Is that 12 miles a day a single commute? i.e. 6 miles each way?

Personally I'd just ride my bike for that and if I was unwilling or unfit to cycle 12 miles a day[1] I'd go with an electric bike.

(That would actually save me time I would otherwise spend training but I realise I am an odd outlier).

1. Not judging here, everyone has their own fitness levels and goals.
