ASSEMBLY INSTRUCTIONS
Please read this manual carefully prior to performing the simple finishing assembly and prior to riding. We recommend
that a qualified bicycle mechanic assemble any cycle. Carefully remove the bicycle from the carton. You will notice the
bicycle is mostly pre-assembled at the factory.
TO ATTACH FRONT FORK/WHEEL ASSEMBLY TO THE FRAME:
Headset Assembly:
1) Grease headset cups (48) with Rustolene 200 (light grease) or equal. Bearings (49) are pre-greased at the
factory, but it is wise to add lubrication before assembly.
2) Place one headset bearing (49) onto fork steerer tube with balls facing up. Slide steerer tube into frame.
3) Place the other bearing on top of fork tube with balls facing down towards the cup (#48), which is already
pressed onto the frame.
4) Install top-adjusting cone (52) onto treaded fork steering tube. Hand-tighten, making sure bearings do not
bind. Turn back ¼ turn.
5) Install fork key washer (53) and reflector bracket on top of the adjusting cone with tip of washer in slot on
steering tube.
6) Install head lock nut (54) and securely tighten. Make sure that the fork rotates freely without being loose.
Excess play or resistance must be adjusted. Failure to adjust properly can lead to improper steering
response.
7) Install handlebar stem (55A) into the fork steering tube with the handlebar clamp facing forward. The stem must be
inserted far enough to reach the minimum insertion line. Tighten the stem bolt slightly at this point. Loosen the handlebar
clamp nut and slide the handlebar through the clamp, centering the knurled center section of the handlebar into the clamp.
8) Position the handlebar to the desired angle and tighten clamp securely. Recommended torque is 300 IN. LBS. Adjust
the handlebar rotation so that it is straight with the front wheel. Tighten stem bolt securely. Recommended torque 240 IN.
LBS. Be sure not to over tighten, as damage to the parts may occur causing steering failure.
9) If a drum brake was ordered, attach brake lever to handlebar Make sure brake cable is not tangled in any way.
INSTALLING PEDALS AND KICKSTAND:
1)Install kickstand.
2)Pedals are marked on the shaft with either an “L” or “R” denoting left or
right. The “R” pedal fits on the right (sprocket side) of the crank arm.
Tighten clockwise. The “L” pedal fits on the left side of the crank arm.
Tighten counter-clockwise (left-hand thread). Securely tighten.
Recommended torque 275 IN. LBS. CAUTION: Tightening in the wrong
direction will damage the crank threads, and will not be covered under
warranty.
SEAT ADJUSTMENTS:
Adjust the seat height to your desired level by loosening the seat clamp nut at the top of the frame’s seat tube. Re-tighten
at desired height. Make sure a minimum of 3 1/2” of the post remains in the frame tube. Never adjust post above this
level. Adjust angle of seat with nose raised slightly. Tighten seat clamp securely. (240 IN. LBS.)
MAINTENANCE TIPS:
Always inspect your Worksman Cycle to ensure that all nuts, bolts, screws and hardware are tight and that no parts are worn or damaged. Do not
attempt to straighten bent forks or frames.
Chain:
Lubricate chain once a month or as needed with light oil. Replace sprockets when teeth become worn,
bent or broken. Keep chain adjusted so there is no more than 3/8” slack. Note that we make the chains
tight at the factory, as we do know they will stretch during the break-in period. Lubricate crank parts
every six months. Replace pedals when the surface is worn or if axle becomes “tight” or frozen.
Drum Brake:
Some Worksman bicycles are equipped with a front drum brake. It is engaged by squeezing the hand lever on the
handlebar. To use “Park” feature, when cycle is completely stopped, squeeze hand lever and push in parking plunger
button on lever. To disengage, simply squeeze lever until parking plunger button releases. Drum brakes are pre-adjusted
at the factory. Readjust the cable tension as necessary using the adjusting barrel so that wheel spins freely and stops
when brake is applied. Always replace worn brake cables and damaged hand levers.
Coaster Brake (if applicable):
Foot activated coaster brakes are easy to use and reliable. To activate this internal brake, reverse the pedaling motion
until the brake engages. To avoid skidding and maintain control, apply care when braking. This is especially true on wet
surfaces. Apply brakes gently, gradually increasing pressure. Replace coaster brakes when they become worn. Check
chain tension regularly. Coaster brake hubs may make a vibrating noise under braking until they are broken in.
Tires:
Always check for wear or damage. We recommend 40PSI as proper level of inflation. Replace worn or cut tires and leaking tubes immediately.
