Summary of Reviews

We have read all expert and user reviews on the Brompton P Line. In summary, this is what cyclists think.

17 reasons to buy

The Brompton P Line comes in two builds: Urban (4-speed) or Explore (3x4-speed).

Experts praise the "ingenious" three-stage fold that takes just 15 to 20 seconds.

The P-Line is lightweight at 21.8lb (Urban) and 23.1lb (Explore).

The low weight and compact folded size of 25.3” x 23” x 10.6” make carrying, storage, and transport easy and convenient.

Buyers can choose between three handlebar heights: low, mid, or high. The P Line Explore's bars are carbon.

Reviewers enjoy the comfortable riding position.

An expert relishes the P Line’s agility for navigating tight urban environments.

The vibration-damping titanium rear triangle and fork and rubber suspension block aid in smoothing out rough pavement.

Testers praise the 12-speed Explore’s excellent gear range for climbs.

Reviewers appreciate the P Line Urban's simple shifting compared to the Explore’s hub gearing.

The dual-pivot caliper brakes are responsive and work well in testing.

Reviewers say the tires (35mm) on both builds roll fast and offer good grip.

The extended wheelbase and low center of gravity provide a "well-balanced" ride.

The Brompton's saddle has a soft padded area under the nose for comfortable carrying when folded.

The saddle can also be used as a handle to push the bike on its rollers when folded.

All Brompton frames have a seven-year warranty.

The P Line comes with fenders, a front bag mount, and a bell integrated into the shifter lever.

10 reasons not to buy

With its part-titanium frameset, the P Line comes at a premium price.

The P Line Urban’s 4-speed gearing isn’t suitable for steep inclines.

A reviewer says the Explore's 3x4-speed shifting takes some time to get used to.

According to Brompton, the internal hub shouldn’t be shifted under load.

Two testers report the 4-speed drivetrain skipping gears despite adjusting the cables.

Reviewers say that the steering can feel a bit twitchy.

When folded, the bike can be hard to push across uneven ground and the suspension block sits too close to the ground, according to one tester.

Owners complain the integrated bell is too quiet for city use.

Some buyers complain about the high price of Brompton accessories.

Owners report quality control issues such as a misaligned brake pad, peeling saddle glue, faulty inner tubes, and incorrect rim tape alignment.

Bottom line

The Brompton P Line is a foldable commuter bike with a mixed titanium and steel frameset. It’s available in 4-speed and 3x4-speed options (Urban, Explore). Experts laud its low weight, portability, and overall build quality, especially the folding mechanism. They also highlight the relatively comfortable, well-balanced ride. Complaints are mostly minor, but some owners report quality control concerns. The Brompton P Line is widely recommended and undoubtedly well-suited to urban use and multi-modal commuting. However, it’s a big investment, and some find Brompton's more affordable fully steel lines equally practical.
