Product Details

Kalkhoff Agattu 3.I Dynamic 2019 Step Through Electric Bike

This super comfortable, German engineered, fully equipped e-commuter bike is designed to take the strain out of cycling, leaving you to enjoy the freedom and the fun.

Impulse Evo power-assist

Impulse Evo 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 Evo drive unit is mounted at bottom bracket level (the strongest part of any bike) to power the crank along with this the motor has a built in shifter sensor which cuts the power when shifting to relieve stress on the motor for a longer life span!

The Battery

The iNext Li-Ion 36 V 17,5 Ah (621 Wh) battery offer a huge capacity allowing for longer run time which equals more fun out of the bike! Up to a maximum possible range of 205 km (at the lowest assistance level, under optimal conditions, with a fully charged battery in perfect condition and with the highest possible capacity.)

  • 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
  • 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 - this bike has the muscle to help you up the steepest climbs

The bike itself

  • Svelte German-engineered aluminium alloy frame
  • SunTour suspension forks help smooth bumpy roads and tracks, as does the suspension seatpost
  • Tektro T285 hydraulic disc brakes offering balanced and effective stopping power why this is a advantage
  • Shimano Deore 1x10 speed drivetrain offering a great balance of gears to gain maximum assistance from the motor
  • Full length mudguards and chain guard keeps the sleek frame dryer and cleaner
  • Rolls on durable, puncture resistant Schwalbe 700x38 tyres to make it more practical

Get connected

The display includes a USB port so you can charge your smartphone.

Smart Display

On-board computer and navigator: Both the Bluetooth module and the USB port allow you to connect up your smartphone.

The perfect guide

Free for iPhone and Android: navigation system based on tried-and-tested software.

Gear shifting under load

An adjustable shift-sensor interrupts the motor's assistance for a fractiion of a second to enable lower-wear shifting.

One for all

One key is enough: The keyed alike locking of frame and battery lock makes handling easier.
