I purchased the I4m golf buggy play 2 rounds a week on it our course is quite undulated but no problem with the I4 m golf buggy, Every one at my course is in envy of this buggy and I get plenty complements on it I updated the battery system to the lithium and I am amazed how little discharge used when I travelled to the course and back then 18 holes on a par 72 golf course checked the battery and still had 79% charged left, Roy Moor who I bought the buggy from is very willing to help at any point and will answer any questions asked of him, I would recommend contacting Roy at I motion caddy’s and highly recommend the I4 m buggy it is a great buggy to ride.
