Using your Watt Wheels City LS Electric Trike is a piece of cake. You can ride it just like a normal trike. When you feel tired or need a bit more speed, turn on the electric assistance. To start using the electric power, you can either use the pedal - assist mode or the thumb throttle. The reverse feature is handy when you need to back up. For battery charging, if you want, you can leave the battery under the rear basket and charge it there. Or, you can slide it out for charging. When installing two batteries, remember it will only use one at a time. As for maintenance, keep the trike clean, especially the gear hub and the battery area. Check the tire pressure regularly. If you have any questions about speed or power limits, you can use the programmable display to set them according to your needs.
