Step 3: Tips & Tricks to Get the most from your MOD BIKES

Here are some Tips & Tricks to get even more out of your journey.

MOD Connect: The MOD City+ 3 offers wireless connectivity with the Lumos Ultra helmet, unlocking the helmet's turn signals and brake lights to enhance rider safety. You can find more information here: MOD Connect Feature

Tighten pedals: Be sure to tighten the pedals of your City+! These come on the bike, but it is imperative that they are tightened as they will strip the crank if they are loose.

Folding Pedals: To fold the pedals on your MOD City+, push them inward and they will fold up.

Headlights: Hold the + button for 2-3 seconds to turn your headlights and tail lights on and off.

Turn Battery On: The City+ battery has an on/ off switch on the battery. This needs to be flipped on to operate the bike.

Version Number: The version number of your bike can be found on the rear of your seat post. If your bike does not have a number, it is version 01 or 02.

Keys: DO NOT LOSE YOUR CITY+ KEYS! These keys cannot be replaced, and we do not have a master set. The lock and keys are unique to each City+.

Mounting Locations: The City+ has 2 built-in mounting locations specifically for Foldylock. You can mount Foldylock on the upper part of the frame or the lower. The water bottle will best mount to the stem using the Two Fish Water Bottle cage.

Error Code 25: Be sure not to hold the brakes when turning the bike on! This will activate Error code 25 on your display.

PSI: The proper PSI can be found on the side of your tire. This will let you know the correct pressure to inflate your tire to.

USB Port: There's a hidden USB port at the bottom of the display screen and will charge certain devices on your ride!

Serial Number: The serial number for your bike can be found at the bottom of the head tube.

Troubleshooting

Loose handlebars or stem → Tighten stem bolts securely using a torque wrench (typically 5–7 Nm) and confirm alignment with the front wheel.
Brakes rubbing or misaligned → Loosen the caliper bolts, squeeze the brake lever to center the caliper, then retighten bolts while holding the lever.
Pedals won’t thread in or feel stuck → Confirm you're installing the correct pedal on the correct side (L/R marked). Thread in by hand before tightening with a wrench.
Chain falls off or shifts poorly → Check derailleur alignment, limit screws, and chain routing. Adjust cable tension using the barrel adjuster if needed.
Crank or other bolts keep loosening → Remove the bolt, apply thread locker (like Loctite Blue), and re-tighten to spec.
