The sensor itself is in the rail with, I assume, a magnet in the seat. But no, not a Concept2, it's a Horizon Oxford IV. £600 new several years ago. Luckily I bought it second hand, but still, not the bargain I thought I was getting! I did wonder how common this ruse is on other machines. Anyway, doing something on the flywheel might make an interesting Raspberry Pi project one day I suppose, although calibrating it to any meaningful distance travelled might be a problem. Suppose I'd have to get a professional rower in to estimate what it felt like!
