The Agattu has been a best seller for many years and for good reason. This 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.

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 2.0 maintains assistance even after the hill starts to level out as you reach the top. It's a a nice touch that makes for happier hill-climbing and unique to Kalkhoff. 

Shift Assist  is 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 litte 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.

Magura hydraulic brakes Magura's hydraulic 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.

Impulse LCD - on-board computer The elegant back lit ergonomic control panel gives you full control over the Impulse electric motor allowing safe operation without having to take your hands off the handlebars.

The following functions are available:

Assist level
Battery charge state
Trip distance
Total distance 

Front and rear lights PPowered by a free-running Shimano hub dynamo, the lights on this and all Kalkhoff bikes are excellent. Few bikes on sale in the UK benefit from front and rear illumination of this quality and utility.  The rear lamp's integrated steady light function offers another 4 minutes of light while at a standstill, for added visibility when waiting at lights or junctions seen from behind and also from the side to crossing traffic.

The front lamp casts 30 lux of cool, bright LED light forward, enough to make night rides across the park something to enjoy rather than endure.

  • Multifunction LCD console - Speed, Charge, Assistance Level, Total Miles, Trip Miles
  • Handlebar-mounted control - illuminated with Walk Assist button, on/off, power controls and options.
  • Adjustable alloy forks
  • High-end Nexus 7-speed gears

Took a long time but best decision I've ever made

by from Stock Village Essex on

Bike received Saturday 09/04/16 from 50 Cycles Richmond Branch. The front tyre was flat and the seat, handle bars and grips had to be set up by me for me, but other than that all very perfect. I went out the front door to test the bike and quickly returned as it was raining quite hard. Sunday morning I’d planned to visit my son in Stanford le Hope, Essex and my daughter in Orsett Village, Essex. I pumped the front tyre up, packed my paniers and set off.

You need to know that I am a 63 year old, semi keen cyclist and tipping the scales at 11.5 stone. I had not cycled for over a year and my usual trusty steed is a Dawes Giro 600 racing bike that even I can pick up with just two fingers. I really noticed the weight of the bike and the different riding position, racing bike down and forward, Kalkhoff upright and pushing through the “buns”. Needless to say I had a huge grin on my face, happy to be back in the saddle and happy with the confidence the power assist gave me. I had a great day and my family enjoyed their trial cycles and they both congratulated me on my choice of bike.

My observations on the difference between my trusty racing bike and my new Kalkhoff are that the Dawes is good for local sprints but my new Kalkohof is a work horse and gives me confidence that I will get up that hill and I can pull away from that junction without being any hindrance to the local traffic. Bottom line is I know I have made the right decision for me at my time of life. I am looking for this bike to take me into my seventies and I am fully confident that it is capable of that request. Happy to answer any question, contact details l_s_anthony@yahoo.co.uk

Great bike

by from Holmfirth on

This is a great bike - beautifully built. Comes complete - packaging amazing and only had to add the pedals. It's heavy but you don't feel that because of the pedal assist and that is essential for managing the hills in the south Pennines. It manages the steepest of hills without having to get off and walk but also gives you the exercise benefits of cycling. I wish I had bought one years ago.

Very Good Experience

by from Bristol on

I bought the bike in February and have waited to write this review until I had used the bike for a while. My first impressions, which were that the bike was brilliant, have been borne out. I love it. I don't have a car out of choice and this bike has made my life easier. It has increased my range, it carries heavy stuff, it is comfortable to ride on rough city roads and it makes hills easy. I reckon this is the way forward if we are to have less congested cities. The service I received from 50cycles Bristol was excellent.

So why four stars and not five? I paid extra to upgrade the battery, and I find that the miles I get from it are substantially below the headline figures on the website. I was warned that this would be the case but it is less than half the mileage on the headline figure. It's not a real problem for city riding but I wanted potential buyers to be aware that if you live somewhere hilly you may well need the battery upgrade. [e.g. this Agattu 7G comes with a 14.5Ah battery]

Agattu 7g

by from Devon on

Over the moon with the bike, spent along time deciding which bike to get, asked lots of questions and had very quick professional replies from staff at 50 cycles. The bike arrived very quickly, easy to put together and I was able to ride on the same day! Brill! I would not hesitate to recommend the bike and 50 cycles.

Review of Kalkhoff Agattu

by from Shoreham on

What an amazing bike, I've had this for a month now and thoroughly enjoy cycling it. It really makes light work of cycling in head on wind, even in the wind and the rain I've used it to commute to work every day. Charles at Shorham has so much knowledge on all the bikes and he quickly identified the right bike for me without the pushy sales pitch. There's also some great routes to take from the shop to test drive the bikes too. I love my bike, everyone needs at least one e-bike in their life.
