1. There are three main driving methods for electric vehicles: one is wheel drive, the
other is mid-drive, and the other is suspension drive. Electric bicycles on the market
are mainly driven by hubs, which are better for rear-wheel drive, and the front-wheel
drive performance is relatively poor.
2. The location of the battery should be considered from the balance of the vehicle and
the convenience of getting on and off the vehicle. It is better to place the battery in
the position of the inclined tube or the riser of the frame. The battery configured is
basically an economical lead-acid battery. Most electric bicycles use 36V12AH lead-acid
batteries; 24V12AH batteries have a shorter driving range, so consumers have fewer
choices.
