Brompton Wheel Extender for P/T Line – Complete or Separate
Brompton Wheel Extender for P/T Line – Complete or Separate
Looking for a smoother way to roll your folded Brompton P Line or T Line? This Easy-Wheel Extender Set has been voted one of the most useful upgrades for Brompton riders—and for good reason.
When folded, your Brompton becomes a rolling companion. But the default rollers often fall short—especially for the lightweight yet performance-driven P and T Line frames. That’s where this extender comes in.

What it does:
-
Extends the wheelbase while folded for better stability
-
Keeps the rear triangle and frame safely off the ground
-
Makes rolling your folded bike feel effortless
-
Prevents wear on the frame’s aluminum ring
Why it's perfect for P/T Line riders:
The P and T Line’s lightweight frames benefit immensely from this extender’s added support. Built with aircraft-grade aluminum alloy and durable rubber wheels, this set gives your ultralight Brompton the sturdy support it needs when folded.
Whether you're upgrading from the original rollers or just want better performance while walking your bike through stations, shops, or streets—this extender is a no-brainer.
