It allows for up to 70 km of range on a charge, or about 45 miles, and has a charging time to 80% of 15 minutes. The base Yadea Q1 with sodium-ion battery costs the equivalent of $450 USD, while the top-end Q50 model with traction control goes for $590.

The 24Ah sodium-ion battery that Yadea uses comes with innovative hard carbon electrodes that allow more than 1,500 charge cycles, or about five years of usage if the scooter is charged almost daily. A big advantage of its sodium cells is also the fact that they can retain more than 92% of their capacity even when operating at -20°C (-4 Fahrenheit) and discharging at those freezing temps.

The ho-hum part is that the first e-bike with sodium-ion battery only carries a load of up to 75kg (165 pounds), but urban scooters like the Yadea Q1 are usually used en masse in Asia by a younger crowd where that shouldn’t be much of a problem.
