Battle of the Bafang BBSHD Chain Rings

The middrive Bafang  BBSHD  1000W kit is taking shape to be one of the hottest ebike kits of 2016 (as we expected). It is powerful, silent, reliable, efficient and it is a middrive. It is the predecessor of the tremendously popular 750W BBS02 with more amps and 10 percent more efficient, which all translates into more  power. Plus the BBSHD 1000W has had every piece re-engineered to be more robust to put up with the extra power.

Lunacycles is currently doing a Chinese New Year Sale on the Bafang BBSHD for $699 with a  one year warranty.

There have only been some minor complaints of the BBSHD.  It is three pounds heavier than the BBS02.  Its stock chaining is brutally ugly.  The Stock chain ring comes with 46 teeth, and it seems to be geared too high at this gear ratio…especially for riding off road.  The BBSHD needs an offset to make a straight chain line…and the stock chain ring does not offset enough…which makes chain alignment issues with some installations.

This thing looks like an ugly frisbee. It feels like a lead weight.

Take a look at its offset…it does the trick in an ugly and heavy way….not cool on an $800 dollar drive system ($1100 if you buy it from the wrong seller)

There is an easy fix for all these problems…aftermarket chain rings made up of cutting edge hardened aluminum alloy can shave up to a full pound off the stock chain ring…and are made in blingy aluminum that looks awesome,  and they all have fewer teeth than the stock unit to improve the gear ratio of the BBSHD (all electric motors like to spin fast). In the case of the Luna Eclipse chainring, it has more offset than stock, improving the chain line.

So lets take a look at all the available chain rings, and the links to full reviews on each one. Since our friend Karl at electric-fatbike.com has already written complete reviews of the chain rings on his site, there will be no need for me to go into any more details here. By the way, Karl’s website is shaping up to be a powerhouse of information for the mid drive DIY community and is developing a cult following…him and his orange hair. Whatever, he deserves it.

Anyway, back to the battle of the chainrings.

Last year there was only one custom chain ring on the market for Bafang products and that was the Lekkie Bling Ring for the BBS02. This year is shaping up fast for the new BBSHD, and there are some exciting offerings just a month after the release of the BBSHD.

Our sister company Lunacycle.com was first to the market this year, not only with the BBSHD kit itself (first dealer in the world to have in stock) but also the first to provide an upgraded chain ring…The Luna Eclipse.

The Luna Eclipse is a 2 piece design, coming with a 42 teeth, but also with the feature of being able to switch to different tooth-counts in the near future. The Eclipse uses a wicked tooth profile to ensure that the chain stays on even on full suspension bikes. The Luna Eclipse retails for $98.

Lekkie was next with their BBSHD 42 tooth ring. This is a one piece design which uses their tried and true chain tooth profile.  This chaining retails for $110

Good competition invites innovation…. and a 3rd chain ring was recently announced.

Luna Cycle is now offering a 30 tooth gear dubbed the “Mighty Mini” which totally changes the characteristics of the BBSHD, transforming  it into a torque monster.  This chain ring retails for $55.

Wow…3 awesome cute-looking  chainrings for new BBSHD owners to choose from…good times! One of them is tinier and cuter than the others…sort of like a cute puppy or kitten.

    Re: ‘ Mighty Mini’…I have never seen a chainring with such long teeth before.

    Why not make an adapter to be able to use a normal 4 arm/104BCD chainring?

    I only use ‘Surly Stainless Steel chainrings’ because why use ALU chainrings in a system that has a STEEL chain and STEEL cogs/sprockets…(the ALU rings wears the fastest and wears out the chain which wears out the cogs/sprockets…)

    • Wake and Vape

      Because making an adapter is way too easy….. and its not the perfect solution….it forces you to over pay for an overpriced race face chain ring…. we tried to make the perfect solution with the eclipse. It is basically a glorified adaptor if you think about it….we will be releasing different outer rings for it. All the other guys can do the old schools adaptors and if we decide to do one it will take us 1 day to make it. We decided to make the Eclipse not because it was easy but because it was hard.

      • Al

        I can see now that there isn’t much room to put a ‘normal’ 4 or 5 arm chain ring on an adapter anyway…(especially if one runs a 40 tooth like me for off road ground clearance).

        But I was talking from an engineering perspective (and relating to motorcycles and car’s) when I was referring to ‘Steel’ sprockets:

        ‘Did you notice that ALL drive train components on cars and motorcycling are made out of ‘steel’?
        (The only exception is for the back sprocket in Motorcycle Racing…where durability and longevity is sacrificed for weight).

        All the best motorcycle sprockets are available in Steel and Alu….the Alu ones are for racing and the Steel ones are for everything else…

        Now the best of the best have a Alu core and Steel teeth…
        See: ‘Supersprox’ Stealth sprocket or ‘Renthal Twin Rings’…

        Or check out ‘Ironman Rear sprocket’ to see how light ( and strong) a sprocket made out of (not made in China) Steel can be made..

        Did you know that Steel sprockets last 3 times longer than Alu ones…(but of course are up to 70% heavier unless its a ‘Ironman Steel sprocket which is only 30% heavier!)

        Did you know that all this is common knowledge in motorcycling circles?

        • Electric Bike

          we consider our stuff bicycle stuff and in the bicycle industry Aluminum alloy is king ….light weight does make a difference

          • Al

            Thanks man…you convinced me there and inspired me…and you know what?..I am gonna make a drive chain out of ALU!!!…I don’t know why nobody else has thought about it before…
            I am gonna make a fortune…and they all gonna say: ‘why didn’t I think of that…it was soooo obvious?’

          You are wasting your time discussing this with Eric, he doesn’t really do engineering, or have more than a vague idea what he’s talking about. Telling a designer or manufacturer roughly what you want, isn’t quite the same as actually designing and developing something from scratch… don’t tell Eric this 😉

          He’s more about revolutions (gives it real meaning, so you know your doing something good and life changing when you buy your Luna parts), reasonable prices (not cheap and it suggests that anyone more expensive is unreasonably priced) and hot rodding (not entirely sure what this means in some situations, but it sounds cool and impresses the kids).

          • Al

            Yeah mate…good analysing!

    The Lekkie is a far superior product, i don’t know why you bother. If you can’t add something, leave it to the people that can. Eric you should speak to your supplier about their design and the finish, it isn’t the best.

    The Luna chainwheels are no more yours, than they are mine. You just buy them from someone and get your logo added. Go easy on the BS, it gets boring….

    • Electric Bike

      lol we just got 70 lekkie chain rings from the lekkie supplier in China…..and they were all 1mm off ….we had to have our machinest bore them out. The screen printing was off etc. There is no comparison to our ring and the Lekkie ring…the annodizing the finish..the design..the level of qualty …sorry. .. you are way off. You are purely talking out of your ass “peter”

        Nice!
