Assembly & Packing |
Bohdi Bikes can provide a service of unassembly and packing for your bike. The charge is RMB50/bike.
TOOLS NECESSARY FOR ASSEMBLY:
· Phillips screw driver #2
· Open end wrenches: 8mm, 10mm, 15mm
· Allen keys: 4mm, 5mm, 6mm
ASSEMBLY :
1. Remove bike from carton. Remove components from carton. Cut white plastic ties. Remove wrapping material from bike.
2. Insert handle bar assembly (stem) into frame (at the headset). Align handlebars with front fork and tighten stem with 6mm Allen key. Loosen handlebar coupling with 5mm Allen key - align handlebar shifters at 45 degree down angle (from horizon when forks on ground), tighten handlebar coupling with even gap on top and bottom.
3. Place bar ends on end of handlebar and tighten at a 15 degree up angle (from horizon when forks on ground) with 5mm Allen key. Press black plastic caps into handlebar ends.
4. Hand screw pedals onto cranks (pedal ends are marked with "R" and "L" distinguishing right and left pedals). Tighten with 15mm open end wrench.
Note: The right-hand pedal will be screwed in COUNTER-CLOCK-WISE.
1. Insert quick release skewer into front tire. Release front brake (where metal elbow connects with brake lever - attached to front shocks). Place front tire onto shocks center tire - tighten quick release. Re-attach front brake (where elbow connects with brake lever). May be necessary to let out some brake cable to allow enough room to re-connect brakes. Use 5mm Allen key to make brake cable adjustment on brake lever (attached to front fork).
2. Loosen seat post assembly with 6mm Allen key and rotate top bracket 90 degrees. Place saddle on seat post and rotate top bracket over saddle rails. Tighten saddle so when seat post is inserted into frame saddle is horizontal.
3. Attach white/clear reflector to black metal bracket with 8mm open end wrench. Mount black metal bracket (now with reflector) to front fork with screw, washer and nut with screw driver and 10mm open end wrench (placing washer next to nut and against front fork stay). With 8mm wrench - attach red reflector to black plastic bracket. Insert black rubber strip inside black plastic bracket and slide assembly over seat post (from bottom up). Black rubber strip may need to be trimmed to 2/3 the length to allow this to slide onto seat post. Tighten with screw driver.
4. Inflate tires to 40~65 psi begin to explore the terra firma.
FINE TUNING:
1. Brakes
Check brake pads to see if they are parallel to rim. If not, loosen brake pads with 6mm Allen key adjust brake pad to be parallel with rim tighten brake pad.
Check to see brake arms pull away from rim equidistant. If not, increase or decrease pressure of brake arm spring by adjusting black screws located at black plastic collar where brake arm is attached to frame. Adjust these screws so both arms pull back same distance (when brakes are released).
Check to see there is approximately 3mm space between brake pad and rim (3mm on each side). For slight adjustment use fingers to loosen/tighten silver plastic screw located at brake lever on handlebars. For major adjustment, move cable by loosening nut on brake arm (attached to forks or frame) with 5mm Allen key - adjust cable and tighten.
2. Shifting/derailleurs/gears
(Chain should never be in both front and rear largest sprockets or both front and rear smallest sprockets as it will flex chain beyond its intended use.)
3. Front derailleur
If chain is rubbing/clicking - use fingers to adjust black nut at shifter (on handlebars). To allow front derailleur to travel further up or down use screw driver to adjust two silver set screws located on derailleur - set screw closest to frame for upper range of motion and set screw furthest away from frame for lower range of motion. For major adjustment, loosen black nut (between rear wheel and down tube) with a 5mm Allen key and adjust cable appropriately.
4. Rear derailleur
If chain skips use fingers to adjust black knob (at back of the rear derailleur) - turn until chain stops skipping. Another finger adjustment - also black in color (which accomplishes same thing) is located on shifter (on handlebar). For major adjustment, loosen black nut (located on rear derailleur) with 5mm Allen key and adjust cable appropriately.
5. Saddle
For comfort, saddle is best in horizontal position. To adjust saddle, loosen bracket with 6mm Allen key, adjust saddle and tighten.
In addition to tilt, saddle can also be moved forward to backward on saddle rails. To adjust saddle, loosen bracket with 6mm Allen key, slide saddle forward or backward and tighten.
6. Handlebars
Height of handlebar assembly can be adjusted by loosening stem with 6mm Allen key and raising stem and tightening. Be sure not to exceed minimum insertion as denoted on stem.
The angle of bar ends and shifters is adjustable with 5mm Allen key. Loosen coupling on stem and twist handle to comfortable position.
Brake Assembly & Trouble Shooting:
1. Loosen the bolts on the brake pads and turn them to line up with the rim.
2. Hold the brake arms so they are almost straight up and down, while pressing the brake pads against the rims and then tighten brake pads down (it would be easier if you had 3 or 4 hands to do this, but believe me, it is really possible with just 2). By doing this, you ensure the brake pad is tightened down flush (parallel) with the rim. You may note that it is possible to tighten the brake pads down incorrectly so they are not parallel to the rim (this is a bad thing).
3. Feed the cable through the aluminum and plastic tube (elbow) and the rubber part.
4. Feed the cable end through the nut (with hole inside) on the brake arm.
5. Hold both brake arms so they are about 3 mm away from the rim and tighten down the nut with the brake cable running through it.
6. Test the brakes.
IF - both brake pads are touching the rim before you squeeze the brakes
THEN - let out some of the brake cable at the brake arm
IF - one brake arm pulls away from the rim with more force than the other
THEN - take the aluminum and plastic tube out of the brake arm holder (which allows both brake arms to "relax" to the full open position
THEN - tighten/loosen the black screw on the side of the brake arm. Tightening will increase the amount of "pull away" force and vice versa. Careful not to strip the head of the screw as this is easy to do.
THEN - replace the aluminum and plastic tube to the brake arm holder and retest the brakes. If the same side still pulls away from the rim with more force, then repeat (increasing the amount of the adjustment).
IF - the brakes rub on the rim
THEN - see if the wheel is attached to the forks correctly. It is possible to attach the wheel "out of true" which would make it virtually impossible to adjust the brakes correctly.
THEN - adjust the brakes by tightening the finger screw at the brake handle lever. This plastic adjuster screw (when tightened) will increase the space between the brake pad and the rim. If the finger screw is all the way in - the alternative is to let out some brake cable at the brake arm.
Packing:
-Take apart the following parts: pedals, front wheel, quick release for front wheel, handle bar stem, saddle, bar ends and reflectors, put them in a small box.
-Turn the front fork backward
-The most important is to protect shifters and brake levers. It can be done by loosening the screws between bar stem and handle bar, rotate the handle bar and then tighten it again.
-Put the handle bar on the left size and front wheel on the right side. And let handle bar stem and left crank arm "hook" the spokes of front wheel. Make the front wheel touch the frame as close as possible.
-Use 6 pcs of plastic locking tie to fix the handle bar, front wheel and frame together.
-Put the small box and bike back into the box.
