an electric motor mounted to the frame; and

a structure disposed over the sub-frame, the structure including members interconnected to one another, the members made of a first material, a bracket secured to an end of a member of the members via an adhesive, the bracket secured to the tunnel, the bracket made of a second material different than the first material.

12 . The electric snowmobile of claim 11 , wherein the first material is steel and the second material is aluminum.

13 . The electric snowmobile of claim 11 , wherein the adhesive is one or more of an epoxy and an acrylic.

14 . The electric snowmobile of claim 11 , wherein the structure defines two fore ends and two rear ends, the bracket including two brackets each secured to a respective one of the two rear ends, the two brackets secured to the tunnel.

15 . The electric snowmobile of claim 11 , wherein the structure defines two fore ends each secured to a respective one of a right suspension and a left suspension of the front suspension.

16 . The electric snowmobile of claim 11 , wherein the members include a left member extending upwardly from a front left end to a left apex and from the left apex downwardly to a rear left end, a right member extending upwardly from a front right end to a right apex and downwardly from the right apex to a rear right end.

17 . The electric snowmobile of claim 16 , wherein the right member is secured to the left member proximate the left apex and the right apex.

18 . The electric snowmobile of claim 16 , wherein the structure includes a bracing member connecting the left member to the right member, the bracing member secured to the left member proximate or at the left apex and secured to the right member proximate or at the right apex.

19 . The electric snowmobile of claim 16 , wherein the structure includes a transverse member extending substantially transversally to the longitudinal axis from a left end to a right end, the transverse member secured to the left member and to the right member.

20 . The electric snowmobile of claim 19 , comprising a left foot rest secured to a left side of the tunnel and a right foot rest secured to a right side of the tunnel, the left foot rest and the right foot rest extending along the longitudinal axis from the sub-frame towards the rear end of the frame, the left end of the transverse member secured to the left foot rest proximate the sub-frame, the right end of the transverse member secured to the right foot rest proximate the sub-frame.

21 . The electric snowmobile of claim 19 , wherein the transverse member is secured to the left member and to the right member via left and right connecting members made of the second material, the left and right connecting members secured to the transverse member and to the left and right members via the adhesive.
