Product information
The benefits at a glance
- 48V / 18Ah / 864Wh
- Autonomia fino a 75 km
- Si ricarica dentro e fuori dalla bici
Adatto per: QMWheel S20 Pro
Una batteria singola per la QMWheel S20 Pro. Questa batteria da 48 volt ha una capacità di 18Ah, per un totale di 864Wh. Con essa la S20 Pro percorre in media circa 60 km e fino a 75 km con assistenza bassa, a seconda del livello di assistenza, del peso e del terreno.
La batteria può essere ricaricata in due modi:
Sulla bici: lascia la batteria nel telaio e collega il caricabatterie alla bici. Sul display vedi quanto è carica la batteria.
Fuori dalla bici: sblocca la batteria con la chiave e portala in casa per ricaricarla. Così la batteria dura più a lungo. Non ricaricare in un ambiente freddo o troppo caldo.
Durante la ricarica non appoggiare il caricabatterie sulla sella, perché può scaldarsi.
Viene fornita con due chiavi.
Specifiche: 48V / 18Ah / 864Wh, estraibile
Compatibile con: QMWheel S20 Pro
(Controlla bene che il componente corrisponda al tuo per evitare delusioni)
Good to know
La batteria della S20 Pro la sostituisci facilmente da solo: sblocca la vecchia batteria con la chiavetta, sfilala dal telaio e inserisci la nuova finché non scatta bene in posizione. Poi richiudi la serratura. Prima del primo utilizzo carica completamente la batteria; una batteria scarica è di nuovo piena in circa 6 ore.
Consiglio: non lasciare la batteria completamente scarica per lungo tempo e conservala d'inverno a temperatura ambiente, così la capacità si mantiene più a lungo. Non ci riesci o hai dubbi? Scrivici pure su WhatsApp al 06 82090642, ti aiutiamo subito.

We specialize in tunable fatbikes and parts. Over 500 happy customers have gone before you. Fast delivery, sharp prices, and customer service that truly thinks along with you.
Can I have my fatbike tuned by you?
Our fatbikes are tunable, and we also supply individual parts to upgrade your fatbike. Please note: tuning is only permitted on private property, not on public roads.
Is a fatbike still legal?
Yes, a fatbike that complies with current regulations (max. 25 km/h pedal assist and a 250W motor) is fully legal on public roads. Tuned models may only be used on private property.
What are the new fatbike rules for 2026?
As of 2026, stricter rules apply around age, helmet requirements, and vehicle specifications. Check our information page for the latest details.
Do you need a driver’s license for a fatbike?
You don’t need a driver’s license for a regular fatbike with pedal assist up to 25 km/h. You do for tuned models above that limit. Keep in mind those are only allowed on private property.
Why buy a fatbike?
A fatbike is comfortable, fast, and ready for any terrain, from city streets to the beach. Ideal for commuting and for fun. And with our tunable models, you get even more out of it.
Do you need a helmet on a fatbike?
A helmet is strongly recommended for your own safety. From 2026, a helmet requirement will be introduced for certain fatbike categories.
What does tuning a fatbike cost?
A tunable controller costs from 98 euro for the V20 family and the Ouxi models, and 179 euro for the GT2000 and GT2000 2.0. Fitting it yourself usually takes less than half an hour. Not sure which part fits your fatbike?
