Your electric bike is a significant investment, and proper maintenance is essential for keeping it performing at its best while ensuring your safety on every ride. Unlike traditional bicycles, e-bikes have electrical components that require additional attention, but the good news is that most maintenance tasks are straightforward and can be performed at home with basic tools.
This comprehensive guide covers everything from quick daily checks to thorough seasonal servicing, helping you develop a maintenance routine that will extend your e-bike's lifespan and keep you riding safely for years to come.
Daily Pre-Ride Checks
Before every ride, take a minute to perform these essential checks. They'll quickly become second nature and can prevent breakdowns or accidents before they happen. Think of it as your ABC check: Air, Brakes, and Chain.
Start with your tyres. Squeeze them to ensure they're properly inflated—underinflated tyres not only affect handling and efficiency but also increase the risk of punctures and rim damage. Check for any visible damage, embedded objects, or excessive wear. Most e-bike tyres should be inflated to between 50-65 PSI, but check the sidewall of your specific tyres for the recommended pressure range.
Next, test your brakes. Squeeze each brake lever and ensure it engages smoothly without going all the way to the handlebar. If the lever feels spongy or requires excessive force, your brakes need attention. While you're at it, visually inspect your brake pads through the calliper—they should have at least 1-2mm of pad material remaining.
Air: Tyres properly inflated, no visible damage
Brakes: Levers engage smoothly, pads have sufficient material
Chain: Clean, properly lubricated, no stiff links
Weekly Maintenance Tasks
Set aside 15-20 minutes each week for these slightly more thorough checks. Consistency here prevents small issues from becoming expensive repairs.
Chain Care
Your chain is one of the most important components on your e-bike, and it works harder than on a traditional bicycle due to the motor's power output. A dirty or dry chain accelerates wear on your cassette and chainring, leading to expensive replacements.
Wipe down your chain with a clean rag to remove surface grime. If it's particularly dirty, use a specific chain cleaning tool with degreaser. Once clean, apply a quality bicycle chain lubricant—use wet lube in winter or rainy conditions, and dry lube in summer. Apply one drop per link, then backpedal a few rotations to distribute the lubricant, and wipe off any excess.
Bolt Tightness
The vibrations from riding can loosen bolts over time. Check that your handlebar, stem, seat post, and wheel axles are secure. Pay particular attention to bolts on components that experience significant stress, such as your brake calliper mounting bolts and rack mounts if you carry cargo.
Never over-tighten bolts, especially on carbon fibre components. Use a torque wrench if your bike has carbon parts, and always follow the manufacturer's specified torque settings.
Battery Contacts
Inspect the contact points between your battery and the bike frame. Wipe away any dust or debris with a dry cloth. Dirty contacts can cause poor electrical connections, resulting in reduced performance or intermittent power delivery. Never use water or cleaning products on electrical contacts—a dry cloth or electronics-safe contact cleaner is all you need.
Monthly Deep Cleaning
Once a month, give your e-bike a thorough clean. This isn't just about aesthetics—cleaning allows you to inspect components closely and prevents the build-up of grime that can accelerate wear.
Start by removing the battery if possible. Using a bucket of warm, soapy water and a soft brush, clean the frame from top to bottom. Avoid directing water at electrical components, motor connections, or the bottom bracket area where the motor connects. A gentle spray is fine, but never use a high-pressure hose on an e-bike.
Clean your wheels, paying attention to the braking surfaces. For disc brakes, ensure no oil or cleaning products contaminate the rotor or pads—this can drastically reduce braking performance. For rim brakes, check that the braking surface is clean and free of embedded debris.
- DO remove the battery before washing
- DO use gentle soap and soft brushes
- DON'T use high-pressure water
- DON'T spray water directly at motor or electrical connections
- DO dry the bike thoroughly before reinstalling the battery
Seasonal Servicing
Every three to six months, depending on how much you ride, perform a more comprehensive service. This is also a good time to consider taking your e-bike to a professional mechanic for tasks that require specialised tools or expertise.
Brake System Inspection
Examine your brake pads closely. Most have wear indicator lines—if the pad material is approaching these lines, it's time for replacement. Check your brake rotors for scoring or warping. Rotors should be flat and smooth; any waviness or deep grooves indicate replacement is needed.
For hydraulic brakes, check the fluid level and look for any signs of leaking around the hose connections. If your brake lever feels spongy or the bite point has changed significantly, the system may need bleeding—a task best left to a professional if you're not experienced.
Drivetrain Assessment
Your chain stretches over time (technically, the pins wear, causing elongation). A stretched chain accelerates wear on your cassette and chainring. Use a chain wear indicator tool to check—if it shows 0.5% wear, it's time for a new chain. Replacing a chain at this point prevents the much more expensive replacement of the entire drivetrain.
Inspect your cassette teeth for shark-finning—when the teeth develop a hooked profile rather than being symmetrical. This indicates significant wear and poor shifting performance. Similarly, check your chainring for worn or damaged teeth.
Wheel and Tyre Inspection
Spin each wheel and watch for any wobble, which indicates the wheel is out of true. Small variations can be adjusted at home with a spoke key, but significant wobbles should be addressed by a professional. Check spoke tension by squeezing pairs of spokes—they should all feel similar in tension.
Inspect your tyres for cuts, cracks, or worn tread. E-bikes are harder on tyres than regular bikes due to the increased speed and weight, so they may need more frequent replacement. Consider investing in puncture-resistant tyres if you haven't already—the peace of mind is worth the extra cost.
Motor and Electrical System Care
The motor and electrical system are what make your e-bike special, and they require specific care. Most importantly, keep connections clean and dry. After riding in wet conditions, wipe down all visible electrical connections and store your bike in a dry location.
Listen for any unusual sounds from your motor during riding—grinding, clicking, or whining noises can indicate bearing wear or other issues. Most e-bike motors are sealed units that require professional servicing, so if you notice unusual behaviour, consult a specialist.
Keep a log of your motor's performance over time. Note any changes in power delivery, unusual sounds, or error codes. This information is invaluable when troubleshooting issues or during professional servicing.
Storage and Off-Season Care
If you're storing your e-bike for an extended period, there are specific steps to ensure it's ready to ride when you return. Store the battery at around 50-70% charge in a cool, dry location—extreme temperatures and full or empty storage both degrade battery health.
Clean and lubricate the chain before storage to prevent rust. Inflate tyres to their recommended pressure, or slightly lower if stored for very long periods to prevent flat spots. If possible, hang the bike or use a stand to keep weight off the tyres.
When to Seek Professional Help
While many maintenance tasks can be performed at home, some situations warrant professional attention. Motor issues, battery problems, and complex electrical faults should be handled by qualified e-bike technicians. Similarly, if you're uncomfortable performing any task or lack the proper tools, there's no shame in taking your bike to a shop.
Regular professional servicing—at least annually—is recommended even for riders who perform their own maintenance. A trained eye can spot issues you might miss and ensure your e-bike is safe and performing optimally.
By following this maintenance schedule and developing good habits, you'll keep your electric bike in excellent condition for years of reliable, enjoyable riding. The time invested in maintenance pays dividends in safety, performance, and the longevity of your investment.
