Know your Brompton line

Steps to Identify Your Brompton Line:

1. Look for Branding and Labels: Many Brompton models have labels or decals indicating the line.

2. Look for Specific Features:

   • Gears: The number and type of gears can indicate the line.
     • A Line: 3-speed gear system.
     • C Line: More versatile gearing, often 2, 3, or 6.
     • P Line: Combination of internal and external gears, typically 4.
     • T Line: High-end and customizable gearing.
   • Material: The use of lightweight materials (e.g., titanium) is more common in the P and T lines.
   • Additional Features: Mudguards, racks, and other accessories are standard on C, P, and T lines but might be minimal on the A line.
     
     

3. Frame and Component Details:

   • Weight: Lighter weight indicates P or T lines.
   • Component Quality: High-end components and materials are a hallmark of the T line.
   • Battery and Motor: If your bike has a battery and motor, it’s an Electric Line
