Motor system on the crank is very good when the bike through steep inclines. However, a little noisier than the installation of the motor on the hub. Vice versa. Nevertheless, some current technology, hub motor power is not inferior to crank the motor. In the meantime, you can check out the high-quality escooter as well.
It’s hard to say whether manufacturers are using good quality batteries. Battery electric bikes will decrease in quality as usage. unfortunately, there is no more information about the batteries of each manufacturer.
Battery charging cycle
How much do you charge the battery, each time filling into one cycle? The more it’s recharged, then the ability of the battery will decrease. The more often you use and charge the battery in half-empty position also go one cycle. The more often used bike will certainly lower the ability of the battery.
The battery does not like cold
Li-ion battery type turned out to not like cold, power battery power will be lower when cold weather. There is a tip to charge the battery when doing the charger, it’d be better to be done in a room.
There are many types of batteries. Nickel Metal Hydride (NiMH) is commonly used as a rechargeable battery. Sale free and cheap, unfortunately, has a weakness in weight and service life.
Lithium Ion (Li-Ion), Lithium Iron Phosphate (LiFePO4), Lithium Polymer (LiPo), Lithium Titanate (Li2TiO3), there may be another Lithium-based technology. This type of battery has an advantage in longer service life, faster charging, but the main strength is light. Unfortunately, the price of Lithium type batteries is much more expensive.
The magnitude and power of the battery.
The shape of the battery shows the strength and endurance of usage. The larger the power will be longer to use when driving. The larger the size of the battery is also heavier and longer fill it.
When the use of electric bikes for the medium or a few km, the choice can be taken with a medium-sized bike battery. If you want to use a bike with a longer distance, there is no other option to consider a bike with a large power battery.
