• on rare occasion. A remedy for this is using a sensor less controller. It may be a better
alternative to replacing the hall sensor or motor completely.
• To recap, this issue can be due to a number of reasons, but we will start with the most likely
and simple fix.
• 1. The brake switch is stuck on. Check your rear stop lamp to see if the light is activated by your brakes.
• 2. The kill switch or kickstand switch (if equipped) is stuck on.
• 3. The controller needs to be replaced.
• 4. The throttle wire has a loose connection or needs to be replaced.
• It is not common to be a motor issue because it is typically the most robust electrical component on
the vehicle.
Q. The battery voltage/gauge/meter drops when I ride. Why does it do that?
• As you draw power from the battery you will get some voltage drop that will settle up once you stop.
It is recommended that you charge the bike as frequently as possible to maintain battery capacity for
both speed and range. As your voltage is depleted the Electronic Vehicle speed will lower
incrementally.
Q. What should my battery voltage reading be when it is full?
• It is recommended for all Electronic Vehicle owners to have a multimeter to read the voltage.
• For 48V bikes the voltage range when full is typically around 52V-53V
• For 60V bikes the voltage range when full should be around 64V-67V
• For 72V bikes the voltage range when full should be around 77V-80V
• Lithium batteries have a similar but slightly different total cell voltage.
• If you want to do a voltage check you must own a multimeter and put it on the voltage
setting if the bike does not have a factory voltage display as a feature already.
Q. Is there a way to condition the batteries? How do I take care of my batteries?
• We suggest that brand new batteries should be charged fully then discharged fully for 3-5X
to condition the batteries for full range. It's best to keep your batteries power level stay
closer to the fully charged status rather than in a depleted status. Batteries won't perform
as well in really cold temperatures. We recommend charging wherever you go whether it is
at work or wherever you go if possible. Freezing your batteries will damage them. Over-
charging or leaving them in a state of discharge will also harm them. Battery set should
never charge more than 8-10 hours max.
Q. What should I set my tire pressure at?
• Typically, rear tires should be kept closer to 35-40psi for less rolling resistance although the
front tire bears less weight so it can be set at a bit lower, closer to 30-35psi.
