Standard eZee Kits include an LED battery indicator. Note that the ON/OFF switch
on the LED indicator is not wired up to anything. The Cycle Analyst upgrade
option provides more detailed information on your ebike dashboard and uses
the same connector.
If your Cycle Analyst was purchased as an upgrade option, the configuration
settings are correctly set; if your Cycle Analyst was purchased separately,
adjust your configuration settings according to the specifications section

Charging your battery
You can charge your battery any time, whether it is fully discharged or not. To
use your charger, make sure the 110/220V switch on the back of your charger
has been set correctly and then connect it to your wall outlet and battery. The
LED indicator light will show orange when charging and takes about 5 hours
for a full charge. When the charger has stopped charging it will show a green
light.
The charger must be already connected to the battery pack when it is turned
on in order to initiate a charge cycle. If the charger light is already green when
it is plugged into the battery, it will not turn orange and start charging.
Store your battery fully charged and with its switch off. A stored battery must
be charged once every 6 months because the battery self-discharges over
time. Allowing the battery to completely self-discharge causes permanent
damage.
Wet weather tip: If you have exposed connectors that do not need to be
unplugged,
prevent wet weather from corroding the contacts and reduces the
chance of them getting tugged apart while riding.
use silicone tape or heat shrink to wrap around the connections.
This will

Warranty
Warranty against manufacturing defects:
2 year warranty on eZee Kit motor and controller and 1 year warranty on eZee
Battery and Battery Bag
Range and Speed
Using the supplied lithium battery, the eZee kit will provide a typical assisted
range of 25 - 40 km. Under motor power only, the range is reduced to 15-20 km,
while with judicious use it can stretched out to more than 50 km.
The speed of the motor is such that it will easily maintain 32 km/hr on the flats
in the 26” wheel size. The 700c wheel size is slightly faster. The 20” eZee motor
has been wound for a higher RPM so that it will also achieve 32 kph.
If the eZee kit is powered from a 48V battery pack, then the top speed will be
increased by 30%, to just over 40 km/hr. Similarly, the speed can be reduced to
about 20 km/hr by using a 24V battery. It is also possible to limit the speed to
any particular value using the CycleAnalyst upgrade option.

FAQ
Q.How long will my battery last?
A.Your battery will maintain its capacity for about 500 cycles or two years of
regular ebike use.
Q. My bike has suspension forks, can I install a hub motor?
A. The eZee hub can be successfully installed on suspension forks but
adequately strong dropouts are required to withstand the forces on the axle
slot. Either thick plate aluminum or Chromoly dropouts are recommended.
Q. Should I install a torque arm?
A. Torque plates are available for those who would like one, but are not
required if your tightening assembly is properly installed.
Q. Why doesn’t my charger light ever turn orange?
A. Your battery is not charging if your charger light does not turn orange.
Check your connections and that the 110/220V switch on the back of your
charger is set correctly.
Q. I stored my battery when it was flat, and now it is not charging, can I fix it?
A. It may be possible to recharge the battery bypassing the BMS, provided the
cells have not been discharged below a critical voltage. The only way to know
this is by opening the battery by a qualified individual opening the battery up
and examining individual cell voltages.
Q. Which batteries can I use with my eZee hub motor kit?
A. Renaissance Bicycle Company eZee Kits will work with just about any 24,
36, 48V battery pack that can deliver 20Amps.
Q. I have twist grip gear shifters, or I am left handed, can I use another
throttle?
A. Yes, our line of thumb, half-twist, and left-handed throttles are compatible
with the eZee Kit.
Q. What is the pedal sensor option?
A. The pedal sensor disables the throttle when the rider is not pedaling and is
available as an optional accessory. This enables compliance with Pedelec
regulations in European and other jurisdictions.
