4. How to Use the Lockstand QuadStruts


Never leave passengers or pets on a parked bike unattended.

Engaging and Disengaging the Kickstand

The QuadStruts work in tandem with the GSD kickstand, so you will always engage both at the same time. This means the QuadStruts also stay engaged whenever the Atlas Lockstand kickstand is locked.

To engage the QuadStruts, hold the handlebar with both hands, and use your foot to push the Lockstand Extensions down. Pull the bike backwards (and over the Atlas Lockstand) until you feel resistance. Then, push the handlebar down until the Atlas Lockstand is locked into place.

To disengage the QuadStruts, disengage the kickstand as usual, pressing the remote unlock lever and pushing the bike forward.

Vertical Parking: Only When Disengaged

When not in use, the Lockstand QuadStruts do not interfere with vertical parking of the GSD. However, please remember to disengage the QuadStruts before parking your bike vertically.

Lockstand QuadStruts Max Load Limit

The max load limit of the Lockstand QuadStruts is 100 kg (220 lb). This includes the total weight of the bike, accessories, cargo, and passengers. When using the QuadStruts, do not exceed the limit.
