Bafang BBSHD Review: Can You Handle The Power?

Reviews / Sunday, February 4th, 2018

Looking to grab yourself the COOLEST mid drive ebike motor huh? So of course you’re reading a Bafang BBSHD review to see if it’s really what you think it is?

Good call.

Hey, look, you can get the BBSHD right here!

I’ll tell ya.

It’s worth it. It’s everything you’ve ever wanted. And more!

This mid drive motor is made by Bafang, and often distributed as an “8fun” motor. They’re the same thing.

It’s a 1000w rated nominal power motor. That means it can continuously put out 1000W and work flawlessly forever.

The motor will peak at a higher wattage output when you hit the throttle. It can peak around 1500W!

It’s the successor to the hugely popular BBS02. The 750W, more petite version.

One of the best parts about the BBSHD is that it fits almost every bike frame.

The BBSHD simply fits through your existing bottom bracket. It comes with 68-73mm, 100mm and 120mm sizes.

So you can even put the BBSHD on your fat bike! This makes it insane for offroad, sand and snow applications.

So if you have a current bike, it’s likely that you can fit a BBSHD very easily.

You’ve only got to get yourself the motor and a battery. Then it’s all plug and play!

Bafang BBSHD Review: BBSHD motor mounted on ebike


Installing the BBSHD is very easy, even if you’ve done very little bike mechanics.

The kit comes with:

  • The motor (including integrated pedal assist sensor)
  • 2x eBrake levers
  • LCD display
  • All cables
  • 46 tooth chainring
  • Both cranks
  • Thumb throttle
  • Speed sensor
  • All required screws, bolts and nuts

So you have everything you need to get it installed, right in the box.

To install, all you need to do is remove your cranks, sprockets and unscrew your bottom bracket inserts.

To remove your cranks, you will need a crank puller. Seriously, get a crank puller or borrow one. I tried to get them off without it, and it’s not worth trying. You’ll probably break something.

Followed by sliding the BBSHD right through the bottom bracket, adding 3 nuts to the motor. One nut hold the motor upright. The next one holds the previous nut in place so the motor cannot slip down. This nut needs to be tightened as hard as you can – Bafang also sell a tool to do this, but I found that an adjustable wrench also worked.

The last nut is to stop anything from undoing itself. This is only aluminium, so don’t tighten too hard or you’ll strip the threads.

Next it’s just wiring up the battery and the ebrakes, display and speed sensor.

Some of the parts however, are less than ideal.

Most notably is the stock 46 tooth chainring.

Bafang really didn’t care about how their chainring performed in the wild.

It’s utterly terrible and I wouldn’t wish it upon my worst enemy.

Now don’t get me wrong, it “works”, but not well.

I’ve found that if you go over any bumpy surfaces without putting the chain under tension, it derails.

In my experience, “any bumpy surfaces” includes tree roots, cracked sidewalks and going over curbs.

I’ve had days where I had to put my chain back on every 5 minutes.

Please don’t torture yourself like I did. Get a Lekkie Bling Ring HD as part of your build. It has narrow/wide teeth to stop the chain coming off. And it does a damn good job of it too.

It’s such a worthwhile investment. You’ll never look back!

Build Quality

The BSSHD is one huge beast. It weighs in at just under 13lbs (5.9kg).

It sports a huge array of beefy cooling fins around the motor casing. Making this thing almost impossible to overheat.

I’ve never had an issue with it. Even climbing 10-15 degree slopes at 13mph (21kmh) it’s never gotten too hot.

Bafang have over-engineered this beast to handle absolutely everything you could ever throw at it.

The motor is built to take much more than the 30A that it is limited to. In fact, Luna Cycle sell controllers that can handle 60A and up to 72V like this one here!

That will rock your socks off. Big time.

But for the rest of us who just want to plug and play with the BBSHD. You’re also in for a treat.

With a continuous amp rating of 30A and a peak of around 40A on the stock controller, you should be able to power along with 2352W on a freshly charged 52V battery – hot damn!

If you swapped out the stock controller with Luna Cycle’s one, with 60A and a fresh 52V battery – 3528W could be your peak output!

That’s enough juice to make a smoothie.

And probably to give you a wheelie and a sweet concussion.

Your mileage may vary.

In any case, this thing is a damn beast and you’re going to have fun on it.

I only have the stock controller and I’m still loving it!

The BBSHD also has IP65 enclosure rating which translates to completely dust proof, and waterproof from low pressure water jets from any direction. So it’s water resistant for outdoor use. But don’t use your BBSHD for submarine applications.

All of the connectors are waterproof also. They give a satisfying popping noise when you unplug them.

So if you enjoy riding in the rain, or snow, or sand, or anything that makes biking really fun. Then you’re going to find the BBSHD a great companion, because you won’t be able to kill it with sand and water.

Unless you sandblast it. That might kill it. Feel free to test it and let me know your findings.

How It Rides

This thing rides awesomely. With a few caution areas.

My main gripe with this motor is the pedal assist (PAS).

I knew what I was getting into when I bought it. And it’s not all bad! But it does take some getting used to.

If you’ve ever ridden a bicycle, and I’m sure you have, you’ll know what it feels like to pedal.

You know, you apply pressure in a rotating motion and you feel resistance of all the parts working. Yeah, that’s the one.

Well it’s different with pedal assist from the BBSHD. Pedal assist is where the motor knows you’re pedalling and gives you a little help in the form of electrical power!

You’d think that as you pedal, you feel resistance and you get a little help.

Not quite.

You have a range of pedal assist levels. It can be 0-3, 0-5 or 0-9. I recommend 0-9 for more fine tuned control.

If you start pedalling, the BBSHD gives power up to a certain threshold which is determined by the PAS level.

PAS 9 will give you almost full power of the motor as soon as you start turning the cranks.

So as soon as you’re pedalling, you’re speeding off!

In my 1st gear and PAS 9, I start pedalling and get to about 20mph (32kmh) without actually putting in any effort. The motor does all the work.

I can get up to 40mph (65kmh) in 8th gear, full throttle and some pedalling too. Way too sketchy for my liking to do all the time, but fun on occasion. Plus this is using my knobbly mountain bike tyres. If you try this on a road bike, you’ll be going quick enough to outrun a cheetah!

This can feel a little unnatural to someone who is used to riding normal bikes. As the motor spins the front chainring faster than you can comfortably pedal (usually). So you’ll be spinning the cranks, but your energy doesn’t really do anything. At all.

This is good news for those who want to commute to work without getting sweaty! I often just use PAS 9 when in my work outfit and turn up to the office without any stinky, sweaty clothes on.

Alternatively you can lower the PAS level to find where you can comfortably pedal and have decent speed. I like the speed too much, so I almost always use PAS 9 or full throttle.

That’s the other thing too! You can simply use the throttle and not pedal at all. You get great looks when you’re not pedalling and cruising uphill at 13mph (21kmh).

Where To Get One?

There’s a few places you can grab yourself a BBSHD.

You can grab a BBSHD online. (This is where I ordered mine!)

Or alternatively you can order one from a seller such as LunaCycle.

Online is your best bet if you’re outside the U.S.

However, some local stores in your area may carry the Bafang BBSHD too. So it pays to ask around!

Bafang BBSHD Review: The Verdict

The Bafang BBSHD is one hell of a step up from the BBS02 of yesterday (metaphorically).

It’s beefy enough to handle steep inclines. It has upgradability potential. It comes with everything you need. Apart from that stupid chainring – get a new one!

You can pair up this bad boy with a 48V or 52V battery with the stock controller. If you like power, you can upgrade your controller and get a 72V battery to really up the ante. And the risk of injury and/or death. Probably.

If you’re looking for an ebike battery, check out my guide here.

It can handle hills with ease and glide effortlessly and quickly across the flat.

If you need more convincing about the BBSHD, check out some videos about it. You won’t be disappointed.

I’ll see you cruising around town on your new BBSHD.

Ride fast and arrive in style.

    1. Hey Matt,

      Thanks so much for checking out my blog!

      A fatbike with a BBSHD sounds like the best idea for all year commuting in snow and ice. You’re off to a good start!

      My other recommendations would be mudguards (unless you enjoy road grime spraying in you me face), definitely lights, and also I’d get the biggest battery you can afford, cause it would suck being stuck out in the cold if you forgot to charge it one day, or something happened!

      Check out my article on some of the best accessories to get some other ideas for your ride (

      If you’ve got any other questions, feel free to ask me 🙂

      Send me some photos when you’re done building, I’d love to check it out!


      1. Thanks Zade!

        How do you think the BBSHD will handle in the snow? If I rarely take it on trails, what size chainring would you recommend?


        1. In the snow, with a BBSHD – easy stuff! Should be able to plow through easily.

          Rarely on the trails, but still in the snow and muck… Hmm, I’d be looking for something like 38 – 34 teeth. If you want to go a little faster, I’d go for 38 or even 42 tooth if you weren’t going to be going through much snow.

          For some serious snow and serious power, 34 is gonna see you through!

          If you have the time, money and inclination too – try a few out. A 34 and a 38 tooth would give you a good gauge on what you want to use mostly.


    2. Go to electric bike blog and look at Karl’s sooner tire solutions, including studs. Remember the battery will hold less power in cold weather (“there was shrinkage!”)

  1. Zade,
    Any recommendations on how or whether to use electric assist on a tandem?

    Are there features on a tandem that make the bike more or less suited to electric assist? For example, we have a 1980s Cannondale aluminum tandem that we love to ride, but it is limited to a six gear cassette on the rear wheel due to bomb proof Phil Wood hubs, and it uses the older 27 inch tires.

      1. Hi
        I have an older bike (15r)but was composed of quality components
        which can go wrong most often ?
        which is most often damaged during this reconstruction?


  2. Hi Zade, good article and I’m in agreement… my BBSHD rocks! I’ve rigged up a Surly Pug Ops fatbike to a BBSHD with a rear Rohloff internal gear hub. The range of gears and power is apocalypse worthy and I can get so low that I could practically cycle up a vertical wall a la Spider-Man!

    Snow is good… but only in low power otherwise you just spin out. Packed sand…. fat bike speed demon. I find that running at PAS2 out of 9 with a 52v 26a battery can get me about 60 – 100 miles easily depending on gradients and technicality. And that’s still as fast as my buddy going at 15mph average on a standard non electric mountain bike.

    I have a standard BBS02 500w on my Straggler light touring \ commuting bike which is more than enough for a 20mph commute to work (and I’m a heavy rider) or a low PAS tour.

    Thinking about putting another BBSHD on my Krampus 29+ with my third Rohloff and a Rockshox Pike RCT3 fork. This would be mind blowing… just wish I had the money to finish that build now…. Another Rohloff, front boost hub and Velocity Dually rims…bankrupted by bikes 😂

    1. Hey John, you’re absolutely rocking it with your ebike game! I love it!

      I’m more of a road speed freak myself, but I’m definitely wanting to get into some trail riding and sand fun soon.

      Thanks for your comment, really appreciate it. Keep on killing it my man!


      P.S. Can totally empathise with your “bankrupted by bikes” statement 😅

    1. Hey Wendy, I’m in the UK and an old hand at this home conversion stuff. I can help talk you through it step by step. And show you how to do it cheaper than all these places charging to convert it for you! Zade, are you able to pass on my email without it going public? Peace all ✌️

  3. Great article, I am researching mid drive and hub motors to install on a couple of recumbent trikes. Yesterday I ran across a long article that was less than complimentary regarding the bbso2 A and B. The article claimed that Bafang redesigned the A version with out saying any thing to any body, in particular dealers. It also said that Bafang does not support the A model with repair parts and that the two models are completely different and the components are not interchangeable. That said, have you heard anything along these lines.

    1. Hey William,

      Thanks for reading my blog.

      Can’t say that I have heard much about that actually, but it could well be true.

      I don’t normally recommend the BBS02 as the BBSHD is significantly better in the way that it is designed. But I have heard of issues with nylon rings inside the motors that can warp under some heat and stress of hard biking (or just general abuse). So you should be alright if you ride normally and within limits.


  4. Thanks for all the info , i am trying to put together the best pairing of motor and battery to propel my large mass (260 LBS) up inclines of 15 percent for up to 2 miles thoughts? My average ride in th mountains is 15 to 20 miles

    1. Hey Chris,

      Thanks for reading.

      I’d be going for as much juice in my battery as possible and lower that chainring size down (I have an article on chainring sizing which might help you out!)

  5. Hey Marc, I am confused because your saying that the BBS03 is the successor to the BBS02, but then your site starts talking about the BBSHD kit. I contacted Lunacycle and the man there said that I could program the BBS02 with a data cable to computer as to giving the BBS02 more power. Is this true or perhaps I heard the man wrong and it is The BBS03 that can be programmed to deferent levels of power. By the way I have a new GT passage aluminum bike with a 1”1/2
    half inch Round sprocket were the shaft slides in. And it’s 2”7/8 wide/almost 3” inches, Will this work for me.

  6. Big problem is the motor drops down and slams up. A screw clamp fixes this. I’d send you a photo of my setup. I have 42/11 and 27.5 it hits 40 also. Wheelie in the 40 52 volt battery and that is also clamped down. What is the best way to mount the battery for extreme mtb riding? I’m totally stoked to buy the mongoose envoy when available and get rid of current rig.

  7. I have an older model RANS Stratus LE recumbent. It has a 68mm bottom bracket and has FSA English threads. Will the BBSHD work on my bike? Also, I would need to have the battery on a back-rack. What battery will give me long life and long mileage?

  8. interested in a BBSHD assist motor . can these motors be purchased as a direct motor mount to a motor plate and be direct drive with a chain to rear hub . would like to stay away from mounting in the bottom bracket.
