How small does the D3F actually get when it is folded?

The D3F is better described as compact or semi-folding than suitcase-small. DYU lists a folded size of about 117 × 20 × 72cm, so the bike becomes much narrower but keeps most of its original length.That works well for a car boot, hallway, office or camper, but it is not a tiny package you would want to carry around a station for long periods.

Does the D3F have app control, or is it a simple stand-alone bike?

DYU's current comparison information lists no phone app for the D3F. It is intentionally simple, although the current UK model does include a cruise function for steady-speed riding.

What range should I realistically plan around on the D3F?

DYU's current UK specification lists up to around 50km in pedal-assist use and around 40km using throttle mode. Those are maximum test figures, not a guaranteed everyday distance.Rider weight, cold weather, hills, stop-start riding and higher assistance all reduce range, so leave a useful reserve rather than planning a journey around the final kilometre of the claim.

Is the Dyu D3F 250W 14" Vélo Électrique Pliant easy to assemble?

The Dyu D3F 250W 14" Vélo Électrique Pliant 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 D3F 250W 14" Vélo Électrique Pliant water resistant?

The Dyu D3F 250W 14" Vélo Électrique Pliant 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

Traversez la ville en tyrolienne

Le moteur silencieux de 250 W du D3F offre une accélération fluide dès que vous actionnez la poignée d'accélérateur ou sélectionnez l'un des trois niveaux d'assistance au pédalage. Idéal pour les courses rapides ou pour se faufiler dans la circulation, il donne l'impression de voler.

Puissance de poche

Malgré ses petites roues de 14 pouces et son cadre minimaliste, le D3F dissimule une batterie de 36 V et 7,8 Ah qui se retire facilement pour se recharger en moins de 4 heures. Une fois la batterie chargée, vous parcourrez jusqu'à 40 km en mode tout électrique, et jusqu'à 60 km en utilisant le pédalage.

Le confort dans un petit format

Des pneus robustes et increvables ainsi qu'une selle à ressort absorbent les chocs que vous ne ressentiriez jamais sur un vélo aussi petit. Vos articulations — et votre café du matin — vous remercieront lorsque vous franchirez fissures, pavés ou dos d'âne sans la moindre secousse.

Se plie en un éclair

Un système de fixation rapide sur la potence et la charnière du cadre permet de replier le D3F de manière à ce qu'il prenne suffisamment de place pour les porte-bagages de bus, les sols de train et les recoins de bureau. Avec seulement 18 kg, il est assez léger pour être transporté dans les escaliers ou rangé sous un bureau.

Une sécurité sur laquelle vous pouvez compter

Les LED avant et arrière assurent votre visibilité au crépuscule, tandis que les freins à disque mécaniques garantissent un freinage efficace par tous les temps. Des éléments réfléchissants sur le cadre vous offrent une visibilité accrue en conditions de faible luminosité.
