If you want to know just how fast you can go on your vintage fixed-gear conversion, but can’t bear to put an ugly plastic computer onto your beautifully curated bike, this concept bicycle speedometer could be right up your bike-lane. It comes from Estonian designers Redfish Creative and, despite some flaws, looks pretty gorgeous.
The computer works just like any other wireless bike-computer, with a fork-mounted sensor that detects a spoke-mounted magnet as it thrum-thrums past and beams the info up to the head-unit on the bars. The difference is in the interface which looks more Gran Turismo , all analog dials and twisting knobs.
The speed is shown with a needle on a dial and the mileage (or, in this case, kilometer-age) reads out on a retro-style odometer that can be switched from trip-distance to total distance at the slide of a switch. The wheel-size, which needs to be input for this kind of rotation-counting setup, is dialed in via a knob on the magnet-sensor unit.
