What should I do if I have a problem with my e-bike?

First of all, to minimize problems, please make the recommended pre-ride checks every time you use the bike. Also, please have the bike regularly checked by after-sales at the intervals set in the bike passport.

In case of a mechanical problem, like flat tire, mechanical noise, inefficient or non-functional brakes, unaligned gear shifters, problems with rims, pedals, mudguards, handlebar etc., you may seek help from any bicycle repair shop. You may also fix the problem on your own, if you are familiar with bicycle maintenance.

In case of an electronic problem such as error message on the display, problem with battery, controller, motor, charger, wiring, display please turn to the seller of the bike, or official after-sales partner. Please have your bike passport with you. Please do not attempt to fix the electronic problem on your own or at any maintenance workshop that is not authorized to repair Oolter bikes.

At any time, feel free to contact Oolter team at the form below.

What are the most important features of an electric bike?

Based on the feedback from our clients people consider factors like riding comfort, design, range, brakes, pedal assist performance and durability as the most important ones. Ladies tend to give more value on the design and color, also riding comfort, ease of locking the bike, and accessories, like basket.  Men regard looks as an important factor, but expect also range, brakes and derailleur performance and riding comfort. It goes without saying, everybody expects durability and after-sales support.


What is special about Oolter e-bikes?

Oolter e-bikes look like regular bikes for an untrained eye – there is no visible battery or bulky tubes to hide the electronics. All of these extra electronics are hidden in the sleek-looking frame using the latest technology of the e-bike and electronics industry. The battery is hidden in the down-tube, brushless hub-motor is behind the free-wheel, torque sensors controlling the pedal assist are inside the bottom bracket and the controller is down in the seat tube.  All power cables are neatly hidden in the frame. In fact the only thing visible is the speed display on the handlebar to control the power on-off and pedal assist levels.


How is the electric bike working?

E-bike is in fact a regular bike that has the electric pedal assist.  The electric assist makes the takeoff and riding uphill easier, also pushing against the wind. The assistance level may be adjusted on the display.

Pedal assist is activated when the torque sensor detects the start of pedaling. The signal is sent to the controller that activates the motor by letting the power to flow there from the battery.  Motor helps to spin the wheel as long as the rider keeps pedaling.  As soon as the pedaling stops, the electric assist is cut. The assist is also cut when the speed reaches 25km/h.


Can I ride the e-bike when the battery is out of juice?

If the battery runs out of juice, you may continue using the e-bike as a regular bicycle. It may feel a bit harder to pedal at the beginning as you have been used to having the electric assist on. But the difference to regular bikes is insignificant. Compared to regular bikes without electronics inside, the e-bike is somewhat heavier (can be 5-10kg for different brands and models). There may be also a small difference from the motor resistance.  In case of Oolter e-bikes the motor resistance is almost unnoticeable.


Is it allowed to ride Oolter e-bike in the rain?

Oolter e-bikes are IPX5 water resistant. Riding in the rain and on wet roads is no problem as long as the bike is not damaged.  Please close the charging port cover carefully to avoid water damage to the charging port.  It is not allowed to wash the bike with water jets as this may damage both the electronics and ball bearings.


Should I maintain my e-bike myself?

Indeed! Every e-bike owner should take care of his or her bike. Depending on the riding style and other circumstances it is recommended to adjust the brakes, fix loose screws and other loose items from time to time.  Day-to-day maintenance also includes oiling the chain when needed. You should also check for the tire pressure every now and then and adjust it according to the recommendation in the user manual. You may also need to check if the lights and reflectors are properly attached and working. Most wear-and-tear items need attention after 200-300 kms. Pre-ride checks of brakes, lights and the integrity of the body are strongly recommended. Small maintenance in the right time can save from many problems. If maintenance at home is not an option, after-sales partners are happy to help.


How can I switch on my Oolter e-bike?

Plain simple. To turn the bike on, you first need to:

1) Switch on the battery

2) Activate the bike from the display.

To switch on the battery, push once the main switch located on the left side of the down tube. The blue light ring around the button will light up.

Once you are done riding, push the battery button once to switch off the battery. The blue light ring goes off with a delay of 5 seconds.

Battery goes stand-by after 30 minutes idle. After this has happened, you need to push the battery switch twice to switch the battery on again.  Then switch the bike on from display.


How can I charge my e-bike?

Every Oolter e-bike has a 36V 2A charger included. Use only the original Oolter charger. Charging is similar to charging your laptop and takes about 3.5 hours. The bike can be charged via the charging port on the top right of the down-tube. First insert the charger into the wall outlet and then connect it to the e-bike charging port.

The charger is on when there is a red light on charger. When charging has been completed, the indicator light turns green. There is no risk of over-charging, as the charger automatically stops when the battery is full.  It is important to replace the cover on the charging port after finishing the charging. Do not leave the charger on longer than needed (indicator light turns green).


How should I properly storage my e-bike?

Like any other electric device, please keep your e-bike in the dry place away from sun, fire, liquids and explosives, preferably at room temperature or above +10C°. When storing your e-bike for a longer time, make sure the battery is 50-70% full. Recharge if necessary in every 2-3 months.
