65Ah capacity and the lineup's top range

With a total capacity of 65Ah split across two batteries (35Ah and 30Ah), the X8 reaches a range of up to 220km, making it the option with the longest possible distance among all cargo bike models in the lineup. This capacity matters for riders doing long-distance deliveries without frequent charging opportunities.

Heavy-duty cargo frame and load distribution

The reinforced steel construction is built to handle repeated loads without deforming over time, and the low positioning of the rack keeps the center of gravity stable even at maximum allowed load.

Recommendation: due to the high curb weight and large load capacity, check tire pressure and hydraulic brake condition frequently for optimal safety.

Frequently Asked Questions about X8

Why does the X8 have much longer range than other cargo models?

The X8 uses a dual battery system with a combined capacity of 65Ah, significantly larger than the standard 13–25Ah configurations used on other models, which explains the extended range of up to 220km.

How heavy is the X8 and does it affect handling?

The net weight of approximately 54kg is significant, typical of heavy-duty cargo models with long range. Low-speed maneuverability can be more demanding compared to lighter models, but cruising stability is good thanks to the low center of gravity.

How long does it take to fully charge both batteries?

Fully charging the dual battery system takes between 7 and 8 hours using the original charger supplied with the bike.

Are additional rack options available?

Yes, the X8 is available with additional rack options on request, for riders who need extended carrying capacity beyond the standard configuration.
