19
To determine the XB-420M’s maximum per-charge distance, the testing
environment was:

Rider weight: 180 lbs

Air temperature: 77 ºF

No headwind, smooth, level road, infrequent braking and steady
speed.
Under these conditions, the XB-420M’s maximum range is up to 35
miles.
Frequent braking and acceleration, driving into headwinds, up hills or
with cargo will all cost a lot of battery energy. In these conditions, the
XB-420M will not reach its normal range.
Battery Charging
Be sure to charge the battery completely if you will not use it for a long
period. Ideally, you should charge it every 20 days. Even a healthy
battery will discharge itself slowly. Even with its power off, the XB-
420M Battery state-of-charge will decline gradually over time.
Remember to fully charge the battery before your first ride. The battery
may be low when you receive your new XB-420M.
1) While charging the Battery, keep the key switch OFF.
