Differences between road bikes and mountain bikes are obvious for many reasons so it makes sense that a bike for commuting would be a bit different from both. Mountain bikes are most typically designed to put the rider's weight a bit more forward thus adding some pressure to the front tire for more grip or traction. What has become termed a "more aggressive riding position" varies from bike to bike. These days we see fat bikes designed with a much more upright posture lending comfort and ease of expression to a fun relaxed ride that for all purposes does not lack performance.
This illustrates the point of finding a proper handle bar for bike commuting performance, pleasure and comfort. There are many variations on handlebars these days, sometimes difficult to keep up with all the latest designs and added features. However there are some tried and true handlebars that are simple in design that have been around for quite awhile with proven satisfaction, popular with many types of bike commuters and available in the most common stem mounting diameters of 25.4mm, 26.0mm and 31.8mm. Remember to choose the right diameter for your particular stem or if necessary consider replacing the stem to get your preferred handlebar.
Some of these types of handlebars are available in different widths to accommodate various shoulder widths in order provide a nice custom feel when added to a commuter bike. Other mountain style handlebars like the one pictured above provide options for cutting to width as well as typically being available in 31.8 mm clamp diameter.
