Every Bike Angels point you earn is added to your monthly and lifetime point totals. Each of these point totals will earn you different rewards! Monthly points, which earn membership extensions and free day passes, reset on the 1st of each month. Lifetime points never reset.
P.S. Did you notice "Annual Points" on your member profile? These are points that reset each new "riding season" on April 1st. But because this is the first year of Bike Angels in Ford GoBike, your Annual point total should always match your Lifetime point total...until April 1, 2019.
