I have a friend that has the Sun Mountain Speed Cart. He over loaded the cart with too many clubs and the warped the frame and now the wheels are out of alignent and it wants to turn in a circle. I brought back a Bag Boy EZ Fold to the UK (Here is one

for a friend after my visit at Canton. This is a far better cart IMO it folds up better than the Sun Mountain . The tyres are solid (The Sun Mountain has tyres that you have to put air in.) The EZ is far stronger and more simple in design and better all round. My friend with the Sun Mountain is planning to get the Bag Boy .
