If I could have one bike at any cost, but only one bike, it would have to be a Alex Moulton Double Pylon. I’ve always admired Moulton’s approach to designing bicycles. Moulton being a very accomplished engineer, disregarded all dogma about how bicycles should be designed, and redesigned the bicycle from scratch. The latest refinement of Moulton theory is a bike that has a reasonable weight, comes apart for travel, performs like a high end road bike, but is fully suspended and can handle light touring loads.
As far as aesthetics, it’s a beautiful piece of hand-crafted machinery. Stainless steel tubing is elegantly brazed together with more joints than any bicycle I’ve ever seen. The carbon fibre fenders are a nice touch as well. The finish is simply breathtaking and just as stunning as any hand built bike by Richard Sachs or Vanilla. The fit and adjustability is also amazing. The double pylon can have its stem raised and lowered and stem length lengthened and shortened very easily. You can have upright handlebars for touring, and then turn around and lower and lengthen the handlebar reach and lockout the suspension for racing. At almost $10,000 you’d expect a bike to do just about anything. I think the double pylon almost can.
