- Never leave passengers or pets on a parked bike unattended.
Before Riding
- Using and riding a heavily-loaded GSD is quite different than riding without any additional weight. To become familiar with riding with a load, gradually add heavier items to the bike. Then ride in a safe location to get a feel how to balance with the additional weight.
- Check that both tires have a pressure between 40-55 psi.
- Check to ensure accessories have been correctly installed and securely fastened.

- Then push the handlebar downwards until the Altas Lockstand is locked.
- Ensure the Atlas Lockstand is locked before removing your hands.
To Disengage the Lockstand QuadStruts
- Hold the handlebar with both hands, press the remote unlock lever and push the bike forward.
