Depends on where they live. They could probably get a bike and do a few jobs on apps (task rabbit, fiver, etc) to save for an e-bike and expand their area.

I know you can deliver food with e-bikes and if they live in a certain area it might be worth it.

There are a lot of factors though. Even if they look for remote work or online anything, there are so many traps and fake job postings that people get demotivated.
