I wouldn't get a front suspension to ride on the road. The best bike you can get on Amazon for that price is the Diamondback Century 1: https://www.amazon.com/Diamondback-Bicycles-Century-Complete-X-Large/dp/B013WETMPO/ref=sr_1_1?srs=9102008011&ie=UTF8&qid=1473858034&sr=8-1&keywords=century

I like the endurance road geometry as it will allow you to travel fast and comfortably. The Century is great for commuting because it comes with rack/fender mounts and disc brakes which are nice for all-weather commuting.
