How to Store a Bike Outside Safely
Published
Gear guide by the Mobile Bike Mechanic team, with input from James Thornton
Indoor storage is always better, but many riders simply do not have the space. If a bike has to live outside, the aim is to reduce water, reduce theft risk, and stop trapped moisture doing more damage than the rain.

The honest answer
Outside storage is a compromise. Rain gets into chains, cables, bolts and bearings. A cover helps, but it does not make a bike immune to corrosion. The best outdoor setup keeps direct rain off while still allowing air to move.
A cover that traps condensation against the bike can be worse than no cover in some conditions, so fit and ventilation matter.

BTR Extra Large Heavy Duty Waterproof Bicycle Cover For 1 or 2 Bikes
£39.99
The BTR heavy duty cover is the right type of product for outdoor storage because it is thick and sized for one or two bikes. At the time of writing it was showing out of stock, so treat this as one to check rather than a guaranteed buy.

Security upgrade from Cycle Store
A cover only hides and protects the bike from weather. It is not security. If the bike is outside, budget for a real lock too.

£51.99
The Kryptonite Kryptolok long-shackle D-lock is a sensible step up from thin cable locks for outdoor storage.
How to use a bike cover properly
- Let a wet bike drip briefly before covering if you can.
- Do not wrap the cover so tightly that moisture has nowhere to escape.
- Keep the cover away from hot exhausts, sharp chainrings and rough brick edges.
- Secure the bottom so wind cannot turn it into a sail.
- Lift the cover weekly and let the bike air on dry days.
Security matters as much as weather
A covered bike can attract less casual attention, but it is not a lock. Use a quality D-lock through the frame and a fixed object, then add a secondary cable or chain for the wheels. Avoid leaving the lock resting on the ground where it is easier to attack.
If the bike is expensive, electric, or your daily transport, outdoor storage should be a last resort.
Maintenance if the bike lives outside
- Lube the chain more often, especially after rain.
- Check cable ends, bolts and exposed steel parts for rust.
- Spin wheels and listen for rough bearings.
- Check tyre sidewalls for cracking after sun and frost exposure.
- Book a service before winter if the bike is already stored outside.
FAQs
Is it OK to leave a bike outside under a cover?
It is better than leaving it uncovered, but still not as good as indoor storage. Use a breathable, secure cover setup and maintain the chain, cables and bolts more often.
Can a bike cover cause rust?
Yes, if it traps moisture tightly around the bike for long periods. Airflow and regular drying are important.
