We have read all expert and user reviews on the Brompton P Line Electric. In summary, this is what cyclists think. Published Apr 04, 2025 by Reda Ashour.

12 reasons to buy

The P Line Electric is available as a 4-speed or 12-speed.
Testers and owners say the bike accelerates quickly and power delivery is smooth.
Experts relish Brompton’s easy three-part fold.
The P Line measures just 25.3" x 23'' x 10.6'' when folded, making it easy to carry.
At 34.4lb (4-speed) or 35.94 (12-speed), the part-titanium P Line Electric is lightweight for a folding e-bike.
When folded, users can wheel the P Line Electric using the saddle as a handle.
Testers appreciate the easily removable battery and its carrying bag for storing extra items.
The 35mm Continental Contact Urban tires are puncture-resistant.
Experts enjoy the nimble handling once accustomed to the twitchy feel of the 16” wheels.
A 167lb reviewer achieves 21.5 miles of range using max assist, true to Brompton’s claim.
The P Line Electric comes with a phone mount, front and rear lights, and fenders.
Brompton provides a seven-year warranty on the frame and three-year warranty on the electrical components of registered bikes.

7 reasons not to buy

Experts report a delay of one to two pedal revolutions for assistance to kick in.
The P Line doesn't have a display or handlebar controls for pedal assist. The phone app can be used instead.
Reaching over the handlebars to adjust PAS level on the battery while riding isn't very safe.
One owner says the rear light can drag on the ground when wheeling the bike while it's folded.
Buyers receive bikes with issues such as a bent chainring, a flat tire, and poor shifting.
The P Line Electric is pricier than most folding e-bikes, and so are its accessories.
The brakes lack a motor cut-off switch.

Bottom line

The P Line Electric, Brompton’s lightest folding e-bike, comes as a 4-speed or 12-speed. This version has a titanium rear frame. The renowned, time-tested folding design, low weight, compact size, and smooth ride earn praise. Testers also appreciate the P Line Electric’s simplicity, though this comes at the expense of a display and handlebar controls. Criticisms include delayed PAS activation and potential quality control issues or shipping damage. For commuters who want a lightweight and portable folding e-bike, there’s arguably no better premium option on the market, but the more affordable C Line Electric is a close second.
