    • Great Bike, Just Not the Right One for Me
Color: White
I absolutely loved the Brompton A Line 3-Speed it’s compact, lightweight, and perfect for urban commuting. The folding mechanism is smooth and convenient, and the ride quality is excellent. That said, I decided to return it only because I realized I needed the 6-speed version for more versatility on hills. There was nothing wrong with this bike at all it’s a fantastic option if a 3-speed setup suits your needs! ... show more

    • It's exactly a Brompton.
Color: White
If you are willing to drop $1,200 on a Brompton, you already know what a Brompton is. This isn't a bike you buy randomly, or on a whim. You know what you are buying. This is exactly that. It's the entry level Brompton with a 3 speed internal hub. The only things that are missing (that I miss) from the C line is the bag hook on the front, and the folding pedal. I got the bag hook on the front for $50 and I don't, honestly, see the need for at the folding pedal. If I'm flying, I can just take the pedal off, and if I'm bringing it in the house, the folding pedal isn't really a big deal. So yes, this is Brompton trying to go more mainstream by offering a less expensive, direct to the customer, sales process on Amazon. Worked great! Good on them! ... show more

    • A B75 with a new coat of paint (and a new name!)
Color: White
This little guy folds up small and is easy to move around when a full sized bike just won't fit. I suspect this 3-speed setup is really just what most people need. The "C-Line" is better, but at the time of this wring you'll pay 50% more than the A-Line for what amounts to twice the gear options and a newer iteration of the components. Even the "entry level" Brompton here is still a really well manufactured, clever design. If you're looking at the "A Line" and wondering what's up with Brompton's new naming convention, you should know that this is just the new branding for the "B75." I was surprised to see this listing on Amazon, as Brompton hasn't historically sold bikes here. I was a little nervous about purchasing for that reason, but I wrote to Brompton support and they confirmed this is indeed their official listing. Shipping came straight from New Jersey, presumably Brompton's warehouse there. It wasn't through Prime, but it was almost as fast. ... show more

    • It's my pocket bicycle
Color: White

It's a cool little bike. I don't take it on planes, busses or trains. In fact, I live in suburbia and probably could have gotten something larger and less expensive, or just a bike rack. But I am still like my Brompton - it is fun just to through it into my civic to take to a nearby bike trail or take it on a family trip when we go to a bike friendly historical town, like Charleston SC, or Savanna, GA. ... show more

    • Better than expected!
Color: White
So much better than I expected -- lightweight, durable, and very easy to ride! I was worried that I would not be able to ride long distances due to the small wheel size. That is not a problem at all! I have to admit that I fought with my Brompton initially to get it unfolded. Finally found on the internet that the seat must be raised to a certain height to allow the bike to unfold. No force is needed. Begin short, I need to raise the seat higher than riding position to unfold. With that problem solved, I am now a pro after only 3 practices. ... show more

    • Amazing bike for SO many reasons!
Color: White
Review Image by brittney m hansen brittney m hansen
Easy to setup, easy to travel with and overall awesome! Instructions were clear and easy to follow - visual guides across each step which I appreciated! My favorite part is that I can bike anywhere now - it’s just a quick fold and as easy as placing this in my back seat - no bike rack or anything. And I can bring it into coffee shops or inside my house without having to worry about a bike lock outside. It’s perfect for someone with a smaller apartment! Rides smooth and I really enjoy how sleek it looks! Very happy with my purchase & want to get one for my fiancé now. ... show more

Unboxing and initial set up was quick and easy. It took about 15 minutes total and that was at a leisurely pace and reading all the directions. The instructions for unfolding and folding the bike are clear and only took a few minutes the very first time. After doing it a few times it’s a snap. The bike is quite light and easy to tote around. It has 3 gears but with enough range that uphills aren’t a struggle. The bike handles well and is very responsive. You won’t be disappointed. I can’t wait to shop the accessories including a bag that can hang from bike. ... show more
