What range should I actually plan around on the C3?

DYU's current UK page lists roughly 25km in pure-electric use and about 34km with pedal assistance. Those figures line up with the detailed range table and are a better planning guide than vague 'all day' marketing claims.Use less than the maximum for real journeys, particularly in cold weather, on hills, or if you rely heavily on electric power rather than adding pedal effort.

How much can I put on the C3 rear rack?

DYU lists the C3 rear shelf at up to 25kg. That does not mean you should ignore the bike's overall rider/load limit, and the rack is for luggage only, never a passenger seat.

Is the C3 genuinely portable enough for stairs and public transport?

It is compact, but not featherweight. DYU lists the C3 at about 20kg, so the folding design is most useful for reducing storage size and fitting the bike into a vehicle.For occasional stairs it may be manageable, but if you expect to carry the bike frequently, the weight should be tested against what you are comfortable lifting.

Is the DYU C3 Mini-Elektrofahrrad easy to assemble?

The DYU C3 Mini-Elektrofahrrad arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.

Is the DYU C3 Mini-Elektrofahrrad water resistant?

The DYU C3 Mini-Elektrofahrrad is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.

Description

Kurze Zusammenfassung
Das DYU C3 Mini Electric Bike ist ein kompaktes, faltbares City-E-Bike, das für kurze Pendelstrecken, Fahrten auf der letzten Meile und zur einfachen Aufbewahrung entwickelt wurde. Mit einem 250W Hinterradmotor, einem integrierten 36V 7.5Ah Akku und ultra-kompakten 14" Rädern ist es ideal für Fahrer, die ein einfaches, überall einsetzbares Elektrofahrrad suchen, das leicht zu heben, zu parken und zu verstauen ist. Trotz seiner geringen Größe bietet das C3 eine für die Straße zugelassene Leistung mit einer Höchstgeschwindigkeit von bis zu 25 km/h und eine praktische Reichweite für tägliche Fahrten in der Stadt.

Sanfte Leistungsentfaltung
Das DYU C3 verfügt über einen 250-W-Hinterradnabenmotor (500 Watt Spitzenleistung), der für eine sanfte Beschleunigung auf bis zu 25 km/h ausgelegt ist und damit den britischen und EU-Vorschriften für E-Bikes entspricht. Zwei Fahrmodi ermöglichen Ihnen die Wahl zwischen reinem Elektroantrieb für müheloses Cruisen und Tretunterstützung, um die Reichweite zu erhöhen und ein wenig Bewegung in das Rad zu bringen. Die gleichmäßige Leistungsabgabe des Motors ist ideal für den Stop-and-Go-Verkehr in der Stadt und für leichte Steigungen, denn sie gibt Ihnen genügend Schub, ohne dass Sie sich ruckartig oder übermotorisiert fühlen.

Komfort und Kontrolle
Obwohl es sich um ein Mini-E-Bike handelt, ist das C3 auf alltäglichen Komfort ausgelegt. Die 14×2,125-Zoll-City-Reifen bieten eine breitere Aufstandsfläche als herkömmliche Mini-Bike-Reifen, absorbieren Unebenheiten und verbessern die Bodenhaftung auf Asphalt, Pflaster und Radwegen. Die gefederte Sattelstütze und der ergonomisch geformte Sattel sorgen dafür, dass auch rauerer Untergrund nicht zum Problem wird, und das niedrig angesetzte Rahmendesign erleichtert das Auf- und Absteigen, selbst im städtischen Stop-and-Go-Verkehr. Der kompakte Radstand und die kleinen Räder machen das Rad sehr wendig in engen Räumen und im Stadtverkehr.

Intelligentes Batteriesystem
Der rahmenintegrierte 36V 7,5Ah Lithium-Ionen-Akku ist für kurze bis mittlere Fahrten in der Stadt ausgelegt. Unter idealen Bedingungen können Sie mit ca. 20-25 km im reinen Elektromodus und ca. 30-40 km mit Tretunterstützung rechnen, je nach Gewicht des Fahrers, Gelände und Temperatur. Der Akku ist in etwa 3-4 Stunden von leer auf voll aufgeladen, so dass er tagsüber oder über Nacht problemlos nachgeladen werden kann. Das integrierte Design lässt das Fahrrad sauber und kompakt aussehen und schützt den Akku vor Spritzwasser und Stößen.
