Embodiments relate to exercise systems, and more particularly to adjustable exercise cycles. In accordance with at least some aspects, a stationary exercise cycle includes an incline mechanism that adjusts an incline of an upright support structure. The incline mechanism is aligned with a portion of an upright support structure on which a handle bar assembly is mounted. In some cases, the exercise cycle includes a console that can be rotated for viewing when not riding on the exercise cycle. The exercise cycle can also include an adjustment mechanism for adjusting the position of a seat or the handle bar assembly. The adjustment mechanism can include a cam-based locking mechanism for selectively securing the seat or handle bar assembly in place.
