There will be some voltage sag that causes this when you demand a lot of power using throttle or high PAS. The voltage goes back up when using less power or no power after a short period. We recommend using the trip meter to better understand range and battery remaining.

One is the 4pin charger connector to the battery. I hate that it isn’t a normal barrel connector. I wanted to purchase a smart charger to limit my battery to charging to 80% or 90%, not the full 100%. Really wanted this for battery maintenance and longer life. I cannot due to this 4pin plug. And the second issue is the battery indicator on the battery AND the one on the main display. Both are misleading and cause confusion. I’m not sure if this is an ebike thing. I own an electric motorcycle and an electric car. They don’t suffer from this issue. The problem is, the battery may be down to 2 bars… i stop for coffee, get back on, and it reads 5 bars. Almost like it magically charged itself faster than the provided charger!? Same with the indicator on the battery. It may read 3 bars, I remove it from the bike, carry the battery to its charger, press the button , and says its full again!? It’s really annoying and frustrating not having an accurate reading.

Even with those issues, I love this bike. If you are willing to let those 2 things go, I would recommend It to anyone.
