Works, but it's limited in what it can do and needed some mods Hello, I've been building home-brew electric bikes for the last couple decades and this is my 7th build. For this build I used a full suspension bike: Polygon Siskiu T7 battery: EGO Power Plus 14s 12ah (56volt) Terrafirma battery adapter rack: Aeroe Spider + Voile straps to hold my battery The build was pretty straight-forward, just pop your bottom bracket off, toss this motor in and route the wires. I didn't buy the optional spacer kit but ended up needing it. Fortunately I had an electric "bike shop" around the corner that sold the exact spacers I needed (Ace Hardware). I chose the 30 tooth option and find myself regretting the "hotrod" programming option because my riding style ended up being mostly power 0 and power 1 250 watt. On the rare, super-duper grindy hills it was nice to kick it over to power 2 500 watts but this will overpower any hill in granny gear, never needing power 3. Hotrod programing disables your ability to limit power levels so an accidental click over to power 3 it wants to fling you off the uphill switchbacks so I would have rather had Bafang's stock 750 watt limit with either 5 or 9 increment settings going up to 750w max. Another mod I did was to drill small holes for mini-bungee hooks into the cooling fins to help pull the nose of the motor up. This is because of my biggest gripe about the motor, motor strikes. If you strike a rock hard enough it knocks the motor back and buzzes the wires against your rear tire. For hard singletrack I found myself really having to be picky with my lines, the black diamondy kind of stuff where you might have pedal-strike ends up also being a motor-strike situation, the most egregious are the rock steps where you wheelie up a rock but end up high-centered; major bummer. I've knocked out a number of particularly gnarly trails with this kit but the dangler down there is a particularly bad handicap. Despite using throttles on my last 6 builds I ended up not liking the throttle on this setup ultimately doing away with it entirely. The throttle is just too jerky and adding a bit of power to your pedal strokes with an up/down button worked much better for me. I was relieved to see that the bike shifts fine under power level 1 (250w) and ended up not needing the gear sensor. I tried the EGO 5ah battery. I found that I hit about 15-20 miles of semi-spunky trail use before it goes flat. Being that I tend to go on 20-ish mile rides this gave me battery anxiety and I opted to sacrifice weight for more overhead and haven't regretted the 5 to 12ah switch. All in all I do not recommend this motor. Black diamond single-track riders will find the motor hangs too low/vulnerable. Double-track, gravelbike, and commuter riders will find that hub motors are better/more reliable and don't add wear to your chainline. I think this motor works fantastic on blue square upper-intermediate trails that don't have chonker rocks, fantastic for any situation where you need a granny gear to tackle some serious incline but not the right motor for most people.

After considerable research back in 2018, I decided to purchase my BBSHD and 52V 17aH triangle battery pack from Luna Cycley. Over the last few years it has been flawless. Recently my mid drive started acting strange and since I didn’t want to lose my bike for too long, I purchased a new BBSHD. It was here in less than a week, installed and back on the trail. I will investigate my original motor and try to put it back in service on another bike. In addition to motors and battery, I have also purchased many other parts and accessories from Luna without hesitation and will continue to do so in the future. Great products, service and friendly attention. Thank you Luna !

Installed on my daily commuter S73RX and totally transformed the bike. Running both mid drive and hub motor for easily cruising 35 mph with twice the range. Easy to install and preferred going through Luna vs Amazon for the customer support and quality of the battery.

I bought a Trek Donane A2 to convert to an e-bike. My son had done a Luna conversion on his bike and recommended the Luna kit. This is a commuter bike, but it does handle gravel well. I live on a gravel road. Two things had to be changed in order to install the Luna kit, the handle bars and there was a bit of aluminum sheet metal that needed to be trimed so that the motor would fit neatly on the bike. The droop bars would not work because of all the hardware that has to mount on the bars. I put streight bars on and cut them down to 22 inches sided to side. I would recommend going for 23 or 24 inches. More real estate for mounting stuff on the bars. I also increased the tire width to 38mm for a better ride. I have 92 miles on the bike since I converted it 2 weeks ago. The only issue is getting the rear derailleur set just right to get all 8 gears as it should. I am getting very close to perfecting that system. I have less than $2500 in this bike. I think that is well below what I could have bought an e-bike ready to go.

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 offer spacers and adapters on this page and our parts section 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 (iif doing so order extra spacers)
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.
Which Bike?
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.
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.
Which Options?
Here is some help picking which options you have available during check out.
Battery Choices
This is a 30amp Kit and includes everything you need to install the kit on most bikes except for battery. All the batteries listed as options are excellent choices for this kit. We have picked our most popular batteries as kit options and have made them available for easily selection.
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 48v or 52v 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.
The Gearsensor
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.
eBrake Options
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 does not come with brake sensors, you can select the brake levers option made for standard cable actuated brakes.
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 single track riders 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. If this is a concern, for the chainring with the best offset and therefore the best chainline go with Eclipse, this will be most likely to let you use all the gears. Regardless of which ring you pick, 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.
Watch our video on different chain rings
More information on chain ring selection. (Also check out the BBSHD wiki for some basics of chainring choices.)
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). Please note if a size is temporarily sold out the option may be autohidden until restock.
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 highly recommends the install helpers for your first time install so that you can size your drive down in case it doesn't fit right away. Need more spacers? We sell more here
Throttle options
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.

I have a GT pro Performer 26 that I really want to convert. It is a single speed bmx bike though. I understand the motors would rather be in a higher gear spinning faster though. Would I be risking blowing the motor on something that is fixed speed? Especially if I'm wanting to run at 52 volts?

Hi there. Specs for that frame indicate it has 22mm bottom bracket. BBSHD motors are built to fit inside of a standard BSA bottom bracket shell with inside diameter of roughly 33.8mm, so I would highly recommend measuring that shell before pulling the trigger on any mid drive kit for it.
Generally speaking if the motor is spinning fast that's not going to blow it, the motors like to spin fast, it's when they are spinning slow while going uphill that could risk blowing it, and on a typical bicycle you would downshift to ensure it can continue spinning fast while going uphill so that it keeps running efficiently.
As such, it might not be the most suitable on a single speed bike, not because the motor could blow but because without the ability to shift the motor can't take advantage of one of the main benefits of being integrated into the drivetrain.
When will the Bafang BBSHD restock? I've been waiting for over 3 weeks and seems like it hasn't restocked?

What size motor is this BBSHD motor? A 1000w motor that can peek at 1500watts, yet be programmed to 750w for street legal, is that it?
We will send a verification email to confirm your answer. All responses are subject to store approval.
The hot rod programming peaks at 30A, the street option sets this peak a bit lower. Actual peak wattage output will depend on the voltage of your battery, watts = amps times volts. Like any BBSHD you can reprogram it with a $20 program cable for any current you want up to 30A
If I order such an engine, will I be able to receive it in Bulgaria? Do you make deliveries there?

What's the warranty of the BBSHD MID DRIVE Hot Rod Off Road kit? I bought mine about 11 months ago and have put about 800 miles on it and I have now lost 70% plus of power in my motor over the last couple of months? It rode comfortably without peddle assistance at 35 plus MPR two months ago, now it rides at 12-17 MPR and or around 22MPR with peddle assistance. I dont know what the problem is! I dont think its the battery. I do ride in cold weather because its winter and the temp outside when I ride is usually around 30-50 degrees, and the battery is usually kept charged and inside the house and not exposed to overnight cold weather. Does anyone else have this type of problem, and or what do you think the problem might be, & how do I fix it? And again, whats the warranty of this motor kit? Thanx!

Unless it was reprogrammed the only way it could be the motor is if the windings in the core were partially burnt up, like from lugging the motor. Batteries do tend to perform more sluggish in colder temps and have greater voltage sag but a drop that high would be a surprise. You may also want to check how it is geared, and if there is any friction etc.. if the core is burnt up that's physical damage and not warrantied by any company but we can help you figure out what the cause is if that is not the issue, just email support
would these parts be compatible with the new cyclone motor stuff? than k you

Any idea when the BBSHD 68-73mm motors will be available? I would like to buy the whole kit including a battery. I have been waiting over a month, and I still haven't seen the kit pop up on your website. Am I missing something. Thank you, Dave

Hello, I am interested in the BBSHD engine - Bafang 52v. Is it possible to replace the display dedicated to EggRider, and will I buy it without a steel chain wheel - I have one in my home stock? The basic question is, will you send me everything to Poland, to Warsaw? - because it is the most important. greetings Cezary Dudzic

Hi there, I live in Canada, west coast. I have decided on a bbshd kit but want to know how to add the Bafang tool as well. I also would like advice on a battery for this kit. I do mainly city riding, lots of hills and occasional easy trails. Are these all in stock and is there duties to Canada.

Hi there Chris, we sell the luna wrench on this page https://lunacycle.com/parts/bafang-parts/bbshd-parts/copy-of-luna-wrench-bbshd-and-bbs02-mid-drive-installation-tool/ I would probably use the Wolf battery. Both because it is in stock and it is the safest battery on the market. But this would also work with common shark packs in 48v and 52v nominal voltages. As of today standard size bbshd is sold out, we do have the fatbike version in stock and should have more 68-73mm version within a few weeks. Yes there would be customs fees to import into your country.
Trying to order a BBSHD kit for a normal width. the page shows that option for a second then flashes and moves tot he two fat options only. What am I doing wrong? Have ordered one in the past and now looking to build a second bike.

Hi. If you mean you are comparing BBS02 to BBSHD, generally speaking if you have a fatbike you would want BBSHD as BBS02 is typically unlikely to fit fatbikes. Please check out this page https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/10736-how-to-order-the-right-bbsxx-kit

Dear LUNA Sales, I am interested in using the LUNA BBSHD kit with a Gates Carbon belt bike (Priority Classic Plus Cruiser - https://www.prioritybicycles.com/products/priorityclassic2?gclid=Cj0KCQjwoJX8BRCZARIsAEWBFMJkO-tfMgZjAzVFwogTyyhBVz8rQCjGGIHbBoXg83Rh3OWySZx_GUEaAufzEALw_wcB ). Could I get a Gates compatible front sprocket and spider to fit the Bafang BBSHD in place of the stock chainring normally supplied with the kit (which I would not be able to use)? I also am interested in monitoring motor temperature and current flowing through my Bafang motor. Do any of the display options provided permit readout while riding of motor temperature and operating current and power (operating voltage x operating current)? Thank you for your kind consideration of my questions.

Hello, big fan, I am looking to install this kit on a road bike for a 20 miles commute and had a question if there was drop bar brake style brake cut off switch or if the cut off switch on the bars in the optional section would be able to transfer to the drop bar brake set up? I Was also considering if the the derailer shifting sensor can be utilized where the front derailer (will be removed in install) used to be?
We will send a verification email to confirm your answer. All responses are subject to store approval.
Hi, depends on the kind of levers you have. Might be possible with drop bar brakes. TBH ebrakes are optional and not necessary. On many of our personal builds we do not use them. Regarding gear shifter, if you remove the front derailer then installing the gearsensor on that shift cable would be pointless as it would not be connected to anything. You want it to be installed on the rear shift cable.

I have some questions about ordering a BBSHD kit to put on a Surly Pugsley. I am not an experienced bike builder. If I can get these nailed down I can place my order. I would use the bike mostly on backcountry ATV roads, but also on some single track in Idaho. Main goal would be to access some trails and places that would otherwise entail a several mile hike just to get started. I am a heavier rider at about 200 lbs and may want to haul up camping and fishing gear as well. First question is whether or not you can program the controller for me before shipping. I am not interested in high top speed at all. I am interested in having better torque and hill-climbing. I also plan to pedal the bike a good bit on easy grades. I have read that the stock controller provides too much power in the low pedal assist modes, and that many people reprogram it to be a much more gradual increase. I don't have a windows computer and would rather not deal with the reprogramming if it can be done ahead of time. Next question is about the chain rings. Sounds like I would for sure want to upgrade that. Since I want more torque, the mini ring sound good, but I have read that going below 42T on the Pugsley may be a problem. Any thoughts on that? For 42T it sounds like the luna eclipse gives a better chain line. I'm a little confused on what to actually order. If I wan the eclipse do I order just the 2 things, the face and the sprocket - and not order the Luna aluminum chain ring adapter with 42T sprocket? Please let me know thoughts on this and I can get it ordered. Thanks! Todd

Hi Todd, torque relates more to how it is geared than how it is programmed. Regarding different profiles that is not something we can program, I think stock feels good but if you wish to change it just find someone with Windows PC. Sounds like you would want a smaller chainring. Yes the 42t eclipse sounds like it may be suitable. Will depend on your frame to some extent, might want some chainring spacers to go with just in case you need to space it back out, if it hits the chainstay. Regarding the eclipse yes you would order the face and sprocket. The 42t aluminum is a different chainring. Cheaper, but does not provide the same offset. For more info check out the documentation linked from the listing, it goes over all this in great detail!
What size are the cranks? Can the kit be ordered with 165mm cranks?
We will send a verification email to confirm your answer. All responses are subject to store approval.
Stock is a decent length, 175 I think. Kit can not be ordered with short cranks but there are various aftermarket cranks you can add that will work. For example you can get shimano steps e6000 cranks in 170 from various sources, or even unicycle cranks in much shorter lengths.
Will this kit work if my frame had a press fit BB with SRAM DUB cranks. The bike is a Intense AVC.

Possibly, but you would want to check out our documentation to be sure. Specifically this page, and this page.

Hello. I’m Michael. I’m planning on buying your Bafang BBSHD Mid Drive Ebike Kit 750w in 48v. I currently have a 48v 20ah lithium battery that states Grade A 18650 cells. That came with a 54.6v 2a charger. The battery is brand new and charged once. So my question is will this battery work with your kit? Also what is the cost of shipping to either Chandler, AZ 85225 or Mesa, AZ 82504. First location is my work and the other one is my home. Thank you for your time. Michael Wiley BTW I found your website a couple to few years ago. When I decided to go mid drive I knew that I would purchase it from you. I also own 80 acres of high desert land in northern AZ and look forward to this hot rod bike on my property and the surrounding areas. Thank you again for your time

Hello Michael, yes the battery will work that kit, though you might need to match connectors, which might involve soldering, crimping or using the solder sleeves available in our connector section if you are wanting a way to do it easily. To get a shipping estimate enter the items you would like into your cart and either use the link to estimate shipping from within cart, or enter your address into check out and it will provide a quote. Thank you for the kind words and I hope you enjoy the kit as much as we do.

You can add it to cart separately, sure. It is a bit cheaper that way. Here is the listing.
I didn't see separate box for controller? So, I'm assuming that controller is built-in and just need this motor and battery ?

Electrifying a Haro Subvert HT5 with a 73mm BB. Assuming the 123mmD in the manual is the gear reduction diameter, I estimate 11-12mm shim to avoid contacting the chain stay. Would you recommend I buy the 73-100mm BBSHD?

I have a mountain bike with a standard 73mm bb. At this time your HD kit is not available in the 68 to 73 mm option. Will the 73 to 100 kit work with extra spacers? And if so will I need more than one extra spacer kit and what will that do to the chainline?

Hi there, yes in theory it would work, but most folks tend to prefer standard size. See this page for considerations on how the kit would need to be used to make 100mm work with a standard size bottom bracket: https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/83401-mounting-100mm-bbshd-on-73mm-bike-frame-considerations
