In order for you to own the bike after your lease term is over, the residual balance is what remains of the bike's full cost.
You also have the option to pay your lease off early and avoid paying the residual balance if you prefer. You can check our our article on saving money by paying off your lease early.
You can always check your residual by logging into MyAccount online or via our mobile apps.
Your residual will be available to see on your home screen.
