A bright cream white makes frame and fork appear as if cast in one piece and gives this bike a puristic elegance behind which the technology recedes while remaining present. It is made from heat-treated AL6061-T6 in the triple-butted Aero-Shape tube set – robust at the welds, slim in the middle, stiff in between. The forged bottom bracket shell and forged dropouts with slider tensioning system and belt port absorb the loads; the integrated motor plug disappears neatly into the tube, the integrated seat clamp keeps the line calm, and smoothed welds plus internal cable routing keep the surface flawless. A hydroformed aluminium fork with tapered steerer, internal cable routing, post mount mount and 15 mm through-axle complete the picture.

Nine mechanical gears sit in the Pinion C-Line gear unit, which is closed and housed in the bottom bracket. These nine steps spread the ratios finely across the entire range, so every gradient has a suitable gear ready and the pedalling stays smooth. Shifting also works while standing, which changes the gear at the traffic light within seconds. The low position inside the bottom bracket lowers the centre of gravity, the closed construction stays reliable in rain and dirt, and the XR specification is developed for higher loads and sportier riding.

Everything is linked by the Gates Carbon Drive CDX belt: 115 teeth on the belt, 39 teeth at the front and 28 teeth at the rear. Belt port and slider tensioning system keep the tension permanently adjustable. That means around three to four times as many kilometres as with a chain at the same efficiency, plus maintenance effort of a few hand movements per year – and clean clothing on the way.

The MAHLE X20 system drives the bike: the hub drive motor in the rear wheel delivers 250 watts and 55 Nm of torque with support up to 25 km/h and is mounted via a 12 mm through-axle. The inTube battery with around 250 Wh sits fully integrated in the down tube, and the head unit is located in the top tube – Bluetooth and ANT+ make control possible directly on the frame. Three support levels adapt to the terrain. Because the motor is feather-light and engages at the rear wheel only, the bike also rides sovereignly without assistance, the drivetrain stays free and the belt is protected.

Compact StVZO lighting technology is fitted as standard here: the LightSkin City handlebar houses the headlight, the LightSkin seatpost the taillight. Both lights draw their power from the battery and are therefore ready to go at any time, so while pedalling the e-bike forms a complete lighting system that works just as reliably in the city as at dusk.

Comfort and control come from Curana Dlite mudguards against rain and dirt, the Satori Stealth stem made of aluminium, Schindelhauer ergo leather grips and the Brooks B17 S Lady saddle on a chromed rail, which sits softly and upright. Shimano Alfine S7000 hydraulic brakes with 160 mm discs brake strongly and with precise modulation, and Schindelhauer Urban Pedals made from CNC-machined aluminium belong to the package. Schindelhauer StraightPull hubs with Kinlin TL23R rims and Sapim Race spokes give the wheel high stiffness, while Continental GP Urban Classic tyres in 35-622 ensure calm running on asphalt and secure grip on cobbles. In size M the bike weighs 15.9 kg, and 130 kg total weight are approved.

Outings with luggage are well prepared: the rear rack attachment takes luggage, and bottle, lock and kickstand find their place. With the wide city tyres, the belt drive and the integrated lighting, the result is a package that keeps running reliably and needs little care even after a full working day.

Antonia IX X20: how the model name comes about

The urban model lines of this brand carry first names instead of technical type codes, so that every bike gets its own personality. “Antonia” is the name of this bike and forms a deliberately chosen name pair with “Arthur” in female and male form. “IX” is a Roman numeral and at the same time the gear count: IX stands for nine gears of the Pinion C-Line, while the VI variant brings six steps. “X20” names the fitted motor system, the MAHLE X20 hub drive with 55 Nm of torque, while the models coded X35 deliver 40 Nm. Cream white is the paint of this bike, and the second colour of the series is called sage green.

Differences between the models of the series

Within the series two degrees of freedom can be combined: the number of gears and the motor generation. The VI X20 shares the 55 Nm with this model but works with six larger steps; the IX variants offer nine finely graduated gears and can be ordered with either the X20 motor or the X35 motor with 40 Nm. Compared with the X35 version, the X20 equipment adds three adjustable support levels via the head unit in the top tube, a 12 mm through-axle, Shimano Alfine S7000 hydraulic brakes and the StraightPull wheelset with Kinlin TL23R rims; the Curana Dlite mudguards complement the CLite equipment of the X35 models. At 15.9 kg in size M the weight remains on the level of the other urban e-bikes of this family.

Colourwise you can choose between cream white and sage green, and the frame sizes XS at 48 cm, S at 52 cm and M at 56 cm frame length suit body heights of about 155 to 165 cm, 165 to 175 cm and 175 to 185 cm. Beyond the drive variants, the programme includes other lines: the gravel diamond frame relies on sportier components for faster tours, the Bosch-driven e-bikes deliver even more torque for steep mountain routes, the Nexus models target the plain city machine and the singlespeeds the reduced solution for everyone who deliberately prefers a simple drivetrain.

Purpose: everyday, gradients and tours with luggage

This Antonia is built as an avant-gardist e-bike for everyone who gets on the bike in everyday life and wants to experience automotive technology while doing so. 55 Nm of torque help on steep sections and when starting off with luggage, the nine Pinion steps ensure calm rolling on the flat, and the trapez frame with sloping top tube lowers the standover height, makes mounting and dismounting in everyday clothing easier and leads to a more upright, more relaxed riding position – a noticeable advantage in dense city traffic with frequent stops.

The male counterpart exists: Arthur carries the same technology in diamond form, with a straight top tube and classic, sporty elegance, and is available in XS at 50 cm, S at 53 cm, M at 57 cm and L at 59 cm. What counts is therefore the preferred riding position, not gender – similarly as with Emilia alongside Emil, Greta alongside Gustav or Lotte alongside Ludwig. Compared with the X35, the X20 variant is the choice for everyone who wants maximum torque reserves and the finest gear count; compared with the Bosch-driven bikes the one who prefers an especially light, quiet system with hub motor; and compared with the singlespeed and Nexus models the one who deliberately wants to experience the drivetrain in multiple steps.
