I have a 97 EZGO electric golf cart.
I bought it used for 1000.00 when it was 3 years old in 2000.
I've replaced the batteries twice and the forward/reverse switch twice.
I have put a set of heavy rear springs to support the back seat/flat bead.
I use stock sized tires but replaced the rib tires with turf tires to keep the load on the electric controller the same.
If you put oversize tires/rims on an electric and don't beef up the controller, cables and F/R switch with heavy duty versions, the stock stuff will melt and leave you in the middle of nowhere......yeah, melt....as in get hot enough to melt the solder out of the lugs on the end of the cables.
Am in the process of resurrecting B'Ugly (pronounced be ugly) for my hunting buggy.
I built this thing from scratch about 7 years ago based on shortened VW beetle IRS.
