Bigger battery is the entire reason to buy this. Charge once a week for a 12-mile commute.

Frequently Asked Questions

How much more range does the AOVOPRO BK900 have than the BK520?⊕

The BK900 uses a 48V 9Ah battery versus the BK520's 5.2Ah — a 73% increase in capacity. In practical terms, this extends range from 35-40 miles to 45-55 miles in pedal-assist mode. For daily commutes of 15-20 miles each way, the BK900 can go 2-3 days between charges where the BK520 would need daily charging.

Does the AOVOPRO BK900 have the same app as the BK520?⊕

Yes. The BK900 uses the same companion app as the BK520, with the same route tracking, battery monitoring, speed data, and remote lock features. The additional range means you get more useful data per charge cycle.

What is the top speed of the AOVOPRO BK900 and is it road legal in the UK?⊕

The BK900 reaches 22 mph in pedal-assist mode. This exceeds the UK EAPC 15.5 mph limit, so it is not road legal on UK public roads in standard form. In the US, it qualifies as a Class 2 or Class 3 e-bike depending on the assist configuration used.
