The Bugaboo Bee Plus will be hitting stores soon (April I hear) and there are quite a lot of new features. The designers focused mainly on resolving all issues folks had with the Bee, which will be replaced totally when the Bee Plus hits the stores.
New features include a new height-adjustable backrest, a new ergonomically shaped and reversible seat, a height-adjustable handlebar with ten positions, and new rubber material for the wheels.
