One of the biggest criticisms of the BBSHD is the ugly and heavy steel sprocket. Luna Mate now has an exclusive 42 tooth narrow wide Auluminium chainring. We include that stock sprocket in case you want the higher gear reduction. Motor with battery needs to be selected. This chainring had 21mms of offset.
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 being 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 now also made in odd sizes (72mm & 120mm), including extra fat. We include a spacer kit with every motor so your BBSHD will fit almost any bottom bracket. If you are not sure then please call for support. If the incorrect motor is ordered, then I will exchange the motor provided the customer pays for all postage.
Install it on anything and ride it anywhere. With the proper gearing the BBSHD will easily climb stairs, go well over 50kph 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) 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, 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.
We are shipping it with the controller programmed, so not only can you get pedal assist when you want, you can also get full throttle when you want it.
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.
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 one spacer kit good for 10mm total, if using a 100mm fat bike motor on a regular bike (73mm) some additional spacers may be needed. Please include a comment at checkout if more spacers are required. (If possible we recommend using the correct motor for your bike for the best possible chainline in order to prevent chain derailment)
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 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 compatable 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 collection of build reports you can scroll through.
A well designed and simple conversion kit. Fit onto my 68mm and 73mm bottom brackets with no issues. Plug-and-play installation, took less than 3h to convert bike at home with basic tools. Came with a 42t Luna front chainring, which is very good. Almost perfect chain line on my 11-46t cassette, shifts well. Performance is great, extremely torquey, bike will flip over or lose traction before the motor stalls in low gears. Much faster than any store-bought e bike I have encountered. Pulls 1500W on 52v with throttle, could possibly get more by changing settings. Is also extremely quiet for such a powerful drive, chain and tyre noise is louder than the motor. Beware that as a conversion kit it is not guaranteed to fit all bikes, and bottom bracket design and chainstay width needs to be carefully considered. Fits well on my 2020 merida big nine.
