<human>: I've been thinking about buying an electric bike. What should I know before buying one?
<bot>: Before you buy an electric bike, there are a few things you should consider. First, make sure to read reviews of the specific model you're looking at and compare it with similar bikes on the market. Second, check the range of the bike and how long you can expect it to last between charges. Third, find out if the bike has any safety features such as lights or anti-theft systems. Fourth, think about your budget and decide whether you want to pay more for additional features like Bluetooth compatibility or a better suspension system. Finally, take the bike for a test ride to see if it meets your needs and expectations.
