  • A premium speed pedelec designed for hassle free, reliable and quiet commuting with a two year warranty, available in four frame sizes for improved fit, adjustable stem
  • The Gates carbon belt drive is near-silent and stays centered with CDX tracking technology, an 11 speed internally geared hub requires less maintenance and is less vulnerable than a derailleur if the bike tips
  • You get a sleek rear rack, integrated lights and fenders, a battery that can be charged on or off the frame and one of the deepest interfaces I've seen with lots of adjustability
  • The battery rotates in vs. clicking straight down and can get a little tight at times, the display is rather large and isn't removable, the bike costs a lot

Written Review

The Kalkhoff Integrale S11 is a speed pedelec (capable of 28 mph top speeds, assisted) with an internally geared 11 speed hub. It runs a clean, quiet belt drive instead of a chain and comes outfitted with a sleek rear rack, plastic fenders and a bottle cage mounting point so it’s ready for commuting or a bit of touring. I was impressed with the name brand extras… locking ergonomic grips from Ergon, hydraulic disc brakes from Magura, integrated LED lights from B&M and a light weight air suspension fork from RST. You do pay for these upgrades however and at $5,699 this is not a cheap electric bike.

The first thing I noticed about the Integrale S11 was how nice the frame, fork and battery looked together. Everything is color matched here and the integrated design nearly hides the fact that it’s an ebike. Kalkhoff is using the Impulse 3.0 drive system for this model and the custom battery was designed to rotate in from the side instead of clicking down. This reduces the vertical clearance required to seat and unseat it which makes bumping the pack on the top tube and seat tube less likely. Getting it on and off required a bit of experimentation for me (I approached the bike without any kind of introduction from the team). First you unlock it then pull at the top of the pack from the left side of the frame and it will start tipping out. After doing it once, the process got a lot easier and you can see it in action in the video review above. The one thing I noticed however was that there’s a bit of play even when the pack is securely locked in. I didn’t notice it rattling a lot during my rides but there was a gap along the bottom and perhaps some foam pads or bumpers would help with future designs?

The battery charges using an EnergyBus port that’s magnetic, it can be charged on or off the bike and weighs about seven pounds so removing it will bring the bike down to ~48 lbs total making it easier to lift onto car racks or carry up stairs. The front wheel is removable using quick release but the rear is bolted in, perhaps since it uses an internally geared hub without a chain tensioner. Thankfully, the upgraded Schwalbe tires have a puncture resistant layer. I mentioned lights earlier but the tires also have reflective sidewall stripes keeping you visible from the side. Considering the bike only comes in this dark gray/black color scheme, I’m glad they added those for safety. You can get this bike in four different sizes for optimal fit and it felt stiff and responsive to me during the tests, even at high speed! Instead of using a standard 11 mm skewer up front, Kalkhoff upgraded the axle to 15 mm like you’d find on some mountain bikes. This improves strength and makes the wheel easier to get on when you’re lining up the disc brake rotor in my experience. This, combined with the tapered head tube and diamond frame make the bike feel solid.

While the battery configuration is more range oriented than power, I found the bike to be quite capable when accelerating and climbing… It offers 36 volts and 16.75 amp hours. The motor is rated at 350 watts nominal, but offers a massive 100 Nm of torque! That’s more than almost any other mainstream mid-drive I’ve tested. In practice, it feels similar but that may be due to my lighter weight of ~135 lbs. I had a great time climbing and speeding along on the flats. I had no problem hitting ~28 mph in the ultra setting and noticed the responsiveness of the assist sensors which measure rear wheel speed, pedal speed and pedal torque. Along with that power, you also get sensitivity because this is one of the few e-bikes out there with physical shift sensing. It’s designed to ease off a bit when shifting gears so you don’t end up straining the belt or mechanical shifting mechanisms.

So many of the drive settings can be adjusted with the Impulse 3.0 system, it’s truly versatile and delightful to explore. Whether you want the lights to stay on for a few minutes after you’ve stopped ridding (for safety) or you want to dial up the shift sensing… you can link the display to your mobile phone for GPS enabled turn by turn directions, you can dial in how quickly the motor responds to your pedal input and you can adjust the maximum speed. Note that riding over 20 mph significantly increases air resistance and drag which will cut into your range. If you enjoy the speed and don’t have as far to go, enjoy the zippy Class 3 performance but otherwise, consider dialing it down for maximum range. While I wasn’t super impressed with the large plastic non-removable display panel, I did like the options it presented and that fact that you didn’t need to download an app to access all of them. I love that it had a Micro USB port built into the back for charging your devices on the go and at least it can be angled to reduce glare. All things considered, this is a fantastic bike that’s ready to dominate urban landscapes. It looks great, handles well and comes with an impressive two year comprehensive warranty. Kalkhoff is a leader in the European market where they thoroughly test their frames and final builds. I could see the quality and felt more comfortable at high speed than with some other competing bikes. Big thanks to Kalkhoff for partnering with me for this review.


  • As far as speed pedelecs go, ebikes that can top 20 mph, this one is super streamlined and quiet thanks to its internally geared 11 speed hub and carbon belt drive
  • The belt drive is from Gates, a trusted leader in the space, uses carbon strands for strength and has an alignment strip down the middle so it won’t slip
  • The internally geared Nexus hub isn’t as vulnerable if the bike tips and shouldn’t require as many tuneups as a more traditional derailleur… it can also be shifted at standstill
  • Sleek rack design capable of supporting ~15 kg (~33 lbs), it isn’t as wide or bulky as some other racks I’ve seen but also can’t carry as large a load
  • I love that the bike has integrated lights, they run off the main battery pack for convenience, you don’t have to take them off each time you stop and the rear light is integrated with the rack so it won’t get blocked as easily a seat post lights (jackets can sometimes hang down over that style)
  • 2″ wide Schwalbe Big Ben tires improve comfort, have a puncture protection lining, reflective sidewalls for safety but still roll efficiently thanks to an urban tread, I like that the fenders are wide enough to completely cover them and how good the fenders look
  • High quality physical shift sensing protects the gears when pedaling hard and shifting simultaneously, it’s one of the best designs around
  • Lots of system adjustability here including how quickly the bike responds and how long it continues after you ease off on pedal torque (that’s their climb-assist feature), how much battery is reserved to power the lights if you’re getting low, you can even connect with your phone with Bluetooth for turn by turn GPS feedback or tune down the top speed from 28 mph to 20 mph or lower if you want to optimize range or just improve your own feeling of comfort and safety
  • Quick release on the front wheel for easy maintenance (I would say it helps with transport but the fender is still there and could be vulnerable without the wheel), I like that the axle is upgraded to 15 mm for strength given the higher top speeds here
  • Very sturdy adjustable angle stem to help dial in your body position, ergonomic grips and a suspension fork… consider a 31.6 mm seatpost suspension for even more comfort
  • Excellent weight distribution, the motor and battery are centered and low, in my opinion the weight of the bike is actually fairly low at ~56 lbs given all of the accessories and suspension as well as the large battery… I think the fact that it uses an air fork helps
  • Available in four frame sizes for improved fit, this is important considering that the frame only comes in a high-step design, I love that the managed to squeeze in bottle cage bosses on the seat tube! Consider adding a side entry cage or sturdy folding lock here
  • You can adjust how long the lights stay lit after you park (for safety as you lock the bike) and the rear light activates more brightly when you squeeze the brake levers
  • Solid two year comprehensive warranty, Kalkhoff is part of the Pon Group which also owns Gazelle and Focus, they are a leader in Europe
  • The charger uses the EnergyBus Rosenberger interface standard that sends data and electricity for easier diagnostics at the shop and a safer plug (it’s magnetic and just unclips if you trip over it vs. bending pins and knocking the bike over), it charges at 3 Amps vs. just 2 Amps for most e-bikes I test
  • I love that they included a Micro USB charging port on the back of the display panel! This lets you charge mobile devices like phones or music players and it’s mostly out of the way so you won’t snag your feet or arms while riding the bike
  • The button pad that you use to interact with the display panel on this bike is excellent, it doesn’t take up too much space on the bar, is backlit for easy use in low light conditions and seems very durable – well sealed against water
  • This bike offers excellent torque power with up to 100 Nm output, it should climb easily if you’re in the higher levels of assist and shift gears appropriately
  • This is a completely custom, purpose built electric bike with internally routed cables, matching paint across the frame, battery pack and fork and it just looks great


  • The display is kind of big, clunky and ugly in my opinion… you can’t take it off and the plugs at the back can get squished if you angle it far forward
  • The “rotate in” battery pack is unique and allows the top tube to be lower but can be a little tricky to work with… I also felt like it was a little loose and rattly on the bike I tested (which was a demo model that goes to the Ebike Expo)
  • There’s a lot of high quality hardware on this bike including the belt drive, internal gearing, hydraulic brakes etc. but the price is pretty high at ~$5,700
  • The rack doesn’t offer pannier blockers or an obvious clip point at the bottom and can only support 15 kg vs. 25 kg on a lot of other racks I see out there
  • This isn’t a huge deal but I was surprised that the seat post was so short, usually they are 300 to 350 mm long but this one was only about 250 mm and I wanted to put the seat higher
  • This may be adjustable but I feel like the response time for power cutoff on the motor when you stop pedaling is a little long as shown in the video, Bosch feels faster and more responsive
  • The seat tube collar was unique and maybe not my favorite, it uses a vertical bolt and different wedge design vs. the horizontal quick release, I appreciate that it comes with a rubber cap and maybe that it is less vulnerable to theft?

I test-rode one of these but decided against it. It feels like a really well built, high quality product but I was put off by a few small points:

  • The high price.
  • I tried starting off facing up a steep hill and there was a good few seconds before I got any assistance and there is no throttle to help in this situation.
  • I live in Seattle where the transit buses have a bike rack on the front which can carry up to 3 bikes. The city is OK with electric bikes using the racks but there is a weight limit of 55 pounds which the Integrale exceeds. (Note it was quite hard to find this out because Kalkhoff annoyingly do not seems to publish the weight of their bikes).

Great points Tom, interesting to hear about the weight restrictions for ebikes on busses in Seattle… I was just visiting, great town! Many ebikes these days are in the 50 lb range… the Integrale does weigh more due in part to the higher battery capacity and accessories. I’m assuming you’d want fenders on any ebike you got given the rain? One of the big reasons I dig so deep for details on these reviews is that indeed, many companies do not list weight, stand over height etc. and even if I’m only looking at one of the four sizes, the weight should be fairly close. Appreciate you sharing your thoughts on the bike :)

1 year ago

Yes, fenders are a must for Seattle riding :)

I appreciate the details in your reviews Court, and the consistency. I don’t have the same priorities as you (eg I have never used a bottle cage) but having your reviews as a reliable baseline when comparing bikes is very useful.

Thanks Court for the great work you do here! With the help with your site and after test riding many myself, ended up buying an Integrale S11 in August 2016 (despite the fact I think you hadn’t done a full review yet). I really love almost everything about this bike and it was a pleasure to ride. But there’s more to share here…

I concur with everything Court mentions about this bike (Pros and Cons) in his review. A few other ‘pros’ to mention:

  • There’s a single-speed “walk mode” available if you hold down the ‘+’ button. This is very welcome because I have a steep sidewalk on part of my commute where riding is prohibited. Although the walk mode speed is more like a trot or jog speed, and I’m 6′, it’s still a welcome feature.
  • The charger is very light weight.
  • The lights work good, although some night commuters might want to supplement the front with something brighter if they ride on very dark paths, or super bright roadways for visibility. The front light can be aimed up and down a little on the fly, and more with tools.
  • The bike feels solid and offers a comfortable ride.

Cons. As mentioned in my story below, there are some things that I hope Kalkhoff improves:

  • I hope they devise a way to install a pannier front rack with at least three attachment points and goes over the fork. (A front rack that just clamps onto each side separately of the suspension fork tubes, is unstable, wobbles, and possibly even dangerous.)
  • The display should be delivered to US customers set to English. Without a manual, or speaking German, it was frustrating to figure out how to do that.
  • The license frame should be removed, or at least fully attached so it doesn’t bounce around.
  • The dealer should be instructed to make sure the rear internal gear hub is properly tested and adjusted before customer delivery.
  • The front fender needs a rain/mud flap. (Ok, I’m in Seattle, so this might not be applicable to those of you in dry zones.) Otherwise the sturdy fenders are great!

I ended up returning it in October after both the shop and the bike itself gave me a less-than-expected experience. I only had use of the bike for ~2 weeks during that two+ month time due to service challenges and delays with the bike shop. But I did mostly enjoy my 12km (7mi) Seattle commute a couple times. One of the issues was before purchase, the shop told me they could put a front low-boy pannier rack on it. (Riding with low boy bags in front is so much nicer and more stable than rear bags.) After an unstable wobbly front rack solution from the dealer, and then their proposal to custom manufacture something I gave up on the front rack idea, and them. Another issue was that the S11 rear internal hub was either defective or not properly adjusted from day-one ownership. It sometimes skipped, failed to shift, and made loud cracking sounds. The shop claimed it was not adjusted properly, …after telling me it was defective. I still don’t know. The shop did not properly prepare the display for delivery, did not have the correct owner manual, and left on a partially attached EU license plate accessory which rattled over every bump. I also later discovered the bike I purchased was over a year old (August 2015), yet they told me it was a 2016. (My bike shop experience should not necessarily dissuade others from considering this fantastic speed pedelec bike.)

I plan to purchase a different make/model that tied with this one in my research and test rides. I’ll report back after that. And thanks again Court. Every time I watch one of your road test vids I feel nostalgic for South Bay in So. Cal. where I grew up! Nostalgic, but I still love the Pacific Northwest. :-)

Hey Eric, that’s some GREAT feedback… you were objective and related that each shop works differently and I appreciate that. Interesting points about the front rack, the license plate holder and your experience getting the display set to English. Most of this was either taken care of or irrelevant during my tests and it’s the kind of feedback that can only come from real life buyers! I’m hopeful that Kalkhoff team USA will see it and maybe work more closely with their dealers in the future. I wish you luck with your next electric bicycle, whatever it may be ;)

I agree!

Ok, in Germany I heared that the warranty is longer ... but 2 years is also good. And that is the thing, all other manufacturers won't give another 2 years warranty on the changed drive unit. So if there is still a problem, you can be sure to get the motor replaced for free.

Motor from Aug. 2015? Give it a try - else you will get a new 2017 drive unit. So no risk - if the dealer is not that far away! The Kalkhoff Service is really good.

So buy it if the price is ok. Ask if you get another bike if your new one needs to be fixed.


Thanks for your help Alex. The bike shop is bringing one in that I think will fit my size. I have short legs and the Medium was a little too tall for standover height. The bike shop tells me that the integrale runs larger in sizing. I expect the small will fit well, and if so I'll get it. It's going to be fun to ride!

The Kalkhoff Integrale S11 looks like such a nice bike and has a lot of features (e.g. belt drive, internally geared hub, speed pedelec).
I agree!
He mentioned that there is a 2 year warranty, and if the motor needs to be replaced under warranty, the new motor would have a new 2 year warranty. The bike I was looking at had a motor date of Aug 2015 and was an Impulse EVO RS.

This is an overview of the current situation.
You can see here:
- number of registered motor systems
- mileage of all motor systems per type
- members year of purchase per motor system

There aro no failures in it. The failures are summarized in the "motors & statistics" section under each run time chart.

So buy it if the price is ok. Ask if you get another bike if your new one needs to be fixed.

Thanks so much for your help. I noticed that you are creator of that database. Great job! Looks like a very good resource. As I've been looking through it, I'm understanding a bit more. Google translate is pretty good!

The Kalkhoff Integrale S11 looks like such a nice bike and has a lot of features (e.g. belt drive, internally geared hub, speed pedelec). I talked with the dealer today about warranty and he says that Kalkhoff has been good on their warranty support. He mentioned that there is a 2 year warranty, and if the motor needs to be replaced under warranty, the new motor would have a new 2 year warranty. The bike I was looking at had a motor date of Aug 2015 and was an Impulse EVO RS.

I found the chart below in my searches. Is this yours? Is it showing reported failures per calendar year for each of the drive systems? I wonder if it's possible to find out how many of each of the drive units have been manufactured.

You mentioned that one user may being having issues with a torque sensor. Have you ever found a motor tear down on the web? I've looked and haven't seen any.

Thanks again!

Thanks for the responses. I'm looking at the integrale s-11. It is a 2017 model year bike and the local ebike shop is having a closeout sale on it. I will go back and look at the motor type and date. I've looked at the database that has been link and I think I need to understand it more. At first read it sounds like the entries in the database are from people who had some sort of problem with the bike. I will ask the LBS more about warranty and how the motor is serviced or replaced if I have problems. Has anyone with this bike in this forum experienced issues first hand?

My 2017 Kalkhoff Integrale i8 has developed a fault after using it for about 6 weeks/350 miles. From time to time, it switches off without clear cause. It is impossible to switch the bicycle back on immediately afterwards. If I leave it off for a few minutes, I can switch it back on eventually.

The first time this happened was on a rainy day, so I assumed at the time it was caused by water. But it has happened on dry days as well. When it happens, I am using a reasonable gear and the power output of the motor is not unusually high. However, it only seems to happen when the bicycle is providing pedal assist and never when my speed exceeds 17 mph and I'm on my own power.

The problem is very frustrating to diagnose. Most of the time, it seems as though the bicycle is perfectly fine and it does not switch off. I am unable to replicate the problem as it seems to occur at random.

Has anyone else had this experience?

Looking for a commuter for a 20 mile round trip commute in hilly terrain. My wife has a Stromer ST1 Elite that I like but with so much weight in the back it isn't the most balanced bike I've ever ridden. I haven't test ridden the Specialized as there isn't one local yet but the reviews intrigued me. Anyone know if the Stromer ST1 Elite battery is compatible with the ST1x? Any input, advice, or other suggestions appreciated.

Neither, get the Bulls Lacuba evo e45. It has better specs than the Stromer and Vado. I prefer the e45 over the Giant and the Integrale 11 too.
Call Brent at Great Western Ebikes, if you go in the store, he will work you a deal. btw, I own a Levo and an e45, so I have a dog in both fights. The e45 rides like a dream.

Been using my S11 to commute through central London for the past couple of months, clocking up about 36 miles a day. There's already a problem with the bearings in one of my pedals and my saddle is getting very noisy and wobbly.

Has anyone looked into changing their pedals and/or saddle? If so what did you go for?

Normally on a new bike I would fit clip on pedals but not sure they are relevant/desirable on my S11 - its a big, heavy bike to fall over with!!

I am in the Detroit area and I bought my ebike from Propel in Brooklyn. I really wanted to stay local but there just isn't much selection in my area. I was close to choosing the Trek XM700+ but the bike didn't fit me well. I have a local Focus/Kalkhoff dealer and I really liked the Integrale 11 speed. But that particular dealer didn't seem too concerned with getting my business inclusive of not returning a couple of phone calls. Also, I visited one local ebike shop that didn't seem very interested in helping me find the bike I wanted but rather only seemed interested in selling me on what they had on the floor. That dealer also let his bias against pedal assist bikes come out loud and clear when I mentioned a few makes/models I had researched. Finally, I visited a local traditional bike shop that sells some brands that also have ebikes like Scott or Felt (if I recall correctly). I inquired about the possibility of them ordering an ebike in one of those brands even though they only retailed traditional bikes. They steered the conversation to kit bikes and only seemed interested in building a kit bike for me (promising I could do 40mph on one of their kit bikes). So in summary, I had a really bad local experience on the shopping end (and conversely I found that Propel was eager to get me all the info I needed and respond to all of my silly inquiries). And I can report that now that I have had the bike for a few months, I've had it in to 2 different shops for brake adjustments. One is the Trek dealer where I almost opted for an XM700+. I have to say both places were very good about helping me out with service which was a pleasant surprise. It makes me optimistic that I can find someone to work on the bike should it become necessary.

I had a similar experience with one of my regular bikes. I did my research and kind of knew what I wanted but I couldn't find anything locally. I opted for a Spot Brand Champa because I was shopping for a steel frame city commuter with a belt drive. There were no Spot dealers near me so I purchased from a dealer in Chicago. The local Trek shop did the bike build for me, ordered and installed the fenders and now, over a year later, are building a front wheel/dynamo hub for me. So I have been pleasantly surprised that I've been able to get pretty good service from 2 different shops even though I didn't buy their bikes. Hopefully a good businessman sees those as opportunities to win customers if/when that customer decides to make another purchase.

This review was posted about a year ago. Any word on the reliability of the motor over the past year? I've heard there have been issues with the Impulse motor in the past and some people are reporting issues with the EVO motor that comes with this bike.

Solid Build so you get what you pay for also e Bikes are still new to the scene so MSRP is going to be really high due to demand levels being really low... Remember when the 1st computers and E Vehicles came out they where a lot of money but now you can get the new Tesla for 35k and a computer for 200-500 bucks, patience is a virtue so waiting on e bikes is ideal!!! even the DIY e bike kits are pricey so if your on a budget just wait it out!!!

How popular is the brand Kalkoff? i'm not sure how is going to be when this bike needs servicing. I would like all the motor choices however i really don't want to end up with a very heavy bike when the motor breaks. For instance in NL bosch is most popular but lesser brands like kalkoff is very rare.

So how long do those CDX "belts" tend to last? I ride through a lot of dirt and rain = wear on traditional chains.

I just bought the i8 version of this bike and it's incredible. I love the large display and the fact that it's permanently attached. No need to remove it every time you run into the store! Quality German craftsmanship. I already have over 200 miles on it. The only thing I changed was the seat. I swamped it for a Brooks real leather touring seat which added a lot for comfort.

Anybody know What's it like for a trailer? Like a Bob Yak? This bike is a rear hub. Others have a cassette with a pin which would be compatible with a bob yak, for example. Yes I know I should look up Bob Yak website, but does anyone know here? Have experience with them?

I'm giving serious consideration to one of these. However, the last few hundred metres to my place of work consist of a *very* steep hill. Can I assume that this bike would handle the daily climb? It's a very important factor in my decision to take the plunge (or not).

Try it and you buy it.

Hey man, I'm really liking your reviews - they are very educational and concise ! I'm really eager to see what the future brings for this industry, because even in smaller and less economically powerfull countries like my own the culture of e-bikes has grown really fast in the last couple of years.

One thing I dont like tho, and please dont mind me saying, it is the way you produce your videos. I wish less frames were hand held shots, maybe if you had yourself camera stand of some kind it would be much more eye pleasing to watch. I do believe so... I understand that you dont have a huge crew etc and you do this in a most efficient way on your own, these reviews. It is really appreciated.

Court, looks like a nice bike for long distance commuting, so might be a good option for me! How does it compare in terms of effort and feel with a Stromer or Bosch S-pedelec for cruising 25-28 mph?

I think it's comparable. It's easier to maintain higher speeds with the Stromer and the Bosch system is slightly more refined as far as power delivery.

Kalkhoff belongs to the upper class. It is a Mercedes at the eBikes. The price is high and the quality is also. Typical German. Thank you Court for the awesome video.

"A lot of this stuff is pioneered in Europe"; can confirm. Stromer is a latecomer compared to European markets, lol.

This was the only ebike I was going to buy here in the UK however because of the legislation about speed etc it put me off.... However I'm really shocked that the main distributor of the bike in the uk doesn't mention about what you have stated in the video about the speed settings for limiting them I'm going to look into the bike again as on our public roads I can select the limit and then off road use the higher speed. Thanks court

i love the bike! it does not look like an ebike. Btw how often do you have to replace the belt? i have no experience on belt drives and integrated geared hub. looks very sturdy and requires little maitenance

These belts are similar to car engine timing belts. I replaced the timing belt in my 18 year old Accord with 90,000 miles on it and it was indistinguishable from a new belt.

Court the motor should be 350watt .

my favourite brand even though they seem to use that colour on the top range stuff they must have tons of the stuff.
