The Cycling Tech Brief: the cycling tech that actually matters today — and whether to update, wait, or ignore.

• CPSC issues second Ridstar warning in three months — this time front wheels are detaching mid-ride — If you own any Ridstar Q20, Q20 Lite, or Q20 Pro: stop riding immediately, remove and safely dispose of the battery, and do not sell or give the bike away.
• Cube recalls all 2026 hybrid e-bikes with ACID Carbon Hybrid cranks — aluminium pedal inserts can suddenly detach — Stop riding your 2026 Cube hybrid immediately, check your frame number at cube.eu, and book your free crank replacement at an authorised dealer — do not ride until the swap is done.
• Garmin Edge Q2 2026 update (v31.30): on-device gear tracking and Bosch Smart System live data land across the full current Edge line — Apply the free update now — Gear Tracking works even if you don't have a Bosch e-bike, and it's worth setting up component baselines before your next chain replacement.
