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.
Headlight: Hold the + button for 2-3 seconds to turn your headlights and tail lights on and off.
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.
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.
Serial Number: The serial number for your bike can be found at the bottom of the head tube.
Speed Magnet: (V1 & V2 Models) Speed is measured by the magnet in the rear wheel spokes. Make sure the flat side of your magnet is completely facing the speed sensor.
Mounting Locations: The Berlin has built-in mounting locations for Foldylock and the water bottle holder. With the Step-Thru frame, you can use the straps that come with Foldylock to strap onto the seat post.
USB Port: There's a hidden USB port at the bottom of the display screen that will charge certain devices on your ride!
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.
