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 Mini rower elektryczny DYU C3 easy to assemble?

The Mini rower elektryczny DYU C3 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 Mini rower elektryczny DYU C3 water resistant?

The Mini rower elektryczny DYU C3 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

Krótkie podsumowanie
Mini rower elektryczny DYU C3 to kompaktowy, składany miejski rower elektryczny zaprojektowany z myślą o krótkich dojazdach do pracy, pokonywaniu ostatnich kilometrów i łatwym przechowywaniu. Dzięki tylnemu silnikowi o mocy 250 W, zintegrowanemu akumulatorowi 36 V 7,5 Ah i ultrakompaktowym 14-calowym kołom jest idealny dla rowerzystów, którzy chcą prostego roweru elektrycznego, który można łatwo podnieść, zaparkować i przechowywać. Pomimo niewielkich rozmiarów, C3 zapewnia osiągi zgodne z przepisami drogowymi z prędkością maksymalną do 25 km/h i praktycznym rzeczywistym zasięgiem podczas codziennych podróży po mieście.

Płynne dostarczanie mocy
DYU C3 wykorzystuje silnik w tylnej piaście o mocy 250 W (szczytowa 500) dostrojony do płynnego przyspieszania do 25 km/h, dzięki czemu jest zgodny z przepisami dotyczącymi rowerów elektrycznych w Wielkiej Brytanii / UE. Dwa tryby jazdy pozwalają wybrać między napędem elektrycznym do bezwysiłkowej jazdy lub wspomaganiem pedałowania, aby zwiększyć zasięg i dodać trochę ćwiczeń. Stałe dostarczanie mocy przez silnik jest idealne do zatrzymywania się w ruchu miejskim i łagodnych wzniesień, zapewniając wystarczające doładowanie bez uczucia szarpania lub nadmiaru mocy.

Komfort i kontrola
Chociaż jest to mini e-rower, C3 został zbudowany z myślą o codziennym komforcie. Opony miejskie 14 × 2,125 cala zapewniają szerszą powierzchnię styku niż standardowe opony do mini-rowerów, pomagając pochłaniać nierówności i poprawiając przyczepność na asfalcie, chodniku i ścieżkach rowerowych. Sprężynowy amortyzowany sztyca i ergonomiczne siodełko pomagają zniwelować nierówności nawierzchni, a niskostopniowa konstrukcja ramy ułatwia montaż i demontaż, nawet podczas zatrzymywania się w mieście. Kompaktowy rozstaw osi i małe koła sprawiają, że rower jest bardzo zwrotny w ciasnych przestrzeniach i ruchu miejskim.

Inteligentny system akumulatorów
Zintegrowany z ramą akumulator litowo-jonowy 36 V 7,5 Ah jest przeznaczony do krótkich i średnich podróży po mieście. W idealnych warunkach można oczekiwać około 20-25 km w trybie wyłącznie elektrycznym i około 30-40 km ze wspomaganiem pedałowania, w zależności od wagi rowerzysty, terenu i temperatury. Akumulator ładuje się od pustego do pełnego w około 3-4 godziny, więc łatwo go uzupełnić w ciągu dnia lub w nocy. Zintegrowana konstrukcja sprawia, że rower wygląda schludnie i kompaktowo, jednocześnie chroniąc akumulator przed opryskaniem i uderzeniami.
