I'm all for biking, but please inform my clients (and potential clients) that I will be arriving at their offices covered in sweat, my suit horribly wrinkled, and after two hours during which I was unable to hold a conversation over the phone. If they are ok with that, then I'll use a bike.

For below:

It was 27* last week. I had to travel 10km (as the crow flies) to a potential client's location for a private meeting with their CEO. And we have hills. The concept of me and my suit getting there by bike in acceptable shape is laughable. It might be acceptable for a coder or social media expert to arrive dishevelled, but people expect more from lawyers. I wouldn't win clients.
