(BBSHD mid-drive motor shown with Eclipse ring gear attached.)

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

The stock 30A peak power setting for this drive drive is capable of a whopping 1500 watts in the right circumstances, and we offer Ludicrous upgrade to an even higher power controller if you prefer. If you want your drive to be programmed for lower power 750w street legal use leave an order comment in checkout requesting this.

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.

Our BBSHD kits come with a spacer kit which is enough for most conversions. 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 kit comes pre-equipped with a 52v Wolf Battery, however you do have a choice in the capacity and type of cell that comes with it. 

The Samsung 30q is a great cell known for it's high discharge rate and good range, while the LG M-J1 is a newer cell that offer both the highest energy density and fairly good continuous discharge. According to our sources and test the MJ1 is slightly higher discharge performance than the GA cell.

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 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.

ChainRing 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.

The Luna One 40T 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 find this size a good middle ground between high climbing 30T and street shredding 46T +. 

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)

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 Wrench 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 normally now on sale for only $15.  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.
