Kalkhoff Jubilee Excite I7 2018 Step Through E-Bike

The Jubilee Excite I7 is an urban city e-bike made especially clean with its Shimano Nexus hub gear and its Gates belt drive and especially long range with its high capacity 603Wh battery.

Gates Belt Drive
The carbon fibre-reinforced rubber belt lasts much longer (15,000-20,000 kilometres) than a steel chain, it's much lighter, it won't stretch and will never rust so you will never need to lube it. The absence of oil means the belt doesn't attract dirt the way that even a well-maintained steel chain might.

Gates (who have been based in Colorado for over 100 years and who also manufacture in Dumfries, Scotland) are the world leaders in timing belts for cars. They worked in close collaboration with Wayne Lumpkin (founder of Avid brakes) in the development of their Belt Drive system. You can be confident that this technology has been precision tested.

Shimano Nexus 7-Speed Hub Gears
A belt drive transmission can't be derailled, so if you're looking for a multi-geared belt drive bike you need a hub gear transmission. Here, Kalkhoff spec the tried and tested Shimano Nexus 7-speed hub.

  • As with every hub gear, the Shimano Nexus gear change mechanism is protected from the elements inside the rear wheel’s hub
  • You can change gear whether you’re pedalling or not, moving or stationary
  • With a 244% difference between top and bottom gear (equivalent to an 11-27 cassette) the Nexus 7-speed hub offers a decent range of gears for mostly urban use
  • Hub gears are almost always cleaner, lower maintenance and longer lasting than derailleur systems
  • Add belt drive and Magura hydraulic brakes to the mix and you have one extraordinarily reliable, clean machine

Impulse 2 power-assist motor
You can buy the Kalkhoff Jubilee Excite I7 confident in the knowledge that Kalkhoff have sold over 400,000 e-bikes featuring its German engineered Impulse motor drive.

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 city/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
  • 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
  • This 80Nm torque motor has the muscle to get you going from a standing start up a steep incline
  • 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 603Wh Impulse battery is one powerful fuel tank capable of powering the motor up to 100km on mixed terrain and will be good for over 1,000 charge cycles
  • The battery fits neatly behind the frame seat tube
  • Walk mode comes in very handy if you ever have to push the bike - say up one of those bike ramps thoughtfully located beside stairs
  • In compliance with EU and UK law, this e-bike is a pedal bike with up to 250W power assist, which cuts out once you reach 25KPH (15.5 MPH)
  • This limiter doesn't prevent you going faster 'the old way' - by pedalling harder

The Bike Itself

The bike itself is an especially clean take on the Euro trekking bike theme. That is, its a fully equipped commuter/hybrid bike equally at home on smooth roads or rough tracks.

  • Magura hydraulic rim brakes offer the cable-free, low maintenance performance of hydraulic disc brakes in a more familiar rim brake format
  • SunTour suspension forks help smooth bumpy roads and tracks
  • The wheels roll on durable, puncture resistant Schwalbe 700x38 tyres
  • The bike is fitted with full mudguards and chainguard to help you stay clean
  • It also comes with a rack to carry panniers
  • Then it's fitted with a heavy duty kickstand for easy parking when there's nowhere convenient to lean the bike
  • 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
