Hopefully her wheel revolutions outnumber her pedal revolutions by at least a factor of 3.

Here's a useless diversion. Assuming she's not riding fixed, I started off with a wheel diameter of 2m. A good single purpose gear would be between 63-73", or somewhat less than 2m. So, a straight 1:1.  Downhill, you probably pedal little, while uphill an average gear of -  what - 45"? so a little less than 2:1. On average, I thought 2 - 3 x sounded about right.

Ratio of chainring to cassette teeth for most folk on 700C on the flat is between 2:1 and 3:1 but usually at the high end. Lower climbing gears drop that. Add in that HK has done quite a few miles on a Moulton (about 2/3 the rollout of 700C), lots on a roadified MTB and a fair number on a Brompton and include racing for several years (big gears) and freewheeling downhill (which is her preference) and they all push the ratio up.
