Thanks Jack, this one is the ride on R360, I just replaced the gearbox housings on it, it isn't a big gearbox, just not sure if it will handle the hilly stuff.. Knowing my mate he will want to put a 20hp motor on it to get up the hills and I can see the gearbox as being the weak point. The beauty of them is they are low, flat and wide, and if you fit a flat ride on seat you can drop your body height by a couple of hundred millimeters, all helps
