In short: a simple e-bike maintenance checklist keeps your bike safe, quiet and reliable for years. Check the tires, brakes and lights before every ride. Clean and oil the chain every week or two. Once a month, check bolts, spokes, brake pads and the battery. And once a year, give the bike a full service. Most of it takes only minutes.
An e-bike carries more weight and power than a normal bicycle. Because of that, tires, brakes and the chain work harder. The good news is that you do not need a workshop or special skills. A pump, an Allen key set, chain oil and a cloth do most of the job.
Why an e-bike maintenance checklist matters
Small problems grow quietly. A slightly loose bolt, a dry chain or worn brake pads all cost more to fix later. On the other hand, five minutes of checks now and then keep your bike running like new. Regular care also protects your warranty, because damage from neglect is not a manufacturing fault.
E-bike maintenance checklist before every ride
- Tires: squeeze them. Do they feel firm? Any cuts or glass?
- Brakes: pull both levers. They should feel firm and stop the bike.
- Lights: switch them on and check front and rear.
- Battery: is it locked in place and charged enough for the ride?
- Quick look: nothing loose, rattling or hanging down.
Weekly e-bike maintenance checklist
Check the tire pressure
Fat tires lose air slowly, and you rarely notice it by eye. So use a pump with a gauge every week. Ride at the pressure printed on the tire wall: lower for grip on soft ground, higher for range on hard roads. Correct pressure also protects the rims and prevents pinch flats.
Clean and oil the chain
First, wipe the chain with a dry cloth while you turn the pedals backwards. Then put one drop of chain oil on each link. Finally, wipe off the extra oil, because a wet chain collects dirt. After rain or a muddy ride, do this straight away.
Wipe the bike down
Use a damp cloth or a soft brush. Never use a pressure washer: it pushes water into the motors, bearings and electrical connectors.
Monthly e-bike maintenance checklist
Brake pads and discs
Look at the brake pads through the caliper. If the pad material is thinner than about 1.5 mm, replace them. In addition, keep the discs clean and free of oil. Heavier riders and hilly areas wear pads faster, which is completely normal.
Bolts and quick checks
Next, check the handlebar, stem, saddle clamp, pedals, rack and fender bolts with an Allen key. Tighten anything loose, but do not overtighten. Afterwards, lift the bike and spin each wheel to check that it runs straight.
Spokes
Squeeze pairs of spokes together. They should all feel equally tight. Hub motor wheels carry a lot of force, so a loose spoke deserves attention quickly.
Gears
Shift through all gears. If the chain skips or hesitates, a small turn of the barrel adjuster usually fixes it. Our guide to the Shimano gear shifter shows how. Shimano also publishes free service manuals for its gear parts.
Battery and connectors
Check the battery contacts and cable connectors for dirt or moisture. Keep them clean and dry. Moreover, charge the battery regularly; lithium cells prefer being between 20% and 80% to sitting completely empty or full for weeks.
Every year: a full service
Once a year, or every 2,000–3,000 km, give the bike a proper service. You can do it yourself if you like working on bikes. Otherwise, any local bike shop can help.
- Replace the chain if it has stretched (a chain checker costs only a few euros).
- Bleed the hydraulic brakes if the levers feel soft.
- Check the suspension fork and rear shock for oil leaks.
- Check the wheel bearings and headset for play.
- Inspect the tires for wear and replace them if the tread is worn.
- Check that all cables and wires are intact and not rubbing on the frame.
Seasonal tips
Winter: road salt is hard on the chain and bolts. Wipe the bike and oil the chain after every salty ride. Read our tips to ride an e-bike in winter and, if you take a break, store the battery correctly.
Spring: after a long rest, charge the battery fully, pump up the tires, oil the chain and check the brakes before the first ride.
When to ask for help
Some jobs are better left to experts. For example, contact us if the display shows an error code, a motor makes unusual noises, the battery loses range suddenly or anything electrical gets wet inside. Send a short video to our support team, and we will help you find the cause. Spare parts such as a replacement charger are in our accessories shop.
E-bike maintenance checklist: the bottom line
To sum up, good care is mostly habit. One minute before each ride, ten minutes a week and a quarter of an hour once a month keep your e-bike safe and smooth. Follow this e-bike maintenance checklist, and your bike will reward you with years of trouble-free riding. For more tips, read how to enjoy a long-lasting Shengmilo e-bike.
