The 20-year-old joins the Trotters on a free transfer after he was one of two players to leave crisis-hit club Rangers to help ease their financial worries. Wylde helped the Gers to the Clydesdale Bank Premier League title last season but will be thrust into a relegation fight with the Trotters.
Manager Owen Coyle believe Wylde's arrival will boost his side's hopes of beating the drop, with Bolton just a point above the relegation places . He said: "To capture a player of Gregg Wylde's talent is a fantastic bit of business for the football club, especially given the interest that was shown in him by a number of other Premier League teams."
He added: "He is young, quick and exciting, and has played at a very high level with Glasgow Rangers, both domestically and in Europe.
"Gregg is a creator and scorer of goals. We are thrilled to have him on board and everyone is looking forward to working with him."
The Scotland under-21 international's move is not yet assured, however, with the deal still subject to authorisation and clearance from FIFA.
Bolton were able to make their move for Wylde after he walked away from Rangers, who entered administration last month.
Wylde and Mervan Celik left Ibrox to help save the club financially, with the winger telling the Scottish Sun after his exit: "It was dragging on and on so I just decided to put my hand up to go to try and save some jobs. I just wanted to help the club.
"There are people in there who need a wage more than I do right now.
"My wages might not save a lot of money in the grand scheme of things but I'm just glad to be able to help in some way."
