Luna Cycle is the worlds premier BBSHD dealer and do our best to offer the best options and support on this equipment.
The BBSHD is a complete redesign of the extremely popular mid drive the BBS02, every part is stronger and better. The BBSHD put out 150nm of force so much torque that you can stay in one gear and not shift as much as you would in the smaller drive.
This kit is for bottom bracket sizes of the most common sizes 68mm and 120mm (fat bike). Other BB sizes can be made to fit with our spacer kit. Read up about dealing with intrusive chainstays (article on fitting here)
The BBSHD heralds a new age of factory installed mid-drives. Unlike most other factory mid drives the BBSHD is designed to be mounted onto almost any bicycle currently manufactured. You can mate the BBSHD to any bike with a bottom bracket that is anywhere from 68mm to a much wider 100mm fat bike. The BBSHD is even now made in odd sizes (72mm & 120mm), including extra fat. We include with every kit so that you can make your BBSHD fit for almost any bottom bracket. If in doubt order the next size up....and our spacers will help you make the kit fit.
Install it on anything and ride it anywhere. With the proper gearing the BBSHD will easily climb stairs, go well over 30mph on the flats and much, much faster down hills. Singletrack trail-riding, cargo bikes, high-speed commuters the BBSHD can do it all.
The BBSHD excels at singletrack riding (article on singletrack testing here) as well as soft sand (article on soft sand testing) and works best with the Lunacycle Eclipse ring (independently reviewed here) or the Mighty-Mini chainring (available here). The stock 46T steel chainring on this kit is very heavy and has too many teeth for trailriding, although it works fine for commuting.
Its predecessor the BBS02 would sometimes falter if run at peak power for too long of a time but those days are over with the BBSHD. Completely redesigned with thicker windings, giant heat dissipating fins and a powerful 12 FET controller. There is nothing else like it on the market.
Go ahead, beat on it, the BBSHD was designed to take all of your abuse and more.
We are proud to be the first dealer in the world to have this drive in stock. We are shipping it with the controller hot rod programmed so not only can you get pedal assist when you want you can also get full throttle when you want it.
Regarding the BBSHD and Legal Street Use
Our drives come programmed for 750w. You can choose to have us program it with our hot rod settings if its for off road use on private property such as for a hunting vehicle or pit bike.
This drive is capable of 1500 watts in the right power settings.
If you do choose 1500 watt model, we suggest you also buy a programming cable so that you can change the firmware back to make it legal for street use.
The Bafang drive mounts in place of your current bike's bottom bracket and replaces your bike's crank set and front derailler if you have one.
The BBSHD can be mounted in a wide range of bottom brackets from 68mm to 120mm. To pick which motor works right for you: please see this guide. For most applications you need the standard size (68mm), and can even go a few millimeters over the usual limit of 73mm with standard by using loctite on the axle instead of the second lockring.
Our BBSHD kits come with one spacer kit good for 10mm total, if using a 100mm fatbike motor on a regular bike (73mm) some additional spacers may be needed and can be bought here.
Many people have found that the Bafang can actually be mounted to many types of trikes, which can be fun since many trikes are not good candidates for hub motor kits.
Maybe you have an old donor bike laying around you want to convert, or maybe you are wide open to which bike to buy and install this kit on.
If you are also shopping for a bike to install this kit, that is perfect. We recommend you pick a bike that is known to be compatible with this drive and has no known issues. Ideally a build report has been written on our builder forum so that you can follow step by step someone elses building steps.
Here is a post on our builders forum with a collection of build reports you can scroll through.

European customers, these chargers work with your 220v input- 52v luna mini, 52v luna advanced international, 48v plastic. These chargers do NOT work with 220v input- 48v luna mini, 48v luna advanced, 52v luna advanced regular
Here is some help picking which options you have available during check out.
This is a 30amp Kit and includes everything you need to install the kit on most bikes except for battery (which you can add at discounted price) all the batteries listed in the add as add ons are excellent choices for this kit. We have picked our most popular batteries as kit options and have made them available at a discounted price.
However you are not stuck to just these choices.
All of our 48v (see here) and 52v (see here) batteries are compatible with this kit as well if your looking for something larger in capacity. (more amp hours = larger size and farther range) We especially recommend any battery made with Panasonic PF or GA cells for the best fit for performance and range.
Battery dimensions are on each separate battery listing. We highly recommend making a cardboard mockup of the battery before purchasing to physically see if it will fit in your frame.
Display (dashboard Options)
The displays are the control center and the thing to most understand is they all display the same information (watts, battery indicator, speed, miles traveled, etc) so in essence just pick the display that you like the look of the most, since they all have the same basic functions.
965- Standard display and recommend if you dont have a strong preference for something else.
DPC-14 A full color display (read more here) that is a $45 upgrade option. If you want the fanciest best looking display this is it.
963- the smallest most discreet display...mounts by the throttle. A cult favorite. $40 upgrade price.
961 - The bafang default display that is not fancy but works perfect.
The Gearsensor is a $40 add on accessory that automatically senses you shifting when you change gears and cuts the motors power for a fraction of a second resulting in a smooth shift. Now with optional Gear Sensor...get almost the same BBSHD kit as some sale branded the "E-rad" at a greatly reduced price. This kit will come with an extra connector so you can add the gear sensor now or later without losing your e-brakes. We highly recommend the gear sensor upgrade which will give you butter smooth shifting.
Here is a link to the install guide on the Gear Sensor. This gear sensor is very popular option because before luna, only a few sellers were able to sale this and sold it at a huge mark up.
The Bafang has the option of connecting with your bicycle brakes and automatically cutting off power when the brake is tapped.
The kit will work with or without the brake sensors plugged in.
The Bafang kit comes stock with new brake handles that can replace your existing brake handles.
You also have the option of getting magnet sensors which allows you to adapt your existing brakes. This will help with users who have hydraulic brakes the sensors are not compatible with.
You can also choose to go with a brand new set of hydraulic ebrakes with the sensors built in.
Chain Ring Options
The Bafang comes stock with a 46 tooth chain ring option which works great, but is heavy and some consider it ugly.
You can upgrade chain rings to something with a smaller tooth count which will give you lower gearing and a few less mph of top speed but much more torque. Also the Upgrade chainrings are lightweight aluminum and look "blingy"
There are a number of different chain ring options which can get confusing.
If you want an easy choice, we recommend the Luna 42 tooth aluminum chain ring.... it looks better and is lighter than stock with lower gear ratio, but is only $40 option....Read more about it here. This ring you can interchange to a bigger gear like in the picture above....so you can go from 42 to 52 tooth for road speed freaks.
For more bling you can go with the Luna Eclipse (usually back stocked) or the Lekkie 42 tooth....both awesome but more expensive options.
The Luna Mighty mini is excellent for off roaders and turns the BBSHD into an off road monster, while loosing only about 4 mph in top speed. We also highly recommend this option.
All these chainrings have different offsets which effects your chain line which can cause you to lose a few gears when shifting. When you upgrade chain rings we throw in the stock chain ring as well so that you can try both.
In reality its something you should not worry to much about... most chainrings will be compatible with most bikes. Usually when there is a compatibility issue it is with a fat bike. Since when you go with an upgrade chain ring, you will also get the stock ring, you will have back up in the off chance you do have compatibility problems.
Here is a link to an independent review of the Luna Eclipse chainring.
Programming Cable option
The Bafang has many setting which will effect the way the power comes on especially in pedals assist mode. We highly recommend this $20 option because it will allow you to customize in the future.
Their are many great programming guides available on the bbshd online.
Pick your Bottom Bracket Size
The BBSHD comes in sizes made to fit the size of your bottom bracket. Please measure your bottom bracket before ordering. We have both in standard sizes (68-73mm), wide and fat sizes (74-100mm) and extra fat (100-120mm)
If in doubt about your sizing read this guide. If your bottom bracket shell is slightly longer than usual (for example 75mm) You can still use the standard motor. At worst you would just not use the second lockring which just acts as a jam nut and instead use blue Loctite. Same thing if your motor is a few mm above 100, you would NOT need the extra fat motor. You often can make a larger motor work with spacers but you do not need to go up a size if it is only a few millimeters difference.
Luna provides an exclusive spacer kit, which gives you up to 12mm of adjustment so that you can size your drive down in case it doesn't fit right away. Need more than 10 mm of spacers? We sell more here
If you are not sure about this one... pick the universal thumb throttle Thumb throttles are the safest and fit all bikes.
If you like motorcycle twist throttle, our custom Luna throttles are awesome.
Luna Install Tool option
There are some proprietary nuts on the bottom bracket of the BBSHD that can be a little tricky to install without the right tool (still very easy to jerry rig something)
However the Luna install wrench was made to make this task a snap and make taking on and off your drive easier in the future.
This is a $20 option. Luna manufactures this kit in their shop, and makes it affordable...the bafang install kit would cost anywhere from $65-$150 depending on which dealer you bought it from.
Question and answers
Here is a compilation of common questions we get with answers. If you dont find the answer you need please post it to our forums here.
Is there any difference of the BBSHD sold from the different sellers?
There are small differences in the program settings the dealers decide to program into the BBSHD or what power connectors they use...but for the most part the BBSHD is the same from all sellers. China sellers are selling them with stock program setting from Bafang which makes the drive much more slugish and slow.
How do i program my own BBSHD and what do i need to do it?
All you need is our $20 programming cable and then read this programming guide.... its easier than you think.
Why should i buy from you guys instead of some china Seller?
Our price is the same if not lower than most china sellers,. We are a USA company and can provide USA after sales support which China cant offer because of how far away they are. It costs 100 dollars to send a BBSHD back to China.
What is the top speed I will get out of my BBSHD?
From our experience the top speeds we see is 30mph. With high gearing and hard pedaling you can get a bit more...but the drive is not geared high enough for much beyond 30mph.
What is the difference of the BBS02 vs BBSHD? Which one do you recommend?
The bbshd is completely redesigned and is a much more robust drive that is more efficient and more dependable. You do not need to shift as much with the torque the bbshd offers and can even run a bbshd single speed, which would be unheard of on a bbs02. The bbs02 weighs 3 pounds less and is around 150 dollars less. We think the BBSHD is worth the extra price and pounds.
Which display do you recommend for the BBSHD?
The color DPC14 is by far the best display offering...the latest and greatest. Read an independent review.
How do I order the right BBSHD kit that fits my bike?
Which bike should i select as a donor bike?
We highly recommend you pick a bike that someone has already done a build on...that way your build will have no surprises or compatibility issues. Look at this section in our forum for a compilation of builds reports. Any one of these frame kits with documented build reports would be a great choice.
Can i fit the BBSHD with a modern press fit bottom bracket system?

Amazing performance. Needs better peripherals.
Posted by Josiah on May 18th 2017
I could not have asked for better performance from this mid drive. It was like going fast on a bike for the first time allnover again. Overwhelming freedom and joy.
I wish all of components were up to the drive and controller's standard. Huge brake handles, twitchy throttle, and a skipping heavy chain ring leave lots of room for improvement. Thankfully, there are great workarounds and aftermarket improvements available.
That being said, this kit is a whole head and shoulders above the rest. When I started putting everything together I found myself wishing I had gone the easy way and gotten a hub motor even though I'm a mechanical engineer. I'm glad I didn't.
Goes like stink!
Posted by Unknown on May 9th 2017
I installed this on a dual suspension enduro bike, 26' tires, 52V battery, 40T sprocket front, and 11T is the smallest on the back. This bike does about 35mph on the street! I love it, and ride it to work every day!
Helpful Suggestion: The "Hotrod" program is excellent, but even the lowest boost setting is still too much for use on a shared bike path. (The motor spits out ~350 watts in pedelic mode, boost 1). Recommend reprogramming the boost levels to suit how you plan on using the bike. Higher settings are awesome for streets, as they can push the bike as fast as you want to go.
Finding any excuse to ride my bike now!!!!
Posted by Dave from Pa on May 8th 2017
Ebikes are completely foreign to where I live so I went back and forth a million times whether I wanted to build one or not because I have never ridden one personally or even know of anyone who has one. I converted my 2010 Specialized Demo 8 II last week when I got the kit in. Taking my sweet time with the install (which was very easy) I got it ready to ride around 2 in the morning and had to take it out for a spin because I literally had no idea what to expect. I am blown away. This conversion opened up an entirely new realm of fun for me. I basically have a 50lb, silent dirt bike. I come from a motocross background of over 20 years and got rid of my CRF 450 last year because there are no tracks in my area anymore, all the fun places to ride are posted and patrolled or require you to going a lease that has a 2 year wait list if you even get on it at all. I got the itch to ride again and started looking into the downhill thing because it looked fun and somewhat similar to motocross with the jumps and whatnot so I picked up my used Specialized off of Craigslist and did some riding with it. This is the first bicycle I have owned or ridden since I was like 10 so I am not a pedal bike purist and it took me one ride with it in the woods to realize that pedal power alone just was not doing it for me....It reminded me of sled riding when I was a kid.....yeah that 2 minute downhill is fun but then you have to push it back up and I lost interest pretty quick. In comes the BBSHD!!!! Like I said, now I have a stealth dirt bike that doesnt require a downhill to have an absolute blast on. Doing this conversion 110% filled the void I felt I was missing from not having a motocross bike anymore and I can ride this thing anywhere. If I am cruising around and see something that looks cool or would be a cool jump I can hit it. I was super skeptical of this whole ebike thing. I must have added this kit to my cart and removed it 10 times because I just kept thinking I was going to spend all this money, get the bike together and just be completely underwhelmed. Not the case at all. Best purchase I have made in a long time and my hats off to Luna!!!!
It's soooo quiet. BBSHD/48v17500 AH
Posted by Stuart on Apr 24th 2017
Love it, quiet and fast. Easy setup following the Luna videos and following the Forums. I could have spent a lot more on a built ebike but added the BBSHD to my home built Salsa Fargo and it's incredible! Don't hesitate, get yours now!
Love my bike
Posted by Sam Stewart on Apr 8th 2017
My bike is the best entertainment item I have ever purchased. Coming out of the box the kit was a little intimidating. Having no instructions was rough but watching the Luna videos a few times made my install really easy. Every thing went together really well. Worst part of my build was getting the old parts off. I live in the San Francisco area and have a lot of hills and trails to ride. My bike climbs like a goat and has a top speed of +40 mph (My wife clocked me on one of my rides at 44 mph). I am more than satisfied with my purchase.
Easy install instant power
Posted by Malik Thomas on Mar 6th 2017
Well after all my research between YouTube and all the forums I finally got the bbshd 100mm I must say I impressed. The whole install toke me about 2 hours and that was with me taking my time. The only issue I ran into was trying to get the motor thru the BB it got stuck about half way. I had forgot to lube the motor first but other than that smooth sailing
Easier to install and more fun than expected
Posted by Unknown on Jan 29th 2017
I dont know anything about bike building and installed this thing myself by reviewing videos onl;ine. since i know nothing about bikes it took me all day Saturday and a couple hours on Sunday to assemble ..This thing is a blast so smooth so quiet so fast...I took it down to the local bike shop and every employee in the store lined up to ride it ..They all said it blew away the prebuilt ones they carried from Electra, Specialized and a couple other brands. Fyi my donor bike is a 2017 Specialized Roll.mens version
bbshd 1000w kit with hot rod program
Posted by Unknown on Dec 5th 2016
Onley had it goying about 2 weeks now and it's holding up grate I use it mainly for hunting so I am goying down some rough trails and up and down some pretty good hills has plenty of torque for the hills paired the kit with the shark jumbo pack 48v 17.5 ah and can run it all weekend without charging my only advice for this kit is that make shure that your bike you are planning on putting it on has a 3 pice crank and not a one pice dident see this on the website aney where you can make it work but just save your self some headache I noticed the kit is realley made for mountain bikes judging by wire length if you were to put it on say a big cruse bike you may run into wire length issues giving it 5 stars it's a great kit but it would be nice to have a quick reference on like bikes that are pretty much bolt on plug and play if you are looking for a quick build with out having to go pages of forms to find out what you need to do
Battery to motor wire
Posted by Russell Reese on Nov 18th 2016
The electrical wires connecting the flat fish battery to the BBSHD motor are too short for my Santa Cruz Bullit downhill bike. The battery is mounted on a rack attached to the seat post. A guy named "swimmingmagnets" posted a blog that gave the answer. He showed how to cut and splice the wires, and replacing the Anderson connectors with XT-90S Anti Spark connectors. These anti spark connectors prevent a spark from zapping the battery when the connectors are detached for charging the battery. Otherwise, the kit installation is going well.
plenty of power
Posted by Unknown on Nov 15th 2016
This motor rocks, Easy to set up, and flawless so far Been using it daily for 2-3 weeks. I set it up with a 52v shark battery, I'm getting around 1500 watts out of it. the bike is a commuter, being used in the mountains. no problems getting up the hills.

My bike is know turbo charged. This is a great kit. My heavy dual suspension mountain can know do 35 MPH on flat land.
The thing is you still get plenty of exercise , you still have to paddle it just takes less to go fast.
This thing is AWESOME.
Posted by Brian Manlove on Oct 29th 2016
I'm a complete newbie to e-bikes... I've had a lot of interest in them for a couple of years, but reading about issues with different drives coupled with some crazy pricing was enough to stop me from purchasing one. When I read the reviews on this drive, and with Luna's pricing and reputation, I bit the bullet and pulled the trigger. Installation in my 20-year old Trek Multitrack 700 was straightforward. My only complaint is that it would be nice to include pictures of the wiring harness hook-ups. I am getting close to 40 kmh with the stock controller settings.
Another idea for Luna would be to sell anew adjustable fixed chain guide as a replacement for the front derailleur. Since the bike now has a single sprocket there, I had to use a hack to get mine positioned so that the chain stays guided into the front sprocket as the angle changes from the 7 rear sprockets.
AWESOME PRODUCT, LUNA!!
I'm loving it
Posted by DougB on Oct 21st 2016
I received the BBSHD kit with the full color display on Monday. I had already removed my bottom bracket from my full suspension Trek Fuel 80 so when I installed the kit on my lunch break it took me less than an hour. I power it with a 48 volt pack and the motor has more than enough power for my 8 mile commute on a gravel bike trail. I rode another BBSHD bike and didn't like the PAS settings but LunaCycle did a great job reprogramming their kit. I can work as little or as much as I want. The bottom line is because of this kit, I can now easily bike commute to work whereas before, due to the hills, bike commuting was out of the question. Thank you LunaCycle!
BBSHD 1000W Fat Winter Commuter
Posted by Jeff Blackmore on Oct 13th 2016
Just finished my build on a Surly Pugsley and it is awesome. This is the third E-bike kit that I have had for winter commuting and it is by far the best. It went together well and has worked flawlessly so far. I am looking forward to the snow!

This is as close to plug'n'play an electric conversion can be. I watched the video link on this page, and installed the entire kit in about 2 hours. All cables are color coded, zip tie everything to the frame and handlebars and hit the road. The most technically challenging task is soldering the battery leads to their designated plug, and if you don't know how to solder, it's an easy skill to learn. Now I ride my bicycle as I always have, but the hills are so much easier on my knees. I just couldn't bring myself to spend $3000++ on an factory built e-bike with less performance and range than this kit. Thanks Luna!
Great kit for (even) a eBike neophyte
Posted by Mark Laffoon on Sep 23rd 2016
I've ridden a few eBikes from rental places and, although fun, i found them a bit underwhelming. After a bit of research I decided to build my own mid-drive bike. This kit was very easy to install, especially with the extra bits provided by LunaCycle: the spacers, the wrench, and the default settings on the controller were great. The whole thing went together in 2-3 hours except for ...
I ran into one self-induced issue when i decided to re-grease the secondary reduction gear. I got an immediate response from LunaCycle support for my plaintive email with just the advice i needed. And it turns out the BBS02 was adequately greased contrary to internet rumors so it was really a waste of time on my part.
I've ridden the bike less than 100 miles at this point, so i can't comment on the long-term success but so far my advice is: great hardware, great kit, just get it.
