The Pro Connect has been a best seller for many years and for good reason. This years 9 speed model is powered by Kalkhoffs Impulse 2.0 centre motor and a 36 volt 15Ah battery that gives up to 90 miles range. It's superbly well-equipped with Shimano Alivio gears, Shimano hydraulic disc brakes, front and rear lights, new illuminated handlebar controls, puncture-resistant tyres, integrated mudguards and suspension.

Impulse 2.0

Providing an enormous 70Nm torque and working with the gear shifter to provide seamless transmission it's the most capable crank drive unit around. Kalkhoff have engineered a more powerful, efficient, quieter motor that supplies massive assistance from a standing start and cuts all hills down to size.

Shift Assist

A genuine innovation - every time you change up or down a gear, power drops away for a matter of milliseconds for optimal gear shifting. This does a number of great things - it extends your gears mechanical lifetime, feels satisfyingly natural and makes for a smoother application of all that power. They had to invent a litte electromechanical gadget to detect gear changes that worked with the motor. They succeeded and the result brings a new feeling of confident power to riding a Kalkhoff electric bike.

Shimano hydraulic brakes

It's been some years since Kalkhoff dropped cable-pull brakes on their most popular models. The Shimano Acera M396 disc brake boasts an efficient design to ensure powerful and controllable braking. It features a fully hydraulic 2-piston unit with automatic pad adjustment, aluminium levers, and resin pads that complement braking power. Also, rather than using hydraulic fluid it uses Shimano mineral oil for better performance and safety.

Front and rear lights

Powered by a free-running Shimano hub dynamo, the lights on this and all Beat bikes are excellent. Few bikes on sale in the UK benefit from front and rear illumination of this quality and utility.  The rear lamp's integrated steady light function offers another 4 minutes of light while at a standstill, for added visibility when waiting at lights or junctions seen from behind and also from the side to crossing traffic.

The front lamp casts 30 lux of cool, bright LED light forward, enough to make night rides across the park something to enjoy rather than endure.

Other winning features

  • Compact multifunction LCD console - Speed, Charge, Assistance Level, Total Miles, Trip Miles
  • Handlebar-mounted control - illuminated with Walk Assist button, on/off, power controls and options.
  • Suntour NEX alloy forks
  • Shimano Alivio 9-speed derailleur gears
  • 540 Wh Lithium tri-metal battery
  • 1100 cycle battery lifetime, more than twice that of the Bosch battery. So 50% extra capacity and 120% extra lifespan.
  • Schwalbe Energizer Life puncture resistant tyres, especially made for E-Bikes.

My ageing knees at 68 are failing a little after lifetime of cycling. This is my first electric bike and I find it amazing. I now tackle our local steep hills with total ease and parking in town is a doddle. My wife so impressed, and has now bought the trapezoid model for herself. This has got to be the future, no more struggling for the decreasing number of car parking spaces in our small town! 50cycles have been very helpful from order, purchase and prompt delivery with after sales help when required. Extremely happy in all aspects.

I am a 70 year old and have been cycling with a local club since retiring 3 years ago. I was looking for an electric bike mainly for the fun of it. In October 2015 I bought a second hand Kalkhoff Sahel Nuvinci. In January 2016 I saw a Pro Connect 9G on the used bikes page of the 50 Cycles website.

This was the one I really wanted, it was an insurance claim, a new machine at a very reasonable price. As of October 2016, I have done 2600 miles. I ride mostly in Eco mode, using the higher settings only on the stiffest Derbyshire hills or when I want a bit of fun on the way home. My average journey is 48 miles, 3 led's on the battery indicator. The range works out 80 - 85 miles. I discarded the pump, preferring my own. I removed the riser stem and installed a Deda road bike stem to give myself a sportier position. I have replaced the saddle with a Brookes flyer - the one with coil springs and I have fitted pedals with SPD's on one side so I have the option of clipping in or riding in standard shoes. The bell trigger broke on the second ride, I now have a pinger bell.

There was initially some occasional graunching noise coming from the chainwheel area. On investigation, I found the chainwheel had not been deburred after pressing and suspect in certain gears, when the chain was particularly off centre it may have been catching. Having filed away the burrs, it seems better. At 1500 miles, I replaced the brake pads. At 2100 miles I bled the rear brakes as the lever was spongy. 2250 miles, fitted a new chain, I used two Sram 9sp chains as desribed by another reviewer. At 2350 miles I had to tighten the cassette which had become loose.

The bicycle is a stable dependable machine, a delight to ride, even Winnatts Pass is do-able. It's quite a heavy bike compared to a road bike, occasional riding without the motor will keep you fit and you certainly know when you have reached 16.5mph and the motor cuts out as you speed uphill. If you are alway at the back of the ride, struggling to keep up, just get one of these. You will have more fun and your clubmates will thank you. Since I bought the bike, one other club member has bought one and several members have fitted power kits to their bikes. I still ride at the back on club rides, as sweeper, laden with tools and spares.

I can't begin to describe how happy I am :)

Pedelec is great, really pleased with it. German engineering at its very best, really well made, everything about it oozes quality. Handover was good when I collected it, all checked over and set up and helpful hints and tips on battery etc. I have various digestive issues which means I can't eat enough to maintain my weight if I burn off too many calories on long bike rides on a standard bike. So this is going to be a life changer for me, can't begin to describe how happy I am :)
