Do the three size options have different bicycle frame sizes?
The situation is to check whether the size of the frame body itself differs, as it is divided into three sizes according to height.
The main frame sizes are all the same, and the handlebar height and seatpost specifications are configured differently to match the rider's height.
There is one body, but it is divided into three setups[1]. The G Line 8-speed model introduced together by BROMPTON and CAYL has the same main frame size for all, and distinguishes sizes by the steering section height and seatpost specifications[2]. This is because the comfortable resting position for the hands and the saddle height suited to leg length vary depending on the rider's height.
The Small option, with a recommended height of 152~168cm, combines a Low handlebar and a standard seatpost[3]. The Medium option, based on a height of 168~183cm, includes a Mid handlebar and an extended seatpost that is longer in length[4]. The Large option for the tallest height of 183~198cm consists of a High handlebar and a 2-stage adjustable telescopic seatpost[5].
Without having to worry about measuring frame sizes, choosing based on the range your height falls into allows you to get the proper riding posture.

Specific selection criteria at the boundary where recommended height ranges overlap, such as a height of 168cm or 183cm, have not yet been confirmed.
