All the features you love about the BOB Revolution, such as super-easy handling, large comfortable seat with 70 lb weight limit, huge canopy, reclining seat, sealed ball bearings, lockable front wheel, car seat adapters, and great suspension, are standard on both the SE and CE models of the Revolution.
For 2011, BOB has improved the way the infant car seat adapter attaches to the stroller. BOB also made an adapter for the popular Chicco Keyfit Infant, Peg and Graco car seats. The seat was upgraded with new padding, new adjustments for the 5 point harness, and a board for a more rigid back. The hood received an overhaul to make it larger, the fabric was changed to a lighter/more sporty version, a lock was added for when the stroller is folded, the suspension adjustment was upgraded, and the foot-wells were upgraded from fabric to a more durable plastic cover.
So what is the difference between the two? Let us break down the Revolution SE vs CE for you. The first thing you need to ask yourself is what are you looking to do?

If you intend to do more running than walking, or like to venture off the beaten path, check out the BOB Revolution SE (Sport Edition). The Revolution SE uses a 12.5-inch lockable front swivel wheel and two 16-inch rear wheels, all high-impact polymer composite, making it more suitable for jogging and off-road adventures.The SE is built for sport and speed.
Larger tires offer less resistance making it easier to push. The larger wheel diameter also makes it comfortable for the taller user allowing greater distance between the stroller and your stride to limit kicking the axle. The unique mounting system for the lockable front wheel allows you to fix the front wheel allowing for greater tracking while jogging, but also allows for the wheel to “revolve” making the SE a great stroller for downtown and light terrain as well.

Whereas, the Revolution CE uses three 12.5-inch aluminum wheels turning the BOB Revolution CE (City Edition) into a nimble, urban alternative best suited for walking through the park, zoo and city strolling. The Revolution CE is also a couple pounds lighter and slightly more compact than the Revolution SE. Making it an ideal fit for the city where space is at a premium.
The CE could be a great choice for the family who needs something all-terrain to tackle their neighborhood streets in good and bad weather and also wants something rugged enough to handle a hiking trail or a 5K power walk every morning. The CE is not optimized for running due to the wheel size, especially for parents of above-average height.
