- Fitting your BBSHD motor with a fatbike. This video looks at the size of BBSHD you will likely need in order to fit it to a Fatbike as well as some tips to make sure you get it on correctly and not have it come loose in operation.
The Fatbike in this video is a Specialized Fatboy. We are using the 120mm version of the BBSHD. This is the first of a series of videos that will go over all aspects of getting the BBSHD setup to give you ultimate electric fatbike.

I'm looking forward to the Cables Management video :)
I'll make sure to include something on that
Cap, great that you made a video where you encounter problems with the installation, that's the way to do it, we all have these and others and good advice helps many first time installers!
Thanks mate. Appreciated.
Just wanted to mention that your non egotistical non complicated and non “look at me I’m so clever” approach makes your channel the best ive come across re diy electric bike related info… although i do respect mr grin over there as well…
Mr Grin? Justin? Nice bloke as well. Definitely someone I admire. Appreciate the kind words. Cheers
Your videos are the best and look forward to your High Voltage controller installation and what kind of amperage, voltage and performance you glean. Many companies and motors try to upstage the BBSHD but it is simply an outstanding powerhouse with great reliability for a very fair price. Who would expected this from China but my personal experience is undeniable and credit where credit is due.
Thanks Luke. Cheers! Will do that stuff over the next few weeks
I bought a fat bike specifically for an ebike build. The plan is for the bike to be an allrounder, that is to commute 30 km to work (without being super sweaty), shopping trolley, camping and fishing vehicle and part time bush basher, with occasional trailer towing duties, all whilst backpacking my Maltese Terrier (a small dog with a big dog heart). All the things my current analogue Scott Aspect does.
I've been overthinking the build for 18 months now. One of my main conundrums is what motor to get with the current proliferation of mid drives. I originally decided on the BBSHD, but was concerned about the stripping of the nylon gears. Then the CYC Photon, but now towards the back of the pack, but I like that the crank shaft can be changed to a 68-73 in the future. Finally the TwoSeven DM02, it's draw back is only available to fit a maximum 110 BB.
I'm currently tossing up as to whether I should just do a cheap 750W - 1,000W build until there is more information on the new mid drives.
You could delicately do a cheaper build for now. I am yet to strip a Nylon on the BBSHD touch wood. Despite all the abuse I gave it as long as the gearing is right and you don't bog the motor down you would be okay. I have done most of what you list with mine. The TOSEVEN stuff might struggle if you will need the 120mm. Your dog sounds awesome btw! You are welcome on our discord if you want to post photos of the frame and get help.
So captain a step by step fitting of a BBSHD to a fatbike,cant wait to see the next one,brings back alot of memories,nice lekkie lock ring and nice fatbike...well done but I will be asking some awkward questions lol...nothing heavy just a few light shunting questions.❤😂
Anytime mate. 😊
I watched this video totally address of blue. I have no intentions of converting a fat bike. But I did realize I totally did not tighten up my photon enough on the installation yesterday. Thank you! Went back, and it was quite loose!
I think I used 50 ft lbs on the Photon. Good catch.
@@HighVoltageKits why so much less? Because it’s not as powerful?
@@HighVoltageKits thanks for letting me know that as well, I had Mine cranked way too high. I just checked the manual and it is indeed 50 Newton meters, or 37 foot pounds. Just fixed it.
the oil slick looks REAL NICE !
Yeah it does! Almost as good as that purple and blue you are rocking there
Park makes one of those tools that actually looks a lot like a large wrench that is completely open and I believe the newest version actually has a spot where you can attach a torque wrench. If they don’t make one I know Pedros makes one. I’m not sure if it has the torque wrench attachment. It basically looks like one of the large spanner wrenches that you would use on an old-school threaded headset to adjust the headset. I have a couple of them in my shop. I’ll have to look and see if they actually have the torque wrench adapters.
Thats really interesting. That would have save me the bother for sure. Although in reality it was not that much time to pull it.
You can get M6 spacers available in 1mm length increments at McMaster-Carr for the bracket spacing. A little spiffier than stacking washers. Also thank you for saying out loud you need 80-90 ft lbs of torque on the stock inner lock ring. Thats something a lot of people don't believe is possible but its critical to doing an install that lasts. The Lekkie One Nut tightening tool is a deep socket version of the Park BB tool that doesn't have the problem you showed us in the video. And of course its not cheap.
Thanks for that. You are right on the spacers. I have an account with them. I use polycarbonate sometimes as well for that bit successfully. I just had the stack already. But not quite as fancy as the one nut lol. I'll be going over the single speed setup this week if all goes well. Appreciate the comment. Cheers
This is great. Everyone says to just measure the width of the crank housing but you have proven that with a fat bike you need to allow for the frame width to allow clearance.
I just checked my moped style e bike but the fat tire is well back from the crank housing.
Could have cost me a major headache if I wasn't aware...Thanks a bunch!
Cheers Sparkie. Good to hear yours is OK. Is this a new build you are doing?
On hold due to monetary constraints!

Thanks for yet another top vid. Interesting point with the non slippage without teeth on bracket. All of what you mentioned was same as my experience fitting the HD to my Norco BigFoot 2020 bike. I did not use a torque wrench, which is obviously a good method, but so far so good.
Leckie locking ring is new to me, thanks for showing, great looking kit.
I look fwd to hearing about your single speed modification which I presume would require the extra power from upgraded controller + 72 v to run it. I went for an 8 speed wide ratio MicroShift drive, cheap, strong, good performance, no issues + it helped overcome shifting the awkward chain line.
You must have bigger pipes than me 😆 Great it's still on there. The next video will look at the single speed setup.
Can't wait for the continuation of BBSHD on Fat series. Im converting my Northrock XCF with 100mm BBS02 as we speak. Very curious what size chain ring you're going to use. What cassette, 10 speed, Im guessing. Modified cassette for a better chain line perhaps? Battery fitting, unless you use the frame bag and a triangle battery.
Sounds good! I will have some more on it this week!
I feel like this is where I came in. I started subscribing sometime during this build 1.0. Love the black makeover & the Lekkie blingification. Doesn't Lekkie make install tools (that fit their One Nut)?
Loving the 2.0 build so far. Can't wait to see the finished product. Your High Voltage kit has admirable finesse, to allow a smooth throttle with a 42:42 setup. (My setup wants to lift the front wheel on throttle with that gearing and doesn't approach your top speed, even in higher gears.)
As always, well done & I look forward to future vids (&builds).
Thanks Michael. I want to compile it all onto a web page so people can see it all.
Great video. One question: do you mount the motor touching the bottom tube or prefer to put a little rubber block between the frame and the motor (to avoid possible noises due to the motor hitting the frame)?
I just put it flush with this one as there are no cables the clear. Hopefully it works out.
I live in uk, I built myself same as your specialised fatbike , however i found standard factory bbshd is almost just about right. I also found fat bikes cannot handle speed anything more then 30mph is not stable at all, I reverted back to mountain bike!
That's interesting. I found it to be solid as a rock. Are you using the carbon forks? I got rid of those fast.
No questions they’re very solid indeed, My fatbike came with Rockshox Bluto forks!
The point I was trying to make was the safety! There’s no handling or traction I had to move my upgrade kit to another bike Marin Riftzone because it has dual suspension.
These rigid fatbikes have no traction neither any handling and with the upgrades these become dangerous!
Simply because these bike are very light in weight therefore do not handle like motorbikes!
I will remove the my comments once you’ve read it.
Best wishes to you
I have a similar frame on my Aventon Level. Which is already an E-bike, with a 500w hub motor. But I have been thinking of adding a mid drive, for more hill climbing power and top speed. I'd like to hit 40mph or so.
Is that worth trying? And would a S02 be plenty or should I just get the HD?
I would be adding another battery and controller. I think I would use pedal assist on the mid drive, and wire a throttle into both controllers so when using just throttle they're both running.
I'd be inclined to just go with one or the other. In terms of the BBSHD or the 02 I'd go with the BBSHD any day of the week.
You now can use the onenut instead of the stock two nuts I have the problem of a press fit 30 with a 46mm opening and it needs to be a 41 pf30 to BSA ???
Yeah I'm using the one nut. Adapters should work although I don't have a source for that one.
i advise clients to go up to 80nm on the steel lockring, I can see that not liking anything like that much (alloy)
does look very bling though.
I'll find out if I have to take it off and I messed up the threads on it! I think NM are higher than ft lbs.
1 ft lb = 1.35 Nm
@@billweaver3867 ah me div. thanks Bill
My fatbike has a 100mm BB with 20x4 inch wheels, I was thinking of getting the 100mm version of the bbshd but now Im confused how to check it'll work....
It might work. It depends on the chainstays, though. If you are on discord you can post some photos.
OH so you'll get a proper Torque wrench but not a bike stand eh?
Hahahahaha yeah. I'm stubborn at times.
