Product Description

Please note: the majority of our electronic products that come with plugs are fitted with 2-pronged EU plugs as standard. The operating voltage remains the same, however you may require an additional, simple EU to UK adapter to use them.

Please note: all of our bike models come with an EU standard brake setup. This will need to be reversed to comply with UK cycling standards.

With its classic diamond frame, the Ortler Oslo urban e-bike gives you the extra power you need for everyday cycling and weekend excursions. The new AEG ComfortDrive middle-mounted motor with assisted start is cleverly integrated into the aluminium frame and assists the rider when pedalling at speeds of up to 25 km/h. The powerful AEG battery is hidden discreetly in the down tube, giving the Oslo a sporty, modern look.

The comfortable, upright seat position offers a superior view over city traffic and with the adjustable stem every rider can find their preferred position. The patented seatpost and rigid front fork give the rider sporty feedback on urban day rides. An 8-speed Shimano Acera derailleur ideally complements the electric motor and the Shimano hydraulic disc brakes offer enough braking power for every situation. Lighting, chainring guard, stand and fixed mudguards complete the overall package. Although the bike forgoes a classic rear rack, two panniers can easily be attached at the rear wheel. 

Special Features

10 years warranty


10 Year Guarantee

As a thank you to our customers, Bikester voluntarily grants an additional 10-year warranty for all VOTEC's owners, Serious, Vermont, Fixie and Ortler bikes from the date of purchase (except the VOTEC VRC which comes with a 6-year warranty on frame and fork). This warranty covers all frames from the year 2013 onwards and guarantees a replacement or repair. Follow-up costs such as assembly and transport are not included. The warranty excludes damage caused by improper use, such as: jumps, falls, overload or neglect. The guarantee expires in the case of unauthorised changes to the frame as well as the installation and conversion of additional components. In addition, a two-year warranty applies to every parts and surface.


How many miles will my battery last?  
Can I get 50 miles from one battery charge or even 120? For those interested in buying an e-bike, this is a very important question. Manufacturers try to be as realistic as they can about possible ranges your e-bike may manage on one complete battery charge. In practice, however, the maximum range depends on many different factors.  As well as the type of motor you have, factors include the energy content (400 or 500 Wh), handling and age of the battery. However, the rider's weight, sitting position, riding style (starting frequency, cadence) and selected support levels (Eco, Tour, Sport, Turbo) all greatly influence the range. Last but not least, the track profile (uphill or flat), the ground (road or terrain), wind (headwind, tailwind) and even tyre profile effect distances possible. This makes it extremely difficult to provide precise and reliable information.

Price / performance ok, small flaws
Preis/Leistung ok, kleine Schönheitsfehler
Translated from German To the original

Positive: Looks really good, solid processed. Range is ok (after 30km with 300 meters altitude slope remain about 50% battery). Engine is very powerful, makes shifting almost superfluous Negative: AEG App can not be used as promised in the product description, because no Bluetooth function. Cable to sensor on the rear wheel laid with cable ties instead of in the frame. No castle. Stem not adjustable. Engine support not very harmonious (full thrust or off). Stability of luggage carrier doubtful. Conclusion: Who wants a really perfect eBike must pay at least 1000 francs more. But for just under 2,000 francs sure a good buy.

Positiv: Sieht wirklich sehr gut aus, solide verarbeitet. Reichweite ist ok (nach 30km mit 300 Höhenmetern Steigung verbleiben ca. 50% Batterie). Motor ist sehr kräftig, macht Schalten fast überflüssig Negativ: AEG App lässt sich nicht, wie in der Produktbeschreibung versprochen, nutzen, da keine Bluetooth Funktion. Kabel zu Sensor am Hinterrad mit Kabelbindern verlegt anstatt im Rahmen geführt. Kein Schloss. Vorbau nicht verstellbar. Motorunterstützung nicht sehr harmonisch (Voll Schub oder aus). Stabilität des Gepäcktaschenträgers zweifelhaft. Fazit: Wer ein richtig perfektes eBike möchte muss mindestens 1000 Franken mehr bezahlen. Aber für knapp 2000 Franken sicher ein guter Kauf.
