“As we have come to expect from Rennstahl, each component is in perfect harmony with the others.”

“Cycling is healthy, it delivers oxygen to the brain and sharpens the senses”, sang M. A. Numminen in his song Fahrrad fahren ist notwendig. The Finn is as effective as anyone at conveying the benefits of cycling. And these benefits are increased yet further by e-bikes. The pedals turn more readily and it’s easier to enjoy your environment. So the Rennstahl 853 E-Tourer Pinion is the perfect partner for the daily commute, as a power unit for pulling a child-trailer, or for being able to increase your range on day rides and longer trips. This all-rounder is solid and dependable.
The frame-mounted Pinion gearing system is an exceptional piece of engineering. Like almost all elements of the bike, it’s made in Germany and it contributes to making the bike almost maintenance-free. Three versions are available, with 9, 12, or 18 gears, allowing the bike to be built to specifically suit its intended use.
The drive belt is similarly almost maintenance-free and exceptionally durable, available as an optional alternative to the conventional chain system. And the frame’s sliding drop-outs allow 650B and 700C wheels to be used interchangeably, to give either off-road cushioning or reduced rolling resistance on-road, without affecting the wheelbase. This means that the bike’s handling remain unchanged when switching wheels.
The frame geometry, with its sloping top tube, provides plenty of leg-room and allows the bike to be set up in a number of ways, to give riding postures ranging from sportily stretched out to more comfortably upright.
The aluminium components for the gearing system and lighting are matched colour-wise, for an attractive aesthetic. The Go SwissDrive hub motor and torque sensor are similarly protected, in a rock-solid aluminium housing. The system incorporates an integrated controller that allows the torque sensor to function maintenance-free, contactless and with no need for external sensors. The motor is brushless, and features low freewheeling resistance.
The frame has been designed specifically for the Pinion gearing system and uses “air-hardening” Reynolds 853 steel; before painting it is given a protective coating using cathodic electro deposition, which makes it exceptionally resistant to corrosion. The matching steel fork has good vibration-absorbing characteristics, increasing ride comfort, and the 50mm head tube ensures front-end stability. The adjustable drop-outs make it easy to fit either 650B or 700C wheels. In addition to the standard Syntace-based build, a Titanium package is available, using Falkenjagd components. And the Tune Components option features a range of different anodised colours.
The 853 E-Tourer Pinion is fitted with a Supernova front light, Tubus rear rack and low-riders and SKS-Bluemels mudguards.
The GO SwissDrive rear wheel motor provides powerful acceleration, high elasticity in response to terrain variation, substantial power reserves and quiet operation. With a nominal power rating of up to 500W (peak: approx. 1000W) und 40Nm of torque, it sets the standard for direct-drive motors. In addition, the power is applied where it works best: directly to the rear wheel hub. This means there is no increased wear on the drivetrain, it combines perfectly with the Pinion system, and you can scarcely hear it: at 18-25dB, it’s as quiet as a whisper. Another benefit is the energy recovery capability: on downhill sections, the KERS (Kinetic Energy Recovery System, familiar from Formula 1 motor racing) converts your kinetic energy into electricity with which to recharge the batteries and reduces wear and tear on the bike’s brakes. The system’s maximum range is up to 150km.
