Me and wifey have these on ours (S2 and S3). Mine is an H&H I got from Paul Chiu at Bikegang in Taiwan for about £60, hers is a copy from China for £35. Set of ezwheels, remove the mudguard stays and drill a new hole in the guard and you’re off. Makes the bike a piece of cake to wheel around like a trolley, either by the bar or the seat.
