & 32T on the back for a closer 1:1 gear ratio for this bike. But I do agree on the chain line, I have it set up very close to the other end of the wheel and do have a 42T chainring with a better offset so will be changing that next time I swap the chains.
@@SparkyBikes other point concerning the transmission: I actually prefer using the 42t chainring along with an 11-50t cassette, since I'm using larger cogs for a given speed. Larger cogs mean more chain engagement, less tooth damage and chain skipping at low rpm. The freehub body will still take the beating. With 42t-50t front-rear you get amazing hill climbing ability.
wish they would make one for the bbs02
Man that Peek Gear is hard to find these days! Nice work!
Noticed your thermometer on the drive - not a bad idea for a simple warning. Where did you pick it up? I'm seeing a lot of them for aquariums, but nothing that hi-temp.
It's definitely popular so hard to get but Mr. HV/High Voltage on Discord I'm sure can get you hooked up. If not, I know he'll have some more soon. The temperature controller is built in with the HV Kit. The new Eggrider I have also has a built-in temperature (albeit in a very small display within).
Its also very expensive, Triple the cost of the nylon one.
Sir, Thanks for your video, i have some questions concerning bbshd motor:
1. Which is the most reliable gear to use on that 3 types of gear? And what are the advantages and disadvantages?
2. How many kilometers before replacing the gear? (nylon/steel gear).
Treat your bbshd/nylon gear well and it will go for thousands of miles, mine is going like new after 3000 miles, clean and re-grease once a year, don't use any controller over 48/52v, avoid programming it to just run high amp current in all pas settings, don't abuse the throttle and avoid having its starting current set too high and its equivalent pas setting level, chose a chain ring that suits the terrain ( flats 42-46t with some hills, 36t for areas with a lot hills/climbs ). My advice do not use steel gear, they make the worse noise, they damage the rotor shaft, there is a reason other than cost for the nylon gear, vibration reduction, it acts as a fail safe to protect the motor core, helps with temp control. The peek gear looks like a great alternative but it costs like £120 in the UK, triple the cost for a nylon one. I've not tried the peek gear but my nylon gives me a lot of confidence with it, I'm running the full 30amps, use a 42t chain ring, ride every day with it too work and off road at my local trails.
@@mikethomas6051 thanks a lot sir for the infos and advice, more power.
@@rodolfobaliga7577you are very welcome, hope you join the ebike family especially the bbshd one.
i was told by befang and others not to put any sort of grease on that peek and nylon gear as it needs to be dry because the run on friction
I've been putting less grass on the PEEK gear for sure as they spread a bit but I haven't heard about not using any grease😳
they come pre greased by Luna. This is interesting..
Hi what kind of silicone would you recommend for the inside? Can I use dielectric silicone grease for where the cables go?
nice vid
Is the peek gear better than the nylon? For higher pas assist?
I am running 52v right now. When you upgraded to 72v did heat go down due to lower amperage?
How'd u clean the peak gear hole before entry - just paper towel? About to do the same
Did you make the stabilizer or did you buy it?
From Luna Cycles. It works as much as it looks a bit hacked 🫢
another question, the silver support for the motor at 00:50 where is possible buy? thank you
Lose the custom bracket and get the proper BBSHD socket. The tool you have is a nuckle buster and will never get the nut tight enough. Mine has never moved since using it. My motor is also angled much closer to the down bar
Good helpful video, just one thing, the motor seems noisy, is this normal, as I thought the bbshd was much quieter, I’m looking at buying one, but not if it’s noisy when I’m riding
This one in particular was with the steel gear; I got rid of it since and went back to PEEK. Along with ceramic bearings on many that seem to make it even quieter.
@@SparkyBikes Thanks for replying, now it makes sense
@@SparkyBikes that noise was why I never even contemplated a steel gear, it looked a good idea but I could tell it had a few draw backs
Wow...awesome. Are you able to share the drawings of your stabilizer bar in dxf or dwg (autocad format)?
It's store bought; a little soft but it's been working fine 😁
Man I had sooo much trouble getting that clip connector off on my bbs02. Took me months of procrastination cause I got stuck on it.
I have two questions by the way.
1. What silicone do you replace the white silicone with?
2. You said I can make my own gaskets. How? Can I use silicone instead?
Okey that was more then two but...
I actually didn't replace the silicone but I'm guessing any 100% silicone would work (but don't quote me lol).
The gasket can be made by using Fel-Pro 3157 on Amazon. They're a gasket maker sheet. Slightly thicker but also more durable. You can make quite a bit with the whole sheet.
Make sure you use a neutral cure type silicone. Acetic acid cure silicones wont do the electrical components any favors.
where did you get the thermometer sticker cannot find one on those temperatures
It came with Mr HV's kit 🙂 Although I'm assuming you can get this anywhere like the ones they use for aquariums.
@@SparkyBikes i cannot find one on this temperature range aquarium one go to 40 celsius max. does it work? what is the max temperature you have seen on it
Loving the chainring. Didn't know there was other options other than bagang and lekkie. Where did you get yours.
This 36T is from Luna Cycles; the only thing with the 36T is the chain line becomes very tight to fit larger cog with the low offset. There's also the 42T I got from AliExpress made by a company called PSR which looks similar to Lekkie but cheaper. No issues with it so far.
@@SparkyBikes nice ima look into that one. Don't like the ugly stock 46t that comes with the kit.
Yes, the stock gear is so heavy and bulky, the first thing I upgraded! The 42T has better chain line option.
@@SparkyBikes another thing, did you ever have any issues with gear slip in the 11t and up first 2 cogs. Cause after about 2 weeks of riding on a brand new bike, my chain feels like it's slipping but everything was brand new
Here's the link of the 42T: US $63.48

When the nylon gear goes does it make a wining sound and no drive ?? Need to know asap or what could it be
There would be no drive, yes. I'm pretty sure it'll have some whining noise. I always recommend the PEEK gear if at all possible 🙂
Where do you buy the peek gear?
Lunacycle
Is that a Lekke Blingring? I'm in Sweden. Do you know if there is some other sort that I can buy from aliexpress for the bbs02?
It is actually from AliExpress. I was worried about the quality but it's been great! "PowerSurround Store" is where I bought it from there. "PSR-EBIKE" is stamped on the chainring.
@@SparkyBikes thanks for your answers and the vid. It helps a lot.
Thinking about doing this also, before I even use the new motor for the first time. How is the gear holding up?
Excellent! I'll open her up again soon to see how it's doing and see if I still need to go with thicker grease as it's pushing 4000 watts currently.
@@SparkyBikes What controller are you using the ludacrous controller?
It's Bafang 750C 😀
@@SparkyBikes your display allows you to run 4kw?
@@SparkyBikes hi put a grease nipple on the motor and get grease gun then couple of pump every week
bought a spare motor side for the bbshd i could smell some burning smell sometimes when i ride probably cuz im putting lot of strain on the motor ive been riding in 7th gear all the time. it wasnt until i went to 4th gear did i hear clunking from the motor pinching my brake cables cutting my power off?
I'd open up her for sure and see what's going on. These motors like low gear ratio and high RPM so I try to keep my gearing no lower than 1:1.25 if not closer to 1:1 especially once you go with a higher wattage setup like the Mr. HV's kit I have.
Whats really making it hot is from the amount of Amps your pulling from the motor at a given time
hello, where buy PEEK GEAR and MOBILE 28 GREASE ? thank you
Mobil 28 is old version so I'm using SHC 100 also by Mobil that's identical but slightly better. You can buy them on Amazon.
May I ask where you got that torque arm from?
You can buy from luna cycles
Why didn’t you use blue lock tight
Metal gears in this type of apps MUST work in oil bath ALLWAYS and should be properly aligned by shimms and preloaded with specific force. You are more than lucky you didn't break shaft. 🤦
