Have a fun and safe journey filestyle1.
I did a 140 mile trip to Mexico and it was a challenge and wore me down. Riding a motorized bicycle is nothing like riding a motorcycle on long trips.
Be sure to carry enough fuel...and a spare plug may not be a bad ideal. And always a tire pump and at least patches; I always carry a new tube.
I also like to carry a spare chain link if you use one and enough tools to do many repairs just in case. Some zip ties or mechanics wire can come in handy so I always carry some with me.
Have a Happy Bike Day
