Viribus Folding Adult Tricycle Troubleshooting

Unable to switch to the minimum or maximum gear position.

If you cannot switch to the maximum gear, use a Phillips screwdriver to rotate the screw on the right side of the derailleur ( H ) until the small cog on the derailleur aligns with the smallest gear on the flywheel. If you cannot switch to the minimum gear, use a Phillips screwdriver to rotate the screw on the left side of the derailleur ( L ) until the small cog on the derailleur aligns with the largest gear on the flywheel.

Q2 The brake is too loose and not effective 

While squeezing the brake lever, observe whether the brake cable at the caliper contracts. If the brake cable does not contract, check if the lever clamp is properly installed and whether the brake cable is fully seated in the slot, as shown in the figure. If the brake cable contracts when the lever is squeezed, hold the lever all the way down and observe whether the wheel can still rotate. If the wheel can still rotate even when the lever is fully squeezed, it indicates that the brake cable is too loose. Loosen the screw indicated by the arrow in the figure to the right, pull the brake cable tighter, and then tighten the screw. Repeat the above steps until the wheel does not turn when the lever is fully squeezed.

How to fold the bicycle?

1. Open the handle and pull its bolt out of its holding bracket.

2. Raise the locking pin.

Do this by supporting the base of the handle with the top of your palm while at the same time positioning your thumb over the frame. Pull straight up with your palm while pushing down with your thumb. You should hear the pin disengage, leaving the front of the tricycle free to adjust.

3. Pivot the front of the tricycle to the desired position. The hinge cannot lock into place while it is open, use a bike lock if necessary.
