Kalkhoff Agattu i7 Electric Bike 
 
This super comfortable, German engineered, fully equipped e-bike is designed to take the strain out of cycling, leaving you to enjoy the freedom and the fun. 
 
Impulse 2 power-assist 
Impulse 2 is Kalkhoff's own Centre Drive system, designed and manufactured in Germany where Kalkhoff are respected as the number one manufacturer of electric trekking/hybrid bikes. That's a significant accolade when you consider that Germany is Europe's biggest, fastest growing and most discerning eBike market. 
 
The Impulse 2 drive unit is mounted at bottom bracket level (the strongest part of any bike) to power the crank (in contrast with most e-bikes which are front or rear wheel hub drive). 
Most riders find Centre Drive power assist feels more natural than a hub-drive system. 
With the motor low down at bottom bracket level at the bike's mid point, the bike feels better balanced than an e-bike with the motor on the front or rear hub. 
With its lower centre of gravity a Centre Drive e-bike feels more stable. 
The battery is neatly integrated behind the frame seat tube. 
Wheel fitting/removal is much easier when the motor is central rather than wheel driven. 
Up to 150km range. 
Shift-sensor technology - the power assist cuts out for a fraction of a second when you change gear to prevent the jarring that can occur when you shift under load. 
70Nm torque. 
The classy Impulse bar mount computer has an easy to read LCD display so you can keep an eye on battery level, power mode, speed, trip distance and odometer. 
The Impulse battery will be good for over 1,000 charge cycles.
