The ARTHUR IX X35 is built around a triple-butted, aero-shaped AL6061-T6 aluminium tubeset. A forged bottom bracket shell, an integrated seat clamp and forged dropouts with a sliding tensioning system plus the patented belt port define how this frame works. Internal cable routing and smoothed welds keep the exterior free of visible lines, while the hydroformed, tapered aluminium fork with its 15 mm through-axle and post mount brake interface holds the bike true under hard city riding. In frame sizes S (53 cm), M (57 cm) and L (61 cm) it rolls on eyeleted Alexrims CXD26 rims, Sapim Race spokes and Continental GP Urban Classic tyres in 35-622.

Shifting happens through a Pinion C-Line gear unit with 9 speeds (XR), completed by Pinion inner bearing and Pinion crankset. Paired with the Gates Carbon Drive CDX (39 teeth in front, 34 or 28 at the rear, belt lengths 118T/115T), this gear hub changes precisely and quietly even while standing still: gear jumps flow smoothly, and the carbon toothed belt neither needs lubricant nor leaves marks on your trousers. The barely visible Mahle ebikemotion Hub Drive M1 in the rear wheel supplies 250 W and 40 Nm up to 25 km/h, with the roughly 250 Wh Intube battery tucked into the down tube, controlled through the iWoc ONE with Bluetooth and ANT+ as well as via app. Two energy-saving companions complete the concept: Curana CLite mudguards as standard equipment and Shimano Alfine hydraulic disc brakes with 160 mm rotors.

What shapes this bike in everyday use is the LightSKIN lighting system. The VIENNA handlebar integrates the StVZO-compliant front light, the LightSKIN seat post integrates the rear light, both recessed flat into cockpit and post and powered directly from the e-bike battery. The visible silhouette therefore stays as clean as on a non-electrified bike from the same workshop. Longer routes are catered for with a rear rack mount at the dropouts, bottle cage and lock fittings on the seat tube and a prepared kickstand mounting point. With an approved system weight of 130 kg and a weight of around 15.7 kg, this bike carries luggage and shopping with composure, while a Brooks B17 saddle, Schindelhauer ergo leather grips and CNC-machined urban pedals round out the comfort on longer stages.

How the name ARTHUR IX X35 came about

The model name is built from three parts that together describe the configuration. “ARTHUR” is the designation of the series – internally labelled the avant-gardist, that something in between a classic city bike and a sporty build that only appears electrified through its drive. “IX” is a Roman numeral standing for the nine gears of the installed Pinion C-Line; the sibling version with six gears carries the corresponding tag “VI”. “X35” names the drive generation from manufacturer Mahle: the X35 series with a 250 W hub motor and an Intube battery of around 250 Wh. The colour variants Midnight Blue and Cream White are listed separately in dealer naming and are not part of the technical model designation.

What sets the IX X35 apart within the range

Three axes differentiate the models of the range: the number of gears, the generation of the electric drive and the tyre setup. Compared with the singlespeed version, which stays at a single gear and with the lightweight Shimano Alfine crankset keeps the weight near 13.4 kg, the IX X35 shifts nine gears and therefore offers the full range for urban traffic and steep climbs. The VI version shares the same frame, the same Pinion crankset and the same 35 mm tyres but reduces the gear unit to six speeds – ideal for flat rounds that prefer fewer gear changes and lower weight. The IX X20 likewise carries nine gears but relies on the newer X20 generation of the Mahle system: more torque, a human machine interface with freely selectable assistance levels and a control unit in the top tube. A separate character comes with the ARTHUR Cruiser, whose wide47-584 tyres, strongly swept-back handlebar, Pelago front basket and weight of 15.9 kg put relaxed cruising rather than sporty riding centre stage. All variants share frame, Gates drive, Pinion technology and lighting integration, so switching between them remains a genuine decision about gears, torque and riding style.

What this bike is built for

The ARTHUR IX X35 is designed for daily urban mobility: short commutes to work, shopping trips and rides through city traffic, where an agile, sporty manner combined with electric support up to 25 km/h sets the tone. Within this manufacturer's portfolio the boundaries become clear. The Emil and Emilia lines are the comfort-focused entry option with an upright seating position and the same Pinion principle, while Arthur appears sportier and more direct. Classic road or singlespeed offerings such as the Wilhelm family target training and pure muscle power, and with an electrified urban bike everyday comfort moves to the foreground instead.

A female counterpart exists as well: the ANTONIA shares frame geometry, Pinion variants and Mahle drives with this bike, but is conceived as a step-through with a lowered top tube and an additional XS frame. Anyone who prefers an upright riding position therefore finds the same technical approach in two frame silhouettes – a diamond frame for a sporty-classic feel, a lowered entry for relaxed arrival.
