ADDITIONAL NOTES ON THE INSTALLATION
VIBRATION
The motor and components can at times be under quite a lot of load which can result in
mild vibrations when accelerating or going up an incline. If there is a loose nut or bolt
anywhere on the bike, quite often that can increase the moderate motor vibration into an
almighty drone of a vibration, giving the rider the impression that the bike is about to come
apart. If this happens to you, you have to look for anything that could be loose. If there’s
something wrong with a component on the kit (like a motor) it won’t be that subtle
Note:-These kits are designed to be installed at home without any special tools or
expertise. However, in some cases, certain bike models require additional knowledge and
skill. You may contact us anytime if you need any guidance or assistance.

MAINTENNANCE
Just like any regular bicycle, your electric bike is going to need routine maintenance.
However, don’t be put off by the bike’s electrical components as they actually don't require
any maintenance – it’s the tires, the brakes, and the wheels that need to be maintained by
an Experienced Bike or E-Bike Mechanic.
Geekay Dealerships will ensure that before you buy, your bike is in tip-top shape from the
moment you take it out of the store. This is especially important for E bikes as they need
to be set up correctly to function properly. To get the longest life possible out of your
E-bike you can take some simple steps to maintain it yourself or you can take it to an
experienced dealer.
KEEP YOUR E-BIKE CLEAN IF POSSIBLE
Ideally, clean your ebike after each ride, especially after riding it through mud or dirt. You
should use a sponge with bike specific cleaners to gently wipe the parts down. Do not use
a hose or any kind of pressure washing as this can wash out grease lubricating the
bearings. It will also force water into the internal components which in turn will corrode
and destroy the electric parts.
KEEP THE TIRES PROPERLY INFLATED
It’s important to check your tire pressure at least once a week. You can use a tire pressure
gauge or the manual method of pushing down on the tire with your thumb. If the tire is
underinflated, it can lead to uneven tire wear and burn the battery too quickly. It will also
make your life easier as the bike will be easier and more fun to handle with less resistance.
Of course, you want to ensure that you don’t over inflate your tires as they will pop/ burst.
Be sure to check the correct pressure which is usually printed on the side of the tire.
CHECK THE BRAKE PADS
Keep an eye on the brake pads about once a month to see how much worn they are. If you
realize there is a lot of wear and tear then it is probably time to replace them. When you
start to ride, you always want to test out e-bike brakes to make sure they are in good
working order, especially if you haven’t ridden for a while. It’s essential that you have
effective brakes or else you could end up in a serious accident. Brake pads can be easy
and cheap to replace whenever needed so you don’t need to worry about spending money.

connected properly to the
controller.
Ask your dealer to fit another
motor and test the speed.
Low battery capacity
Battery overloaded
Hall wires loose
Damage to motor
