k. Using your brakes
Your G Plus Mariner 7 includes a high performance “Tool Free” adjusting Promax Disc Brake system. Promax’s top
of the line XL-102 levers were chosen for their ability to offer quick stopping power with slight pull effort. The levers
where matched to Promax’s latest disc brake system, the DSK-715 front and rear disc brakes. Your new G Plus
Mariner 7 stops quickly and accurately. Oversized 180mm stainless steel disc rotors were utilized for the front axle
for increased heat dissipation. When properly adjusted, the G Plus Mariner 7’s high performance disc brake system
offers tremendous stopping power but they must be properly adjusted. Prior to leaving the factory, the G Plus
Mariner 7 brakes were adjusted tight and properly tested. Due to cable stretching from new, your brakes may need
to be readjusted within a few weeks of riding. Please refer to Chapter 7 “Maintenance and Replacement”, section c
“Brake adjustments” to adjust your brakes for optimum performance.
When braking, both brake levers should be applied simultaneously. Your left brake lever manages your front brake
and your right brake lever manages your rear brake. You should first become accustomed with the stopping power
of each brake (front & rear). Test each brake separately in a controlled environment for their ability to stop the
bicycle. Front brakes when locked can cause the rear wheel to come off the ground and the rider can be thrown off
the. In emergency situations, apply pressure to each brake lever, shift your weight to the back of the bicycle and
only attempt to use full force on the front brakes when the bicycle is not stopping quickly enough. You should
always keep a safe distance according to speed between vehicles, pedestrians and other bicycle riders from
yourself.
WARNING:
Locking the front wheel during braking can cause the rear wheel to lift off the ground
and throw the rider off the bicycle. Both brake levers should be applied simultaneously. In an emergency
situation shift your weight to the back of the bicycle. Locking the front wheel can cause the rider to lose
control, be thrown and cause serious injury or death.
l. Pedaling
Pedaling your G Plus Mariner 7 is the same as pedaling a traditional bicycle. It is recommended you add pedaling
to the power of the bicycle to enhance the distance per charge. The G Plus Mariner 7 is a 7 speed bicycle and has
the ratio of a 44T front chain ring (sprocket) against a 11-28T rear cassette which is designed to offer an easy
pedaling pace at any speed from 1 MPH to 16 MPH. It is recommended on steep inclines; the rider utilizes the
throttle to assist in powering the bicycle up the incline but simultaneously drops the bicycle to a lower gear. If a
rider’s style of riding is throttle only with no pedaling, distance per charge will be decreased and upon a steep
incline, the rider is required to assist the motor by pedaling to power up the incline.
m. Shifting gears
The shifting of gears is required to change the ratio of the
rotation of pedaling to allow more or less torque and lower or
higher speeds according to one complete rotation of the crank
set. If requiring more torque, you will shift to a larger rear
sprocket for a higher rotation of pedaling to a lower speed of the
rear wheel. To switch to a larger rear sprocket, you will need to
shift to a lower gear. Gear 1 is the largest sprocket which is 28
Teeth and your lowest gear. One full crank rotation creates a
1.57 turn of the rear wheel. For higher speeds from less rotation
of the crankset on flat pathways, you will shift to a smaller rear
sprocket for a higher wheel rotation to a lower crankset speed.
To shift to a smaller sprocket, you will need to shift to a higher
gear. Gear 7 is the smallest sprocket with 11 Teeth and your
highest gear. One full crank rotation creates a 4 turn of the rear
wheel. Please review the photo below on shifting gears.
n. Watching for obstacles around you
Your new G Plus Mariner 7 travels at higher speeds than most riders are accustomed to when pedaling a traditional
bicycle. It is very important you are aware of your surroundings and obstacles which may appear near you. You
must watch the road surface you are traveling on which could allow for the tires to slip or cause a flat. Examples are
soft shoulders, rocks, pot holes, uneven paths, grates, construction sites and more. Due to the higher rate of speed
when riding under motor power versus pedaling, objects will advance in your path at a faster rate. Pay attention to
other riders in your area, automobiles, motorcycles, pedestrians, poles, intersections and road signs to name a few.
The G Plus Mariner 7 resembles a traditional bicycle and people whether walking, driving or standing may not
realize you are on a motor powered vehicle and misjudge your traveling speed.
WARNING:
Hitting a pot hole, soft shoulder or other road deviation may cause you to lose control,
be thrown and cause serious injury or death.
