Given the above advantages, you’d think the TT-R50E would totally bury the PW50, right? Not so fast. The TT-R50E is actually for slightly bigger kids, owing to its 21.9-inch seat height (a significant 3.2 inches higher than the PW’s seat), a longer wheelbase, and larger dimensions. So, in their own way, the TT-R50E and PW50 are like oranges and apples. But which is which? With its removable peel and neat segments, we’ll match the orange to the sophisticated TT-R50E, and let the simpler PW50 be the apple. Now, that said, enough about fruit!
