Removable battery is not the only factor that makes model "N" Electric Scooter special. Rear drive wheel and suspension on both wheels will add that much needed comfort on the brick roads of Singapore's shared paths. Solid soft rubber wheels will never deflate half way through your trip providing you much needed reliability.
Joyscoot can be easily found in Singapore Visitor Centre @ Esplanade Waterfront. Take a bus or cab to Esplanade Mall, then walk out to the waterfront, turn right and you will find Singapore Visitor Centre and Joyscoot right next to Jubilee Bridge.
