  • One of the most affordable Haibikes in the line, available in four frame sizes, relatively lightweight, large 29er tires provide float and momentum at speed for cross country riding
  • Very capable mid-drive system (the same motor and battery as some higher-priced Haibike models), zero cadence assist feels responsive from starts and climbing
  • Powerful 180 mm hydraulic disc brakes for handling the increased weight, capable 100 mm suspension fork with compression adjust lockout, Shimano Acera 9-Speed derailleur
  • The charger is bulky and heavy but offers faster 4 Amp power flow, Fixed display offers fewer readouts but is actually very capable (battery percentage, range, etc.)

Written Review

The HardNine 4.0 is one of a few entry level price point electric bikes from Haibike. With some scaled down mechanical components, and even a slightly scaled down electric system, this bike offer an excellent value in total. At $2,599 for a brand name production mid drive by Yamaha, warranty and all, it can be pretty tough to pass up for a budget minded cyclist looking to experiment with road or off-road pedelec riding. The HardNine 4.0 is a great bike anyway, offering a lot of bike (electronics aside) that doesn’t make any safety compromises. Brakes, shifters, frame, fork, tires; all up to par for most uses. While this is a lower-end Haibike, it shouldn’t be confused with a lower end bike from other companies. The HardNine 4.0 already has a much higher component grade than where other bike companies cap out.

Despite the lower entry price for the bike, the 4.0 still includes the same 250 watt Yamaha PW motor that all the other SDURO bikes use. Personally I really enjoy this motor on the road, as the 20 mph cut-off isn’t harsh. On the trails, it really hold its own against competing e-bike systems. The motor is cased with a protective plate that prevents impact from off-road obstacles, which is pretty nice for heavy use. Another great feature of the Yamaha motor is the ability to add multiple cogs to the front chainring. This particular bike only has one chain ring up front, but in other 5.0 models this feature is utilized. Although the motor is rated for 250 watts, the power output can easily keep up with, if not slightly out-do other 350 watt motors in the same category. The peak output of this motor can reach up to 500 watts and it offers 80 Newton meters of torque which is what I consider to be one of the most important considerations for climbing. I find it to be less noisy myself, but it’s hard to objectively measure how much motor noise the rider will experience. It’s going to increase as you raise the power level and pedaling RPM.

What is called the 400 watt hour pack technically holds 417 wh. The 36 volt 11.6 amp hour pack comes standard on this, and many other Yamaha powered bikes and offers above average range. On a personal road test we did from our shop, we encountered 31.4 miles of range on full blast pedal assist, until the battery died. Toning down the assist a little will increase the range, as pedaling the bike will reduce draw on the battery. Rather than clicking the battery pack down into a mount on the downtube like a lot of other e-bike modesl, the Yamaha pack slides in from the side and this allows for a lower top tube. The side swing battery may seem less robust, but the locking mechanism is strong enough to keep it on the frame without rattling. The battery has a loop on the top of the unit, which is nice for carrying around, but tough to stuff in certain bags or panniers on account of the length. Also, in my opinion, the charger for the Yamaha system isn’t the greatest. It charges just fine, but the cords are permanently connected to the rectifier, meaning that a fault in one of the cords would necessitate and entire replacement. Also, the battery terminal uses a clip feature to secure the charger to the battery, and requires the user to detach the terminal only 1/2 an inch from the battery itself. Pulling the charger cable may inadvertently yank the battery around or tip the bike.

The more basic Yamaha display mentioned earlier is an LED design, as opposed to their LCD display found on most other bikes. It’s mounted near the left grip, is backlit and has 5 buttons, 7 indicator lights and a 2 digit number readout. The read outs don’t provide as much information; it scrolls between 3 metrics: MPH, Battery Percentage, and estimated miles left. The left side assist up and down is pretty simple, though the display only indicates 3 levels of assist: ECO, STD, and HIGH. Haibike’s website claims a 4th level of ECO+, but this is likely a typo from the other LCD system. The display won’t show more typical things found on eBike LCD displays, such as an odometer, trip set, clock, timer, or power output. In my opinion, this display is a good way to save a few bucks on the overall price, but personally I enjoy the larger read out, and especially the odometer. Having this information on hand is very useful when relaying any electrical issues, personal range estimates, mapping progress and more. I also appreciate having the ability to remove the fancier display, especially when riding to a public rack or in a steep precarious downhill section where the bike could get dropped in a fall.

As a bicycle, the HardNine 4.0 is phenomenal for the price. It holds a brand name mid-drive system, that only compromises on the display. Also, the mechanical system is perfectly acceptable for an eBike in this price range. The hydraulic disc brakes work fast and bite hard, and the front shock is enough to handle obstacles on a moderate off-road ride. The 9-speed gear set doesn’t have the refinement, speed, durability or weight that a higher component level carries, but it’s enough to get going for a still-new bargain price. This bike excels in the hands of a casual rider, going off road in lighter trails. In less rocky cases like this, the 29 wheels can overcome obstacles fairly well, and the gearing has enough of a range to move through many inclines and a little bit of downhill. Steep uphill or hairy downhill will showcase the weaknesses of the bike, and will likely feel too big and stiff to handle. The bike will certainly operate just fine, but the rider will need a fair amount of balance and skill to overcome the higher frame (on account of the wheels) and the weight/rigidity of the frame. This is where 27.5″ wheels, full suspension, and seat post droppers begin to shine and when you’d be better off upgrading or switching platforms for all-mountain or trail use.

With little exception, it’s pretty easy to recommend this bike to someone who has looked it over and is still considering it. You get a lot of bike for the money. With most Haibikes, the sky is the limit and the rider may not utilize the higher component level. With the HardNine 4.0, the rider can easily see where the line is between performance and price. This is very nice for the budget conscience who don’t want to spend money on something they won’t use. My only gripes are the display, and the pedals. The plastic pedals will last for awhile, but may eventually break. Depending on use or behavior I’ve seen pedals like this brake from 300 to 5,000 miles. I didn’t mention this earlier, but the RPM limit on the Yamaha PW motor is 100 vs. 120 RPM on some of the newer motors or Bosch Performance Line. In practice, this means you will have to shift through gears more actively to achieve the full range of speed up to 20 mph. The display is impressive for being so basic, if you need the extra stats, that’s another area worth upgrading for. If you’re the kind of person who either doesn’t need to know those details, or you already have a cycling computer or app to track it, then the display functionally powers the system and you’ll likely love saving that money. Overall, I think that the Haibike HardNine 4.0 is a great bike for casual off-road, or even regular commuting. This review was performed by Mikey Geurts from Blue Monkey Bicycle in Utah in conjunction with Electric Bike Review and was paid for by EBR but was not sponsored or connected to Haibike in any way.


  • Available in four frame sizes, this electric bike offers higher performance and fit, I love how the top tube is angled down for lower stand over height (the battery slides out sideways to help achieve this wide
  • Excellent weight distribution with both the motor and battery mounted towards the center of the frame and kept low
  • The motor is powerful and responsive offering smooth starts and stops (measuring pedal cadence and torque to activate as well as rear wheel speed), you get up to 80 Nm of torque which makes it an excellent climber if you shift gears appropriately
  • Cost saving 100 mm travel spring style front suspension in tendem with 29er tires should scale moderate obstacles with ease but does weigh slightly more and isn’t as nimble
  • Beautiful paint and graphics… Haibike has long been an EBR favorite because of their unique styling and matching parts
  • The battery can be charged on or off the bike frame and is easy to remove (though it does not rattle or feel loose when mounted to the frame), it weighs about 6.5 lbs so taking it off could make mounting the bike to car racks safer and easier (more space in the triangle), both wheels feature quick release which is very handy for trailside fixes of flats
  • The Yamaha LED display system doesn’t clog the cockpit with screens, pads or mounts, just one simple display has the really critical readouts and is easy enough to reach while still holding the left grip (I love that it shows battery percentage and range estimate)
  • Large 180 mm Tektro Hydraulic disc brakes work well without braking the bank and you get adjustable-reach levers which are perfect for riders who opt for the smaller frame size and may have shorter fingers, or those who wear thicker gloves during the winter
  • Quick release axles front and rear for easy repairs and quick compact transportability, one big advantage of a mid-drive is that the drivetrain itself is more traditional and easy to work with for regular bike shops, you can swap out the front chainring for different sizes and possibly even go for a double chainring if you add a second derailleur
  • The Yamaha motor produces less noise than Bosch and Shimano E-6000 in my opinion, it’s a bit less noticeable (especially when riding on a dirt trail where the tires are already making noise just from rolling)
  • The cockpit is very open and clean compared to other eBikes with mounts, grip buttons, throttles, displays and dual shifters, the handlebar is extra long which also creates a sense of space
  • You can run 27.5 tires on this bike, maybe even with a wider tread if it can clear the rear triangle. Having the mid-drive motor really is a life-saver for folks using different wheel sets for different rides
  • The fork includes a compression adjust with lock-out which is especially nice for flat terrain where 29er efficiency is at its best, or if you want to use this to commute around town on paved streets


  • The display is more basic, smaller, and lacks some important features like odometer, trip distance, max speed etc., riding the bike regularly can either render that information less critical, as you may “mold” with the bike and understand it without prompting, or you may wish you had that information and remember every time you jump on the bike, the display is also non-removable and could take scratches and wear more readily
  • Aside from most of the other components on the bike, the plastic pedals are a bit more basic and could break under trail riding conditions, pedals are inexpensive however and you may want to go clipless at some point so this is a minor consideration
  • In our tests, the Yamaha system doesn’t get exceptional range from its system; 31.4 miles on full pedal assist on the road is perfectly fine, but it wasn’t close to the 48.5 miles we saw on the Bosch system under the same conditions
  • Unlike the Bosch drive systems, the Yamaha mid-drive doesn’t offer shift sensing which could lead to chain and sprocket mashing, learn to shift as the motor cuts out… when you stop pedaling momentarily and ease off
  • The battery charger seems unnecessarily large and bulky compared with some of the other options out there, I wish Yamaha would consider the magnetic EnergyBus port vs. their plug, which pushes in, and could get bent or knock the bike over if tripped on, the left crank arm passes it closely which makes it vulnerable… the charging unit itself is large and heavy and the cords don’t disconnect from the main unit
  • Haibikes tend to be more expensive and are frequently out of stock in popular sizes, I feel like they spread the line thin with so many options which can be disappointing if you visit a dealer and fall in love with a specific model or feature set
  • The drivetrain is alright, but not as durable, lightweight, or feature rich as the Deore XT with tension clutch for example, so you might get some chain bounce or drops easier
  • I like how smooth the motor winds down as you stop pedaling but it isn’t as instantaneous as some other systems, the traditional sized sprocket spins at the same cadence as pedaling so there’s less drag and noise when riding this electric mountain bike unpowered
  • Despite being a more athletic-oriented sporty electric bike, there are no bosses for adding a water bottle, you’ll probably need a hip pack or hydration backpack, there are a couple of threaded eyelets near the rear dropout which could possibly support a rack or fenders but no extra eyelets on the higher portion of the seat stays
  • I couldn’t figure out how to turn off backlighting on the display panel, I think it’s an always-on design which could be a little distracting at night if you prefer all-dark and stealth riding

comparing the hardnine 1.0 to this model, what are the main differences? does the hardnine 1.0 realy only have a max speed of 25 km/H when it has the same motor as the hardnine 4, and the exact same weight?

2 months ago

Hi Christopher, I think the speed limit for these products is based on geography where they are being sold. So, if you get a Haibike in the USA, it will offer ~32 km/hr top speeds (roughly 20 mph) but if you get it in parts of Europe, it will be limited to~25 km/hr (roughly 15 mph). Perhaps the Haibike HardNine 1.0 is only available in Europe? I found it on the Haibike website here and it appears to be a European model that complies with local legislation. I hope this helps to clarify, my guess is that the motor and battery hardware are the same, just the controller settings and firmware are slightly different to comply with the law.

If the input voltage for the yamaha battery chargers is 220v – 240v then do you need to increase the voltage from your household outlets which only give up to 120v both in the us and in canada? I ordered my bike from italy and it came with a european plug which is for the amount of voltage supplied in europe. If I only get an adapter without the voltage converter would that still be enough for the charger to work?

2 months ago

My guess is that a plug converter adapter should be all that you need. Maybe test it out? Perhaps it will charge slower… but I cannot say for sure. If you have issues, maybe you could order a separate charger from Haibike that is specific to your geography but will still work with the charger port design. You can also ask around in the Haibike Forums for advice because there may be users from all over the world with more experience than me with charging.

Zoli-So in your opinion, if you do not have the latest and greatest version of Bluetooth on your smartphone, you will not get the best performance from COBI?
My question: If you do not have a newer smartphone, can you just simply download the latest Bluetooth version on an older smartphone. (ie: I have a Motorola Moto E.) So in theory, this may very well explain why some owners of the Urban have connectivity issues and others do not??

Have a 2016 FullSeven Xduro RC and it came with Rock Shox 120mm travel Recon solo air forks. They were OK, but nothing like the Pikes on my Bulls. Also liked the slacker 66 degree head angle on the Bulls as apposed to the 69 degrees on the RC. I found a great deal on a new 160mm travel Lyrik but wondered if installing the longer travel forks on the 120mm travel frame would mess up the geometry. Turns out it totally improved the handling far more than even hoped! Don't notice the higher BB (maybe 20mm), but it gave me about 1 degree slacker head angle and just makes the bike so much better for the rocky terrain I ride. Before the upgrade I preferred my Brose powered Bulls, but now with the new fork and the e-Mtb mode software upgrade it's a total toss up!

I'm wondering if the geometry of this series of Haibike frames are pretty much the same. A buddy has the same year Sduro AMT with 150mm front and rear suspension and it has a 68 head angle which is the same as I now have.

Yup, I agree about the 750 WH battery. I’ve bought a second Yamaha battery so I can tour a bit more. The only issue with the second battery is that it’s not secured to the bike. I store it in a trunk bag. That means I can’t go shopping with it. I do everything with my bike as I live in a neighborhood which allows it. But I think that leaving an unlocked battery would be pushing it a bit.

I will probably keep the bike for a year or two more. It was a good deal and that’s not easy to find here. I really like the Stromer ST1x but it’s heavy and I have to carry the bike up a flight of stairs. The Haibike Trekking is very practical in that sense. I also like that it has quick release wheels. A flat is quickly fixed.

Lots of useful info.
I enjoy pedaling hard compared to spinning and I have always enjoyed Brose and Yamaha for that reason although I ride the Bosch trekking bike. Bosch Trekking S Rx has been great but I do wish it had more range. I wish this package had Supernova M99 lights and some higher volume tires.

This summer, I am switching to Big Ben tires and better fenders. Surprisingly, Magura brakes have been top notch on both Haibike and Stromer. Always reliable stopping power at my disposal and have been very happy with that.

If only there was a S-pedelec with 750Whr battery, <50lbs weight, Supernova M99 lights, Magura MT5 and 27.5" high volume tires.... Actually, I am thinking of getting the Trekking 9.0 Bosch bike and unlock it....

My error! My bad: Long ago I removed the stickers from my CCS front fork for a cleaner look.

I was presuming a model name by looking at the Suntour pages. Did not notice that the NCX-E is an air fork. Mine is definitely spring, with damping on the other side.

Thank you Nova Haibike and Thank you Chris Nolte for all the help and wisdom.

I now know to aim for an NCX-E when I replace the fork.

I'm a bike enthusiast and also a software developer so for me COBI's opensource API is a great test-ground for ideas. In deed I'm currently making a couple of customized 'Modules' for my rides via COBI API.

I think the issues that were experienced early 2016/17 was regarding Bluetooth connectivity dropouts. I have the a latest Android phone with Bluetooth version 4.2 and its is very fast without lagtime. So yes u will need latest iPhone or Android to be sure u don't experience lagtime etc.

As a footnote even without carrying your smartphone, your COBI.bike can still function as a front and rear light and you can still switch through the different modes of the AmbiSense Light System. Also, the electronic bell is still functioning. If you own an eBike you can choose the motor support levels using the thumb controller.
Looking at COBI development.docs the system is made to fall back to no GPS signals etc. So the bike should not come to a grinding halt if GPS etc. is not avail.

Why would Haibike risk destroying their reputation selling off a bunch of troublesome bikes to make a few bucks?! not...and the dealers hate low margin SALE bikes so they will always try to up-sell to their highest margin sales, just to keep in mind.

Just my 2cents..

I thought I would open this thread to go through all the flaws people see with the Trekking models. There are a lot of different variants, but a lot of these bikes share common parts. Just state your model and what you think Haibike (or its suppliers) could have done better. The idea isn’t to bash the bikes but to give a list of longterm ownership problems (and any workarounds), and maybe a couple of positives too.

I have the Trekking Sduro S 6.0 2017 which is the Yamaha 45km/h version available in the EU only. All in all it’s not a bad bike, but if Haibike had chosen slightly higher quality parts for certain key accessories, they could have built a better bike while maintaining roughly the same price. Yamaha and Magura should have paid a lot more attention to details.

Full specs are here:


A short list of issues:

[*]The bike comes with flimsy SKS chromoplastics fenders. The rear fender works as advertised, but the front one wobbles and makes an absolutely horrible noise.
[*]The Magura MT4 brakes progressively leak. A mechanic where I bought the bike said they’ve sold a lot of models with MT4 brakes and this is quite common. Each time you change the pads a little bit of liquid leaks out when you press apart the pistons. So you have to be ever so careful doing this.
[*]The Yamaha plastic remote is fixed onto the handlebars by two screws which bite into its casing. The remote constantly swivels out of place, which is very annoying. You cannot use WALK mode because of this. I've put a plastic band under the remote which only half solves the problem.
[*]The status button on the battery progressively regresses and becomes more and more difficult to use with time.
[*]The battery rattles, which can actually be eliminated by using a neoprene sleeve. For the summer you can use a cutout sleeve.
[*]The assist levels are not evenly spaced out on this bike. ECO+ gives a ridiculously low amount of assist, and then there’s normal ECO which is fine. But between ECO and Standard mode there is a huge gap. It’s really difficult to tour around in ECO mode on this bike because it takes a lot of strength. That impacts range a lot. I typically get 35-40 kilometers on a full charge (300 meter vertical delta, 95 kilo rider).
[*]The ride is bumpy. People have often placed the blame on the Suntour SR, which only has 63mm of travel. That’s true, but it’s only part of the problem. The narrow 700x38 tires are also part of the problem. And then there’s the frame. It’s so stiff that the rear bounces off each and every bump. The smaller the frame, the bumpier the ride… I have a 52 which is a size S. Guess that doesn’t help.

Some positives:

[*]The rack is often critiqued (Standwell Carrymore), but is actually one of the best parts of the bike according to me. It adapts to almost anything and is fairly sturdy.
[*]Brake lights are a nice addition. They're made by Busch & Müller (Toplight Line E Brake).
[*]Zero Cadence is really helpful in traffic.
[*]The bike climbs beautifully compared to some other 45km/h mid-drives. It’s not the fastest, but you can bet you’ll make it to the top of the hill each and every time. When things start to get tough, those 80Nm are there and you can feel them.
[*]Rims are top notch. These things stay true no matter what. (Rodi Black Rock Disc).
[*]Chain and drivetrain are built to last. Roughly 8000 kilometers and still good.
[*]Lights are always on, which annoyed me at first. But it’s a good safety feature.
[*]Mirror is tucked under the handlebars. Good job here too.
[*]The kickstand auto-retracts when sold, but if you remove a spring it behaves like a normal kickstand. Good job by the supplier on helping the user to get around the silly regulations here. It's a Pletscher Comp ARA.

The unscrutables:

[*]The Yamaha PW drive is amongst the things that are almost impossible to describe as good or bad. It’s just ‘different’. The drive likes torque input from the rider. That means not spinning too fast and putting a fair amount of pressure on the pedals. So you will often need to be in quite a high gear to get the best out of it. I would qualify the drive as being deceptively powerful. If you’re in those higher gears, and put in the effort, you can get a fair amount of power from this drive. If you want to go fast but don’t have strong knees and thighs, and want to spin instead of mash, this definitely isn’t the drive for you. People have said that the assist being limited to lower cadences (under 90-92) is a ‘bad thing’, but you quickly get accustomed to it.

Thank you, Chris. It is a spring shock, though, and has hydraulic damping. It is a good fork and I have adjusted the spring for excellent results.

I don't know diddly about these things and so I am thankful that you and Nova Haibike helped so fast!

OK, am understanding better. Two questions more, please, for Chris Nolte and Nova Haibike:

[*]why do street forks mostly have about 60mm travel and not double that amount?

EDIT: I looked up tapered steerer and learned why a straight headtube cannot be adapted to a tapered steerer:

I guess I will stick with what I have unless there is an air version available. As my present fork survived a car crashing into the bike, I want to replace it soon, anyway. It did take a hit; the fork is only scuffed up looking, but the headtube twisted the frame slightly. I will replace the entire bike eventually. For now, it is repaired and running and I wanted to learn if there are better suspension fork options. Perhaps not after all.

Thanks for any further thoughts.

Mi pedelec es Haibike trekking 5.0

3 months ago

Also trying to figure out Haibike models is tiring. Also I failed to get closer to the OTD prices some people claimed to get in these forums, heck I can't even get a discount on the advertised prices most of the time. Take these for instance:
https://electricbikereview.com/forum/threads/2017-commuter-ebike-izip-e3-dash-vs-haibike-trekking-4-0.15598/ ($3200 otd for Xduro Trekking S, $2200 OTD for Sduro Trekking 4.0 ? ) or this one 2017 AM7 for $3800 OTD https://electricbikereview.com/forum/threads/considering-the-2017-all-mountain-7-and-possibly-the-2017-full-7.14943/? No one came remotely close to that price. I will really appreciate if somebody points me to the dealer who can somewhat come close to these prices.

The problem with the official discounted prices of Haibikes is that the new models are named differently so you can not easily compare them to the 2018 counterparts to see if it is a good deal. After going through the specs thoroughly(and spending a lot of time) I actually saw that some of them are more expensive than the similar 2018 models. For example take

2018 Sduro HardNine 4.0 (this one comes with Bosch CX system) $2600

2017 Xduro Cross 3.0 (comes with Bosch but with 400Wh battery) $2800

Can somebody tell me what I am missing because when I look at the components I feel like the $200 cheaper 2018 model is actually somewhat better than the discounted Xduro model?

Sorry about the tone of the post, it became quite tiring trying going through specs.

@8:09 That is disappointing - how can Haibike have such a detailed display but no ODOmeter?? Aside, from speed and battery life, how far you've gone is the key info I'd want.
(Also, Haibike desrves a serious critical dopeslap for making their needlessly confusing nomenclature even worse with Xduro/Sduro Bosch/Yamaha switcheroo .)

Yeah, I completely agree with the name change update thing... and will ask them about it at Interbike and express your frustration :)

Dude.... the switcharoo is killing me. Between 2016 and 2017 they improved their model naming from letter code to scaling number code, but now with the XDuro and SDuro cross over, I feel like the brochure is a textbook.

An obvious comparison would be to the Voltbike Enduro. The MD on the Volt is the Bafang Max, frame integrated and torque sensor based. That's a pretty sophisticated motor. It just seems like if Bafang can create good torque sensor systems that low level manufacturers can integrate into frames and sell for considerable $$$ below Bosch/etc, they have a winner. The Max Ultra at around the legal limit for power seems to be available with both torque sensing and a throttle. There's a lot of stuff out there. Around $2k would be a better price, especially for people with no dealer support anyway. Monkey is a day's drive. Lectric may sell these out of Vegas.

Good thoughts George, I really like the new Bafang Max drive... it's powerful, quiet, and just a bit cheaper WITH throttle option

Jesus christ this bike for 2.5k, I understand the frame is pretty good but this is not what people is looking for in an electric bike. I don't really understand the sole purpose of this bike. In my opinion I recommend E-bikes to have long range and I know that is where the cost is, but it will be more convenient and reliable.

Hi Carvell, I will keep an eye out for the other Vado models but only had access to the 6.0 during a press event earlier this year. I thought they woudl have others and staged some reviews for the 3.0 and 5.0 but that never happened and no shops around me have had them. In any case, the 6.0 has a lot of good info if you haven't seen it yet: https://electricbikereview.com/brand/specialized/
