How to go to Hong Kong by bike? Please elaborate.

Bicycles can go through customs. It is the easiest to fold. You must take the train at Luohu Port, but if you can't ride a bike, Rome will be fine, but you have to pay a few dollars to take a yellow bus when crossing the border, and you can't walk there. You'd better take your bicycle bag and take it there as luggage.

When riding a bike in Hong Kong, remember to equip it with front and rear lights and turn it on at night, otherwise it is illegal. In addition, roads and overpasses are generally not allowed, and other traffic rules are basically the same as cars. Running a red light will still be fined, of course, the law enforcement is relatively loose.

Bicycles are not allowed to be used in cross-harbour tunnels, expressway and overpasses. In fact, urban roads are very busy and there is no one-way street. It is very dangerous to use the road by car. Some towns in the New Territories have been changed to one-way streets.
