General Rules For Safe Riding

1. DO NOT ALLOW ANYONE TO STAND OR SIT ON THE CARGO PLATFORM OR ANY OF THE

QUADRIBENT CONNECTING PARTS OR TO RIDE ANYWHERE EXCEPT SITTING ON THE

SEAT.

2. Adults should supervise children at all times.

3. Always wear a CPSC approved helmet and some form of eye protection.

4. Always ride with a rear view mirror attached to your helmet or mounted to your vehicle.

5. Obey all traffic rules and regulations, signs and signals.

6. Ride on the side of the road, going in the same direction as the traffic.

7. Use proper hand signals when turning or stopping.

8. Be alert at all times, especially watch for cars pulling out into traffic and for opening doors.

9. Please read EZ-1 SX/EZ-CLASSIC Owner’s Manual for additional information regarding “EZ-1 Riding Tips”,

“Night Riding Tips”, “Wet Weather Riding Cautions”, “Fitting Your EZ-1” and “EZ-1 Riding Tips”.

General Rules For Riding Your EZ-1 SX/EZ-CLASSIC Quadribent

1. Inspect your EZ-1 SX/EZ-CLASSIC Quadribentbefore every ride. Make sure all nuts and bolts on the EZ-1

and accessory Quadribentframe are securely tightened. Check your brakes by applying them and pushing the

Quadribentforward and backward to make sure they are engaging properly. Check your tires for proper air

pressure as indicated on the sidewall of the tires. Make sure the quick release levers on the wheels and seat are

properly closed and secure. Make sure all of the Quadribentmounting hardware is properly installed. Check to

see that the quick release pins on the steering tie rod are properly inserted and locked. Stop vehicle and discontinue

riding if any mechanical problems arise, including but not limited to any sudden changes in: vehicle stability,

steering control, and / or pedaling difficulty.

2. Check and adjust your seat position/seat recline before mounting your Quadribent. Never attempt to readjust the

seat position while vehicle is in motion.

3. Always ride your Quadribentwith a partner. Never ride the Quadribent“solo” for the vehicle may lose

stability in turns and can tip over resulting in serious injury.

4. Always wear the factory supplied seat belts when riding the EZ-1 Quadribent.

5. The Co-Captain Steering links the handlebars of both EZ-1 recumbents together allowing either rider to pilot the

Quadribent. Each rider should always keep both hands on the handlebars when the vehicle is in motion. Each

rider is responsible for steering around people, vehicles and/or any obstructions to avoid collisions with any objects

in your path.

6. Remove the factory supplied “parking brake” strap after mounting the vehicle and properly securing your seatbelt.

Always reinstall the “parking brake” strap before exiting the vehicle.

7. As a courtesy to your riding partner and for the safe operation of the Quadribentboth riders should communicate

all non emergency turns, braking, starts and stops before they are executed.

8. For the safety of both riders, it is recommended the vehicle be slowed to less than 10 miles per hour (mph) before

initiating any turns of 90 or more degrees.

9. The EZ-1 Quadribentis designed for use on streets and bike paths only. Off-road, off-trail, mountain trail and /

or open field riding is not recommended and should not be attempted.

10. Do not modify, drill holes or mount accessories to Quadribentcross beams or frame.

The Quadribentis 2-seat, side-by-

side, human powered vehicle that enables almost anyone to enjoy cycling.

The 4-wheeled design maximizes stability and the recumbent position maximizes your seating comfort. Heads-

up design eliminates neck, shoulder and hand pain. Co-

Captain steering allows either rider to pilot the vehicle

and the dual-

drive allows people with different physical abilities to ride together with either rider generating from

0 to 100 percent of the power. The Quadribenti

s great for combining an adult rider with a child and/or

physically challenged rider. The Quadribent

can be separated into two recumbent bikes for “solo” riding and

easy transportation however it is not recommended to be done on a regular basis. Most people never separate it.

ASSEMBLY INSTRUCTIONS WITH PICTURES

FINGER TIGHTEN ALL NUTS/BOLTS OF

AN ASSEMBLED PART THEN TIGHTEN

NUTS/BOLTS EVENLY.

REAR AXLE BRACKET INSTALLATION

1) Find angle brackets - install on left side of right

hand bike and on right side of left hand bike as

shown in Figure 1. Install to bike dropout bracket

with 5mm screws and rear wheel axle pin (lever

handle on the outside).

Figure 1

Caution – on left hand bike add washers as

required so that screws go through dropout but

don’t extend too far to interfere with chain in the

smallest sprocket.

2) Find front beam, large ‘U’ shaped 1 x 1

aluminum square tube. Remove two outboard

bolts/spacers on right side and attach to top tube of

right bike frame just behind the head tube. Install

spacers/bolts/nuts and tighten evenly, enough to

hold in place. See figure 2.

Figure 2

3) Find lower beam, 1 x 1 x 30” square aluminum

beam and steel bracket with rubber pad. Install to

both bikes with ¼-20 bolt as shown in figure 3.

Rubber pad on beam goes between cable housing.

Don’t tighten until everything is installed.

Figure 3

4) Find the rear beam assembly. 1 x 1 x 29”

square aluminum tube with attached plates.

Remove two of the ¼” x 1¾” bolts from each of

the plates and install the assembly on the rear of

the bike frame top tube. Reinstall two ¼” x 1¾”

bolts through plate/spacer/plate (tighten enough to

hold in place) as shown in figure 4.

Figure 4

E Z - 1 Q U A D R I B E N T A S S E M B L Y A N D U S E R G U I D E

CARGO PLATFORM INSTALLATION

5) Find the cargo platform (18 x 30” aluminum

sheet). With the three flanges up and the flange

down at the rear, slide the platform over the rear

axle angle brackets forward to the lower beam.

Install two ¼” x 1 ¾” bolts through the

platform/lower beam at the front and two ¼” x 1”

bolts through the platform/rear axle angle

brackets. Install two ¼” x 1 ¾” bolts through the

platform/vertical beam as shown in figure 5. If

all bolts can’t be installed, as a last resort, you can

‘chase’ the hole with a ¼” drill.

If you are connecting 2 EZ-CLASSIC models or 1

EZ-1 SX and 1 EZ-CLASSIC add the tapered

shim between the angle bracket and the platform

as shown in figure 5A.

Figure 5

Figure 5A

6) It is time to tighten bolts in the following order:

Front beam

Rear Top beams

Cargo platform

STEERING ASSEMBLY

7) Find steering levers and attach to handle bar

stem, about the same distance (on both bikes) up

from the head tube, with two 8mm x 45mm

machine screws & washers as shown in figure 12.

The steering lever should be outboard - right side

of right bike and left side of left bike (shown). The

levers should be rotated about 15°outboard in

relation to the front tire, but should be the same on

each side. Tighten both 8mm screws evenly,

enough to hold in place.

Figure 7

8) Find steering tie rod assembly (should measure

30” center to center) and attach to steering levers

using 5/16” x 2” bolts, plastic washer to go

between the steering arm and the rod end bearing

see figure 8.

Figure 8

9) Find and install orange Velcro parking brake on

either of the ‘drivers’ brake levers as shown in

figure 10. The parking brake is intended to keep

the Quadribent from rolling on relatively flat

ground, when not in use. Never park facing

uphill or down hill.

Figure 9

FRONT END WHEEL ALIGNMENT

10) Check front-end wheel alignment by

measuring the distance between the front rims of

the two bikes as shown in figures 10, 11 & 12.

Two measurements are required. The first is at

axle height on the leading edge of the front rims.

The second is at axle height on the trailing edge of

the front rims. These measurements should be

approximately equal. A difference of up to a 1/16”

is acceptable if the leading edge measurement is

smaller than the trailing edge. This is commonly

called “toe-in”.

Figure 10

Figure 11

Figure 12

13) If the two measurements show the front wheels

are out of alignment, loosen the two Allen screws

of the steering lever and rotate it as needed. After

adjusting the steering levers retighten the screws

and visually check that they are about the same

angle outboard, with the two front wheels straight.

Wheel alignment should be checked regularly,

before/after a long ride, after riding on rough

roads.

14) Please check all nuts and bolts to ensure they

are fastened properly.

When all hardware is tight and secure, mount the

seats to both bikes per the EZ-1 owner’s manual.

Check proper operation of the brakes, front and

rear shifters after Quadribent is fully assembled.

Test ride to verify adjustments.

DO NOT ALLOW ANYONE TO STAND OR

SIT ON ANY OF THE QUADRIBENT

CONNECTING PARTS OR TO RIDE

ANYWHERE EXCEPT ON THE SEAT.

E Z - 1 Q U A D R I B E N T A S S E M B L Y A N D U S E R G U I D E

15) The final assembly step is the installation of

the seatbelts. Unclip or open the lower two seat

back mounting clips from the EZ-1 koolback seat.

Thread the end of the seatbelt through the tri-glide

fastener and then around the exposed seat frame as

shown in figure 15.

Figure 15

16) Insert the end of nylon strap back through the

tri-glide as shown in figure 16.

Figure 16

17) Insert the end of nylon strap back through the

tri-glide as shown in figure 17. Reconnect the

middle two seat back mounting buckles on the EZ-

1 seat. Repeat this process on both the right and

left side of each seat on each bike.

Figure 17

18) Install the other end of the nylon straps through

the buckle as shown in figure 18. The buckle is

equipped with a quick release. Simply squeeze the

center of the buckle and it will open. Seat belt

length is adjustable by pulling on the ends of the

nylon straps. If the strap end becomes frayed it

can be sealed with a flame from a candle.

Figure 18

SPECIAL NEEDS CUSTOMIZATION

A second seat belt, at chest height, can be added to better secure “Special needs” kids and adults. Toe clips

and straps can be added to the pedals to secure feet to the pedals. Also extra straps can be added to the pedals

to go around the heel. Call Blackbird Designs for the latest developments in accessories for people with

“special needs”.
