Using this electric trike is a breeze. You can start by using it like a normal trike without the electric boost. When you need some extra help, just switch on the electric assist. If you're feeling really lazy, use the thumb throttle and you won't have to pedal at all. For charging, you can leave the battery under the rear basket or slide it out. It's up to you. Remember, when changing gears, you can do it even when the trike is stationary thanks to the great gear hub. To keep it in good shape, regularly check the tyres for wear and tear. Also, clean the trike after riding on dirty roads. If you install two batteries, make sure they are both properly connected. Have fun riding!
