Mudguard Installation

Short answer

To replace the rear mudguard with the rear light version, remove the damaged mudguard, cut the lamp cable while leaving at least 20 cm from the frame, mount the new mudguard, reinstall the rear light, connect and insulate the cables, then test the rear light before riding.

Applies to

This guide applies to the Booda Bike Possible mudguard set — rear light version.

TODO: Confirm exact compatible Booda Bike models and production years.

Tools needed

Torx key T25
Torx key T10
Scissors
Wire stripping pliers
Heat-shrink tubing
Soldering equipment
Drill, only if the mudguard hole does not align correctly

TODO: Confirm required drill bit size.

Steps

1. Remove the damaged mudguard

The rear mudguard is attached at four points:

two mudguard stay attachment points
one bottom attachment point
one middle attachment point

Steps:

Unscrew the attachment points with a T25 Torx key.
After the screws are removed, the mudguard will still be connected by the rear light cable.
Cut the lamp cable.
Leave at least 20 cm of cable extending from the frame.

2. Position the new mudguard

Place the new mudguard onto the frame using only the bottom mount.
Check whether the mounting hole aligns correctly.
If the hole does not align, adjust the hole position with a drill.

3. Mount the rear light

Remove the rear light from the damaged mudguard with a T10 Torx key.
Install the rear light onto the new mudguard.
Route the lamp cable through the cable guard toward the end of the mudguard.
If the cable does not reach the end of the mudguard, remove only the necessary amount of cable guard so the cable can be accessed easily.

4. Mount the new mudguard onto the bike

Mount the mudguard onto the bicycle.
Secure the bottom mount, middle mount, and mudguard stays.
Check that the mudguard sits correctly over the wheel.
Check that the mudguard does not rub the tire.

TODO: Confirm torque values for the rear mudguard mounting bolts.

5. Connect the rear light cables

Find the point where the frame cable and rear light cable meet.
Slide heat-shrink tubing onto one side of the cable before connecting the wires.
Connect the lamp cables as shown in the original wiring diagram.
Make sure the red and blue wire connections do not touch each other.
Cut the red and blue wires so the connection points are offset from each other.
Solder the connections.
Pull the heat-shrink tubing over the connected cables.
Shrink the tubing.
Insulate the cables thoroughly.

6. Test the rear light

Turn on the front light.
Check whether the rear light turns on.
If the rear light turns on, the electrical connection is complete.
If the rear light does not turn on, do not ride in low-light conditions until the issue is fixed.

TODO: Add troubleshooting steps for rear light not turning on.

7. Final safety check

Before riding, check that:

the mudguard is secure
the rear light is secure
the rear wheel is correctly installed
the mudguard does not rub the tire
no cable can touch the tire, spokes, brake rotor, or belt drive
the rear light turns on when the front light is switched on

Spin the rear wheel by hand before riding. If anything rubs, moves, or feels loose, do not ride the bike.
