Problems with the engine and assistance
The engine does not work anymore
We know the error and are working on the error description. If you need an answer quickly, just contact us!
Weak engine support
If the Go SwissDrive motor suddenly produces significantly less power than before, this can be due to a number of factors. The error is mostly shown when the motor offers less power than before while applying the same amount of force to the pedals. One possible reason is an incorrect parameter set that was installed during a service or at the time of purchase of the e-bike. To remedy this, we recommend that you contact your dealer or us and have a new parameter set installed.
Another possible reason for reduced engine power may be a fatigued or deteriorated torque sensor. In this case, we recommend that you first have the motor recalibrated. If this does not improve the situation, the torque sensor may need to be replaced. You can either send us the complete rear wheel or just the motor.
Another possible reason for a weaker engine response can occur in cold weather below 2 °C, when the bike has been exposed to the cold for a longer period of time. The manufacturer installed elastomers in the torque sensors during a short period of time, which become hard after longer use and at low temperatures, so that more force has to be applied when pedaling. This problem disappears again at higher temperatures. To remedy this, we recommend either moving the bike to a warmer place, switching up the support level or sending the motor to YouMo so that the torque sensor can be replaced.

Problems with the display
The display cannot be switched on
An error message is shown on the display

Pressing individual buttons on the display produces no response
A common error is that the display can be switched on, but individual buttons no longer work. This may be due to incompatibility of the display with the docking station or a damaged docking station. To determine the cause, you should compare the part numbers of the display and the docking station. See the table below for instructions. If the display and docking station are compatible, but certain buttons do not work, you will need to replace the docking station. You can find the right product in our webshop, either here for CAN-Bus displays or for Bikebus displays up to 2015 or Bikebus displays from 2016.
Display fogs up
The Go SwissDrive EVO display is basically protected from rain, moisture and snow and the housing is sealed. In rare cases, however, the display may still fog up. A possible cause for this can be that the display is exposed to humidity for a longer period of time at changing temperatures, and air with higher humidity is drawn in due to different pressure conditions indoors and outdoors. Since cold air can absorb less water than warm air, the display can then mist up. A good way to remedy this is to place the display in a container of rice in a warm place, for example, and the rice will absorb the moisture.
As a preventive measure, you can also simply remove the display from the docking station if you leave it outside for a longer period of time.
The display shows a faulty indication on the screen and all the keys may no longer function properly
If the display shows a faulty indication on the screen, sometimes the screen displays overlap when you press the menu key, it is possible that the file system of the display is damaged. In addition, sometimes the display can be switched on but not switched off. We can try to update the software of the display and restore the file system. Please send us, YouMo, the display for this purpose. Please use our repair and service form.

The battery goes into short circuit mode
If your battery goes into short-circuit mode, it means that it has automatically cut off the power and voltage supply to the system due to excessive electricity flow. This is indicated by flashing LEDs on the battery when you press the button on the battery. This is a protection mode of the battery, whereby it no longer outputs voltage. The reason for this can be a temporary or permanent fault in the wiring harness or a defective motor.
To verify the problem, you can reset the battery. To do this, press and hold the button on the battery for about 10 seconds until the second LED on the battery lights up. Then reconnect the battery and press the button on the battery. This restarts the battery. If the problem was temporary, the LEDs light up one after the other. If the problem is permanent, all LEDs light up in parallel and the battery of your eBike has gone into short-circuit mode again. In this case, you should contact your specialist dealer or YouMo to have a repair carried out.
The capacity indicator on the battery decreases after a few days without me using the E-Bike
If this occurs, it is very likely that the cells of the battery are faulty. In this case, you should stop using the battery and contact your specialist dealer or YouMo to have it repaired.
Other Problems
Cracking in the area of the rear wheel while riding
While riding your E-bike, you may experience a crackling noise. This can have many different causes and the location of the crackling is often difficult to find. However, there are some typical signs that can help you determine the cause of the problem.
A distinction is made between the following phenomena:
- Occasional occurrence of the cracking sound
- Constant occurrence of cracking
- Cracking only under load
- Cracking when turning the rear wheel without load
- Cracking when turning the pedals without load
- Cracking when pedaling with load
- Time of occurrence of the cracking noise
- After the first several hundred kilometers of use
- Only when cornering, mostly in one direction
- After a certain period of driving (e.g. after 20-30 minutes)
- After a longer period of use (several thousand kilometers)
- When the temperature changes (cold to warm, warm to cold)
Possible causes for the cracking can be:
- Spokes slightly loose or different spoke tension (1, 2, 3, 7a-d).
- Screws on the motor housing slightly loose (1, 2, 3, 6, 7a-c)
- Worn pawls of the freewheel (1, 2, 4-6, 7c-e)
- Dirt and/or grease on the freewheel that has hardened and latches that will sometimes be stuck (1-6, 7c-e)
- Chain that has lengthened due to use (1, 2, 5, 6, 7d)
- Interlocking for freewheel on motor that are worn (1, 2, 4-6, 7c-e)
- Bearings in the motor that are worn (1, 2, 6, 7 7c-e)
- Bearings in bottom bracket worn out (1-3, 6, 7c-e)
- Heavily soiled rear derailleur (1, 2, 5, 6, 7d-e)
In cases F and G, you may need to send the motor or the complete rear wheel to YouMo.
To prevent cracking, we recommend that you have your eBike serviced regularly or have it serviced by your dealer.
Pedals can be partially pedaled
If the pedals can be partially pedaled there is probably a defect in the freehub cassette body of your eBike. We strongly recommend that you stop riding to avoid damage to the motor. The freehub cassette body should be removed and replaced by a specialist dealer. If you are technically experienced, you can also remove and replace it yourself. You can buy spare parts for this in our online shop. It is also important to check the gearing on the motor where the pawls of the body engage for damage. Often, pedaling is preceded by a clicking noise in the area of the rear wheel. We have created a separate section for this in the FAQ. Early maintenance of your electric bike will prevent major damage to the motor.
