CHAPTER 1: SAFETY FIRST
Dynamic Bicycles are designed and assembled to meet the highest safety standards. Our bicycles meet or exceed all
Consumer Product Safety Commission (CPSC) Requirements for Bicycles as detailed in 16 C.F.R. Part 1512.
Bicycle safety depends greatly on the bicycle operator. Failure to follow these safeguards may result in damage to the
bicycle and/or cause personal injury.
FOR YOUR SAFETY...
Always wear a helmet. An unprotected head is highly susceptible to injury, even from the slightest contact,
but wearing a helmet that meets the Consumer Product Safety Commission (CPSC) or CE safety testing
standards may help prevent injury.
Make sure that both front and rear brakes are working appropriately. Always use front and rear brakes
simultaneously to stop. Do not use front brake only; using the front brake only increases the risk of being
thrown off the bicycle and injuring yourself when riding downhill or traveling at a high speed.
Make regular inspections of your bike. Check to ensure that all screws, nuts, bolts and hardware items (control
cables, cranks, forks, pedals, etc) are tightened. Check bicycle frame for any dents or fractures (cracks). Be
sure all reflectors are in place. Replace parts that show wear or damage.
Maintain appropriate tire pressure to avoid hazards due to difficulties in steering, braking or pedaling.
Do not carry heavy materials or goods. Never carry a passenger on a rear carrier or seated on handlebars, top
tube or any other part of the bike.

Avoid riding in heavy rain or snow conditions. Rainy and wet weather conditions require special caution to
ensure safety in turning, accelerating and stopping.
Always obey local traffic laws including all traffic signs. When sharing the road with cars, please use caution
and follow all generally accepted rules of the road.
Always use proper hand signals for turning and stopping.
When riding at night, use proper reflection on bicycle, wear bright or reflective clothing and use lights, if
possible, to increase visibility by motorists
Rider must be able to straddle bicycle with at least one-inch clearance above the top tube when standing.
Do not use the bicycle for stunt riding and/or jumping.
Do not use the bicycle for unintended use. Misuse of the bicycle or riding in conditions outside the intended
use of this bicycle can result in serious injury and will void all warranty claims. Intended use is defined as
riding on designated road surfaces, sidewalks, bike paths or approved bike trails in a smooth manner with
both wheels on the ground.
Never ride after consuming alcohol. Bicycle riding requires balance which is impaired if under the influence of
alcohol.
Eye protection and appropriate cycling clothes are recommended.

CHAPTER 2: GUIDE TO SAFE OPERATION
MAKE SURE YOUR BICYCLE FITS YOU PROPERLY
The On Bike Share model is made for adults 18 years and older, with a minimum height of 5’0” and a maximum height
of 6’5”.
BEFORE EACH RIDE
Check your helmet and adjust strap. Always wear a helmet when riding!
Check attachment of both wheels and ensure the wheels are straight and spin freely between the brake pads.
Check your tire inflation.
Check your brakes to be sure brake pads are properly aligned to wheel rim and not in need of replacement.
Also be sure brake lever is properly adjusted (see section above on brake adjustment).
Check (and adjust as necessary) the shifting mechanism.
Check your handlebars, stem and bike frame for signs of stress or fatigue. This includes cracks, dents,
deformation, or discoloration. If any part shows signs of damage or fatigue, replace the part before riding the
bicycle.
Check for loose screws, nuts and bolts and other parts, such as cranks, shifter, brakes and control cables.
Clean (and lubricate as necessary) all moving parts that are exposed to the elements such as the grip shift
lever, shift control cables, brakes control cables, pedals, and chain.

WARNING
Like any mechanical device, a bicycle and its components are subject to wear and stress. Different materials
and mechanisms wear or fatigue from stress at different rates and have different life cycles. If a component’s
life cycle is exceeded, the component can suddenly and catastrophically fail, causing serious injury or death
to the rider. Scratches, cracks, fraying and discoloration are signs of stress-caused fatigue and indicate that a
part is at the end of its useful life and needs to be replaced. While the materials and workmanship of your
bicycle or of individual components may be covered by a warranty for a specified period of time by the
manufacturer, this is no guarantee that the product will last the term of the warranty. Product life is often
related to the kind of riding you do and to the treatment to which you submit the bicycle. The bicycle’s
warranty is not meant to suggest that the bicycle cannot be broken or will last forever. It only means that the
bicycle is covered subject to the terms of the warranty.

HANDLEBAR COMPONENTS
The handlebar contains the components to control you bicycle, including steering, braking, shifting gears, and using
the bell to alert others around you of your presence.
OPERATING THE BRAKES
To use the brakes, with your hands on
the grips, use your fingers to squeeze
the brake lever inward towards the
grips. The lever on your right hand
controls the rear brakes; the lever on
your left hand controls the front
brakes. By squeezing the levers, you
actuate the brake arms on either side
of the wheel to squeeze on the rim to
stop the bicycle.
IMPORTANT: Use both brakes at the same time. Practice using the brakes in controlled conditions and at slow
speeds to familiarize yourself with the brake’s performance. The performance of the brakes are affected by speed,
rider weight, wet/slick/muddy road conditions, and the condition of brake pads and rim. Never apply the front brake
(left hand) only – this can cause the rider weight to shift forward and potentially force the rider over the handlebars.

Dynamic Bicycles Owners Manual

OPERATING THE GEARS
Shifting with internal gears is done using a single twist shifter
located on the right side of the bicycle handlebar. To change
gears, you twist the shifter forward and backward. The shifter
provides a gear indicator identifying the gear you are in at any
given time. The gear range on your bike may be from 3-speeds
to 7-speeds. When shifting gears, it’s always best to plan ahead.
You can shift gears at any time – while pedaling, coasting or
even at a complete stop. If you shift while pedaling, reduce
your pressure on the pedals. Excessive tension on gears
makes shifting difficult and accelerates the wear of the
components. Choose the gear most comfortable for riding
conditions. The objective of the gearing is to enable you to
maintain a constant rate of pedaling (and pedaling pressure)
regardless of the terrain.
Which gear should I be in?
The numerically lowest gear (1) is the easiest to pedal and is intended for climbing hills. The numerically largest gear
is for the greatest speed. Shifting from a “lower” gear (like 1) to a higher gear (like 2 or 3) is called an upshift. Shifting
from a higher gear (like 7) to a lower gear (like 6 or 5) is called a downshift. It is not necessary to shift gears in
sequence. From a stop, select the best “starting gear” for the conditions — a gear which is hard enough for quick
acceleration but easy enough to let you start pedaling without straining.

PRACTICE RIDING YOUR NEW BICYCLE
The features of your bicycle, particularly the rear hub gearing, operate differently than a derailleur system. These
features give you better comfort and control, but they also take practice before you can achieve proficiency. Practice at
slow speeds first. Before riding fast or in more difficult conditions, practice shifting and learn the function and
performance of your bike by riding where there are no obstacles, hazards or other traffic, until you’ve built up your
confidence. Gain comfort with the bike’s handling and responsiveness before riding on roads, trails or with automobile
traffic.
SHARING THE ROAD
Wear protective clothing including helmet, eye protection, and gloves. Always wear a helmet when riding!
When sharing the road with automobiles, ride defensively. To motorists, pedestrians, or other bicyclists, you
are not as visible as a car. Always watch for hazardous situations, and be ready to stop or take evasive action
at all times.
Use proper hand signals.
Ride single file when riding with other cyclists.
Ride on the correct side of the road; never go against traffic.
Do not ride ‘hands off’ the handlebars; road imperfections can cause the front wheel to turn unexpectedly.
Do not ride with loose objects attached to the handlebars, or any other part of the bicycle. They could get
caught in the wheel spokes, cause the handlebars to turn unexpectedly, or in other ways cause loss of control.
Do not carry a person. Standard bicycles are not designed to carry the additional load of a second rider. Also,
extra weight makes a bicycle much harder to balance, steer and stop.
Watch for, and avoid, potholes, drain grates, soft or low shoulders, and other deviations which could cause
your wheels to slip or create an impact. When crossing railroad tracks or drain grates, do so carefully at a 90°

angle. If you are not sure of riding surface conditions, walk your bike.
Watch the cars you are preparing to pass.
If a car suddenly enters your lane, or someone unexpectedly opens the door of a parked car, you could be
involved in a serious accident. Mount a horn or bell on your bicycle, or carry a whistle and use it to alert others
of your presence.
Be careful when riding in low light conditions. Use proper lighting where appropriate.
Your bicycle is equipped with a full set of reflectors; keep them clean and in position. As useful as these
reflectors are, they do not help you see, nor do they help you be seen unless light is directed on them. Use a
working headlight and tail light when you ride in poorly lighted or low visibility conditions.
Also wear light, bright, and reflective clothing, especially at night, to make yourself more visible. The important
thing is to see and be seen. If you do any amount of riding at dusk, at night, or in any poorly lighted conditions,
consult your local bicycle dealer to find appropriate products to aid your vision and make you more visible.
Understand the “Rules of the Road” in your area. In many states, bicycles are subject to the same traffic laws
as automobiles.

CHAPTER 3: ASSEMBLY INSTRUCTIONS
Your new bicycle is 90% factory assembled. If you are uncomfortable with the final assembly of your bicycle,
please contact a local bike shop for assistance. The final assembly of your bicycle includes:
Attach Handlebar
Attach Pedals
Attach Front Wheel
Attach Front fender
Attach Rear basket
You will need the following tools for assembly:
Cutting tool or knife (for unpacking bike)
15mm wrench or adjustable wrench
4mm, 5mm, 6mm Allen wrench (included with bike)
ATTACH HANDLEBAR
The handlebar is pre-assembled with brake levers, grips and shifting mechanism attached. All that is required is to
attach the handlebar to the bike on stem. When the handlebar is attached properly, the shifting mechanism will be on
the right hand side. Also be sure that the brake cables and shift mechanism cable are not twisted or wrapped around
stem or handlebar. All cables should extend forward from the bike in front of the handlebar.

For Bikes Using a Threaded (or Quill) Stem:
STEP 1: Insert the handlebars with stem into head tube of frame with
handlebars facing forward and all cables extending forward from
the bike as shown.
STEP 2: Set stem at desired height. Be sure stem is not extending out of
the head tube of the frame above the “Minimum Insertion Point”
marked on the side of the stem with a series of small vertical
lines.
STEP 3: Remove black rubber cover on the top center of stem (if present)
and use a 6mm Allen wrench to tighten the bolt in the top center
of stem while keeping the handlebar facing straight forward.
STEP 4: Replace black rubber cover over stem bolt (if included).
ATTACH PEDALS
Although the two pedals supplied with your bike look the same, they
are not. Bicycle pedals are threaded to match the left and right crank
arms of your bike. The pedals are labeled “L” and “R” on or near the end
of the spindle.
STEP 1: Insert the pedal marked “R” into the right crank arm and tighten
by turning the pedal axle clockwise.
STEP 2: Insert the pedal marked “L” in the left crank arm and tighten
by turning the pedal axle counter-clockwise.

ATTACH FRONT WHEEL
To be ridden safely, the front wheel of your bicycle must be firmly attached to
the front fork. The On Bike Share bicycle uses a solid axle with 15mm nuts to
secure to the fork dropouts. Insert the wheel into the dropouts to the axle sits
fully inside the dropouts at the bottom of the front fork. Tighten the axle nuts on
both sides of the wheel, holding the wheel straight between the fork.
ATTACH BRAKES
Attach brakes above front wheel using the rear wheel as a guide when
attached.

INFLATE TIRES
Inflating and maintaining proper tire pressure is critical to safe operation
and ensuring maximum efficiency and longevity of a tire’s use. Inflate
your tires to the air pressure recommended on the tire sidewalls (i.e. 50-
85 PSI). Tires offer a range of inflation. When inflating a tire, consider the
weight of the rider (and any load). Within the range, higher pressure
usually gives the best performance on hard surfaces like pavement, while
lower pressure works best for off-road riding. Use a tire gauge to check
tire pressure before each ride, as changes in air temperature and riding
conditions can affect tire pressure.

Tire Valves
There are primarily two kinds of bicycle tube valves: The Schraeder Valve and
the Presta Valve. The bicycle pump you use must have the fitting appropriate to
the valve stems on your bicycle.
The Schraeder valve is the same as the valve on a car tire. To inflate a
Schraeder valve tube, remove the valve cap and clamp the pump fitting onto the
end of the valve stem. To let air out of a Schraeder valve, depress the pin in the
end of the valve stem with the end of a key or other appropriate object.
The Presta valve has a narrower diameter and is only found on bicycle tires. To inflate a Presta valve tube using a
Presta headed bicycle pump, remove the valve cap; unscrew (counterclockwise) the valve stem lock nut; and push
down on the valve stem to free it up. Then push the pump head on to the valve head, and inflate. To inflate a Presta
valve with a Schraeder pump fitting, you’ll need a Presta adapter (available at your bike shop) which screws on to the
valve stem once you’ve freed up the valve. The adapter fits into the Schraeder pump fitting. Close the valve after
inflation. To let air out of a Presta valve, open up the valve stem lock nut and depress the valve stem.
NOTE: Patching a tube is an emergency repair. If you do not apply the patch correctly or apply several patches, the
tube can fail, resulting in possible tube failure, which could cause you to loose control and fall. Replace a
patched tube as soon as possible.

ATTACH ACCESSORIES
Rear Basket
Rear baskets come with the bike. Use the included bolts to secure the basket
to the rear of the frame using a T25 torx driver.
Front Fender
To add the front fenders to street bicycles:
STEP 1: Identify the fender and attachment hardware. With front wheel on
bike, position the fender in place and secure the top of the fender
to the arch of the front fork above the front wheel and secure the
fender to the bicycle.
STEP 2: Position the fender arms on each side of the wheel and attach the
end of the arms to the holes in the dropouts at the bottom of the
fork. Set desired position of fender and tighten all bolts.

CHAPTER 4: CARE AND MAINTENANCE
Although your bike is designed to require little maintenance, routine inspections, adjustments and lubrication should be
performed to ensure your safety and sustain peak performance of the bike.
ROUTINE MAINTENANCE
Routine inspections and adjustments are fast and easy, and should be performed before each ride. Below is a list of
items to check before each ride:
Check that your wheels are straight and spin freely between brake pads.
Check your tire inflation.
Check your brakes to be sure brake pads are properly aligned to wheel rim and not in need of replacement.
Also be sure brake lever is properly adjusted such that brakes properly stop the wheel when lever is squeezed
(see section below on brake adjustment).
Check (and adjust as necessary) the shifting mechanism.
Check attachment of both wheels.
Check your handlebars, stem and bike frame for signs of stress or fatigue. This includes cracks, dents,
deformation, or discoloration. If any part shows signs of damage or fatigue, replace the part before riding the
bicycle.
Check your suspension adjustment (if applicable).
Check for and tighten any loose bolts and other parts, such as cranks, shifter, brakes and control cables.
Clean (and lubricate as necessary) all moving parts that are exposed to the elements such as the grip shift

lever, shift control cables, brake control cables, cranks, pedals,
and chain.
Test and Adjust Brakes
Your bicycle is equipped with linear pull (V-brakes) on the front and rear
wheels. When the brake lever is in its fully extended position, wheel rims
should rotate freely between the brake pads without any rubbing. When
the brake lever is squeezed, the brakes should fully engage and stop the
wheel before the brake lever touches the handlebar. If the brake lever
touches the handlebar before the brakes fully engage, the brakes should
be adjusted.
NOTE: Brake cables will invariably stretch out over time, resulting in the
need to squeeze the lever further to operate the brakes.
Adjusting the brakes to compensate for this cable stretch can be
done easily, however it is recommended that the brake cables be
inspected and replaced periodically by a bike shop to ensure
optimum safety and performance.
Part A: Barrel Adjustment
As your brake cable stretches over time, you will need to squeeze the
brake lever farther to engage the brakes. To compensate for this,
brake levers come with a barrel adjuster to re-tension the brake cable.
This adjustment however does not center the brake pads. When

Dynamic Bicycles Owners Manual
© Copyright 2012 Page 20
applying the barrel adjustment, you may be required to re-center the
brakes, which is described in part B.
Step 1: For road bikes equipped with caliper brakes, the barrel adjuster is located on the caliper brake. Turn the
barrel counterclockwise to tighten cable. The brake pads should engage the rim when the lever is at least at
its half way point. Retighten the lock nut against the lever housing.
Step 2: To loosen the brakes, first loosen the lock nut on the barrel adjuster. Then turn the barrel towards you
(opposite the direction the tires turn when the bike is in motion). The brake pads should engage the rim when
the lever is at least at its half way point. Retighten the lock nut against the lever housing.
Part B: Centering the Brakes
On bikes equipped with linear pull brakes, centering the brakes is
done by tightening or loosening the rebound adjustment screws
located at the base of both brake arms. (Small Phillips head screw).
This screw can take both Philips and Flat head screw drivers. (See
figure).
Step 1: Looking at the brakes, observe which pad is closer to the rim.
It is also recommended to spin the wheel to determine which
side is always the closest (many wheels have a slight but
allowable “wobble” in the rim). The pad that is the closest to
the rim is the pad that needs to be moved away from the rim.
