How portable is the C9 once it is folded?

The C9 folds to roughly 97 × 46.5 × 76cm, which is very useful for storage and can make vehicle transport much easier than a non-folding city bike.However, it weighs about 30kg. The folding mechanism reduces its size, not its weight, so this is not a bike most people will want to carry up stairs or through a station regularly.

Are the C9 brakes and suspension a meaningful upgrade for longer rides?

Yes. DYU equips the C9 with hydraulic disc brakes and a suspension system, which gives stronger braking feel and better bump control than a basic rigid compact folder on longer or rougher journeys.

Who should choose the C9 instead of the FF500 or C6 Pro?

Choose the C9 if long battery range and a folding 20-inch format are the priorities. Choose the FF500 if you specifically want wide fat tyres and a more rugged-feeling setup, or the C6 Pro for a conventional 26-inch step-through city-bike layout.The C9 is the most storage-friendly of those long-range choices, but at around 30kg it is still a substantial bike to lift.

Is the Bicicletta Elettrica Dyu C9 easy to assemble?

The Bicicletta Elettrica Dyu C9 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 Bicicletta Elettrica Dyu C9 water resistant?

The Bicicletta Elettrica Dyu C9 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

Riepilogo rapido
La bicicletta elettrica a lunga autonomia DYU C9 20″ è una eBike pieghevole di qualità superiore progettata per il pendolarismo urbano, il turismo e l'avventura quotidiana. Combinando un efficiente motore da 250 W con una batteria rimovibile da 48V 15,6Ah ad alta capacità, offre un'autonomia impressionante che può raggiungere i 150 km con pedalata assistita e una guida fluida e reattiva, perfetta per le strade urbane e i percorsi fuoristrada leggeri.

Potenza fluida e reattiva
Il motore brushless da 250 W fornisce un supporto affidabile alla pedalata fino alla velocità massima consentita dalla legge UK/EU di 25 km/h, mentre gli ampi pneumatici da 20″ e il telaio ammortizzato garantiscono una guida confortevole su superfici che vanno dalle strade asfaltate ai sentieri sterrati.

Prestazioni della batteria a lunga autonomia
Con la sua grande batteria da 15,6 Ah, il C9 è costruito per i lunghi viaggi e per il pendolarismo quotidiano senza bisogno di continue ricariche. Le distanze reali possono variare a seconda del livello di assistenza, del terreno e del peso del ciclista, ma l'efficiente sistema di batterie fa entrare questo modello nella categoria delle eBike pieghevoli a lunga autonomia.

Comfort e controllo
I freni a disco idraulici forniscono una potenza di arresto forte e costante in condizioni diverse, mentre la geometria ergonomica del telaio e i componenti delle sospensioni attenuano le asperità per una guida più piacevole. Il display LCD offre una chiara visibilità della velocità, del livello della batteria e della modalità di assistenza.
