This listing is for the drive unit only which includes ONLY the following:

BBSHD 750w Motor with Built in Controller

Stock 46t steel sprocket

This is all you need if you are upgrading your old BBS01 or BBS02.

Unsure if you need to replace the black triangular mounting plate that was on your BBS02?  If you have version "A" BBS02 you need the plate however you will not need this part if you have a late-model BBS02.

The BBSHD is completely redesigned predecessor of the BBS02 but all the accessories, crank arms, wiring harness, display, throttle, ebrake levers are all the same. Luna Cycle takes advantage of this and offers everything a BBS01, BBS02 or E-rad user needs to upgrade to the BBSHD which is drive unit, controller and sprocket.  Even the old mounting hardware will work.

Even though you probably wont need it we recommend you get the  optional  mounting parts  kit option which will also include all the mounting hardware and out custom set of BBSHD spacers to ensure a perfect fit in case you need to line up the motor to clear an intrusive chainstay.

The BBSHD is the new 750w unit from Bafang that is both more efficient and much more powerful than its little brother the BBS02.  Also the BBSHD has proven itself to be reliable even at high power levels, in situation where the BBS02 can be more delicate (like climbing steep hills in too low of a gear).  Luna Cycles is offering a bare bones BBSHD drive and controller for people who have BBS02, BBS01 and E-rad and want to upgrade to the BBSHD.  Since all the parts are interchangeable you can easily swap out any of these drive system in 20 minutes and have a BBSHD with all the power benefits. The BBS02 had serious issues running for sustained periods at peak power, but this is not a problem with the BBSHD. We have tested it extensively running it at the full 1500W even on very long hills and we cannot burn out this motor. If you look at it from a certain point of view you are essentially DOUBLING your power as the BBS02 could really only put out 750W indefinitely or on long hills and the BBSHD can put out 1500W all day long without breaking a sweat.

Also this is an affordable way to upgrade to a fat bike  if you have a BBS02 now instead of buying an overpriced $600 kit to make your BBS02 fat (the kit consists of just a bottom bracket and spacers).  This price is good for regular sized bottom bracket bikes as well as fat bikes. 

This is all you need to swap out your aging BBS01 BBS02 or E-Rad BBS02 with the latest and greatest drive unit from Bafang, the BBSHD 750w. 

The gear sensor plug is the yellow HIGO plug and will work with the Lectric Cycles E-Rad gear sensor.

This kit DOES NOT include the full BBSHD kit with ebrakes, display, crankarms and cabling. It comes ONLY with the drive unit and the chainwheel and possibly the optional fit kit. (for complete kit click here)

I found a problem with a tandem which I had converted with a Luna mid drive on Thursday afternoon. Not knowing the immediate fix, I ordered a motor/controller the next day. I am located in Florida and knowing that the tandem couple needed a quick fix [they are training for Coast to Coast], I made contact will Kelly at Luna to try and get a quick delivery of the needed part. She responded by doing all she could to get my order packaged and ready for shipment but could not promise when the shipper would make the pickup. As luck and excellent service from Luna would have was picked up by the shipper on Friday. As I tracked the package over the weekend and the MLK holiday, it was scheduled to be delivered on Wednesday afternoon. Much to my surprise it was delivered this afternoon [Tuesday] at 3 pm. This was one day earlier than expected. I could not be happier with the attention that Luna and their order/shipping department extended in getting this critical part to me...and the tandem couple is elated with the service from Luna to our mid Florida town. This is the 5th tandem that I have finished for teams in the area and the first problem. Now that thing have settled down, I can locate the problem in the original motor. A great big Thank You to Luna and their staff.

Awesome Custom Option

If you are going to trick out your install this is a great option; but be sure to do your homework here.
You are going to need a few things ordered separate with this such as a wiring harness, a mounting triangle, mounting bolts and possibly spacers for the bolts, bottom bracket spacers, brake sensors, a speedometer sensor, maybe a shift sensor and an Anderson to cycle-90 adapter, and a display.
I don’t like the stock steel chain ring and already had a Luna Eclipse setup for this build; so I wish I could have chosen No chain ring as I ended up just tossing that stock ring.
