I have a Powaglide buggy which I bought a while ago as I wanted to convert it. Has great potential. It has a rotating chassis which handles well off road.
It's quiet, so no scaring off the quarry, powerful and twin batteries so goes for ages.
Specs as follows:
Buggy Weight: 68kg + Batteries, Heaviest Individual Part 32kg, Max Load 180kg Max Length: 180cm Max Width: 72cm Max Height (to top of seat): 112cm Chunky Wheel Size: 33cm * 12.5cm Handlebar Width: 52cm Largest Part Length: 72cm Gearbox: Forward / Reverse Gearbox, Easy Click Gear Change. Motor: 24V DC 800 Watt Motor, Speed 0
