Key Features

  • Svelte German-engineered aluminium alloy frame
  • SunTour suspension forks help smooth bumpy roads and tracks, as does the suspension seatpost
  • German-engineered Magura brakes bring you the smooth, high-performance, low-maintenance benefits of hydraulic disc brakes in a familiar rim brake format
  • Shimano Nexus 7-speed internal hub gears are cleaner, lower maintenance and longer lasting than derailleur systems
  • The Nexus twist grip gear shifter allows you to select any gear with a single sweep
  • You can change gear whether the bike is moving or stationary and whether you're pedalling or freewheeling
  • The chainguard and mudguards continue the clean theme
  • Rolls on durable, puncture resistant Schwalbe 700x38 tyres to make it more practical
  • Fitted with pannier rack and kickstand
  • The front dynamo hub powers the high quality front and rear LED lights, so no light batteries to replace or recharge, ever
  • Unlike some dynamo systems, the lights have a standlight feature, so they stay on when you stop at the traffic lights
  • These lights are bolted onto the bike - the front at the fork crown and the rear on the back of the pannier rack - so you'll never be caught out without lights

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 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

This Advanced model offers the larger capacity 603Wh / 17Ah which in turn will allow a longer run time of up-to 205km (depending on rider and conditions), this of course means longer run times between charges and allows for longer rides!

  • 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 205km range based on best possible conditions
  • 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 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
