BRAKES
1 -
Be sure that the brake pads are aligned with the curve of the rim and that they contact the rim surface flat and
evenly (Figure 13). The brake shoe angle and height can be adjusted by loosening the Hex bolt attaching the
brake shoe to the brake arm. Notice that the brake shoe can articulate a certain amount up and down and side to
side.
2 - Loosen the brake cable anchor at the brake arm held by an Hex bolt allowing the brake cable to freely glide
through its anchor (Figure 14).
3 - Squeeze the brake arms together until the brake shoes contact the rim surface. Be sure that the black release
lever at the brake arm anchor is in the down position. Pull the cable taught through its anchor and tighten the
cable anchor bolt (Figure 14).
4 -
Squeeze the brake lever hard several times to take the stretch out of the cable and make sure that it does not slip
through its anchor. If the cable tension is too tight to allow the wheel to spin freely, loosen the anchor bolt and
give the cable some slack. If the cable has too much slack and you cannot apply enough stopping force to the
rim, repeat procedure #3 to take the slack out of the cable.
Be sure that the brake arms are evenly spaced from the wheel and there is some clearance between the brake pads and the rim surface. If the brake pads are not evenly spaced from the wheel, you can
balance the spacing by gripping the brake assembly and rotating until it is centered with the wheel.
NOTE: We highly recommend taking your bike to a local bike shop and having your brakes set-up by a professional mechanic
REFLECTORS
1 - Attach the plastic brackets to the handlebar and seat post. (Figure 15 - Front).
Slide the reflectors onto the brackets (white in the front, red in the back). (Figure 16 - Rear).
2 -
3 - Attach the wheel reflectors onto the spokes of the wheels (If not already installed at the factory).
FLIP - FLOP REAR HUB - To switch between the fixed cog and the freewheel cog
1 -
Loosen the nut on the rear wheel chain tensioner until it is loose enough to swing out of the way of
the frame dropout.
2 -
Loosen the axle nuts.
3 - Push the wheel towards the front of the bike to loosen the chain and slip the chain o of the cog.
4 -
Remove the rear wheel, remove the axle nuts and washers, switch the chain tensioner to the oppo-
site side of the axle and replace the axle washers and nuts.
5 -
Flip the wheel around and place it back into the frame.
6 -
Replace the chain on the cog.
7 -
Pull the wheel back so the chain is taut and tighten the nut on the end of the chain tensioner to
adjust chain tension. Do not over tighten the chain. There should be approximately ¼" of chain
slack up and down when properly adjusted.
8 -
While holding the wheel centered in the frame, tighten the axle nuts a little at a time alternating
between each one until the axle nuts are tight holding the rear wheel securely in the frame.
BEFORE YOUR FIRST RIDE
We strongly recommend you take your bike to
a professional bike shop and have them check
your work and fine tune the bike to ensure
your bike is safe to ride.
SERIAL NUMBER
It is important that you locate and
record the serial number of your
bicycle in case of a recall or if the
bicycle is stolen. The serial number
can be found under the crank bottom
bracket stamped into the frame
(Figure 17).

TIRES
* Locate the tire manufacturer's recommended inflation pressure found on the tire sidewall (listed
as "PSI").
* Using a hand or floor pump with a gauge, begin to inflate the tire to half its recommended infla-
tion pressure and check to see that the tire is properly seated on the rim. Be sure to inspect both
sides of the tire for proper fit.
* If the tire is seated unevenly or bulges out along the rim, let some air out of the tire and reposi-
tion the tire by hand so that it sits evenly on the rim.
* Continue to inflate the tire to the manufacturer's recommended pressure.
* Do not exceed the recommended pressure as this will cause an unsafe condition potentially
causing the tire to unexpectedly explode.
* Do not use a compressed air device to inflate your tires as the rapid inflation of the tire can
cause it to blow o the rim.
* Tires and tubes are not warranted against damage caused by over-inflation or punctures from
road hazards.
