When you create a new bike — your first one, or another bike added later — your existing sessions don't auto-attach to it. LapBrain on purpose never guesses which sessions belonged to which bike. The bulk-assign panel lets you tell it explicitly without opening each session individually.

When you'd use this

  • You just signed up, uploaded a season's worth of sessions, then created your first bike.
  • You added a second bike (e.g. a track-only race bike alongside a street/track bike) and want to backfill which past sessions were on which.
  • You imported sessions from another tool or another rider's account and they all came in unassigned.

How to bulk-assign

  1. Open the menu in the top-right corner and choose Bikes under the Garage section. (You can also reach it via Settings → My Bikes — same surface.)
  2. Find the bike row you want to attach sessions to and click Assign Sessions.
  3. The panel expands with one row per loaded Ready + unassigned session. Each row shows the track name, the recorded date, the lap count, and the detected bike class (so you can sanity-check class fit before you click).
  4. Pick the sessions you rode on this bike using the row checkboxes, or use Select all to tick every loaded row.
  5. Click Assign N selected to commit the picks.

If you want to attach every loaded unassigned session to this bike with one click, use Assign all N instead — but that path requires an explicit confirm so you don't accidentally assign sessions from the wrong bike. Per-row checkboxes already count as confirmation, so Assign N selected is single-click.

What gets included

The panel only lists sessions where:

  • The state is Ready — sessions that are still processing (or errored) won't appear, because their analysis isn't yet stable enough to take an assignment.
  • The assignment kind is Unassigned — sessions you've explicitly labeled as Loaner (rented bike, paddock loaner, demo) stay outside the bulk panel. Loaner is a deliberate label, and the bulk panel won't silently overwrite it. To bulk-assign a Loaner session, change its label first via the per-session affordance.

Already-assigned sessions are also excluded from this v1 surface. To reassign a session that's already attached to a different bike, use the per-session affordance on the debrief view.

note

The panel scopes to sessions you can already see in your dashboard. If you want to bulk-assign older sessions, scroll the dashboard to load them first, then open the panel — it picks up new sessions live.

What happens after you assign

Each newly-assigned session goes back through the enrichment pipeline so its per-bike rollups (PBs, trends, coaching threads) include the new attachment. You'll see the affected sessions briefly show a "Processing…" state on the dashboard, then settle back to Ready with bike-aware analysis.

If you assign a session whose detected class doesn't match the bike's declared class, LapBrain doesn't refuse the assignment — but a non-blocking warning will appear after repeated mismatches on the same bike, so you can decide whether to update the bike's declared class or leave the assignment as-is.

What it doesn't do

  • It does not bulk-create or auto-pick a default bike. Identity is always rider-authored.
  • It does not assign Loaner sessions or already-assigned sessions.
  • It does not force you to assign anything — leaving sessions unassigned is a fully supported posture, and the class-scoped degraded analysis still works.
