BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.
We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.
It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.
If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews
We have read all expert and user reviews on the Brompton T Line. In summary, this is what cyclists think.
13 reasons to buy
- Brompton’s innovative three-fold design is quick, easy, and unrivaled.
- At 16.4 to 17.64lb, the T Line is very easy to carry.
- The titanium frame, carbon fork, and supple Schwalbe One tires provide a “fantastic” ride quality.
- Reviewers savor the frame's responsiveness and efficiency.
- The T Line comes in three builds: 1-speed (One), 4-speed (Urban), and 12-speed (Explore).
- Buyers can choose between low and mid-height handlebars. Alternative seatpost lengths can also be requested via email.
- The 12-speed Explore has a 402% gear range.
- Testers and owners praise the T Line’s durability.
- The Urban build’s 4-speed gearing and low weight make climbing hills easy, according to a tester.
- An owner (and his back) appreciates the 8.8lb weight saving over his steel Brompton M6L.
- Owners and testers relish the T Line's quick acceleration.
- Owners, reviewers, and passers-by appreciate the bike's looks.
- The T Line is rated to carry 242lb.
11 reasons not to buy
- The T Line is extremely expensive, and some builds are frequently out of stock.
- Reviewers lament the Brompton’s twitchy steering at higher speeds.
- Owners complain of quality control issues, such as poorly set up derailleurs, under-greased headsets, and slipping seatposts.
- Experts and owners bemoan the noisy rear derailleur’s (Urban and Explore) poor shifting and frequent need for adjustment.
- The T Line Urban’s 4-speed gearing is too low to pedal comfortably above 20mph, say testers and owners.
- Dirt and water can enter the frame and collect in the bottom bracket.
- Owners complain that the Tubolito tubes and Schwalbe One tires are puncture-prone.
- Riders with inseam lengths over 35” will need a telescopic seatpost that costs extra and isn’t carbon fiber.
- A reviewer criticizes the tires’ lack of grip, particularly in the wet.
- The T Line is slightly wider than other Brompton models when folded.
- As with all Bromptons, spares and accessories are pricey.
Bottom line
The T Line is the ultimate folding bike. Expert reviews, owner feedback, and sales demand attest to the success of combining Brompton’s innovative design with premium materials. The incredible utility, “excellent” ride quality, and sprightly performance impress. However, a problem-prone derailleur (Urban and Explore) and numerous quality control issues are especially frustrating at this price. The Urban’s 4-speed gearing is too low, the 12-speed Explore can be hard to source, and some experts question the T Line’s value versus the P Line. Still, for those who can handle the eye-watering price, the T Line is the folding bike to have.
