Video Review: Kalkhoff Agattu Electric Bike

The Kalkhoff Agattu i8 has become one of the most popular bikes at The New Wheel, and it’s no surprise to us. It brings together a number of features and trends that have set Kalkhoff apart over the years: great handling while being upright and comfortable, an excellent and reliable pedal assist system, top quality components across the board. To top it all off, the 2014 Agattu now sports the Impulse 2.0 drive system, a huge step forward for middle motor technology that offers not just more power than the original Impulse system, but less noise, smoother shifting, and a more customizable ride feel.

The central feature of the Agattu is actually a number of components that lend a comfortable, sturdy ride feel. First and foremost is a handlebar arrangement that allows you to sit up very straight and upright. A swept back bar combined with ergonomic grips is not just good for your back and shoulders: it also allows for increased visibility when riding in the city. A large gel saddle atop a suspension seat post will minimize shock and vibration when riding on less than stellar surfaces. Finally, a suspension front fork with new larger stanchions make the ride not just more comfortable but also safe, as the unexpected pothole can be simply rolled over.

The component spec of the Agattu beyond the comfort features is also top notch. The uber reliable Magura hydraulic rim brakes not only will stop you on a dime but are also extremely quiet with pads that last a long time up and down steep San Francisco hills. A Shimano Nexus 8-speed hub is all you need to tackle the steepest hills, and cruise up to 20 mph on the flats. Not only does it give you a great range of gears, but like all internally geared hubs, it’s reliable and simple to use. The tires are top-end Schwalbe Marathon tires with a thick puncture resistant belt. Finally, the bike comes standard with an integrated, light up the night front light, a rear light with a braking sensor, fenders, a rear rack and an integrated rear wheel lock.

As for the electric system, the 2014 Agattu has the brand new Impulse 2.0 motor system. We have a whole article on what makes this drive special, but when it comes to the Agattu, what the Impulse 2.0 motor system brings is climb up a wall torque, rock solid reliability, and smooth shifting and operation thanks to the revolutionary integrated shift sensor that turns off the motor for 300 milliseconds to allow your internally geared hub to shift into gear.
