E-bikes have transformed traveling, commuting and exploring across the UK. However, even the most reliable e-bikes can develop problems, and many riders experience the same common issues sooner or later. E-Movement has been helping riders diagnose and fix these faults for years and this guide draws on common experiences by electric bike riders across the UK. For full step by step details on each, you can read this full guide 20 common e-bike problems and solutions in the UK.
20 Common E-Bike Problems and How to Fix Them
If your e-bike isn’t performing as it should, it’s usually down to one of four things. The tires and brakes, the battery and charging system, the motor and controller or the display and sensors. First take care of anything that affects braking or safety. Here are the 20 most common issues with e-bikes reported by UK riders, plus easy fixes for each.
1. Rear Wheel Punctured
Switch off the battery and disconnect the motor cable connector before starting. Loosen both axle nuts and slide the rear wheel free to fit a new tyre or tube. When refitting, line up the motor cable's arrow markings correctly and secure the connection with a zip tie.
2. Flat Front Tire
Loosen the axle nut, lift the frame slightly and slide the tyre out to access the tube. When fitting the replacement, check that the brake pads are sitting flush against the disc rotor before you tighten the axle back down. Make sure the wheel is securely fitted before riding.
3. Brakes Not Working Properly
One of the most common and serious faults a rider can face is e-bike brakes not working in the UK. Most common causes are worn pads, dirty rotors or a stuck motor inhibitor. This is one of the 20 common e-bike problems and solutions in the UK that needs urgent attention. At E-Movement UK, professional brake inspection and repair can help restore safe braking, so do not ride until full braking is restored.
4. Locking up wheels
In the UK, two common causes of an e-bike wheel locking up are misaligned calipers or debris in the brake system. Turn off the bike, gently squeeze the brake levers to release trapped pressure, check the calipers for debris, and lubricate the pivot points with bicycle lubricant.
5. E-Bike Battery Won’t Charge
The first thing to do if your e-bike battery isn't charging is to test the charger with a voltmeter. No light on the indicator usually means the charger is bad. Check the internal ebike battery fuse for a broken wire and replace it if blown. A very low voltage reading means the battery management system has gone into deep-sleep mode.
6. E-Bike Battery Draining Too Quickly
The most common causes for an e-bike battery draining fast in the UK are repeatedly discharging it fully, storing it in cold British conditions, or natural cell degradation. Charge the battery when it falls to 30–50%, avoid fully discharging it, and store it at around 60% charge if it won't be used for a while.
7. MPH Displaying KPH Instead
If an e-bike display is not working in the UK as it should, it usually just means the unit of measurement needs changing. Press and hold the plus and minus buttons to get into settings and switch to MPH. This is one of the 20 common e-bike problems and solutions in the UK riders can fix themselves, with no tools needed.
8. Error Displayed E-07
If you see this among your electric bike error codes in the UK, it means a motor cable is connected loosely. Turn off the bike, unplug the motor connector, align the arrows on both sides, plug it back in tight and secure it with a zip tie. The error should clear on the next power cycle.
9. Motor Cut Out When Riding
An e-bike motor cutting out in the UK part way through a ride is normally caused by a controller that’s getting too hot, or a loose cable near the motor. Let the bike cool for 10-15 minutes, check all motor connections and lower the pedal assist level on steep UK gradients to avoid sustained thermal overload.
10. Hydraulic Brakes with a Spongy Feel
Hydraulic brake levers that feel spongy indicate air in the system or dirty brake fluid. Turn the bleed screws clockwise to tighten until the lever stiffens. If you suspect contamination following wet UK riding, the system needs a full bleed with fresh mineral oil.
11. Brake sensor error
A faulty brake sensor is one of the 20 common e-bike problems and solutions in the UK, as it can stop the motor engaging altogether, you'll see an exclamation mark on the right of your screen. Check the small sensor wire on the brake lever is tight, then test the sensor circuit with a multimeter. Replace it if there's no continuity.
12. Pedal Assist Doesn’t Work
One of the most common reasons for an e-bike pedal assist to stop working in the UK is a dirty or displaced magnet ring around the bottom bracket. With a flathead screwdriver, slide the ring closer to the sensor. If that doesn't solve it, the pedal sensor will need replacing.
13. Slack Handlebars
Open the handlebar clamp and tighten the stem bolt with the correct Allen key, taking care not to overtighten on aluminum stems. If the handlebars still feel loose afterwards, check your headset bearings too, worn bearings allow play the stem bolt alone can't fix.
14. Display Settings Not Working Correctly
Changing settings you don't understand can cause motor overheating or a locked display, so check the owner's manual first. If the display is frozen, press and hold the power button for 10 seconds to force a factory reset.
15. Throttle does not work
One of the more common reasons for an e-bike throttle not working in the UK is it sticking at the rearmost position. Carefully pull it back to the rest point by hand. If it doesn't return, the spring return mechanism is worn out and needs a replacement part, that's one of the 20 common e-bike problems and solutions in the UK.
16. Different percentages on battery and display
This is not a bug. Heavy riding causes voltage to sag, which shows a lower percentage than the battery's actual charge. The two readings line up again once you reduce your speed or assistance level.
17. The controller is not working correctly
An e-bike controller fault in the UK can make the motor behave erratically. Surging, running too slowly, or cutting out altogether. Check all wiring connections for looseness or corrosion, reset the circuit breaker if your model has one, and inspect the fuse. Replace the controller if the problem persists.
18. Bike will not start after recharging battery
Draining the battery to 0%, which sends the Battery Management System into deep-sleep mode, is one of the 20 common e-bike problems and solutions in the UK. The BMS won't recover automatically on recharge, Contact your manufacturer's technical team for a manual restart. Avoid this by charging between 30% and 50%.
19. Battery wiring damage
Broken or corroded battery wire can cause intermittent or total power failure. Check the full length of the wire for burning, green corrosion or physical damage. Replacement means removing four retaining screws, swapping the wire and reassembling. E-Movement recommends an annual battery wire check on bikes ridden regularly in wet UK conditions.
20. Engine dies on re-starting
If the motor stops immediately after restarting and there's an odd smell, you most likely have a bad hub motor. Turn it on, spin the wheel, reconnect wires and run a hall test. If the motor is stiff or won't rotate, it points to an internal fault needing professional diagnosis. E-Movement UK technicians carry out hub motor diagnostics as part of their servicing program.
