Can you ever stop finding things to do on a Brompton? Those little flexible bikes keep on delivering the goods! Placing a little child on a safe platform-like extention as pictured gives the little one security and confidence when riding with one of his/her's parents or other caregivers-much more than seating him/her in the back. Plus good memories of riding on a folding bike-enough to last a lifetime. With the addition of hopefully encouraging the little one to bike for his/her entire life!
