A crankset is a central component on a bicycle that consists of two crank arms to which the pedals are attached. The crankset is held in place by the bottom bracket shell in the middle of the bicycle frame and allows the rider to push the pedals and set the bicycle in motion.
There are different types of cranksets that can vary in terms of material, size and shape. Some cranksets are made of aluminum or carbon to save weight and maximize performance. Others are made of steel or alloy steel to make them more resistant to wear and damage.
High-quality cranksets can extend the life of the bottom bracket because they help reduce weight.
Another important feature of the crankset is the ratio of chainring to pinion teeth, which is called the gear ratio. A higher gear ratio allows for higher speeds but also requires a higher cadence. A lower gear ratio allows for easier pedaling but is slower.
Modern cranksets typically offer a variety of gear ratios that can be changed by changing the chainrings and pinions on the rear hub. These combinations allow cyclists to adapt their gearing to different road and terrain conditions.
The crankset is also an important component in e-bikes , which is crucial for the bike's drive. E-bikes have an electric motor that supports the rider when pedaling, but the drive power is also transferred to the rear wheel via the crankset.
However, an important difference with e-bikes is that the electric motor also has its own driving force and can therefore relieve the rider. The support provided by the electric motor can be controlled manually or automatically as required to reduce pedalling effort or to support the rider on inclines or in headwinds.
Wenn in München die Wiesn-Zeit beginnt, heißt es wieder „O’zapft is!“. Millionen Besucher strömen jedes Jahr zum Oktoberfest, um bayerische Tradition, Tracht, Bier und Gaudi zu genießen. Doch während Festzeltstimmung und Fahrgeschäfte locken, stellt sich schnell die Frage: Wie kommt man am besten hin und wieder sicher nach Hause? Eine clevere Antwort darauf ist: mit dem Fahrrad!
Radfahren ist weit mehr als nur Sport oder Fortbewegung – es ist auch ein soziales Erlebnis. Immer mehr Radbegeisterte schließen sich sogenannten Social Rides an. Dabei geht es nicht um Bestzeiten oder knallhartes Training, sondern um Gemeinschaft, Spaß und geteilte Leidenschaft fürs Rad.
Sarcopenia – this medical term refers to a very real problem: the age-related loss of muscle mass and strength. Starting around the age of 50, the body loses up to 1–2% of its muscle mass annually. The consequences: weakness, unsteadiness when walking, and the risk of falls. But this doesn't have to be the case. Exercise is the best remedy for muscle atrophy – and this is precisely where the e-bike comes in. It enables regular, joint-friendly muscle training even in old age – without overexertion.
