The Kettler Alu-Rad Traveller 1.0 21G 28 Zoll Trekking City Bike brings a classic European trekking setup into focus, combining a 28 inch wheel size with a 3x7 gear drivetrain aimed at everyday commuting and weekend touring. This model uses an aluminum frame and is configured as an adult bicycle with equipment for road and paved-surface riding, including a hub-dynamo lighting system and luggage rack integration.
Frame, Wheels and Riding Geometry
The Traveller 1.0 21G is specified as a 28 Zoll trekking and city bike with an aluminum frame designed for adult riders.The product listing describes it as an Erwachsenenfahrrad in the Trekking & City group with a 28 Zoll wheel size. The frame height on one documented configuration is 55 cm, which positions the bike for medium to taller adult riders who prefer an upright posture.The same source lists a Rahmenhöhe of 55 cm for this dark blue matt version.
The wheel and tire combination follows a typical trekking specification. The bike runs on 28 inch rims with tires in size 47-622, a format suited to road and asphalt with enough volume for moderate comfort.The product data list Radgröße 28 Zoll and Reifengröße (ETRTO) 47-622. Aluminum rims are used front and rear, contributing to the declared bike weight and durability for everyday use.The same specification table notes aluminum for both front and rear rims.
Drivetrain, Suspension and Braking
Central to the Traveller 1.0 21G is its 21 gear drivetrain implemented as a 3x7 system. This layout offers three chainrings paired with a seven-speed cassette, providing a broad spread of ratios for climbs and flat sections.The manufacturer description highlights 3 x 7 Gänge as delivering sufficient bandwidth for typical trekking use. The retail specification confirms the bike as using a Kettenschaltung with 21 gears, aligning with the trekking and city role.The detailed retailer table lists Anzahl Gänge 21 Gang and identifies the drivetrain as Kettenschaltung.
The front end uses an SR Suntour CR-8V-P suspension fork with a specified travel of 40 mm, which is enough to damp small bumps on urban streets without turning the bike into a full off-road model.The specification notes Gabel SR SUNTOUR CR-8V-P and Federweg (vorne) 40 mm. Braking is handled by V-brakes front and rear, with TEKTRO hardware and Shimano ST-EF500 brake levers integrated into the cockpit.The retailer spec lists Bremstyp V-Brake, rear brake TEKTRO 837AL-EN and brake levers SHIMANO ST-EF500.
Lighting, Luggage and Weight Limits
For everyday usability, the Traveller 1.0 21G is equipped with a hub-dynamo lighting system. The front light unit is specified as a FUXON F-16 rated at 20 lux, giving a basic, road-legal beam for city riding.The data table identifies the frontleuchte as FUXON F-16, 20 lux and the lighting as powered by a Nabendynamo. The official manufacturer description for the current generation of the model also notes a light system with hub dynamo and highlights this as part of its typical trekking equipment set.The manufacturer overview mentions a Lichtanlage mit Nabendynamo and typical trekking components including lighting.
Luggage handling is based on a dedicated rear rack system. The bike uses a StandWell rack configured with the MonkeyLoad system, allowing compatible bags and accessories to clip into place with a single motion.The manufacturer description highlights the MonkeyLoad Systemgepäckträger where a single Klick fixes attached bags. The combination of rack and overall frame design supports a permissible total weight, or zulässiges Gesamtgewicht, of 130 kg, covering the bike, rider and luggage.The retailer specification notes a zulässiges Gesamtgewicht of 130 kg and a bike weight of 16.5 kg.
With a listed bike weight of about 16.5 kg, the Traveller 1.0 21G sits in the usual range for fully equipped trekking and city bikes that include suspension, lighting and racks.The specification table explicitly lists Gewicht 16,5 kg. The manufacturer narrative reinforces the intended everyday role by emphasizing an upright seating position and a design meant for both touring and daily trips.The product description notes an angenehm aufrechte Sitzhaltung and highlights suitability for Touren and Alltag.
Kettler Traveller 1.0 21G Trekking Details
Technical data, frame forms and equipment variants for the Traveller 1.0 21G are documented on the official Kettler Alu-Rad site.
Manufacturer, Brand and Market Context
The Traveller 1.0 21G is produced by KETTLER Alu-Rad GmbH, headquartered on Longericher Straße 2 in 50739 Köln, Germany.The manufacturer listing on the product page names KETTLER Alu-Rad GmbH at this address as Hersteller and Inverkehrbringer. Kettler Alu-Rad functions as the consumer-facing bicycle brand within the broader Kettler environment, and documentation for the bike also appears in the brand's operating instructions for model year 2019 city and trekking bicycles.The operating instructions list Traveller 1 (21-speed) as a city and trekking bicycle under the KETTLER Alu-Rad line.
While Kettler Alu-Rad is primarily a European brand, the Traveller 1.0 21G represents the kind of fully equipped trekking bicycle that can be relevant in markets where similar bikes are imported through local dealers. However, current detailed pricing information is documented in euros and presented through European and German retail channels.A German bicycle retailer lists the Traveller 1.0 21G at 799,00 Euro including VAT. In practical terms, this places the bike in the upper midrange of trekking city models when compared against typical European price bands for fully equipped aluminum trekking bikes with suspension, hub lighting and branded components.
Comparison Within Trekking City Bikes
Within its segment, the Traveller 1.0 21G can be compared to other Kettler trekking city models that offer fewer gears or different equipment mixes. A general description of Kettler's trekking and city category runs from comfortable low-entry bikes with 7-speed hub gears to more touring-oriented designs with suspension forks, higher gear counts and more advanced braking systems.The Trekking & City category overview describes offerings from 7-Gang-Nabenschaltung low-entry bikes up to sportier touring models with Federgabel, disc brakes and 30 gears. Against this spectrum, the Traveller 1.0 21G positions itself with 21 gears, V-brakes and a 40 mm travel fork, providing more gearing flexibility than 7-speed hub models but staying below the more heavily specified 30-gear disc-brake touring bikes.
From a weight and capacity perspective, the Traveller 1.0 21G at 16.5 kg with a 130 kg permissible total weight lines up with other fully equipped trekking bikes that often fall in a similar mass range and total load rating. Many lower-spec city bikes that omit suspension and sometimes use simpler racks can weigh slightly less, but they frequently offer fewer gears and less sophisticated load-handling systems. In contrast, higher-tier touring bikes with additional gear range, heavier-duty racks or disc brakes may push weight slightly above this figure while maintaining or modestly increasing total permissible load. The Traveller 1.0 21G thus occupies a balanced middle ground with a focus on practical everyday use and moderate touring capability.
Use Case and Editorial Verdict
For adult riders seeking a trekking city bicycle with integrated lighting, a fitted rear rack and a meaningful 21-gear range, the Kettler Alu-Rad Traveller 1.0 21G offers a coherent package. Its 28 inch wheel and 47-622 tire combination is aligned with paved surfaces and light touring, while the SR Suntour CR-8V-P fork and V-brakes are tuned for comfort and straightforward maintenance. With a 130 kg permissible total weight covering rider and luggage, the bike is suitable for riders who want to combine commuting, shopping trips and recreational rides without worrying about exceeding the system limit.
The editorial verdict situates the Traveller 1.0 21G as a solid choice for mixed-use cycling where practicality takes precedence over extreme performance. Riders who prioritize a wide but not excessive gear spread, dependable braking, basic but road-ready lighting and a rack system capable of handling panniers will find its specification coherent. Those who demand the very latest braking technology or more than 21 gears might look toward disc-brake, 27- or 30-gear touring bikes in the same Kettler category, but for many everyday and weekend scenarios the Traveller 1.0 21G delivers a balanced set of features.
