Kalkhoff Pro Connect i9 Electric Bike
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 11Ah battery that gives up to 60 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.
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.
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.
