Your work computer likely contains personally identifiable information. Microsoft very likely has a significant profile on what you do at work and could conceivably link that to your other identities outside of work.
Are they actually doing that? It's hard to say. Microsoft does have relationships with data brokers like Snowflake Inc. and SCUBA plus its own internal capabilities like Xandr Inc.
Cross pollination is more than possible when employees use personsal devices to login to work accounts. Most of the people that I work with login to Slack on their personal device using Microsoft Entra SSO.

What about riding distances further than one would be capable or willing to ride without a motor?
Many people wouldn't be interested in riding, say, 10-15km each direction especially in a hilly area, but a motor could be a game changer.
The idea that you're not tough enough if you don't pushbike it is just ignorance and ironically more likely to push people into driving or other modes of transport.
