Why a wheel motor?

All yulbikes are equipped with a motor on the rear wheel. This one develops a nominal power of 350W and goes up to 500W in instantaneous power. This type of motor requires no maintenance, is affordable and is extremely reliable and robust.

What if I get a flat tire?

If you ever get a flat on the rear wheel, simply unplug the engine and remove the wheel as usual. The rear wheel is however heavier to handle. Take a picture of the washers on both sides of the wheel to put everything back in position when reassembling. If you are not comfortable doing this, call a bike repair shop near you and tell them you have an electric bike with a rear wheel. They will be able to do the repair for you very quickly.

Recharge time and cost, battery energy.

The battery is 374Wh. The cost of a full recharge in $CAD considering a price of $0.08 per kWh is : 3 cents. The recharge time of the battery is 4 to 6 hours.

Does the engine make noise?

The motor is brushless and does not make any noise as such. We do not have a decibel measurement to evaluate the hearing discomfort, but in practice the bike does not make any noise like any electric vehicle.

What is the type of braking?

For the urban and city bikes the brakes are 160mm Tektro mechanical discs.
For the phantom we chose a 180mm hydraulic disc brake from Tektro.

Can the bike be used without the motor or the battery (for example, when going downhill for several kilometers or on the flat if you want to be propelled only by your legs)

Yes, the yulbike behaves like a normal bike when the battery is empty or when riding downhill. You just have to set the electric assistance level to 0 or turn off the ignition. That's why there is no regeneration mode.

Can I ride in the rain?

We do not recommend riding in the rain. However, if it happens during your ride, be sure to clean your screen, throttle, control lever and frame with a dry cloth. A dry bike is a healthy bike.

Can I store my bike outside

If you ride your bike to work and your bike has to stay outside all day, we strongly recommend you to buy a bike cover. Indeed, it will not cost you too much and will protect your bike against UV rays and rain if it stays outside for 8 hours. At home, it is recommended not to leave the bike outside without protection but rather to put it in a garage, a basement or a well ventilated shed without chemicals (such as chlorine or other).

Can I ride my bike in the winter?

Yes, it is possible to use your bike in winter. In fact, many of our customers do so. However, you will need to maintain the bike extremely well. After each ride, it should be dried properly with a dry cloth. Water, calcium and mud are not good friends if you want to keep your bike healthy for many years. Also note that the lithium battery can lose up to 40% of its capacity in very cold weather.

Brakes

The disc brakes on my bike are making a lot of noise, what should I do?

There are several reasons why your bicycle's disc brakes may be making noise. Here are some steps you can take to try to solve the problem:

Check the condition of the brake pads: if the pads are worn or damaged, they may make a noise when they rub against the brake disc. You should replace the pads if they are worn or damaged.
Clean the brake discs: Brake discs can accumulate dirt, dust and grease, which can cause noise when in use. Use a clean, dry cloth to wipe the discs and remove any accumulated dirt.
Check the alignment of the brakes: If the brakes are not properly aligned, they may make a noise when used. Make sure the brakes are properly aligned and that the brake pads are parallel to the brake discs.
Check the condition of the rotors: if the rotors are damaged or bent, they may make a noise when they rotate. If you notice any damage or bending on the rotors, you should replace them.
Check the condition of the screws and bolts: If the screws and bolts that hold the brakes in place are unevenly tightened or damaged, they can cause noise when the brakes are used. Make sure all screws and bolts are tightened evenly and replace them if necessary.

If you have followed these steps and the problem persists, you may need to have your bike professionally serviced. An experienced bike mechanic will be able to diagnose and solve the disc brake noise problem effectively.

How to properly clean bicycle disc brakes?

Here's how to properly clean your bike's disc brakes:

Remove the front and rear wheels of your bike to access the disc brakes. If you have trouble removing the wheels, consult your bike manual or ask an experienced bike mechanic for help.
Clean the brake discs with a clean, dry cloth. Wipe the discs to remove accumulated dirt, dust and grease.
Use a disc brake degreaser to clean the brake pads. Apply the degreaser to a cloth and wipe the brake pads until they are clean.
Reassemble the front and rear wheels of your bike and check that all screws and bolts are tightened evenly.
Test the brakes by riding them gently to make sure they are working properly. If the brakes still make a noise, you may need to replace the brake pads or have your bike professionally serviced.

It is important to clean your bike's disc brakes regularly to ensure they work properly and last longer. Remember to wear gloves and goggles when cleaning disc brakes, as they can be very dirty and contain chemicals that are harmful to your skin and eyes.

What is the difference between cable and oil disc brakes?

Cable and oil disc brakes are two types of disc brakes that are used on bicycles. Here are some key differences between these two types of brakes:

Operating Mechanism: Cable disc brakes work by pulling on a cable that activates the brake pads, which rub against the brake discs to slow or stop the bike. Oil disc brakes work by pushing oil through a hose to the brake calipers, which actuate the brake pads to brake.
Ease of Maintenance: Cable disc brakes are generally easier to maintain than oil disc brakes because they do not need to be filled with oil and have fewer moving parts. Oil disc brakes tend to require more frequent maintenance and are more expensive to maintain due to the need to replace oil and change hoses.
Braking Performance: Oil disc brakes generally have better braking performance than cable disc brakes, as they have superior responsiveness and stopping power. However, they are also more expensive to purchase and maintain. Cable disc brakes are less expensive, but have inferior braking performance.

There is no "best" type of disc brake in general, as it depends on your personal preferences and how you intend to use your bike. If you're looking for superior braking performance and are willing to pay a little more for it, oil disc brakes might be a good choice. If you're looking for affordable, easy-to-maintain disc brakes, cable disc brakes might be a better option.

How often should I change the disc brake pads on my electric bicycle?

How often you should change the disc brake pads on your electric bike depends on several factors, such as:

Brake pad quality: High quality brake pads last longer than lower quality brake pads. If you use high quality brake pads, you may need to change them less often.
Your bike usage: If you use your electric bike extensively, you may need to change the brake pads more often than a casual user.
Your weight and driving style: If you are a heavy driver or use the brakes aggressively, you may need to change the brake pads more often.
The condition of the rotors: If the rotors on your electric bike are damaged or bent, it can affect the life of the brake pads.

In general, it is recommended that brake pads be changed every 6,000 to 8,000 km or every 6 to 12 months, depending on the frequency of use and driving conditions. However, it is important to check the condition of the brake pads regularly and change them as soon as you notice that they are worn or damaged. If you are having trouble assessing the condition of your brake pads, an experienced bicycle mechanic can help you determine if it is time to change them.

Why can my bicycle's disc brake cable break?

There are several reasons why your bicycle's disc brake cable could break:

Wear: The disc brake cable can wear out over time and eventually break. This can be caused by frequent use or exposure to the elements.
Twisting: If the disc brake cable is twisted or bent improperly, it can break. This can happen if you store your bike improperly or transport it in such a way that the cable is subjected to excessive tension.
Mechanical damage: The disc brake cable can break if it is damaged by a sharp object. For example, if it passes near a metal part or is struck by a hard object.
Unevenly tightened screws and bolts: If the screws and bolts that hold the disc brake cable in place are unevenly tightened, it can cause the cable to be overstressed and break.

If your bike's disc brake cable breaks, you will need to replace it to ensure that your brakes are working properly. If you're not sure how to replace a disc brake cable, it's a good idea to call an experienced bike mechanic.
