A seat adjustment device for a bike includes a holding base adapted to be engaged on a top of a support tube for a seat. First and second clamp blocks are received in the holding base. The second clamp block is moveable relative to the first clamp block. A bar-clamping space is formed between the first and second clamp blocks to clamp a support rod for the seat. An resilient member is provided between the first and second clamp blocks to bias the first and second clamp blocks towards an inner wall of the holding base. The first and second clamp blocks may be free to pivot around in the holding base, allowing the seat to be adjusted at a significantly increasing angle. |
