Here is something that really needs doing, a bike golfcart. I like to walk, and hate to ride, but there is a place for assistance as people get older. Plus on some courses set up for carts, there can be long walks between the holes. A bike golfcart would just be a bike, possibly, on any course that uses the 90 degree rule. You are stuck on a path anyway, so why not. For a cart that would really be used all over the course, probably a trike format with very large ballon wheels would be best.
On some courses the terrain is too fierce, but that isn't always the case. I would say almost all the courses I have been on could be biked. A lot of the courses I have seen that had terrible terain have good cartpaths. But god help you if you need to take a straight line on foot.
There is no question it would be practical. It has probably been done. The main problem would be that golf carts are major revenew producers, and something one could easily bring to a course, and not take a cart, would not be welcome.
Anyone seen this?
