When we first brought home our new E-trek, the taller members of the family kept bumping their heads on the front and rear cabinets. Luckily there is a simple fix available at Babys R Us, and I assume many other stores that have a child-proofing section. We purchased foam self-stick protectors, intended for the edges of coffee tables, fireplaces, etc. and placed a strip on both the front and rear cabinet. Problem solved!
