My wife and I each have Vado 3.0’s and are riding in the Solvang Half Century in a couple weeks. We were going to ride our Tandem, but couldn’t get into shape quickly enough. Solvang is hilly and I’m concerned about the battery range. On some recent training rides I’ve inflated the tires to 75psi, which is the max rating on the tire. We also plan on leaving them in ECO mode, except for the big hills. The chains will be freshly cleaned and oiled also. Any other suggestions to maximize our range?
