Hi there. I'm new to biking, and have grown up with "mountain" bikes my whole life. Recently I've decided to become more healthy, and bike to work and home. Calculated the mileage and it's roughly 150 kilometres a week. I'm looking for a bike that is of ultimate comfort but has speed and versatility. I figured this was a great place to post, although 150km may not be long distance to most of you The land is generall flat, with moderate hills. Nothing to terrible. I thought I'd give it a shot! Any bike reccomendations, or advice in general? I'm going to need all the help I can get, and look foreward to any and all advice/recommendations I can get! Thanks so much!
