Product Details

Kalkhoff Pro Connect B9 Men's 2017

The Kalkhoff Connect B9 is a fully equipped, proven best buy, Bosch-powered, German-engineered urban/trekking/hybrid electric bike.

Kalkhoff are respected as the number one manufacturer of electric trekking/hybrid bikes in their native Germany. That's a significant accolade when you consider that Germany is Europe's biggest and most discerning eBike market.

Kalkhoff's German neighbours Bosch are among the world's most respected and most experienced manufacturer's of e-bike engines and batteries. If you're looking for a great-performing, reliable, all-rounder electric bike, a Bosch-equipped Kalkhoff Pro Connect B9 is an excellent option.

  • With up to 63Nm torque the Bosch Performance Cruise Motor will indeed have you cruising up the steepest inclines
  • The bar mounted Bosch Purion LCD display/control panel (AKA computer) makes it easy to select the level of power assist required
  • You can choose from four levels of power assist: Eco 50%, Tour 120%, Sport 190% and Turbo 275%
  • Even in Eco mode, the Pro Connect fulfills the e-bike promise - it feels like you're always riding with a tailwind
  • The computer also keeps you up to speed with the battery's charge status and expected range based on the mode you're currently riding in
  • This 'range assist' estimate gives you early warning when to switch down to Tour or Eco mode to help ensure you enjoy power assistance all the way to the finish of the ride
  • The Bosch Purion also displays regular cycle computer data - speed, trip distance and overall distance
  • Kalkhoff quote 150km battery range in eco mode in perfect conditions (flat roads, hardly any wind)
  • This translates as around 40Km / 25 miles range in Turbo mode when riding into headwinds over the most challenging terrain (when you especially appreciate this bike's Bosch-powered assistance)
  • The Bosch Performance Line Li-Ion Battery is fitted to the down tube
  • The battery will be good for at least 600 recharge cycles
  • Like every electric bike we stock, the Kalkhoff Pro Connect B9 is a pedelec electric bike with up to 250W automatic power assistance, which kicks in when you pedal and cuts out once you reach 25KPH (15.5 MPH) in compliance with EU and UK law
  • This limiter doesn't prevent you going faster 'the old way' - by pedalling harder or by riding downhill
  • If you ever hanker for more vigorous exercise, the Kalkhoff Pro Connect B9 is rideable with zero power assist

Centre Drive

  • The Bosch Power 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

The Bike Itself

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

  • Smooth, welded, e-bike optimised aluminium alloy frame
  • The SunTour suspension fork absorbs shock when you ride urban cobbles or countryside trails
  • Quality hydraulic disc brakes - why you want them
  • It rolls on durable, extra puncture resistant Schwalbe 700x38 tyres
  • It comes fitted with full mudguards, a pannier rack, a kickstand and lights
  • The front light is bolted onto the fork crown, the rear light to the rear pannier rack, so they're always on the bike when you need them
  • These high-quality LED lights are powered by the bike's Bosch battery so you won't have to think about changing or charging the batteries as you do with most bike lights
  • The Shimano Alivio 9-speed Rapidfire gear shifter and rear mech are as smooth-working and reliable as we have come to expect from mid-range Shimano gears
