Why is there a “petrol/gas tank” on the bike?

The 'petrol/gas tank' serves as storage. At the press of a button, it opens to reveal 10L of lockable space for valuables, gloves, or a change of shoes. It also includes a USB-C port for charging devices while riding.

If you're using the dual battery RM1 model, the tank houses the second battery, allowing for a longer range (up to 80 miles) and optimised performance.
