While getting a bicycle hand-built to your exact dimensions can indeed ensure a custom fit, it can also be quite expensive, plus that bike will be made mainly with one type of riding in mind. That's part of the reason that UK frame-builder Mike Hickman created the Hickman Bike. The idea behind it is that using an "off-the-rack" bike, riders will still be able to get that exact fit, and will also be able to adapt it for different types of riding.
First of all, it is of course possible to adjust some things on a regular bike, without swapping components – these include the height, angle and fore/aft position of the saddle, along with the height and angle of the handlebars.
Using the Hickman Bike's telescoping/pivoting frame sections, those same variables can likewise be adjusted, but over a much wider range. Additionally, it's also possible to move the handlebars fore and aft.
All this adjustability means that the "cockpit" can be lengthened or shortened, or moved laterally in respect to the rest of the bike. Some things do stay set, however, such as the head tube angle, chainstay length and bottom bracket drop.
The frame is made from TIG-welded chromoly steel. If you want one, and are willing to supply your own components, Mike will make you one for £2,000 (about US$2,780). Complete bikes are also available.
