How to Look After Your E-Bike Over Winter

Winter in New Zealand is wetter and muddier than most riders expect, and it takes a toll on bikes that don't get much attention between rides. The good news is that a bit of basic upkeep goes a long way. These are the things worth doing yourself, and the ones better left to a technician.

Keep the battery out of the cold

Lithium batteries lose capacity in cold temperatures and recover once they warm up again, but repeated exposure to the cold while discharged will shorten battery life over time. A few habits help:

• Bring the battery inside after rides rather than leaving it in the garage overnight.
• Store it at around 50-80% charge if you are not riding for a few weeks.
• Let it reach room temperature before charging after a cold ride.

Wipe down after wet rides

Mud and road grime work their way into cables, contact points, and bearings. A quick wipe-down after each wet ride takes two minutes and prevents the kind of slow corrosion that turns into expensive repairs.

• Use a damp cloth on the frame, motor casing, and display.
• Avoid high-pressure hoses directly on the motor, display, or battery contacts.
• Dry off the brake rotors and any exposed metal before storing the bike.

Look after the chain

The drivetrain takes the most punishment in winter. Wet conditions wash lubricant off quickly, and a dry or dirty chain wears faster and puts more load on the motor.

• Clean the chain regularly with a dry cloth to remove mud and grit.
• Reapply a wet-weather chain lube after cleaning, not before. Putting lube over dirt accelerates wear.
• If the chain feels stiff or makes a grinding sound, it needs attention before the next ride.

Check your brakes

Brake pads wear faster in wet conditions. You do not need to be a mechanic to check them: most brake pads have a wear indicator line, and if the pad material is getting thin, it is time to replace them. Brake lever feel is also a useful indicator. If the lever is pulling further toward the handlebar than usual, the pads or cable tension need adjustment.

Tyres and tyre pressure

Wet roads require more traction, and running slightly lower tyre pressure in winter gives you a little more contact patch. Check the recommended pressure range printed on the tyre sidewall. Soft tyres in cold weather are common since air contracts, so check pressure more regularly than you would in summer.

• Inspect tyres for cuts or embedded debris after muddy rides.
• Replace tyres before the tread is completely smooth, particularly heading into the wetter months.

Keep contacts and connectors clean

The battery contacts and any waterproof connectors on your e-bike can collect moisture and grime. A small amount of dielectric grease on battery contacts helps prevent corrosion. If you notice any corrosion or intermittent power behaviour, get it looked at early rather than letting it develop.

When to get a professional service

There is a limit to what you can do at home without the right tools and diagnostic software. A professional service picks up things that are harder to spot yourself, including motor system checks, software updates, cable wear, bearing play, and hydraulic brake condition.

At Electrify, we offer three service options depending on what your bike needs:

• Safety Check ($79) covers brake adjustment, tyre inspection, and a bolt safety check. A good option if the bike feels fine but you want peace of mind heading into winter.
• Standard E-Bike Service ($139) is the annual service recommended six months after purchase and yearly thereafter. Covers everything in the safety check plus chain inspection and lubrication, gear adjustment, a basic clean, and drive system software update where applicable.
• Advanced E-Bike Service ($249) is worth considering if the bike has had a hard season or hasn't been serviced in a while. Includes hydraulic brake service, wheel true, drivetrain clean, cable replacement if needed, and a full bearing assessment.

If you are not sure which option suits your bike, the team at your nearest Electrify store can advise before you book.

A bit of attention over winter means your e-bike is ready to go when the days get longer. The basics take very little time, and a professional service once a year takes care of the rest.
