I’ve never found the bike itself to be a good investment. Over its life, you will spend more than its initial cost in maintenance and repairs. And in the end it will be worth almost nothing. However, owning and riding a bike is a great way to save money, if it replaces a car or public transportation. Plus you’ll get a bit of fresh air and exercise along the way. The bike you are looking at is unfamiliar, but it sounds like it is appropriate for your situation. If it has knobby tires, replace them with smooth street tires immediately, and you’ll be much happier.
