Having a roadside tool kit with useful items is useful, especially for longer trips. The Metacycle can't allow someone to ride all day and was designed to be almost maintenance-free, thanks to the hub motor instead of using a traditional chain, belt, or shaft drive. Even so, you may want to know what tools are necessary to perform specific actions.
5 mm Allen wrench - seat
T40 Torx wrench - battery cover
T50 Torx wrench - battery brackets
In addition to the tools above, having these extras may help you in case you get stuck somewhere.
Tire patch kit
Wire cutter or knife - in case the alarm module fails
Zip ties
Vice grips - acts as several small wrenches, can be an emergency brake lever
