Tried my ezy2wheel out, and it definitely makes moving the bike easier. The ST is a heavy bike and I found it was difficult to move because you also have to hold it upright, and I was always fearful that I would overbalance it and it would lay down away from me.. The ezy2wheel takes away that need to balance the bike while moving it and makes me much more confident in turning the bike around.
Putting it in place and removing it is a piece of cake, place the ezy2wheel next to the side stand, move the bike upright with your hip and slide it under the base of the side stand with your foot. Same to remove it, upright bike, move the ezy2wheel out with your foot, settle the bike back down on to its side stand. I keep mine in the pannier with my bike tool kit.
I've got a narrow garage so it doesn't greatly reduce the number of turns I have to do, but each turn is much easier. The instructions recommend holding the left handle bar and the left back hand grip, this is fine for backing the bike and turning it towards you. When moving the bike forward and to the right I move myself forward in relation to the bike and hold both handle bars. I find it harder to turn the bars from full left to full right, the bike is leaning towards the left and it seems as if there's more weight on the bars, that's why I use both hands on the bars for a forward right turn.
And as I said, in the narrow garage I still have to do a number of turns. But the ezy2wheel works and makes each turn easier. I tend to back it with the front wheel turned left and move it forward with the front wheel turned right, so the overall movement of the bike is an eventual clockwise rotation.
All in all, a smart little bit of kit.
