Electric bikes require batteries in order to function. Some batteries need to be fully charged for three to five hours. Larger-sized batteries with higher capacities need to be charged longer. E bikes have rechargeable lithium-ion batteries that need to be charged sufficiently in order for it to last a day. An e bikes’ battery life are measured in terms of watt hours. When a battery’s watt hours is higher, its capacity is similarly so. A few e bikes permit the use of two batteries, thus helping extend a ride’s length. Also, if in case one battery dies, a backup is easily available.
The style of how a battery is mounted on an e bike is critical. When placed on a seat tube or downtube, its position will produce a solid center of gravity. As a result, the ride will be more balanced compared to if the battery is mounted near the front wheel or at the back. The e bike will also appear sleek. Batteries installed in the frame also saves space to allow additional cargo in the front triangle. Compared to internal batteries, external batteries are more convenient to replace.
