2 Before each use
It is important you perform a quick check of your bike every time you use it, checks should
include the following, if you find any damage or problems do not use the bike until the
problem has been solved or you have had the faulty item checked by a bike mechanic or
your retailer.
2.1 Check tyres for any visible damage
2.2 Check tyre pressures
2.3 Check for any loose nuts bolts or fixings
2.4 Check brake functions
2.5 Check electronic functions
2.6 Check reflectors are in place and lights are working
2.7 Check your battery for any visible signs of damage
3 Battery care
3.1 Before you use the battery for the first time it is best to give it a full charge
for 12 hours. To fully condition your new battery, you should complete three
‘deep’ discharge and charge cycles. This is achieved by using the bike until the
battery is completely (or close to) drained and then fully charging your battery (this
can take up to 12 hours for the first few charges). After this “conditioning”
process you can then charge and discharge the battery as and when you require,
although we recommend keeping it topped up.
3.2 A lithium ion battery will slowly discharge over time as it sits in storage. If a
battery is allowed to fully discharge, this will stress the cells in the battery and
reduce the capacity and life of the battery. During normal riding, the Wisper
batteries have a battery management system (BMS) which switches off the
electrical system when the voltage drops to a certain point i.e. the battery is not
allowed to fully discharge and the cells are protected. However, the BMS will not
prevent a battery from slowly discharging as it sits in storage. Therefore, it is
important to ensure that your battery retains some charge over the winter months.
Unfortunately, it is also not ideal to put your battery in storage with 100% charge as
this can put some stress on the cells. The following actions are therefore
recommended for battery care:
 Store your battery with a partial charge, ideally 40-80%. While charging, you
can check the number of green lights on the battery indicator (with the key
