Mount the Classic and verify stationary measurements
8 steps
Match the case to its mount
Select the seat-post, top-tube or rack mounting arrangement appropriate to the case. Check Back Rider versus Top Rider compatibility before fastening.
Check: The housing orientation and mount rail belong to the same arrangement.

Secure the housing and display
Fasten the mount and handlebar display using the documented attachment method. Check steering, braking, lighting and wheel clearance through their normal range.
Check: The installation stays secure and does not interfere with bicycle controls.
Set the measurement offsets
Measure each handlebar edge from the bicycle centerline. Use the upstream offset method, including the sensor half-width correction, in the device configuration.
Check: Left and right offsets are recorded from actual measurements, not guessed values.
Prepare the card and privacy settings
Confirm a working FAT32 card is fitted and set privacy zones for sensitive locations before collecting a real track.
Check: Storage is recognized and location privacy settings have been reviewed.
Acquire a stationary GNSS fix
Place the powered device still under open sky. Wait for its normal measurement view and a valid fix rather than interpreting startup coordinates as a location.
Check: The device reports a usable GNSS fix before a location test.
Check a clear ultrasonic field
In an unobstructed outdoor area, point the left sensing side toward open sky as described in the quick-start check. Allow any held reading to expire.
Check: No persistent false nearby-object reading remains in the clear field.
Approach a wall slowly
While stationary on foot, point the sensor toward a broad wall and approach slowly. Repeat for the other sensing side where the display mode supports it.
Check: The displayed distance decreases plausibly as the wall gets closer.
Record the pre-ride result
Record mount type, firmware, offsets and the stationary test result. Correct any fault before riding; keep attention on traffic during later use.
Check: The installation has passed a repeatable pre-ride check.
