Electric Bike - How to Choose
Throttle or Pedal Assist.
When the throttle is engaged the motor provides power and propels you and the bike forward. It allows you to pedal or just kick back and enjoy a “free” ride!
Pedal assist, also referred to as pedelec, is a mode that provides power only when you are pedaling. The pedal assist mode has a more intuitive feel compared to the throttle mode and will give likely provide more range. Some electric bikes come with both.
Generally speaking, the higher the wattage, the higher your electric bicycle power will be.
Voltage x Current = Wattage
ex. 36 volts x 15 amps = 540 watts
In this case, this ebike is approximately 500 watts. How much do you need? Your weight and frequency of hill-climbing will determine the power you need.
The motor is either mounted in one of the wheels (hub motor assist) or it’s mounted at the crank and pedal area (mid-mount), at the bottom of the frame. That means the electronic controls has a sensor that detects how hard you’re pedaling and balance the level of assistance needed. Typically, mid-mount assisted bikes have a reputation for doing well on steep hills.
Lithium-ion batteries are by far the most popular batteries in today's e-bikes. The quality of the battery makes a difference, so choose a reputable battery manufacturer. Batteries degrade over time, but will survive longer with careful use. A full charge typically takes between two and a half to six hours.
