THIN has arrived! We’re so excited to see happy owners out riding their THINs, but first: let’s get it put together correctly!

If you are unfamiliar with bike assembly, it is strongly recommended that you take your THIN to a local bike shop for assistance.  Most shops will be able to assemble and make any necessary adjustments to your bike for a small fee.

If you are confident with doing the bike assembly on your own, please watch the following video as a guide for assembly of your SONDORS THIN>>

The following is a transcript of the video, to help guide assembly.

INCLUDED PARTS & TOOLS:

Box#1 = L&R pedals, included tools, reflectors & mounts, battery charger, (2)4mm allen bolts, (2) phillips head screws, aluminum ferrule, small black rubber button

Box #2=battery & battery lock keys

**Battery Notes**

• Do not interrupt the charging cycle until the battery is fully charged
• Always follow the correct battery connection sequence
• Do not exceed 8 hours charging time
• Do not store the battery connected to the battery charger
• Battery must be charged at least once every 3 months if it is not being used for extended periods of time
• Read & follow the additional instructions and cautions listed on the battery labels

STEM & FORK ALIGMENT

Loosen the (2) 4mm pinch bolts and 5mm cap bolt

Rotate the stem so it is aligned with fork (as shown in Video)

Re-tighten the 5 mm cap bolt and (2) 4mm pinch bolts

Repeat this procedure after the wheel and handlebars are installed to ensure proper alignment

Rotate both the stem and fork into the forward position

ATTACH HANDLEBAR & ALIGN CONTROLS

Remove the (4) 4mm bolts & faceplate

Rotate the handlebar assembly up into the stem

Be careful not to twist or kink the cables attached to the brake levels & throttle

Replace the faceplate & lightly tighten the (4) 4mm bolts

Double Check that the handle bar is L/R centered in the stem and the bar is rotated in the position that will be ideal for your riding comfort

Finish tightening down the Faceplate bolts

Loosen the 5 mm bolt on the bottom of the brake levers, rotate to the desired position and re-tighten

To adjust the throttle: loosen the throttles 2.5mm set crew, rotate unit to your preferred position and re-tighten

*Be careful not to over tighten as it can inhibit throttle operation & make sure the throttle operates freely & doesn’t bind on the grip

Loosen the 3mm bolts on the grip locks, rotate the grips into your preferred position & retighten

Insert rubber cap onto 5mm stem cap bolt

FRONT BRAKE CABLE ATTACHMENT

Loosen the cable clamp on the caliper arm using the 5mm allen wrench

Pull the brake cable up approx 9.5″ to provide slack to install the cable in the brake lever

Rotate the black ferrules to align their slots with the slot on brake’s forward edge

Pull brake lever in and swing the cable end basket out

Place cable in basket and move cable through the forward edge slot

Tighten black ferrules down to secure cable, being certain their slots no longer align with brake lever slot

Arrange and secure cables using the 3 black plastic clips that were attached to the bike cables during shipping

FRONT WHEEL ATTACHMENT

Remove the plastic foot from the axle dropouts in the front fork

Loosen the R&L side axle nuts until they are slightly beyond the outside ends of the axel

Pull the fishtailed washers up to the inside surface of the axle nuts

Making sure the brake disc is on the left side of the wheel (same side as brake caliper) carefully place the axle in the front fork dropouts

The kickstand can now be lowered to stabilize the bike

On both the L&R sides: Insert the tail of the washers into the hole above the axle dropout slot on the fork

With the washers in the locked position, hand-rotate both nuts clockwise until they contact w/ the fork sides

*Make sure your wheel is centered, relative to the front fork

Tighten the axle nuts using the 15mm end of the stamped tool or a 15mm wrench

*after tightening, check again to make sure your wheel is still centered in the forks

FRONT BRAKE ADJUSTMENT

Use the 5mm allen key to loosen the clamp bolt on the brake caliper arm

Remove slack from the cable by pulling the inner cable into the brake caliper arm

Place metal end of cable jacket in the receivers of the lever unit and the upper end of the brake unit

Rotate the caliper arm upward approx 1/2″, hold the cable tightly below the caliper arm while tightening 5mm bolt

Loosen the rear facing upper and lower caliper attachment bolts using the 5mm allen key

when loosened, the brake caliper unit can move L/R over the disc rotor

Pull the brake lever to align the loosened brake unit over the disc rotor

With the brake lever still pulled, tighten both 5mm caliper attachment bolts on the brake caliper mount

Check for brake alignment and re-adjust brake cable in the caliper arm if needed

Front brake cable can be tripped with heavy wire cutters and the aluminum ferrule can be crimped on end of the cable

PEDAL ATTACHMENT

This bike includes a R&L pedal, they are marked with a “R” and an “L” on the end of the threaded post

The pedal orientation refers to the riders LEFT and RIGHT as you sit on the bike

Start w/ left pedal: Slowly rotate the threaded post onto the left side crank counter clockwise

It should turn easily into the crank by hand when aligned correctly

Tighten the pedal with a 15mm open-ended wrench or the included multi-tool

Right Pedal: Slowly rotate the threaded post onto the right side crank clockwise

It should turn easily into the crank by hand when aligned correctly

Tighten the pedal with a 15mm open ended wrench or the included multi-tool

REFLECTOR ATTACHMENT

The wheel reflectors have a vertical spoke slot through the side where the clip attaches

Position the reflector in the wheel and align the spoke in the reflector slot

Carefully push the clear connector button into the hole
