>>1010167I've had my Brompton since early June of this year and I have to say this is by far the best folding bike I've gotten my hands on. I've ridden more casual foldies in the Dahon Speed/Mu line (shit, don't even consider), as well as higher end bikes like the Formula S18, and the Tern Verge X10 and I'd say the Brompton really blows all of them out of the water. I live in NYC and no amount of bike locking is gonna keep a Verge X10 from getting lifted, let alone cheaper shit and it's way more cumbersome to bring indoors and store despite being as light as it is (about 20 lbs).
Sure, it's a pretty hefty investment for a foldie but since I've had my Brompton I've literally been saving around $120 a month on transportation costs alone, not to mention the fact my commute to work is actually faster than using public transportation. Sure, it's got some silly little wheels but the suspension helps it ride like any other bike. The steel frame adds a bit of weight in exchange for an incredibly durable build, and despite not being quite as fast as a roadie they're deceptively agile bikes. I've taken mine up to Nassau on a weekend trip and introduction to doing a bit of touring (about 110~ miles) and the Brompton's definitely taken care of me.
Do be conscious of your wheels though, don't run into potholes, and pay attention when you're blazing downhill because you accelerate way, way faster than a roadie will.
