Tawanda Maswanhise opened his account for the season with two goals
A Motherwell side bereft of injured Lennon Miller was held by Clyde in their Scottish League Cup opener but took the bonus point by winning the penalty shootout.
James Hilton struck from outside the box to give the League 2 hosts the lead.
Tawanda Maswanhise soon headed the Steelmen level and his shot early in the second period turned the tie on its head.
Liam Scullion nodded the Bully Wee back on terms.
In the shootout, Logan Dunachie's effort from 12 yards was saved by Calum Ward to give Premiership Motherwell a 5-4 winning lead in Jens Berthel Askou's first match in charge.
Elsewhere in Group G, Greenock Morton won 4-2 away to Peterhead.
Meanwhile, midfielder Miller faces 10 days out with a knock picked up in a closed door game against Carlisle United. Miller, who has been linked with a move away from Fir Park, is unlikely to feature in Well's three remaining group games.
