The bike shops here in central CA have plenty of hybrids and townies. Bike commuting for exercise is popular. Not LCF... it’s still the burbs. Your town needs to be on board. If there’s nowhere to ride a commuter bike there’s no sense in doing it.
There’s a bike shop here in Folsom called Practical Cycle. They were once located in old Sacramento where they sold Yubas and Bromptons. Since moving they have recast as a Pedego dealer. They have every commuter accessory required.
