Bike Sizing Guide By Brand

Brompton

Good news: Bromptons usually come in only one size.

The extra long seatpost means a Brompton should fit anyone from 4’ 10” (148cm) to 6’ 4” (193cm).

If your inside leg measurement is longer than 35” (89cm) we suggest the telescopic seatpost, which Brompton make for riders with an inside leg up to 39” (99cm). Taller riders might also like to consider Brompton’s highest H-style handlebar.
