In terms of battery life, there are a number of factors (speed, weight, incline, the assist level) that will dictate how long the battery will last, but it’s not unusual for the battery to be helpful for approximately 20 miles. Keep in mind that all of the trishaws can still be pedaled without the help of the battery, just like a non-powered bike, through muscle power alone. Many of our pilots only use the battery for starting and for hills. A fully-charged battery can be used in many cases for hours, so always keep in mind that some passengers may tire more quickly than others. Make sure to ask them frequently how they are doing.
