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.

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.

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.

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.

Almost rides like a full size bike. Easy to open and close. Lightweight and fits almost anywhere.

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.

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!

Una bicicleta que vale cada peso que pagas por ella, te ahorra espacio y mucho tiempo en traslados en la ciudad y es muy práctica de llevar en el transporte público.

SÃ, es una Brompton original vendida por Brompton y enviada por Amazon. Llega en una caja gigante de Amazon dentro de la cual está la caja de Brompton, donde viene bien protegida la bicicleta. En 15 minutos le pones el pedal, el asiento e inflas las llantas con las herramientas incluidas y puedes salir a rodar.Esta lÃnea A es la opción más económica, y quizá quieras hacer algunas mejoras como ponerle pedales plegables, ponerle un extensor para que ruede mejor plegada o ponerle el bloque para mochilas frontales, pero es 100% una Brompton, te pone a años luz de cualquier otra plegable en comfort, facilidad de uso y plegado y también es muy hermosa.

El envÃo llegó a tiempo y la bicicleta me encanta. Solo que el cierre del manillar venÃa roto.

Me sorprende que con el precio y los estándares de calidad de Brompton se les pase algo asÃ, la pintura parece como recargada en algo y no se llegó al término deseado. Sin embargo, es la mejor bicicleta plegables de todas, siempre quise una y no me arrepiento solo si estoy molesto por la pintura pero se remedia con una estampa o algo
