Smooth-welded seams, an integrated seat clamp and fully internal cable routing underline the purist design. At the heart of the frame sits the compact Pinion C-Line central gearbox with twelve gears in total, keeping the centre of gravity low and central and giving the bike a perfectly balanced feel. The gears can be shifted quickly and reliably even while stationary – an asset that is especially noticeable in city traffic. Combined with the low-maintenance Gates Carbon Drive and the patented Belt Port, through which the belt can be replaced with ease, the elegant belt drive pairs beauty with freedom from maintenance.
The hydraulic Shimano Alfine disc brakes with 160-millimetre rotors bring WILHELM XII C-LINE to a powerful, controlled stop – even when racks, mudguards and panniers load the bike with considerable luggage. For such rides the bike is perfectly prepared: the permissible total weight of 120 kilogrammes leaves generous room for travel baggage, while the 35-millimetre-wide Continental GP Urban tyres glide comfortably over asphalt and light terrain alike. Fine Brooks leather on saddle and grips lends distinction to daily rides as well as weekend outings. Lighting can be added as an option and, thanks to the tidy cable routing, blends seamlessly into the overall appearance. The low bottom bracket combined with the longer head and top tube creates a sporty yet tour-ready riding position that suits dynamic cycling and relaxed stages alike.
The name is composed of several elements, each carrying its own tale. WILHELM is a classic German first name that lends the model a personal, tradition-minded character – fitting for a bicycle line that is individually built to order. XII stands for the twelve gears of the gearbox in Roman numerals, making the gear count visible right in the name. C-LINE in turn names the type of gear system: it is Pinion's compact central-gearbox series, convincing with a small footprint and high performance. Finally, the suffix alu pur reveals the silver finish of the frame, whose unpainted aluminium keeps the material visible in its natural state.
Within the Wilhelm family, WILHELM XII C-LINE occupies the middle, particularly well-balanced gear spread. The sibling models show how versatile the series is: WILHELM IX C-LINE offers nine gears and a clean, consciously reduced stepping, while WILHELM XVIII P-LINE uses the larger P-Line gearbox with eighteen gears for maximum ratio range. WILHELM XII C-LINE draws on twelve gears from the compact C-Line system, sitting exactly between the two and combining everyday usability with sporty flexibility. In the alu pur finish the model also appears unpainted, underscoring the raw, technical character of the aluminium frame.
WILHELM XII C-LINE is the companion for everyone who wants a sporty and dynamic ride in everyday life while valuing an individual, high-end bicycle. It masters the daily commute just as confidently as extended weekend excursions and, thanks to mountable racks, mudguards and optional lighting, even opens the door to multi-day tours and bikepacking. The belt drive combined with the central gearbox requires little care and stays reliably weather-proof. Riders who favour an especially low step-through, in turn, will find a comfortably chosen alternative among the manufacturer's step-through models; WILHELM XII C-LINE itself, with its diamond-frame construction, appeals to riders who appreciate a direct, agile line and a classic frame silhouette.
