Same couple as in OP 
Looks like Lyft is trying to foster a positive image for wearing helmets
The only online images I can find of scooter users wearing helmets are these Lyft images.

.
The man is wearing a backpack, which is not prominent in the OP photo.
These are both photos attached to Lyft e-Vehicle Products being used in their Denver pilot program.

1. 18.6 miles long-distance range on a single full charge measured under the following conditions: 165 lbs loads, 77°F weather temperatures, a flat road without strong winds, power saving mode, and 9.3 mph constant speeds. Results may vary based on different weight loads, temperature, wind speed, operating habits, and other factors.

2. Power consumption is estimated at 0.335kWh based on electricity metering equipment.
100km standard power consumption calculation: Power required for a single full charge (0.335kWh) ÷ typical mileage (30km) x 100km.

3. 13.1-ft braking distance measured at 12.4 mph speeds, 68℉ weather temperatures, 165lbs load, tire pressure of 35 PSI, and on flat dry asphalt.

I couldn't find a parts list, but similar electric bicycle batteries cost $300 to replace. 
I have to wonder about the theft of batteries -- there is no mention of how the batteries are locked or secured.
.
Several articles say that nobody is publishing the safety test data on these batteries and scooters or what kinds of tests they have been subjected to. Recall the hoverboard fad that disappeared after units were exploding or catching fire during charging or use.
