Description

The Agattu has been a best seller for many years.

The perfect all-round electric bike returns with more power, improved controls, longer range and better performance. Hills, tracks, trails and national parks handle just as well as cycle paths, busy roads and parks in the city. It's powered by the Impulse 2.0 centre motor and a 36 volt 17Ah battery that gives up to 125 miles range. It's superbly well-equipped with Magura hydraulic brakes, front and rear lights, new illuminated handlebar controls, puncture-resistant tyres, integrated mudguards and suspension.


Kalkhoff Impulse 2.0 Providing an enormous 70Nm torque and working with the gear shifter to provide seamless transmission it's the most capable crank drive unit around. Kalkhoff have engineered a more powerful, efficient, quieter motor that supplies massive assistance from a standing start and cuts all hills down to size.

Climb Assist is another clever feature Kalkhoff's engineers have baked into Impulse 2.2  maintains assistance even after the hill starts to level out as you reach the top. It's a nice touch that makes for happier hill-climbing and unique to Kalkhoff. 


Shift Assist A genuine innovation - every time you change up or down a gear, power drops away for a matter of milliseconds for optimal gear shifting. This does a number of great things - it extends your gears mechanical lifetime, feels satisfyingly natural and makes for a smoother application of all that power. They had to invent a little electromechanical gadget to detect gear changes that worked with the motor. They succeeded and the result brings a new feeling of confident power to riding a Kalkhoff electric bike.


Carbon Belt Drive If you've bought a bicycle in the past 120 years, chances are it’s been powered by a chain. While the trusty bicycle chain has done every cyclist well, now the Gates Belt Drive is stronger, quieter and requires less maintenance. It’s grease-free, oil-free and hassle-free. It won’t leave any marks on your pants and you’ll never have to pull over to fix a dropped chain. The belts are one continuous loop – an inner carbon fiber tensile cord layered with polyurethane teeth and a nylon outer coating. Belts will not rust. This means that you do not need to worry about riding in the rain, or leaving your bike outside. Unlike chains, there is no need for lubrication and on average they last 3 – 4 times longer than a conventional bike chain.


Magura hydraulic brakes The piston design makes braking easy, well-modulated and reliable over time. There are no cables to stretch, the whole surface of the brake pad is applied to the rim (protecting both), pads last for ages and braking is strong and sure-footed. Looks cool too, with strong arch and neat braking assembly tucked against the forks.

 


Front and rear lights Powered by a free-running Shimano hub dynamo, the lights on this and all Kalkhoffs are excellent. Few bikes on sale in the UK benefit from front and rear illumination of this quality and utility.  Not only that, the rear lamp with remain lit for several minutes at standstill, for added visibility when waiting at lights or junctions.

The front lamp casts 80 lux of cool, bright LED light forward, enough to make night rides across the park something to enjoy rather than endure.

Ratings and Reviews

We have cycled on far more occasions than we ever did before

by from Chesterfield on

Hi, we bought 2 Agattu Premium Impulse 8 bikes a year ago and have loved them. We have done trips of over 40 miles several times, mainly on trails, with ease. Last week I rode to the coast on mine, on road all the way, taking my wife's battery with me as well. Even after a years use, my battery took me 62 miles before I had to swap them. I completed 73 miles with ease. Not bad for a 62 year old! We would both recommend Kalkhoff bikes, they have been both reliable and comfortable. They take the pain out of cycling and we have cycled on far more occasions than we ever did before. Thank you, David.

The best buy I ever made

by from Halesworth, Suffolk, UK on

I bought my Agattu Premium Impulse 8 in early April 2015. I am 77 years old and I have never been able to take any form of exercise purely for the sake of fitness - it has to be fun! This bike gives me the most comfortable and enjoyable ride I have ever experienced. It has opened up a wide area of beautiful countryside for me to explore and brought friends within easy reach. It is no exaggeration to say it has transformed my life. This is a top quality machine, built to last. I had some minor issues and queries soon after delivery, but these were sorted out quickly by friendly and efficient staff at 50 Cycles.

Perfect for my commute

by from North Yorkshire on

I have wanted to commute on a bike to work for years but although it's only 4.5 miles, it's very hilly. i did try some years ago on a conventional bike and it was just not feasible regularly. I arrived covered in sweat needing a shower and a change of clothes. As a female - this was just too hard!

I've been hearing about electric bikes for a few years but didn't really know what was out there, but at Christmas my husband said maybe we should start looking. My first search turned up Kalkoff's and from there I was convinced this would be the bike for me. Seeing people talking about biking in the Lake District reassured me that there would be enough power for the Yorkshire Dales.

After a trip to Loughborough where the staff were hugely helpful without putting any pressure on us, we ordered the Agattu, and it arrived the very next day. What can I say that hasn't been said by others? I LOVE my bike!! I have been riding it now for two weeks back and forth, and being able to use it as transportation is the greatest thing in the world. I jumped on it the first day and made it to work without a problem (being in pretty terrible shape!).

As the days go by I can already see that I'm using the 'power' setting less and getting in better shape. Instead of it being a long hard slog - it's a pleasure and I wake up every day excited about my ride into work. What took me 10 minutes in the car is only 20 minutes on the bike - and this is in no way pushing to get there quickly. While it's great exercise - I'm certainly working hard enough - I am not having to kill myself and can go to work in the clothes I'll wear for the day. My only regret - like others - is that I didn't get this years ago. It's simply superb!!
