  2. Release

    Enter your 6-digit account number and 4-digit PIN into the keypad on the back of the bike to unlock it.

  3. Ride

    Remove the U-lock and place it in the holster before you take off. To make a quick stop, press the “HOLD” button and lock the bike to a rack.

ride safe, follow the rules

Do a Pre-Ride Check

Check the bike’s tire pressure, try the grip bell, and if you’re riding at night check that the front and rear lights are illuminated.

Follow the Rules

Yield to pedestrians. Stop at all red lights and stop signs. Ride in the direction of traffic. Use the grip bell to signal your presence. Do not wear more than one earphone while riding.

Tips for Turns

Use hand signals to let drivers and other cyclists know your intention to turn or to stop. Don’t turn or change lanes without knowing the position of the cars and bikes around you.

Be Predictable

Make it easy for the other traffic around you. Don’t make unexpected turns that put yourself and others in danger. Ride at a steady pace so other vehicles can anticipate your movement.

Wear a Helmet

Wear a helmet whenever you ride. Always buckle the strap. Replace your helmet after any crash and whenever you see signs of damage. Avoid these common helmet mistakes
