The britax site says the width is only 22.75". The seat dimensions look the same. The canopy is similar with one less peekaboo window. The fold is the same with a safety button added. The harness looks awesome and a major improvement to the BJ one. The recline looks the same, maybe slightly less. Doesn't have the mesh pocket in back but does have a more accessible basket. MSRP is $249.
Oh yea. Forgot the best part. I sold my BJCM because I kept kicking the brake. Britax moved the back bar up and curved it. The brake is on the right wheel. Looks like I could walk with a full stride with the B-Agile.
