Brompton Wheel Extender for A/C Line – Complete or Separate

Brompton Wheel Extender for A / Classic C Line – Complete or Separate*

Rolling your folded Brompton A Line or classic C Line just got a serious upgrade.
The Easy-Wheel Extender Set replaces the standard rollers with a wider, more stable configuration, allowing your folded bike to roll smoothly behind you instead of tipping or scraping.

Why it works so well on A & classic C Line frames

The A Line and classic C Line are built for everyday practicality, but the original small rollers can wobble or allow parts to touch the ground when moving through stations, shops, or streets. This extender increases the wheelbase and slightly lifts the folded bike, keeping it balanced and protecting the rear triangle and drivetrain.

What you get

• A wider, more stable wheelbase for effortless rolling

• Protection for frame and drivetrain when folded

• Easier handling in shops, trains, and tight spaces

• A lightweight, durable upgrade with a clean, technical look

Made from anodized aluminum alloy and fitted with rubber-coated wheels, this upgrade absorbs bumps, curbs, and pavement cracks far better than the original Brompton rollers.

Available options

✔ Complete set – extender rod, wheels, and titanium bolt
✔ Wheels only

Specifications

• Material: Aluminum alloy rod, rubber wheels

• Bolt: Titanium

• Hole diameter: 6 mm

• Wheel diameter: 60 mm

Compatibility & important notes

✔ Brompton A Line
✔ Brompton C Line (classic rear triangle, pre-2025)

✖ Not compatible with:

• Brompton Electric

• Brompton P Line

• Brompton T Line

• C Line models from 2025 onward with the redesigned rear triangle

Explanation:
Recent C Line frames share a rear-triangle geometry same as the P and T Line. Together with the Electric motor housing, these designs do not provide the correct clearances for an extended roller setup when folded. For stability and to avoid contact issues, this wheel extender is therefore intended only for A Line and classic (pre-2025) C Line frames.
