Luna did their own unique design on the archaic Bafang Tool Kit to make it more affordable and more usable. The Bafang installation kit retailed for over $100 (we sold it for $65) and this tool we think is better at under $30.
Not only that because of its thin no-nonsense design, this tool is cheap and easy to ship in a flat rate envelope, making it more affordable especially for our international customers.
The only hard part about the Bafang BBSHD or BBS02 installation is you need a special wrench to install them. This tool has been custom machined out of stainless steel to make installing and tightening the inner and outer rings on the BBS02 and BBSHD easy. If you are an ebike shop you will probably want these tools so you won't have to risk scratching the paint on the units when installing them

This tool is nicely made and seems like a necessity to tighten the lock ring for the motor. Buy it with the kit for a discount.

high quality..good addition to your tool kit
The 4 point side needs to have offset , so if you flop it , you get more combination
Posted by scott M on Feb 12th 2017
The tool bottom out on frame and could not go back to the next cog, if it was off set you could flip the wrench to get more combination.

Good quality wrench that is two tools in one.
Glad to have it

Videos show installing the BBS02 with a "spanner" wrench. The spanner is generic, not a specific fit, has one tooth and does not appear strong enough to properly tighten the friction plate. Plus, spanner wrenches are just hard to find locally. I consider the Luna Wrench a must have for installing the BBS02.
Further, LunaCycle gets kudos for offering the wrench. Other e-bike kit websites that I've visited don't help you with this part of the installation process.

finally a tool i can pound with a rubber hammer because it snug fits : i added some loctite : now the bbshd has no more sagging.
had to unscrew them yesterday : even with the loctite it worked
This worked like a charm!

A necessary tool for installing your Bafang kit.
It saved me going to a bike store and spending $25.00 so it payed for itself
after the first use.
Tool works but so far only for temporary periods of time

I bought this wrench with my BBSHD kit, I already owned the BBS-02 kit installed on a different bike. The wrench was easier to tighten the kits than my modified channel locks but is tough to use due to the chain stay/ motor obstruction & sharp edges (def. recommend gloves or wrapping a towel around it while tightening). I can get the nuts somewhat tight but every couple weeks or so they seem to work loose & I have to re-tighten (my guess is this is due to not getting the right tightness on the inner nut due to the chain stay & motor creating odd tightening angles). Also, for those upset that "Luna" is not cut out of the wrench they received, this could be a blessing because my wrench (with cutout) started to "twist" on itself when I applied a lot of pressure to it so I believe the cutout actually makes the wrench weaker. Overall I would recommend getting the socket style tool set for the extra $5. Unfortunately I didn't see this kit before I ordered the wrench.
A must for BBS02 owners

It's a nice basic wrench with a cool "LUNA" cutout. I filed all of the sharp edges with a Dremel tool so that I didn't cut my hand on the sharp edges.

This is an inexpensive and effective tool for dealing with the weird lock rings on the BBSxx drive units. I wish I had it when I first did my build. If you're already spending nearly $1000 on a drive unit and battery pack, you might as well spend a little more and get the right tool instead of trying to adapt generic tools that may or may not fit right.
A few improvements would make this wrench great.

The first thing I felt when I removed this wrench from it's wrapper was the sharp edges along the handle of the wrench. I had to wear gloves or wrap the wrench in a cloth to keep from cutting my hands during use. In my application the chainstays hidered my ability to turn the wrench. I suggest the the wrench should have a slight angle where the handel meets the head. This would allow more clearance of the chainstays. The wrench handle bent very easily. I'd like to know what grade this Stainless Steel is. A much stronger grade is required. Overall, it did the job for me. I was a little dissapointed in the quality. I'd recommend the the Bafang socket style over this tool.
Works as advertised

Makes installing the lockrings easy
Posted by Brian on Sep 2nd 2016
This tool is almost perfect. It perfectly fit my BBS02, and I was tremendously happy I purchased this. I cranked down on the tool to get the inner lockring super tight, and the tool took the force without any flex.
As noted in other reviews, I can see how the orientation of the inner lockring tabs could be improved to allow less-than-90-degree rotation on frames that have trouble. I did not have this problem.
The one thing I did wish it had was a square cutout for a carriage bolt that could be installed along the main axis, allowing a bolt and nut to be installed for grabbing with a torque wrench. This would have given me the confidence that I'd definitely reached 70N-m on the inner ring.
The right tool for the job
Posted by Cindy on Aug 29th 2016
Sometimes you just can't get the job done without proper tools. The Bafang motors have a couple of odd fasteners, and this wrench fits them perfectly. If you're installing one or 100 of these motors, you're gonna need this tool.
I'm not impressed with the wrench!
Posted by Unknown on Aug 28th 2016
For $19.95 for one wrench I would have expected higher quality machining. Even though I had plenty of room it was difficult to fit it on the lock ring. I wish I had spent the extra money fro the Bafang tools. I'm sure they would have worked more effectively.

Would work better if the inner locking ring end were angled 10 to 15 degrees.
