THE FOLLOWING CALCULATION WILL HELP YOU FIND THE RIGHT BIKE FRAME SIZE AND SADDLE HEIGHT:

Road/Gravel Inside leg x 0,66 = Frame size in cm
MTB Size S: 155 – 172 cm body height
Size M: 173 – 182 cm body height
Size L: 183 – 192 cm body height
Size XL: >192 cm body height
Fitness
or
Inside leg x 0,61 = Frame size in cm
Inside leg x 0,24 = Frame size in inches
Hybrid/Touring
or
Inside leg x 0,61 = Frame size in cm
Inside leg x 0,24 = Frame size in inches
Inside leg x 0,885 = Saddle height on all bikes

If you are exactly between two sizes, you'll have the choice: Choose the smaller frame if you prefer a "racing position" and the bigger frame if you prefer a more comfortable "touring position".

See our video step-by-step instructions on how to determine your frame size. We'll explain you how to easily measure shoulder width, inside leg length and arm length yourself.

Love this bike! The geometry is perfect, wheels and frame are nice and stiff. The gearing works great for this price point and the brakes have nice modulation and stopping power.

Das Fahrrad ist von der Größe perfekt und es lässt sich gut schalten.
Auf Asphalt ist es ebenfalls top. Sobald nur minimal Schotter dazu kommt, leider der Komfort sehr stark und es macht keinen Spaß zu fahren. Dies sollte beim Kauf berücksichtigt werden.
Versand und Kundenservice sind sehr gut und schnell.
Der Sattel ist dafür sehr unbequem, seitlich abgerundet und nach kürzester Zeit tut einem den Hintern weh. Auch ist er nicht ergonomisch geformt.
Die Schaltung ist leider nicht gut voreingestellt gewesen. Hierzu musste ich in ein Fahrradgeschäft vor Ort und es nachstellen lassen. Rose hat die Rechnung dafür übernommen.
Aufgrund des Sattels gibt es jedoch 1 Stern Abzug. Hier spart der Hersteller ungerechtfertigt.

An sich mega gut zu fahren, kommt sehr gut verpackt an, ist einfach zusammen zu bauen! 4/5 Sternen... Der einzige Minuspunkt wäre ein wirklich zu harter Sattel... Aber ist meine persönliche Meinung ✌🏽

Ist mein erstes höherpreisiges Fahrrad gewesen und bin deshalb von der Verarbeitung und den Eigenschaften ziemlich beeindruckt. Optisch und technisch gab es bis jetzt keinen Grund zur Beanstandung, das Fahrrad bekommt man schnell in den Griff und es macht richtig Spaß.

    Category 2

    This category applies to bicycles and e-bikes* that meet the conditions of category 1 and are ridden on normal roads as well as in category 2 on unpaved roads and gravel paths with moderate inclines and descents. The tyres are in constant contact with the ground at average speed and they are only occasionally ridden over steps and drops of less than 15 cm. These conditions can lead to contact with uneven terrain and the tyre repeatedly losing contact with the ground. The intended use is, for example, recreational riding. You don’t require any special riding skills.

    Average speed 15 to 25 km/h

    Height of steps and drops: < 15 cm

    *E-Bikes = 250W 25km/h
