Can I remove the BK520 battery and charge it away from the bike?

Yes. The 48V 5.2Ah battery is removable, so you can charge it on or off the bike. That is useful if the bike is stored in a garage, shed or communal area without a convenient socket.A full charge is listed at around five hours.

How much assembly does the BK520 need when it arrives?

It is not normally a completely built bike in the box. AOVOPRO lists the front wheel, pedals and seat among the parts to fit, with tools, charger, battery keys and manual supplied.

What is the real reason to choose the BK900 instead of the BK520?

Range. The two bikes share the same basic 26-inch format, 350W brushless motor, suspension and disc-brake concept, but the BK900 uses a larger 48V 9Ah battery instead of the BK520's 5.2Ah pack.If your journeys are short, the BK520 is the simpler value choice. If you regularly ride farther between charges, the BK900 makes more sense.

Is the Aovo Pro BK520 Electric Bike easy to assemble?

The Aovo Pro BK520 Electric Bike 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 Aovo Pro BK520 Electric Bike water resistant?

The Aovo Pro BK520 Electric Bike 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.
