Opening the Box
The StreetStrider comes in a large box (Fig. 3-1a) with a set of holes for handles near the top, one on either side, to show
which side is up. Open the box with a sharp edge to cut the top flap. Notice how the two end flaps secure each end
of the folded StreetStrider inside (Figs. 3-1b). The front end beam has corner padding for protection. The two front wheels
are secured to the front head tube and the rear wheel is secured to the middle of the frame. A small box strapped to the
rear drop outs contains the tool kit, a packet of assembly screws, the bottle cage, and instructions for the operation of the
rear internal gear hub.

Unpacking the StreetStrider (con’t)
Lift the folded StreetStrider out of the box, close the box flaps, and set the unit on top of the box as shown (Fig. 3-2a).
IMPORTANT: Save the box and the packing material - it must be used to repack the StreetStrider for any returns. Remove the packing
material and ties to free the wheels from the frame (Fig. 3-2b) and lay out the contents of the small box, including the tools
(Fig. 3-2c).
TERMINOLOGY: The right and left sides of the StreetStrider refer to sides when one is striding.
Attaching the Two Front Wheels
The brake cables are attached to the front wheels. Rest each front wheel against the box (Fig. 3-3a). Remove the king
pin bolt from the left front beam clevis using fingers or, if tight, the 6 mm hex and 17 mm open end wrenches (Fig. 3-3b).
Slide the black steering knuckle attached to the left wheel into the clevis slot and insert the king pin bolt (Fig. 3-3c) and
tighten until snug with the 6 mm and 17 mm wrenches. IMPORTANT: Make sure the brake cables are routed over the front beam
and under the linkage rods (Fig. 3-5b). IMPORTANT: Make sure that the steering arm of the knuckle extends forward and that the king pin
bolt is not too tight to prevent the knuckle from swiveling on the king pin bolt.

To attach the left inboard rod end on the aluminum steering linkage to the head tube bracket, remove the nut from the rod
end stud (Fig. 3-4a), insert the nut into the slot on the back side of the bracket (Fig. 3-4b), push the rod end stud into the
hole to contact the nut, and screw the stud in tight using the 12 mm open end wrench (Fig. 3-4c). Repeat the procedure
to attach the right front wheel (Fig. 5-5a). When the front wheels are attached, the front end should appear as shown (Fig.
3-5b).
Unfolding the Head Tube
Now that the front wheels are installed, you are ready to unfold the head tube and fix it
upright. This will require the 2 cap screws (male, black with 6 mm hex head) and 2 barrel
nuts (female, silver with 5 mm hex head), located in the plastic bag found in the small box
(Fig. 3-6a) (the other screws in the bag are for the rear rack and the bottle cage). Insert
the barrel nuts into the left side of both bolt holes. Raise the head tube into the full upright
position (Fig. 3-6b,c). Insert the short cap screw in the front middle bolt hole and the long
cap screw in the rear top bolt hole of the joint (Fig. 3-6c). Using the 5 mm hex wrench for
the female side (left side) and the 6 mm hex wrench for the male side (right side), securely
tighten all three of the screws in the joint (Fig. 3-7).IMPORTANT: Keep the main frame rectangular
packing foam piece to use when folding for transportation or storage.

Positioning the Strider Poles
Upper strider poles can be moved up and down by up to 2” as indicated by the limit line, as well as rotated forward or
backward in the lower strider pole insert tube for rider size and preference. At the factory, the poles are set at the highest
position and rotated inward for packing. Use a 5 mm hex wrench to loosen 2 screws in each clamp at the base of each
strider pole (Fig. 3-8a),then make adjustments and tighten clamps. IMPORTANT: When finished adjusting strider poles, make sure the
upper right and left pole positions are mirror images (Fig. 3-8b). Strider poles can be readjusted after riding the StreetStrider to try
different positions.
When the strider poles are aligned, the hand brake lever and twist grip shifter positions can also be adjusted to suit the rider.
The brake lever clamp requires a 5 mm hex wrench and the right side twist grip shifter requires a 3 mm hex wrench for
adjustment (Fig. 3-8c). Once the brake levers are positioned, rotate the twist shifter so that the gear number is facing the rider,
then tighten.
If you own an ETX 3r, use the next section to install the rear wheel. If you own an ETX 8r, use the section following this one to install the
rear wheel.

Remove ties and packing material from the rear triangle (Fig. 3-9a) and from the chain (Fig. 3-9b).
Thread the shifter cable along the frame (Fig. 3-10a) and through the hanging loop of chain (Fig. 3-10b), and secure the cable
to the cable boss (Fig. 3-10c) with the black plastic cable clips located in the screw bag.
Unscrew the hub nuts on each side of the wheel so there is a ~1 cm section of axle thread showing (Fig. 3-11a) that will be
slid into the frame dropout slot. Open the rear brake with the quick release lever so the tire can slide between the brake
pads (Fig. 3-11b). With the wheel partly inside the frame, thread the chain around the hub sprocket (Fig. 3-11c).

Raise the rear wheel so the exposed axle slides into the frame dropout making sure the yellow non-turn washer on the left
side is outside the dropout (Fig. 3-12a). Pull the wheel rearward to make the chain taut and center the wheel, then tighten the
hub nuts using the 15 mm open end wrench (Fig. 3-12b). Insert the push rod, located in the screw bag, into the right side of
the rear axle (Fig. 3-12c).
Place the bell crank unit located on the end of the shifter cable (Fig. 3-13a) all the way onto the right axle (Fig. 3-13b) and
tighten the fixing screw using the 5 mm hex wrench (Fig. 3-13c). Finally, close the quick release rear brake and check that the
brake shoes contact the rear rim on the side face. Adjust if necessary.

Remove ties and packing to free the rear wheel. Remove all packing material from the rear part of the frame to free the
chain and shifter cable (Fig. 3-14a). Unscrew the hub nuts on each side of the wheel so there is a ~1 cm section of axle
thread showing (Fig. 3-14b) that will be slid into the frame dropout slot. Open the rear brake with the quick release lever so
the tire can slide between the brake pads (Fig. 3-14c).
With the wheel partly inside the frame, thread the chain around the hub sprocket (Fig. 3-15a). Slide the rear axle into the
dropouts so that the non-turn washers (black on right side and gray on left) are on the outer side of the frame just under the
chrome hub nuts. The non-turn washers have a tongue facing rearward that fits into the dropout slot (Fig. 3-15b) to prevent
turning. Pull the wheel rearward to make the chain taut and center the wheel, then tighten the hub nuts using the 15 mm
open end wrench (Fig. 3-15c).
Install the shifter cable by inserting a 2 mm hex wrench into the hole on the rear edge shifter cassette pulley at about the 9
o’clock position (Fig. 3-16a). Rotate the cassette pulley counter clockwise by moving the inserted 2 mm hex wrench to the 6
o’clock position (Fig. 3-16b). Insert the shifter cable fixing screw with the hex nut facing outward into the oblong slot on the
cassette pulley, now located at the 9 o’clock position (Fig. 3-16c).

While still holding the 2 mm hex wrench in the 6 o’clock position, insert the ending ferule of the shifter cable housing into
the cassette bracket that is facing forward in the 3 o’clock position (Fig. 3-17a). Slowly release the tension on the 2 mm hex
wrench to allow the return spring to move the hex wrench back to the 9 o’clock position, making sure the shifter cable lies
in the groove of the cassette pulley (Fig. 3-17b). Move the twist grip shifter to gear 4 and check the indicator window on the
cassette pulley to make sure the 2 yellow setting lines are together (Fig. 3-17c; see also Fig. 3-21 Adjusting the Rear Hub Shifting).
Rotating the Crank Arms
In order to fold the StreetStrider for packing and transporting, one crank arm needs to be rotated 180 degrees so both crank
arms are in the same position. Therefore in order to restore the crank arms to the correct position for riding, the left crank arm
has to be rotated 180 degrees relative to the right crank arm. To start, rotate the crank arms to point rearward. With the 8
mm hex wrench, unscrew the one key release crank bolt on the left crank arm (Fig. 3-18a). Lift the crank arm off the square
tapered bottom bracket spindle (Fig. 3-18b) and rotate it to the opposite position (Fig. 3-18c), then replace the left crank arm
onto the spindle. Screw the crank bolt back in with the 8 mm hex wrench (Fig. 3-18d), tightening to 350 inch/lbs (29 ft/lbs
or 39 N/m), to create a secure connection between the crank arm and the bottom bracket spindle.

IMPORTANT: For the needed leverage, use a 8 mm hex wrench or socket wrench with 8 mm hex bit with at least a 6 inch long handle. Also,
make sure that some grease is present on the square spindle to facilitate crank arm installation and removal when folding the ETX. The Park
Tool company provides torque specifications for screws, bolts, and nuts on bicycle parts http://www.parktool.com/repair/
readhowto.asp?id=88.
Aligning the Front Wheels
The front wheels need to be aligned so that they do not point in (toe in) or point out (toe out) – they need to be parallel to
each other. IMPORTANT: This adjustment may have been performed at the factory but it is good to periodically check front wheel alignment.
This alignment is important for performance so take the time to do it correctly. First, insure that the tires are inflated up to 80
psi. Next, locate the steering linkage rods that have a spherical rod end on each end (Fig. 3-19a). The inboard rod end
has left hand threads and the outboard rod end has right hand threads. Each rod end is screwed into the aluminum rod
and secured with jam nuts to secure adjustments (Fig. 3-19a). With a tape measure, measure the distance from the center
rib of one tire to the center rib of the other tire on the front leading edge (Fig. 3-19b) and on the rear trailing edge (Fig. 3-19c),
and compare the two measurements. The distance should be near 26 ¼ inches. If the measurements are not equal, use
the steering linkage rods (Fig. 3-19a) to make the tires parallel. To do so, hold onto the flats on the linkage rod with a 12 mm
wrench and use the other 12 mm or an adjustable wrench to loosen the nuts on either end of linkage rod, with left hand
thread inboard and right hand thread outboard. Then rotate the linkage rod one way or the other and note that the tire
angle changes and a parallel position is achieved. Make sure that any adjustment to the right linkage rod is duplicated
on the left linkage rod, maintaining symmetry. When the leading and trailing edge distances are equal, clamp the linkage
rod with the jam nuts so the rod does not move. Hold onto the linkage rod again with one 12 mm wrench and tighten the
inboard and outboard nuts snuggly using the other 12 mm wrench. Check the distances one more time to make sure they
are equal.

Checking Brake Function
Pump up the tires, then check that the brakes are functional. To check rear brake, stand over the StreetStrider facing forward,
squeeze right grip brake lever and push forward (Fig. 3-20a). If rear tire does not skid, unscrew the brake adjustor nut on
the right brake lever to make sure the rear rim is clamped by the rear caliper. To check the front brakes, stand in front of the
StreetStrider, facing it, and pull it towards you. Then squeeze the left grip brake lever, first lightly then harder (Fig. 3-20b). If
the vehicle stops moving without pulling to one side, then the front brakes are adjusted correctly. If one front wheel stops
before the other, it will pull to the side that stops first. To adjust the brake that is not stopping, unscrew the brake adjustor
screw that is located at the front of the black bracket of the drum brake shoe plate (Fig. 3-20c). Unscrew the adjustor screw
one turn and repeat stopping test again until the ETX stops without pulling to a side.
