When we first created our sale 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 $1000. 

In fact this same combination we are offering for $750 to celebrate our 2 year anniversary some sellers still sale today for over $2000.

For a limited time we are celebrating our 2 year anniversary by offering the best deal we have ever offered on  the bbs02 drive system with Panasonic GA battery.


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.

The BBS02 is all that most riders need.

It has several critical advantages over its popular big brother the BBSHD  


  • It is 3 pounds lighter than the BBSHD

  • It totally falls within federal legal limits of an Ebike

  • It's smaller in size than the BBSHD which means more stealthy

  • It has more custom chainring options available

  • It has been around longer so it is a proven platform

  • Lower amps means longer range


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.

  • It allows you to use your bicycle gear train

  • It is easy to install (watch install video)

  • It gives you perfect weight balance since it is low and centered

  • It is silent

  • It is reliable

  • It is 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. 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.

48v Panasonic GA Shark Battery 


This Kit includes our tremendously popular 48v Shark Panasonic Ga Battery 13.5ah.   Read more about this battery here.

Which Options?

When you buy your drive the following info will help you pick which options are right for your bike.

Display Options

The displays are our ebike dashboard and all of them 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. 

C961 (Included) Classic Bafang display with basic vital information. 

750C is a Luna Custom full color horizontal display (read more here) that is a $45 upgrade option.  If you want the fanciest best looking display this is it.

Sprocket Options:

We offer the Bafang with 3 different options for tooth count on the chain ring.

46/48/52 tooth

Of course your gearing will also be determined by the rear cluster on the back of your bike. 

But you need to choose which of these 3 options you want up front.

46 tooth will give you the most reliable set up that is also very powerful and better for off road hill climbing.

48 tooth will give you the middle ground.

52 tooth will give you the highest top speed (30mph) but is only recommended for street riding and you should really take care not to overheat your controller when running this high by keeping your motor spending fast. 

(Click here to read our special care & instructions guide here)


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. 


Throttle options

If you are not sure about this one then 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.


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 BBS02 online. 


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 $19 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.

  1. I bought my mide drive from china before I knew about Luna cycles.

    Posted by Eric Stull on Jul 19th 2017

    I would buy my next mid- drive made in America from Luna Cycle ,what a great deal for 750$ ,buy it ,it's a great add on to your bicycle,I live in Pittsburgh on the highest hill and I ride into the city and back through the park, up some really steep hills 30 to 40% grade ,this motor climbs big time. I bought mine 2 years ago from china, 800 miles of no pedaling the shark 48volt battery pack is still working like a champ.I am so happy with the BBs02 ,750 watt motor on a cruiser with 26 inch rims I can go anywhere ,from trails with huge hills. I recommend you buy this set up that uses all your gears.mid drives rock.
