Finish and function in perfect harmony

Why does the Kalkhoff Include turn so many heads? Because state-of-the-art drive technology is integrated seamlessly into the frame developed especially for the system. Because the new Impulse Evo drive system fulfils the highest standards of performance and efficiency. And because we make no compromises across the entire model range – whether in design, operation, riding enjoyment or safety. And that’s precisely why the Kalkhoff Include is the best reason to get mobile.

In the beginning there was a challenge: to develop THE comfort e-bike that exudes elegance, has sufficient power, is easy to operate and at the same time ensures a relaxed riding experience. Without having to compromise on details or drive system. The result is the Kalkhoff Include. Whether you choose belt or chain drive or freewheel, diamond or step-through frame or a sporty ladies’ model is your decision. But one thing is certain: it will more than fulfil your expectations.

The perfect combination of e-bike and frame technology has a name: Impulse Evo. Developed for the new e-bike generation, the Impulse Evo drive system is ground-breaking in terms of innovation, integration and networking. The holistic design of motor, frame and components is what makes the difference. And the result is unique: we offer you a skilfully engineered e-bike drive system with the ideal blend of design and functionality, manufactured entirely in Germany. At the same time, you enjoy important extra benefits: more power, more efficiency and more innovative ideas.

Positioning the battery behind the seat tube is a tradition at Kalkhoff because it gives the bike a better centre of gravity, and thus offers a considerable advantage in terms of riding stability. What’s new, on the other hand, is the elegant look achieved by its perfect integration into the frame construction. This is achieved by our consistent implementation of the concept of component integration. And along the way, we have also optimised the handling of this long-distance power supply.

  • Thanks to the generous 17 Ah capacity, the Impulse Evo battery can cover distances of up to 125 miles in ideal conditions
  • Moving the battery lock to the top makes unlocking and removing the battery considerably easier.
  • The charging socket also acts as a service interface, making system updates much more convenient.

Your smartphone is safely stored in your pocket, and yet the navigation instructions are constantly visible. Thanks to the Impulse Evo navigation app, based on the tried and tested Naviki software, and Bluetooth connection, the Impulse Evo smart conveniently displays the route to your destination. And the USB charging socket ensures you stay powered up if your smartphone’s battery runs out.

  • Standard displays: Speed, remaining range, battery level, assist level, assist bar, clock
  • Selectable displays: Average tour speed, tour kilometers, tour time, maximum trip speed, average trip speed, trip kilometers, trip time, cadence, total kilometers
  • Navigation displays: Directional arrow, road name, distance to next change of direction

Hydroforming, die casting, extrusion – with the most modern manufacturing technology, we create e-bike frames that set new standards. In other words: we create the ideal combination of integration and innovation.

  • Clean: the Kalkhoff Include premium models are equipped with a low-maintenance belt drive.
  • Smart: previously a bit of an eyesore, now elegantly integrated – the frame lock is now incorporated into the rear triangle design.
  • Strong: the pannier rack is designed with the Snap-it system for easy fitting of accessories and child seats.
  • Simple: the ergonomically designed easy-reach control unit is simple to operate without letting go of the handlebars.

These bikes have revolutionised our cycling enjoyment

by from Dorset on

My husband and I were becoming more and more aware of ageing bones and steep hills and windy days which were spoiling our cycling enjoyment! The decision as made to take the leap to electric bikes and careful research led us to Kalkhoff at 50 Cycles, Shoreham. Charles Martin was extremely helpful with his advise and encouraged us to take two models out for a test ride. We both fell in love with the Include Premium Belt- step through. The comfort has to be experienced to believe, the performance is superb and build quality is exceptional. We are both so proud of our bikes and are finding every opportunity to sneak off for a ride. These bikes have revolutionised our cycling enjoyment. Thank you Kalkhoff, thank you 50 Cycles and thank you Charles.

New Wheel's Video Review

Best ever

by from Northamptonshire on

I absolutely love this bike. I've had a broken foot for months and not been able to do my usual trekking pastime so felt quite low at not being able to exercise. I've been looking for an electric bike for a long time and with the help of 50 cycles staff I chose this one. It was delivered quickly and unable to wait until my foot healed I decided to try cycling and it's brilliant. I have freedom again and at last feel like I have my indipendance back too.

Don't get me wrong you have to work with this bike but if you're struggling with a hill then it will give you a bit of help. I love that I can turn the battery off all together and that I'm getting some good exercise and freedom. Plus, with a partner who cycles a lot I can at last go out exploring with him and enjoying the fresh air too.

Fantastic Powerful Ebike

by from East Sussex on

Bought this top of the range bike in September. It was really to help in going uphill, as I have knee problems. It is great for that, you can feel the surge of power as you pedal up! It is also great on the flat, reaching high speeds easily (not more than 15mph on roads of course). I can now leave my husband far behind and not be out of breath! Knees are fine too. Gears are smooth, computer easily understood. The bike is solid, safe and comfortable. You still get a good work out. Expensive, but you get what you pay for.
