Troubleshooting

Check that the battery is charged

We know it sounds silly, but it’s always worth double checking that your battery is actually charged! Press the green button in the middle of the battery to show you the state-of-charge display.

If you have a battery with a round button:

If the charge indicator on the battery has 1 flashing green light, charge the battery for the full 3 hours. Plug the charger into the charging port on the back of the battery before plugging it into the mains. As the battery charges, the LEDs will light up green in turn. Once fully charged, 4 solid green lights will show. 

If you have a battery with a square button:

If the LCD display on the battery reads ‘0%’, charge the batter for the full 3 hours. Put the battery into the charging stand before plugging it into the mains. As the battery charges, the LCD will display that it’s ‘charging’. Once fully charged, the LCD display will display ‘FULL 99%’ – this means the battery is fully charged.

Check that the battery is fitted correctly

The battery slots on to the cradle on the bike frame. It will click into place when positioned correctly. 

The battery terminals may be dirty or damaged

If the battery terminals or cradle terminals are dirty, it may be preventing your eBike from functioning properly. Make sure you keep the battery and cradle clean in order to maintain your eBike’s cleaning performance.

Remove the battery and use a dry, soft cloth to wipe it clean. The battery terminals are located on the back of the battery at the bottom. Wipe the cradle terminals, too – these are located at the bottom of the battery cradle. 

The On/ Off button is faulty

The eBike battery is operated by an On/ Off button. When pressed once, the battery will turn on. Pressing the button again will now switch between ‘Max’ and ‘Eco’ mode. Pressing and holding the button will turn the battery off. If your eBike battery does not work like this, try to charge the battery and see if anything comes up on the display. If nothing appears, please get in touch with us as we may need to send you a replacement part.

The battery is intermittent or cutting out

The battery cable may have come loose or be dirty. Find the cable that runs from the battery cradle to the motor on the back wheel - there is a connector in the middle of this cable. Pull the connector apart and clean the terminals, then push it back together. Make sure it is securely fitted and try using the eBike again. 

Is it constantly in Max mode?

If you’re constantly using your eBike in ‘Max’ mode, the run-time will be reduced. You can easily swap between the two modes (‘Max’ and ‘Eco’) while you ride by pressing the On/ Off button once. 

Check your tyre pressure!

Issues with the battery holding its charge could relate to tyre pressure. The tyre pressure should be a minimum of 50psi and a maximum of 75psi, as this is the optimum way to ride your eBike and sustain the charge and longevity of the battery. 

Why aren’t I achieving the suggested radius?

Our eBikes are designed to achieve up to 30 miles per charge, but the radius you reach will vary depending on a number of factors.

 - Check your tyre pressure – it should be between 50psi and 75psi

 - The speed the bike is ridden at and the number or stop/ starts will determine how far you can ride per charge

 - Heavier conditions such as mud, soft sand and strong winds will affect the reachable radius

 - Harder terrains, including hills, will also affect how your radius

 - Rider fitness and weight makes a huge difference, as does any additional weight, e.g. luggage. The recommended maximum total weight is 110kg (17.4 stone).

Is the battery losing power?

If you’ve not used your eBike much, the battery may need conditioning. When the battery is new, you need to make sure you fully charge the battery and then fully drain the battery down to 0% for the first few charges. This will condition the battery to take the full charge and hold it more efficiently.

We also recommend this is done once a month to prolong the life of the battery and keep it working normally.

The pedal-assist has stopped working halfway through riding

The pedal-assist on the eBike will stop if you exceed 15 mph. The motor will cut out but you are still able to ride the eBike normally, and above 15 mph, without the pedal-assist.

If your speed drops below 15 mph, the pedal-assist will kick back in.

If you have a battery with a round button: Check the battery display

•1 green light

Charge the battery for 3 hours until all 4 lights turn solid green.

•4 cycling red lights or 1 red light

The battery needs charging. Plug the charger into the charging port on the back of the battery before plugging it into the mains. As the battery charges, the LEDs will light up green in turn. Once fully charged, 4 solid green lights will show.

•4 solid red lights

This suggests that the battery has been stored in extremely hot/cold temperatures. Keep the battery somewhere room temperature for 24 hours and then fully charge the battery for 4 hours.

If there are still 4 solid red lights, get in touch with us as you may need a replacement part.

•0 lights while on charge

Check that the charger is fitted correctly to the battery. The light on the charger should illuminate green.

If there are no lights on the battery while it’s on the charge, but there is a flashing green light on the charger, the battery is fully charged.

Press the green button on the battery – if 4 solid green lights illuminate, the battery is fully charged.

If you have a battery with a square button: Check the battery display

•Error 01 / Error 02

This suggests that the battery has been stored in extremely hot/ cold temperatures. Keep the battery somewhere room temperature for 24 hours and then fully charge the battery for 4 hours.

If there is still an ‘Error 01 or 02’, display, get in touch with us as we may need to send you a replacement part.

•Error 03 / Error 04 / Error 05 / Error 21 / Error 23 / Error 24 / Error 25 / Error 26

With the battery attached to the bike - the battery cable may have come loose or be dirty. Find the cable that runs from the battery cradle to the motor on the back wheel - there is a connector in the middle of this cable. Pull the connector apart and clean the terminals, then push it back together. Make sure it is securely fitted and try using the eBike again.

If the error still displays remove the battery from the bike and switch battery off for approximately 5 minutes then switch battery back on and try again.

Check the charger

If you’ve worked your way through the above steps and your eBike is still not working, it may be an issue with your charger. There are a few ways you can check if there’s an issue with the charger.

If you have a battery with a round button::

When the Battery is put into the charger there should be a Red light will illuminate on the charger and pulsating green lights on the battery while it charges. The red light on the charger to turn green once fully charged. If there are no lights illuminated, continue to the next step.

If the battery is fitting loose in the charger, there will be excessive movement when the battery is plugged in, so get in touch with us as we may need to send you a replacement part.

If you have a battery with a square button:

Put the battery into the charging stand, before plugging it into the mains. As the battery charges, the LCD’s will display it is charging. Once fully charged, the LCD display will display 99% FULL – this means it is fully charged. If there is no display on the LCD, continue to the next step.

If the battery is fitting loose in the charging stand, there will be excessive movement when the battery is plugged in, so get in touch with us as we may need to send you a replacement part.

Checks for both style batteries

Check to see if the charger gets warm when it is charging the battery. Check for signs of damage to the charger cable. If it’s ripped or frayed or If the terminals pins/charger pin is broken, you need a replacement charger to ensure your eBike works safely.

Check for signs of damage to the battery terminals. If you can’t see anything wrong with your charger but it’s still not working, try plugging it into another socket as it may be an issue with the mains or If you have a spare charger try that one instead.

If you’ve taken all the steps to check your battery and charger, get in touch with us as we may need to send you a replacement part.

*The eBike uses a quick release battery system. Lightweight 200Wh Lithium-ion battery packs can be swapped in seconds at the roadside. Each pack weighs just 1.4Kg, so spare battery packs can easily be carried for longer trips. The range that can be achieved from each pack will vary according to the conditions and effort exerted by the rider. Ranges up to 30 miles can be achieved per each full eBike battery charge. Less fit riders may achieve ranges of 10 miles or less, particularly in challenging conditions like steep hills, strong head winds or soft terrain. The conditions which affect the range are rider fitness, weight, size and seating position, head or tail winds, gradient, terrain, tyre pressure, what gear is used, number of stop/ starts and the speed the bike is ridden at.

All products ordered from www.gtech.co.uk or by telephone from Gtech are covered by a 30-day money-back guarantee. If you change your mind, we ask that you return the product to us in its original condition in its original packaging with your proof of purchase within 30 days. We will happily either exchange it or give you a full refund. Please note we are happy to arrange the return carriage but we do ask that you cover the cost which incurs a charge of £50. Our 30-day money-back guarantee does not affect your statutory rights.
