Fits in the same holder as the old one. I would order here again

Customer Reviews
Same connector as the original.
Holds its charge well. The box was completely intact. That was worth the wait.
Fits without any adjusting.
Works fine so far.
Replaced in a couple of minutes, all nicely sorted.
Fits the V8 Max as described. Fitting it took me more time than expected. Works just as it should.
I use it every day for my commute, neatly packaged.
Confidence in my bike again.
Off to work without stress again.

Scopri la batteria Ouxi. Questa batteria da 48 volt di alta qualità, con una capacità di 15 ampère, è nota per la sua capacità impressionante e le sue prestazioni quando vai in bici. Con la batteria da 15 ampère sali le colline senza fatica e percorri distanze più lunghe, godendoti una guida fluida ed efficiente.
La batteria si può ricaricare in due modi:
Sulla bici: puoi lasciare la batteria nella bici e ricaricarla così. Guardando il display puoi controllare la percentuale di carica.
Fuori dalla bici: puoi portare la batteria in casa e ricaricarla al chiuso: è il modo in cui dura più a lungo. Evita ambienti freddi o molto caldi per la ricarica. Premendo il piccolo pulsante in cima alla batteria vedi quanto è carica.
Ti consigliamo di non lasciare il caricabatterie sulla sella durante la ricarica, perché può scaldarsi.
Viene fornita con due chiavi
Compatibile con: Ouxi V8, V8 Pro, V8 Max, V8 Pro Max, C80, C80 Pro, C80 Max ,C80 Pro Max, H9, C63,
(Controlla bene che il componente corrisponda al tuo, per evitare delusioni)
Montare una batteria nuova è rapido: sblocca la vecchia batteria con la chiavetta, sfilala dal telaio e inserisci la nuova finché non scatta in posizione. Poi richiudi la serratura, così la batteria non può staccarsi mentre pedali. Prima del primo utilizzo caricala completamente.
Pro-tip: in inverno conserva la batteria al chiuso e ogni tanto collegala al caricabatterie quando la bici è ferma: si mantiene in buone condizioni più a lungo. Non ci riesci o hai dubbi? Scrivici pure su WhatsApp al 06 82090642 e ti aiutiamo subito.

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?

Wide tyres provide extra stability and comfort. Ideal for daily use and varying surfaces such as cobbles and poor road surfaces.
Do you need a driving licence for a fatbike?
No. You do not need a driving licence to ride a fatbike. Fatbikes fall under the rules for normal e-bikes (250W motor and pedal assist). As a result there is no driving licence or helmet requirement.
