 BBS02 Listing
  • Drive, battery, charger combo...everything you need minus bike.
  • Our lowest price ever on a BBS02 and wolf battery combo
  • Perfect if you have another bike to build out for a companion rider

When we first created our sell direct website Luna Cycle in July of 2015 the going price for the BBS02 was $1100 by sellers who would try to convince buyers that their BBS02 was different from the next guys.  The BBS02 is still the same as it has always been two years later but now the price has fallen dramatically.

The going rate for a 700 watt hour Panasonic battery was over $1500. 

We are offering an amazing price on a conversion kit with everything you need to convert almost any bike to an electric. Please share with your non-powered friends and your slow electric bike friends.

And now it has a significantly lower price than the BBSHD making it accessible to almost anyone, at this limited low price it makes a lot of sense over the BBSHD.

This mid drive has many advantages over a hub motor kit. And at this amazing price a hub motor kit makes little sense.

  • Allows you to use your bicycle gear train
  • Easy to install (watch install video)
  • Gives you perfect weight balance since it is low and centered
  • Silent
  • Reliable
  • Plug and play

Please note this kit does require installation and installation will require you spend some time on our technical forums and on our youtube channel, because each bike has its quirks and installs can be a bit tricky the first time. 

Regarding Controller and Firmware Hot Rod

Our kit includes a factory hot rodded controller different than most BBS02s purchased from China. The original BBS02 controller also had weak mosfets that would blow out easily when too much load was put on the system. We have had all our drives modified at the factory with more expensive and robust 3077 mosfets to make the controller handle more power without overheating. This makes it possible for us to change the firmware to a set up that allows you to utilize all peak 1300 watts this drive is capable of. We still recommend that you use a lot of common sense and keep your motor spinning fast by shifting down and keep your motor revving high when climbing. All electric motors prefer to spin at high rpms and you should keep this in mind and baby your Bafang. We do not cover blown controllers under warranty. So if you overheat your controller by not following our operation guide, you will have to replace it. 

The way this kit comes from the manufacturer it is very solid and hard to burn out. It is also difficult to get the kit’s maximum 1300 watts of performance which you can do by upgrading the firmware. We sell our kits to experienced builders with the firmware already upgraded. (Click here for the firmware programming guide)

We recommend you get the optional programming cable so you can tweak your own program settings. Their are many online guides which will help you do 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 derailleur if you have one. 

Your donor bike must have 68-73mm bottom bracket width. That means this kit will bolt onto almost any bicycle, but not fat bikes or bikes with bottom brackets over 74mm. We have the BBSHD which is 1000W nominal 1500W peak and will work with fat bikes 100-120mm bottom brackets (BBSHD located here).

We include special mounting hardware for 73mm BB. If you need this and it was not included let us know and we will send separately.

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 else's building steps.

Here is a post on our builders forum with a picture  collection with links to  build reports you can quickly 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 $45 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.
