Where the name Arthur comes from

Schindelhauer names its entire model range after traditional European first names – a stylistic choice that lends the urban bikes a personal touch. "Arthur" is an old German and English given name derived from the Celtic root "artos" (bear), meaning "bear-strong" or "bear-like". In the Schindelhauer universe, Arthur stands for the diamond-frame variant of the minimalist e-bike series, while Antonia is its technically identical step-through sibling. The choice of a masculine name for the diamond frame and a feminine one for the low-entry version follows a pattern common among many European manufacturers.

What the model code breaks down to

The suffix "IX" is the Roman numeral for 9 and indicates that the ARTHUR is equipped with the Pinion C-Line gearbox with nine speeds. This compact gear unit, developed by former Porsche engineers, sits directly in the bottom bracket and delivers a gear range of 636 percent. The abbreviation "X20" refers to the Mahle X20 system, consisting of a quiet rear hub motor (250 W, 55 Nm) and a 250 Wh in-tube battery integrated into the down tube. Combined, the model code therefore reads: Arthur (frame type), IX (nine gears), X20 (Mahle drive).

Who the ARTHUR IX X20 is designed for

The ARTHUR IX X20 targets urban riders who want a virtually invisible e-bike with high design standards and minimal maintenance. The diamond frame appeals to those who prefer a classic, sporty look. Within the Arthur range, the IX X20 occupies the upper middle position: below it sits the ARTHUR X20 SSP (single-speed, no gearbox) for riders in flat terrain, while the VI X20 offers a narrower gear range with six speeds. Above it are positioned the ARTHUR IX ULTIMATE with finer components and the models with the Mahle X35 drive. The ARTHUR IX X20, with its combination of a broad nine-speed gearbox range and the lightweight Mahle X20 motor, is especially suited to commuters facing varying gradients, longer distances and high aesthetic expectations – the battery stays hidden, the motor remains discreet, and only a subtle button on the top tube hints at the electrification.
