What kind of lock would you recommend?

In order to minimize the chance of theft, we recommend that you get a quality u-lock to protect your bike when you're not there. These are typically metal bars in the shape of a U which are stronger than coiled locks which can be easily cut. As the battery is typically the most expensive component on your electric bike the Beach Bum is fitted with a lockable battery for safety. The lockable feature allows you to either secure the battery in place while you lock up your ebike or unlock it and take it with you.
