  • One of the most popular bikes in the Kalkhoff line, it comes in four frame sizes, three frame types (including wave step-thru) and two colors, impressive two-year complete warranty
  • Excellent hardware including Shimano hydraulic brakes, and internally geared 8 speed hub (that can be shifted at standstill), a Gates Carbon belt drive and reflective puncture-resistant tires
  • Wonderful menu system with adjustable power delivery, responsiveness and readouts, I love the range estimator and precise battery indicator, you get a Micro USB charging port on the display and an optional Bluetooth app for turn-by-turn GPS navigation from your phone
  • Not my favorite pedals, the bike weighs quite a bit (due in part to basic suspension fork and larger battery capacity), thicker display isn't removable, costs more

Written Review

I was told that the Include 8 is one of Kalkhoff’s most popular pedelec models, at least outside of the US. It’s an electric bike that packs in so many features you could literally replace your car for short trips… It’s a complete package, a bike that doesn’t require extra thinking around safety, utility or style because the accessories are already there and they meld seamlessly with the purpose-built frame design. There are three frame types and two colors to choose from so you can personalize a bit. I’m a fan of step-thru frames for mounting convenience but prefer the stiffness of high steps and with the Kalkhoff Include 8 Premium there’s an option that blends the two called Trapez (sort of a mid-step) and it even squeezes in a bottle cage mounting point! Whether you’re tall, short or planning to share the bike it should be comfortable because you can make adjustments to the seat height and handlebar angle. It’s a bike with efficient reflective tires that also has a suspension fork, seat post shock, comfort saddle, ergonomic grips (name brand from Ergon) and a more relaxed swept-back bar. To me, it’s a great compromise of utility and comfort but you do pay more and the bike isn’t light. At nearly 60 lbs, this is not the electric bike you want to lift up stairs or onto bus racks. Yes, the battery is removable (along with the front wheel) but given the long-range battery capacity, perhaps you can skip the bus ride alltogether? In short, this is a winning commuter e-bike and one that comes standard with a two year warranty.

Driving the Include 8 is an efficient but powerful mid-drive motor. It’s compact, well integrated into the frame design and it’s smart too! The motor listens for wheel movement, pedal cadence and pedal torque so it starts and stops quickly as you interact with your legs. You shouldn’t experience any unwanted starts in cases where the bike is stopped but you’re pressing on the pedal for balance. And conversely, you shouldn’t have to push for long when starting off in order for the motor to jump in and help. One thing I really like about the Include 8 Premium is its internally geared eight speed hub that can be shifted at standstill. Say you pedal up a hill but have to stop part way… this 60 lb bike is not going to be as easy to start again right? This is exactly when you’d want to shift down into an easier gear and start from there. In practice, it doesn’t work perfectly (I had to pedal a stroke for the gear change to happen during my ride test) but it’s much easier than with a traditional derailleur, chain and sprockets mashing. The drivetrain is clean and quiet because it uses a belt system instead of a chain. Unfortunately, the Impulse 3.0 motor system is not so quiet. You get a whopping 100 Newton meters of torque but there’s more electronic whirring compared with older 2.0 models. So coming back to how responsive the motor is, you also get shift sensing that relies on physical signals to cut power and reduce strain on the drivetrain. Perhaps the best part of these features is that you are put in control of them. There’s a climb-assist feature that lets the motor push longer, a shift sensing delay and and other power settings to maximize efficiency or torque and it’s all available through the standard display.

The display itself is large, backlit and well laid out. I like that the battery info-graphic shows precise levels vs. five or six big chunks and there’s even a range estimation so you can plan trips according to capacity and assistance dynamically, in real time! Interacting with the menus, switching through ride stats or holding the set button to dig into settings, is very comfortable thanks to a rubberized button ring near the left grip. It’s backlit (but not too bright) and less of a stretch than with a lot of other systems. Once the battery is charged, mounted to the bike and you press the power button on this ring the display comes on and you’re really all set to ride, pressing plus or minus for more or less assist. The trade-offs are in how large the display itself is and the fact that it’s not removable. For how polished the frame, fenders, lights and other accessories are on this electric bike I was put off by the thick plastic display. The wires extruding from the back seem to bend a bit when I forced the display all the way forward (simulating a taller rider or a glare-reduction situation). I love that it angles and really appreciate the Micro USB port on the back but feel that, given how nicely this ebike would work for commuting, a removable version would be ideal.

The battery design and capacity are stand-out features on the Kalkhoff commuter line… not just the Include 8. The pack is so custom, it fits perfectly behind the seat tube and even curves to match the outer profile of the rear wheel, acting like a fender extension. The battery uses long lasting light weight Lithium-ion cells offering 36 volts of power and nearly 17 amp hours of capacity. The charging port is magnetic so your cable wont tip the bike over as easily if it gets tripped over and the chargere itself, while large, is relatively light for easy inclusion on rides. If you added a trunk bag on the rear rack, you’d have plenty of room for the charger even if the saddle was lowered all the way because the rack is positioned further back due to the battery position. This is not just some converted frame, everything is custom and the wires are all internally routed, even for the lights! Both lights run off the battery as well and there’s a setting in the menu that allows for a delay in switching off so you’ll be more visible when parking and locking.

There’s so much to say about this bike and I feel that the video review above does a good job along with all of the pro’s and con’s listed below. As someone with back and neck sensitivity, I love that they included several features emphasizing comfort. As someone who cares about reliability, the puncture resistant tires, sealed mid-drive motor and premium belt system (with a center-tracking system to keep it aligned) are awesome. The suspension fork could be better (it does have lockout but weighs a bit more than a nice air fork) but when you really start to look at the price of $4,400 it makes sense that they had to compromise on some components. Many of the high-end electric mountain bikes I test are in the $5k+ range and they do weigh less but lack all of the utility features found here. I love the reflective tires, bright white frame color option and integrated lights. Depending on your needs for durability and range, I feel confident that this product would be a leader. It comes from a larger company with a longstanding reputation and is sold exclusively through dealers so that’s the final question. Do you live near a dealer where you could take a demo bike out for a ride and then order the perfect size and type for your lifestyle? If so, definitely give it a look and sound off with your experience here.


  • The belt drive system is clean, quiet and durable compared to a traditional chain, because this ebike uses an internally geared hub you don’t have a derailleur sticking out which could get bumped at bike racks etc.
  • 8 speed Shimano Nexus allows you to shift at stops, this is very convenient if you are climbing and forget to shift down at a light or stop sign
  • Sturdy rear rack is positioned well behind the saddle allowing for larger trunk bags (and it works well for short riders who have to lower the seat all the way), I like the pannier clip hole at th ebottom as well
  • Quick release front wheel and removable battery pack bring the weight down when transporting this bike… because it’s a bit heavier than most at nearly 60 lbs
  • Premium lights keep you seen and illuminate the path, the headlight offers a solid 100 lux and they feature an adjustable parking delay so you’ll be visible for a bit even when the bike is shut down (perhaps when you’re locking the bike near a busy street), I also love that they upgraded the tires to have reflective sidewall stripes
  • Available in three frame sizes including an ultra low wave design, this frame type is the most accessible when carrying gear on the rack and for those with limited strength and flexibility
  • In addition to multiple frame styles, you also get four sizes and two colors to choose from which could keep the bike unique if you’re buying multiple or a his/her setup
  • Full-length plastic fenders and chain cover keep you clean and dry, they stayed relatively quiet during my ride tests and felt sturdy
  • The adjustable length kickstand is positioned well towards the back of the bike, it won’t collide with your crank arm but is angled forward to still support the battery weight at the middle of the frame
  • Built-on cafe lock might come in handy for quick errands, the battery locks to the frame securely but doesn’t require that the key be left in while riding
  • As someone who commutes by bike to work, I appreciate relaxed seating position with included seat post suspension and suspension fork up front, the bars were swept back and the adjustable angle stem let me raise them even more, I also liked the ergonomic locking grips from Ergon
  • Internally routed cables (electronic, shifting and brake lines) keep the frame looking clean (especially the white frame) and are less likely to get snagged
  • I love the way the motor and battery are built into the frame, they keep weight low and centered but allow for bottle cage bosses which come in very handy
  • Excellent two-year warranty, Kalkhoff has a great reputation worldwide and their products are only sold through dealers which usually means better builds and support
  • Hydraulic disc brakes are easier to use, requiring less hand strength than mechanical, and have adjustable length levers so people with smaller hands or those wearing gloves can have an easier time
  • The Impulse motor system is compact, it offers impressive power and functions with shift sensing in order to reduce chain and sprocket wear (even less of an issue with the belt drive and internally geared hub on the Include 8
  • You can actually adjust how sensitive shift sensing is on this bike along with several other drive characteristics like climb assist
  • I really love the button pad used to change assist levels on the Impulse ebikes because it is backlit (but not super bright), and mounted close to the left grip for easy access and use while riding and steering
  • The battery can be charged on or off the bike and uses the EnergyBus Rosenberger standard (which is magnetic), if you trip over the wire or move the crank arms while plugged in the bike is less likely to tip and the pins probably won’t get bent and broken, this port type can also send data for firmware updates etc. not just for charging
  • I love that the display panel has a Micro USB charging port built into the back (so you could keep your phone, music player or other portable electronic device full) but wish the display was thinner and removable, it does allow you to adjust the angle for reduced glare thankfully
  • The display readouts are pretty nice and include a more precise battery info-graphic and range estimator, many other electric bike screens just show five dots to indicate charge level
  • Rather than requiring users to download a smart app or go to your dealer for help, the Impulse system lets you explore and adjust LOTS of settings directly from the bike and I like that, the menus are pretty well organized and I miss these options when testing other bikes… Kalkhoff does have an optional GPS app you can download and link with Bluetooth to get turn by turn directions using the bike display


  • At nearly 60 lbs, this is one of the heavier city style ebikes I’ve tested and reviewed but you do get a more complete package (fenders, rack, lights, lock) and the battery capacity is way above average… there is also a walk mode you can activate by holdig the plus button for a few seconds and this runs the motor at a low speed so you don’t have to push the bike
  • You do pay a little more for this bike than seemingly comparable models… but you definitely get a quality product, especially when frame type and sizing are factored in (they add cost to production)
  • Some adjustable angle stems can loosen over time, especially if you’re riding on bumpy terrain, keep an eye on this one and consider carring an appropriately sized allen key along just in case
  • The tires on this electric bike are not super fat but rather efficient which improves coasting range but makes them less comfortable (due to higher PSI requirements) and more prone to pinch flats, check their pressure often because the added weight of the ebike systems contribute furthr to the possibility of punctured inner tubes… I love that at least the tires have a puncture-protective lining which will fend off some flats
  • The display panel is not removable so if you’re using the bike as a commuting platform, it might be exposed to scratching, rain and sun damage over time… I usually park away from the crowded racks and sometimes drape a little cover over displays so they aren’t noticed as much
  • I didn’t get to see the stock pedals for this bike but was told they are plastic platform with rubber tread, I usually prefer metal like Magnesium which is light and durable with great traction (considering the higher price that would be a nice thing to get)
  • The fork used on the bike is an oil spring shock vs. an air spring which would have been lighter, it offers lockout which is nice but otherwise feels like a more entry-level part (I do like that it’s color matched)
  • I’m used to the Impulse motor system operating more quietly, the ride test surprised me becasue it sounded a bit louder this time

It's a swift paced overview of new ebikes that haven't made it to the U.S. yet and others that we're already familiar with along with a flash of some nifty accessories. Liked the trippy music overlay and Court lists all of the items he zoomed in on in a list below the video. Don't know how the London Bike Show compares in size to our Interbike; however, it looks like a huge show!

Hi guys, I was visiting London to film some reviews with a shop called Fully Charged and happened to wind up at the London Bike Show. This video is a quick overview of interesting products I saw. Each shot takes a moment to highlight the electric bike or accessory and then show the name of the company who produced it. One of the highlights for me was the new Electric Brompton. I have not gotten a chance to ride it yet. The music used in this review is from Be Svendsen, used with permission.

This fellow should be pretty reasonable. https://www.hicbattery.com/Battery-Rebuild-Services_ep_41.html
You may be able to find a pack to fit but I'm afraid there might be some pitfalls and problems that would arise. You could use a soft pack battery in a nylon case in place, but I'd consider going the rebuild route. It's really not a very big pack maybe 7S/3-4P 21-28 cells. And with newer 3000-3500maH cells you'd gain aH and range. Careful if you decide to buy a soft pack and adapt. Make sure the reseller has been checked out. I can reference one to be trusted, but again, Call Hi C first!

Thanks very much. I'd like to try an alternative battery given the age of the bike. Within a couple of years I'm likely to get a new bike but the available options seem to keep on getting better and other than the battery issue my Kalkhoff serves my needs.

Amazon lists a number of relatively cheap 24v ebike batteries and I see that the second pedelecs entry that you copied gives the necessary information on electrical connections. I am pretty sure that I can figure out a way to mount the battery on the bike but I am concerned about waterproofing and making connections that won't shake loose. Is there any way that a pre-made battery back (one that doesn't require that I do spot welding between cells) might fit inside the case for the current battery? For example, this web site lists what they call "naked" battery backs like this one here (https://ebikemarketplace.com/collections/lithium-batteries).

In terms of having the current pack re-celled, the forum entries on this site made the process seem time consuming, a bit uncertain and likely close to as expensive as a new battery pack if I could find one. I'm not sure if that is an accurate evaluation on my part.

Thanks again.

EDIT after being frustrated at the lack of information I gave it one more try. There are alternatives. AND you could save a lot of $$ by using an alternative battery. BUT it CAN be re-celled. You may have to subscribe.

Read to post #16 in this thread. A 24V battery and some simple soldering or wire crimping will work!

There's a shop in Las Vegas, and a fellow on Facebook in the endless sphere group that does repairs. I spent a few minutes trying to find information on their batteries, but there's not a lot out there. My biggest worry would be having a proprietary communication system that needs to be in place to "talk" to the controller. I can't find that answer either. Spend sometime researching and reading forums to gather as much info as you can and I'll happily help you find a solution, or repair person.

From the comments section in that article;

I build and service all makes of ebikes.
Simply put, you are wrong.

Hub motors are far more reliable, less complex, and can put far more power to the ground than any mid drive. The mid drive total power is limited by the chain and freewheel. These are drive train parts which were never designed to handle the torque of any motor, they were designed for human power (which is about 250 watts if you want to translate that to electric force). You are stressing these components far beyond their design parameters with a mid drive.

There is more room for a larger and more powerful motor within the wheel than there is between the cranks. I don’t know where you are getting your information about lack of power from hub motors, but I can easily build a 60+ MPH bike if anybody is foolhardy enough to ride one. Climbing hills is not a problem. You speak of uneven weight distribution. Most of my customers prefer a very erect riding position to the more aggressive racing or mountain bike stance. When sitting erect the balance is pretty uneven (biased to the rear) on most any frame I know of. If the rider is very concerned with weight distribution there are very reliable, quite powerful geared hub motors available.

On average they weigh about 6 Lbs. the standard bike hub (about 1 Lb.) is replaced by these, so effectively about 5Lbs is added to the front or rear wheel. If you carry your lunch in a front or rear basket you are already altering the weight bias by the same amount.
Hub motors have far fewer moving parts, if fact a direct drive hub motor only has the stator rotating within it, and no other gears, clutches, freewheels, Etc. These motors will go thousands upon thousands of miles trouble free.

Electric motors have full torque at zero rpm, so I don’t understand your claim of more power obtained by a gear reduction. If the motor is of appropriate size, there is no hill or terrain which will challenge the motor.

Another thing to note is that the Bosch mid drive is not serviceable in the USA. All units are required to be returned to the factory in Germany for service. That should run up a pretty hefty shipping bill (more than the cost of a hub motor) and require a pretty fair amount of time when the unit needs to be repaired. I’m not aware of other manufacturers repair or parts policies.
I believe it’s a no brainer, the hub motor makes far more sense.
You write this article as an expert, but clearly you do not have the experience and information to write an in depth article about this subject.



Heya Shepherd,
Welcome to the site and thanks for your input. It’s great to see that I’ve created a discussion which allows us to clear things up with experiences that different people have had.
Firstly, with your point that hub drives are more reliable and less complex, I completely agree. I did state that in the article, not sure if I was clear on that or not (my apologies).
I can see where you’re coming from with the rest of your points such more power to get up a hill and the added drivetrain stress. This article was written as a general comparison between the two types of motors, towards the more general consumers interested in eBikes, and whom would most likely want something not so ludicrous.
So when comparing a general hub motor and a general mid drive motor, a mid drive motor would outperform a hub drive on hill climbs without a doubt. Do you agree with me there?
I won’t deny the fact you can get a hub drive motor that can get you up a hill, but to match the hill climbing performance of a mid drive, you’d need a higher output motor yes? It makes sense, otherwise high end electric bike companies (no matter if it’s commuter or eMTB) wouldn’t use a mid drive system. If you look at Haibike, Kalkhoff, Riese and Muller etc., they all use mid drive motors.
Like you said, there is added stresses to the drivetrain which I also mentioned in the article. However typically speaking when a cassette, crankset etc., are designed, they are designed with engineering safety factors such that they can withstand forces greater than typical usage. But even with that, I agree there still is a lot of stress on the gears and I have seen quicker damage to it. To combat this, bike manufacturers and riders could use the SRAM EX1 drivetrain. These are designed for eBikes and are more robust.
Your point on the weight distribution is fair for rear hub drives that are compact. Anything large or if equipped on the front hub, the balance of the bike would change significantly.
Yes electric motors exhibit maximum torque at stall RPM like I mentioned in the article, however I wasn’t clear with the power statement. With mid drives, you can actually change your torque value. With hub drives the maximum torque you’re receiving and going to output to the ground is fixed to whatever the motor is capable of. Since a mid drive uses the gears on the cassette, a change in the ratio of the cassette or chainring can increase torque and power. Using a 11-42t cassette will obviously output more torque to the ground than a 11-36t cassette. Same deal with the chainrings. As for power to the ground, if you get a 250W hub motor and a 250W mid drive motor on the exact same bike and ran a dyno test, the 250W mid drive motor will have a greater power band.
As for servicing Bosch motors in Australia (we’re Australian based), I think we have a service centre locally. Regardless there is still shipping and more costs, which I also did mention in the article.
Simply put, the mid motors are generally a better performer, whereas hub drives are more reliable and cheaper. It depends on what the rider is looking for, and I was going to answer this article with that answer, but like I said it was a little too cliché.
I never mentioned I was an expert, however with an engineering background, it does help me understand the mechanics better which I attempt to explain to the general audience.

I have a 2010 Kalkhoff pro connect sport, which I have used a great deal. The battery has lasted a lot longer than I had expected but is now starting to fail. The bike has a 250w Panasonic center drive motor that runs at ~26 volts. Replacement batteries used to be readily available but I am not having much luck finding one quickly. Also, I know that the batteries were upgraded in terms of capacity but I don't really need that capacity for my daily commute. Given the age of the bike I am a reluctant to spend the roughly $800 that the high-capacity batteries were selling for in the past. I'd appreciate suggestions about where I could get a suitable battery or whether the current battery could be re-celled.

The combination of super-moto tires, mid-drive motor, belt drive, and Alfine 8 IGH, on the Pedego Conveyor means for comparison sake the same tires and belt drive are on the Riese and Müller Charger which with the Nuvinci IGH is the same $5k price and $300 more for the Charger with a Rohloff IGH. If you wanted the tires but could live without the belt drive and IGH you might look at the Moustache Friday. Other belt driven mid-drive ebikes include the Scott Silence, Bulls Lacuba, Evelo Galaxy, Piaggio Wi-bike, and Kalkhoff Integrale. All of these would be a nice commuter ebike.

Enjoyed Mike's erudite post last month on this topic. I have a Kalkhoff Include 8 Premium (with which I have been v pleased), and thought it was a Hub, but I guess it is actually a Mid-drive--is that right?

2 years ago

The S11 comes in four frame sizes, so size should not be an issue, even with 28" wheels. My wife clearly wanted smaller wheels and step through frame....and loves her Sahel....she is 5'5" and could never ride my large frame S11.

As far as an integrated battery goes...well Kalkhoff only offers them with the diamond (high crossbar) frame.

The Kalkhoff Include 8 Premium is a sweet bike that has: belt drive, internal gears, step thru frame, shock absorbing seat post, 26 inch wheels and mid drive (less powerful with pedal assist up to 20 mph). By the way...the battery comes with a dock, making it very convenient to recharge.

You really haven't mentioned how much power you want. The Kalkhoffs are very smooth with "under the radar power". The Stomers have a ton of power and you feel it. Of course you could buy the new Stromer ST2s....spendy...but state of the art.

Good luck Noreen....choosing the right bike can be complicated, but the process of searching can be fun.

I bought a Kalkhoff e bike and loved it. Sadly 9 months ago I needed a replacement part but Kalkhoff has not been able to supply it. This means I have an expensive pile of scrap iron in the shed. This is a disgrace and people need to be wary of buying a Kalkhoff or if they do check the availability of the wearable items. I have had to buy a new bike, needless to say it is not a Kalkhoff.

I live in the South of France and have just purchased my first electric bike a Kalkhoff Include evo i8 step through. I bought it from the UK because it was cheaper than buying in France and they are transporting it free. People say why such an expensive bike? Well I can afford the best so why not. People never look at a Ferrari or Porsche and say why such an expensive car. I'm a fit 75 but I don't want to dress in ridiculous lycra and wear funny shoes nor do I want to sit on a razor blade plus I don't like hills. So electric is the way to go.

A Timing belt would be under a different type of load. I'm thinking about mountain biking, but then think again that bike is not a mountain bike. The amount of torture I do to a chain on a mountain bike is way worse than some engine would do.

Hi Robert, my experience with belt drives is limited but thinking to my car which has a timing belt (that has to be very precise or it could mess up the engine) I believe they can be made to not stretch. The one on this bike is a carbon belt from Gates which is top of the line :)

Hi Court! Great video - love your work! You've reviewed a few bikes with the Impulse drive, and you usually mention that there is a delay in the motor cutting out when you stop pedalling - the chain keeps going for a revolution or two.

This is intentional, it's the Climb Assist feature. You can turn it off in the settings, and the motor will stop as soon as you stop pedalling. You know that the motor can immediately stop, because it does exactly this when the gear change sensor is engaged.

I find the Climb Assist feature useful when starting out, or crossing a road at a pedestrian crossing. Just give a pedal a shove and off it goes by itself for a few metres. It takes a bit of getting used to - and must feel strange when you are always testing different bikes. But it's not a negative, I find it to be quite a positive. And it can be turned off if you would prefer.

Thanks mate!

1 year ago

In the writeup I called out climb assist and was wondering if that's why it wasn't stopping so fast. This ebike was reviewed at the Kalkhoff main offices in Southern California and I was walked through some of the settings but maybe didn't reset everythign? I try to be thorough but must have missed turning this off and testing it. Thanks Rob!

I've been watching these reviews for nearly half a year now. I find them very interesting and informative. Would I like one, sure. Would I buy one, No. Yes they are insanely expensive, and most high end bikes are. If people are willing to pay this much for a bike then the manufacture will charge the consumer accordingly. As it stands I'd never buy one, as you could buy a high quality motorcycle for a similar price point as the majority of these bikes, but still cool nonetheless.

Cool, glad you're enjoying the videos Benjamin. At some point I think prices will spread out more and drop. There are already a few affordable ones (which to me is ~$1,500 or less) and I list them here: https://electricbikereview.com/category/affordable/

Very well thought out and sophisticated bike. I would love to see you visit Denmark or the Netherlands for a review of the bike culture there. My 2 yr old grandson is riding a balance bike in Denmark. All the kids start out on them...no training wheels there! Here in St Louis ebikes are nonexistent. The focus is on sport rather than transportation. My all time favorite is still the Juiced Riders cargo bike although they don't seem to be moving many of them. Practical Cycle in Sacramento has their last two on sale and I wish I was there to buy one! Keep up the good work.

Ha, riding up and down where I live means a lot of riding up and up and god the slope is just getting worse just end already, damnit.... Unless you've got a shower wherever you're going (not really happening), not practical for getting around, just for recreation. I can see the practicality of an e-bike, although, yeah, the prices are a bit brutal.

Regarding max speed, it's low - because else it'd have to be registered as a moped. So the motor cuts out as you get to the top speed. The motors are 250W on paper, it's the maximum continous manufacturer rating - they output a lot more peak power, but by law it has to cut out as you go faster.

Hey, I love your videos. I have a small suggestion: when you are going over the specs of the bike, state the Wh (Watt hours) instead of just the voltage and amp hours. Whs are becoming the standard metric that people use when discussing batteries and it gives a much clearer idea of the capacity.
