Quick answer

Lock your Jasion ebike through the frame, not just a wheel, using a high-security U-lock or chain around a fixed rack. Fill the lock's interior space as tightly as possible, capture at least one wheel, and remove loose accessories before you walk away.

What to carry before you leave

A lock only works if you actually bring it. For most Jasion riders, a U-lock plus a secondary cable or chain covers the frame, one wheel, and a rack without adding much weight. If you commute daily, leave the heavier chain at your destination rack and carry the U-lock on the frame.

  • U-lock: primary frame-to-rack connection
  • Chain or cable: secondary wheel and accessory capture
  • Removable lights, bags, and loose items: take them with you

Choose a rack that limits leverage

Thieves prefer racks where the bike sits far from the anchor or where the lock rests on the ground. Pick a rack that holds the frame close, keeps the lock off the pavement, and sits in a visible, well-lit spot. If the only rack is a sign post, check that the sign cannot be lifted off its base.

Step-by-step locking routine

  1. 1. Park at a fixed, visible anchor: Roll the bike to a rack or post that is bolted down and in open view. Avoid isolated spots where a thief can work without being seen. Checkpoint: the anchor should not lift, wobble, or slide.
  2. 2. Remove loose items first: Take lights, bags, and anything not bolted down with you. Empty any front or rear basket so nothing valuable is left behind. Checkpoint: if it can be unclipped or lifted off, it should leave with you.
  3. 3. Position the U-lock through the frame and rack: Pass the U-lock through the main frame triangle and around the fixed rack. Keep the lock body high and the shackle tight so a lever cannot be inserted. Checkpoint: the frame, not just a wheel, must be inside the lock.
  4. 4. Capture at least one wheel: Run a cable or chain from the U-lock through the front or rear wheel. If you use a quick-release wheel, this step is not optional. Checkpoint: both the frame and one wheel should resist a pull test.
  5. 5. Fill the lock's empty space: A lock with a large open gap invites a jack or pry bar. Choose the tightest anchor point that still lets you lock the frame and wheel. Checkpoint: if you can fit a fist through the gap, reposition the lock.
  6. 6. Do a final pull test: Tug the bike gently and check that the lock, rack, and wheels all stay put. Confirm the lock is not resting on the ground where it can be struck. Checkpoint: a short, firm pull should move nothing but the bike's suspension.
