"Reported my bike at 9am, someone spotted it behind Olson by noon. Got it back the same day."
— Maya, 3rd year"Stored my bike here over summer for way less than a storage unit. Picked it up in September, perfect."
— Diego, 2nd year"Checked a serial before buying off Marketplace — it was flagged stolen. This app saved me $300."
— Priya, 4th yearQuestions, answered
Is it really free?
Yes — registering bikes, reporting theft, serial lookups, and the theft map are free forever for students. Premium ($2.99/mo) adds SMS alerts, a metal tag, and perks.
Who can make an account?
Only people with a verified @ucdavis.edu email. We confirm your inbox, so the community stays Aggie-only.
Is my personal info public?
Never. The registry only shows bike details (make, color, serial, general location). Your email, phone and address are never published, and serial lookups never reveal an owner.
Are you affiliated with UC Davis?
No — AggieBikeGuard is an independent student project, not affiliated with or endorsed by UC Davis or its police department.
Ready in 60 seconds. Free forever for students.

Stop Thieves Cold
The cheapest insurance is locking up right. Here's what actually works.
The U-lock + cable combo
U-lock through the rear wheel & frame to a rack; cable secures the front wheel. Ditch cheap cable-only locks.
Photograph your serial
Photograph the serial the day you get the bike. No serial = nearly impossible to recover.
Park in the light
Use high-traffic, well-lit racks near entrances. Check the theft map for hotspots to avoid.

📈 Quick math to grow your bank account
If 4,000 students sign up (≈10% of cyclists) and 5% go Premium: ~$600/mo recurring. Add 30 summer-storage bookings (~$12 fee each = $360), 40 repairs/mo ($5 avg fee = $200), 5 sponsor shops ($245), and insurance referrals (~$10 each). That stacks toward $1,500–2,500/mo — see the guide for the playbook.
