Brakes
The braking system installed on the product includes mechanical disc brakes that can be activated on the front wheel and on
the rear wheel via the respective levers located on the handlebars.
The brake lever on the right side of the handlebar activates the rear brake and stops the rear wheel whereas the brake lever
on the left side of the handlebar activates the front brake and stops the front wheel.
The front and rear brake levers must be positioned and adjusted so they are comfortable to use and favour the natural
position of the hand and fingers used to pull them, thus minimising the force and amount of time required to pull the brake
lever whilst ensuring that the brake is applied evenly.
Brake levers installed on the E, a version with an electric motor located in the rear hub with sensors and control
electronics that are not integrated in the central drive unit (see Elephant Pro), are individually equipped with a device (cut-
off sensor), which immediately electronically disconnects the drive action of the motor when the brake lever to which it is
connected is operated.
Check operation of the brakes with a low speed brake test (max 6km/h) in an obstacle-free zone.
As the brake pads on the callipers become worn and their thickness is reduced, the brake lever will have to be pulled further
to exert the same braking force.
To compensate for this type of wear, it will be necessary to act on the adjustment ring nut of the brake cable, located behind
the corresponding lever, to restore the optimal braking conditions; in the presence of excessive wear of the brake pads, a
replacement will be necessary.
Gear change and drive
The cable gear change system supplied with the product is indexed and allows you to change the gear ratio and pedal
stroke metrics by adjusting the control device on the handlebar, determining the sideways movement of the chain on the
corresponding sprocket of the cassette installed on the rear wheel via the derailleur.
Make sure the gear change and its adjustment are correct and that the chain and drive gears are clean and properly
lubricated.
Wheels and tyres
Check the correct centring, suitable tensioning of the spokes and correct installation and tightening of the pass-through pins
and/or the quick release mechanism of the front wheel (if present).
Check the presence and correct installation of the reflectors.
Check the condition and state of wear of the tyres: there must be no cuts, cracks, foreign bodies, abnormal swelling, visible
canvases and other damage.
Check the tyre pressure by referring to the specific range of minimum and maximum values shown on the side of the tyre
(suitable pressure must be customised according to the weight being carried, the weather conditions and road surface).
Properly inflated tyres, in addition to improving wheel slip, reduce the risk of punctures and deterioration.
