This reminds me of rural Costa Rica. Lots of people going to work on bikes. Our office worker shows up on a bike everyday - she lives about 5 kilometers from the office. One day a week she picks up all the fruits and vegetables for us from the farmers market - and pays a cab to take her to our house. (we pay the cab)
The speed on the bikes is kept pretty low - usually between 10 and 14 KPH it seems. No special clothes.
