NOTE: Understanding the operation of the MOBIA bicycle are essential elements of bicycling
safety, performance and comfort.
A. SADDLE POSITION
The height of the saddle can be adjusted to a riders preferred height by changing the length of the visible
seatpost inserted into the bicycle seat tube. To adjust the height, follow these steps referring to Images
1 & 2:
- Loosen the seatpost cam lever, by opening the lever in a clockwise direction
- Raise or lower the seat post inside the seat tube to the desired height
- Check to make sure the saddle is straight (fore/aft and aligned with the bike frame)
- Re-tighten the seat post cam lever when completed

Once the saddle is at the correct height, make
sure that the seat post does not project from
the frame beyond its “Minimum Insertion” or
“Maximum Extension” mark.
NOTE: The full force of the cam lever action is
needed to clamp the seat post securely. The
amount of clamping force of the cam lever is
controlled by the tension adjusting nut. Turning the
tension adjusting nut clockwise while keeping the
cam lever from rotating increases clamping force;
turning it counterclockwise while keeping the cam
lever from rotating reduces clamping force.
B. OPERATING THE BRAKES
MOBIA bikes will have one of two types of brakes; drum brakes or coaster brakes. Drum brakes operate
by using handlebar mounted levers while coaster brakes operate by pedaling the crank arms backwards.
1. How to operate a drum brake (handlebar mounted levers)
Brake levers are mounted on the right and left side of the handlebar to operate the front and rear drum
brakes. It’s important to your safety that you learn and remember which brake lever controls which
brake. MOBIA brakes are set up as follows; the right brake lever controls the rear brake and the left
brake lever controls the front brake.
2. How a coaster brake works (crank arm)
To operate a coaster brake on the MOBIA bike,
reverse the rotation of the pedal cranks (IMAGE
3). Start with the pedal cranks in a nearly horizontal
position, with the front pedal in about the 4 o’clock
position, and apply downward foot pressure on the
pedal that is to the rear. About 1/8 turn rotation will
activate the brake. The more downward pressure you
apply, the more braking force, up to the point where
the rear wheel stops rotating and begins to skid.
We suggest rider’s practice slowing and stopping
smoothly without locking up a wheel. To familiarize
yourself with MOBIA bike brakes, alternate the
brake force being applied to understand the
stopping distance of the bicycle.
C. SHIFTING GEARS
MOBIA bicycles are offered as a single speed or a multi-speed bicycle with an internal gear hub
drivetrain. MOBIA bikes always have shifters located on the right side of the handlebar. To operate the
MOBIA multi-speed bike follow the steps below.
1. Shifting multi-speed bicycles
Shifting a multi-speed drivetrain is simply a matter of rotating the shifter, forward or backward, to the
indicated position for the desired gear ratio. After moving the shifter to the gear position of your choice,
ease the pressure on the pedals for an instant to allow the hub to complete the shift.
2. Which gear should I be in?
All MOBIA bikes are equipped with gear indicators on the handlebar shifter. The numerically lowest gear
(1) is for the steepest hills while the numerically largest gear (3) is for the greatest speed.
D. COURTESY BELL
MOBIA bikes are equipped with a courtesy bell on the left side handlebar grip (reference IMAGES 4 & 5).
To operate the bell twist the bell in a forward or rearward direction to active the bell.
E. FRONT BASKETS
MOBIA bicycles are offered with front baskets which are speci cally designed for our bicycle geometry.
Each basket design has a sticker visible to the rider stating the maximum loading capacity. Extra care
should be given when loading the basket so small items do not fall through basket openings, large items
do not reduce vision, and loose items in the basket do not slide around affecting the steering control of the
bicycle.
NOTE: Never carry passengers, pets, or things that reduce your vision or control of the bicycle. Be
aware that riding and parking with a load in the front basket may make steering more dif cult and make
it easier for the bicycle to tip over.
