Mountain bike chargers determine how fast you can get back out on your e-bike at 100% charge capacity. It's important to note if you are only going out on 1 ride per day, and you are able to charge your eMTB at home between rides, the rate at which your bike charges is not going to have much impact as all chargers will fully charge between 2-13 hours(from fully drained). However if you are going out on long frequent rides throughout the day, and charging in between these rides, the rate at which your bike charges can impact your time spent in the saddle.
Chargers connect to a port, typically next to or above the motor. They also often connect underneath the downtube.. the port situated at the top or bottom of the frame. This guide covers numerous chargers provided by our brands.
