I just bought my first good bike (Electra Townie 21 700c) from
Richardson Bike Mart in Texas and I was pleasantly surprised at the service. There were a lot of lycra-clad people roaming around on Saturday morning and as a fat boy in jeans (with my equally plump wife), I was halfway prepared to be ignored. But I was promptly greeted by a great salesman who helped me and took all the time I needed to make a decision and buy a bike.
It could not have been a better experience. He even took the time to help me install a trunk mount rack I bought from them and showed me how to cinch in the bike for the trip home. Highly recommended.
