Yes, like almost everywhere, the beaches in Korea are crowded, this is also demonstrated by the tourism infrastructure present on several of these beaches.

Now, if someone goes outside the holiday time, also like almost at every holiday place, there are few people.

The max height given by Btwin is defined by the length of the seatpost that is long enough for up to 195cm.

But the position of cyclist 195cm tall will be completely uncomfortable with its knees almost touching the handlebar (look at the pictures of the two male riders on the Btwin, these were published by Btwin).

I showed this bike because the famous 16" Fnhon Gust (that Ron seem to uses seldom, most pictures of long distances ride he published show the FSIR Spin 5 with ETRTO406 wheels) is not available in Europe. The two other bikes bi-fold (Fnhon Storm and Literpro Spyder) showed by Ron were never used because still not completely mounted.
