Options

1.1 Pedal assistance

Your e-bike has electrically powered pedal assistance. Thanks to the motor, it takes less effort to pedal. The motor provides appropriate assistance, depending on your speed and strength. So it's easy to start up and you also get a little extra nudge during the ride too.

The power assistance gives you more speed, so practise first out of traffic.

The effect of the motor kicks in as soon as you set off. It's best to engage the lowest level of assistance when setting off.

You can also use the bike without the pedal assistance. Bear in mind that the bike's lights don't work if the e-bike's power isn't switched on.

Switch off the pedal assistance when you get off. If you're walking and pushing your bike, use the 'Walk assist' option.

1.2 Assistance profiles and power levels

It's easy to adjust the pedal assistance to your preference and your route. Select the profile you want in the app and use the console on the e-bike to switch between various levels of assistance.

The degree of pedal assistance depends on your speed, the assistance profile you selected and how full the battery is.

The assistance of an e-bike motor is legally limited to a speed of 25 km/h (15½ mph). As you approach the maximum speed, the assistance from the motor will gradually decrease.

Important: the more powerful the assistance profile you select, the shorter the range of the battery.

The A-weighted emission sound pressure level at the driver ears is less than 70 dB(A)

2. Before we go

Prepare for your trip.

Important | Register your bike

2.1 Register your e-bike

You can use the VIN number (Vehicle Identification Number) of the e-bike to register and identify the e-bike and to activate the warranty. You will find the VIN number on the steering head. If you have a middrive bike, the frame number will be above the crank axle.

Important: We recommend you make a note of both the VIN number, the number of the key and the date of purchase and keep it in a safe place. In the event of theft or loss, this will help us help you faster and better.

Settings | Saddle and handlebars

2.2 Setting the height of the saddle

In order to determine the correct height for the saddle, sit on the bike and put your feet on the pedals in the lowest setting. If you knee is slightly bent, the pedals are correctly adjusted. If your leg is straight or you can barely reach the pedals, the saddle is too high. If you are able to put your foot flat on the ground, the saddle is too low.

Use an Allen key to adjust the height of the saddle.

Don't forget to tighten all bolts properly after you've adjusted the saddle.

Watch out for the exposed helical springs under the saddle. Cover these to prevent a child's fingers from getting caught in them.

Getting it ready for the road

To ensure that the vehicle is ready for use, it is important to tighten the bolts and screws to the specified torque. Overtightening can lead to cracks and fractures. The table opposite lists all the prescribed tightening torques.

Recommended tightening torques

Handlebar stem bolt

Cranks with square section

2.3 Installing the Seatpost And Saddle

If the seatpost/saddle assembly has been removed for shipping, install it in the seat tube. You may need to slightly loosen the clamp bolt this type requires an allen wrench to tighten or loosen a bolt that clamps the seat post in the seat tube. . Aluminum frames: Grease inside the seat tube and on the seat post. Grease prevents corrosion which can cause a seatpost to seize in a frame.

All seat posts have a minimum insertion line. The seat post must be inserted far enough into the bike seat tube to cover this line. Do not ride without properly adjusting the seat post height and securely tightening the seat post clamp or quick-release clamping mechanism. Failure to observe the minimum insertion line or properly tightening the clamping mechanism could result in seat post system failure, which could lead to an accident, with risk of serious injury, paralysis or death.

Settings | Saddle and handlebars

2.4 Installing the Handlebar And Stem

Your bike will normally be shipped to you with the handlebar assembly (handlebars, brake and shift levers with all cables attached) inside the bike, but turned 90 degrees. Place the stem + handlebar in the correct angle and fix them. Find the stem clamping bolts on the back of the stem. These are the bolts that hold the stem/ handlebar assembly in place on the steering tube of the fork. Tighten these bolts using a torque wrench to the torque value marked on the stem. If no torque marking is present, tighten to 7Nm.

2.5 Hand brakes

Before riding, make sure you know which brake lever controls which brake (front or rear) as these may be set up specific to market regulations. If you have two hand brakes, apply both brakes at the same time. The front brake provides more stopping power than the rear, so do not use it too forcefully or too abruptly. Gradually add pressure to both brakes until you slow to the desired speed or stop. If you must stop quickly, shift your weight back as you apply the brakes to keep the rear wheel on the ground.

2.6 Charging the battery

You can charge the battery both in the e-bike and separate from it.

Charging the battery in the e-bike

First connect the charger to the e-bike. Then connect the charger to the mains.

Charging the battery separate from the e-bike

Release the battery and remove it from the rear rack of the bike.

All about charging, range and maintenance of your battery.

4. Let's charge

Battery | Use and storage

4.1 Use and storage

In order to keep enjoying your e-bike for a long time, it's important that you use the battery correctly. The following tips will help you to get the most out of your battery:

Please note

→ Charge the battery as soon as it's empty. An empty battery, left to stand, can become irreparably damaged after just a few weeks.

→ Charge the battery regularly, in winter too or when you're not using it for a long period. A battery must be charged at least every three months, but every month is even better.

→ When transporting the bike by car, remove the battery or cover it.

Make sure you never let your battery run out completely before you recharge. So don’t cycle until it’s totally empty; that’s bad for the battery. If it does run out completely, attach it to the charger as soon as possible.

Points for attention

To extend the lifespan of the battery, it's important to regularly ride the bike until the battery is empty and then charge the battery fully. That's better than always topping it up after every trip.

→ If you won't be using the battery for some time, try to store it charged to roughly 70% (3-4 bars); and preferably at a temperature of 10-15° C.

If you fail to follow the most important points for attention, the battery may become damaged in the short term. Popal will examine a battery that is still under warranty and if there are signs of serious abuse, the warranty may expire. If you have any questions, please get in touch with your dealer.

Even when the battery is switched off, the bike's electrical system will use a tiny bit of power from the battery. If you're not going to be using the bike for a long time, it's best to store the battery separate from the bike.

The battery is waterproof and therefore resistant to rain. However, it's better not to expose the battery to large amounts of water.

4.2 Battery lifespan

The lifespan of the battery depends on how and how frequently it's used. With the tips in this manual, you can easily make your battery last for years. However, bear in mind that usage will always decrease a battery's lifespan.

A reduction in capacity of between 5 and 15% a year is perfectly normal.

In ideal circumstances, the battery can be charged and emptied between 1,000 to 1,500 times with the capacity gradually diminishing. If the end of the battery's lifespan is reached, it must be replaced.

Think Green

Do not dispose of batteries, chargers or accessories with household waste. All these components can be recycled in an environmentally friendly way. Take them to one of the special collection points. You can also take the battery to the dealer in your neighbourhood.

5. Parts

Your whole bike taken care of completely.

5.1 Lights

You can switch the lights on and off by briefly pushing the button below. The TFT colour display is also equipped with a light sensor that automatically switches on the lights. If you subsequently turn the lights on or off manually, this function will expire until you start up the display again.

5.2 Brakes

In order to avoid any unpleasant surprises while cycling, it's important to check beforehand which brake handle operates the front brake and which the rear brake. The left brake handle operates the front brake and the right one the rear brake.

Never use lubricant or regular cleaning agents on your brake blocks or rotors, since that can cause noise when braking and reduce the reliability of the brakes.

Hydraulic disc brakes

Disc brakes ensure a powerful braking sensations and give a strong sense of control. With disc brakes, you can adjust the brake blocks. To do so, use an Allen key to slightly loosen the bolts the caliper is attached to then tighten them again while keeping the brake handle firmly depressed.

Breaking in

Disc brakes need a 'breaking in' procedure. If you don't break them in, you won't reach the maximum braking capacity, with the risk that the brake blocks will squeak. If they do start to squeak, replace the brake blocks, clean the discs with brake cleaner and repeat the breaking in procedure.

You need a clean, dry environment for breaking in. Accelerate to 20 km/h, and brake moderately on one brake until the bike stops. Do this 20 times for each brake.

Some dealers have what is known as a breaking in machine at their disposal and can carry out the breaking in procedure for you before delivery.

Get to know the stopping capacity of your brakes well, so that you will be able to rely on your bike in the event of an emergency stop. An emergency stop using only one brake can lead to you briefly lose control of your bike. So always use two brakes at the same time. Keep your arms stretched and your weight to the back. That way, you'll stop fastest and steadiest.

5.3 Tyres and desirable tyre pressure

Not all bicycles and, in turn, all tyres are suitable for any terrain. The Popal GTX should only be used on paved/asphalt roads.

Tyre pressure greatly affects the range and comfort of your bike. So we recommend you always pump your tyres up properly. Optimal tyre pressure is between 3.5 and 6 bar. The sidewalls of all tyres display the correct inflation pressure recommended by the manufacturer. A handy aid: if you push your thumb against the top of the tread and it's possible to depress the tyre slightly, you have the correct pressure.

Check your tyre pressure every 2 to 4 weeks.

6. Maintenance

Loving attention for your new e-bike.

6.1 Servicing*

It's time to have your bike serviced for the first time after either 250 km or 3 months. After that, maintenance is mainly dependent on how intensive your use of the bike is. So discuss with your dealer what would be an appropriate maintenance plan for your situation. Popal advises having the bike checked at least every 6 months after the first service.

Naturally, there's a lot you can do yourself to keep your bike in peak condition. Our tips:

Always go for the first service. Parts such as spokes and cables can stretch after the first use of the bike. If they're not adjusted, there is a greater risk of spokes snapping or gears not engaging.

Cleaning

You can clean your e-bike by removing dirt with a soft brush and hot water. That'll get it gleaming like a showroom model again. Not only that, but regular cleaning makes sure your bike will be with you for longer. Do be careful not to use too much water around electronics and the battery. It's best to remove the battery before washing.

Don't use a high-pressure cleaner to spray the e-bike clean. The jet can damage the bike's electronics.

Aftercare

It makes sense to take care of certain parts of the bike immediately after cleaning it. Chrome components, unlacquered aluminium and stainless steel parts can be greased with acid-free Vaseline or Vaseline spray to prevent rust. Moving parts need grease/oil. We recommend you regularly lubricate the chain, cogs and axles. Naturally, your Popal dealer can do this for you too.

How do you keep your e-bike safe and looking good for longer?

→ Check the tyre pressure and tread regularly.

→ Check that the brakes are working properly and if the brake blocks are worn. Replace or repair them where necessary.

→ Check that there is enough tension in the spokes, that none of them are broken or that there is no twist in the wheel. If there is, visit your dealer.

→ Treat all moving parts and electrical contact points regularly with acid-free Vaseline spray.

*We recommend you maintain your bike regularly in addition to the periodic servicing by the dealer.

6.2 General maintenance

For urgent repairs or a major overhaul, you can always go to your Popal dealer. But you can also regularly run a check on your bike yourself. This checklist will help you keep your bike in peak condition:

Weekly

→ Is the pedal assistance working as it should?

→ Are all the gears working and does the e-bike change gear smoothly?

→ Is there enough tension on the chain?

→ Are both brakes working properly?

→ Is the saddle at the correct height? Is it still comfortable?

→ Are the handlebars adjusted correctly and are they at right angles to the front wheel?

→ Are all the spokes still whole?

→ Are the tyres pumped up to the right pressure? Is there still enough tread on the tyres?

→ Are all the lights working? Is the headlight properly adjusted?

→ Are all reflectors still clearly visible?

Monthly

→ Is your e-bike in need of cleaning?

→ Is there any damage visible?

→ Is the stand attached firmly and is it greased well?

→ Are the nuts and bolts of the brake calipers still tightened properly? Are the brake blocks and discs in good condition?

→ Do you hear any strange sounds while you're cycling?

→ Are the seat post and handlebar stem positioned correctly and are they tightened properly?

→ Have the seat post and handlebar stem been greased?

→ Is there slack in the front fork, around the steering head bearings?

→ Are all nuts and bolts properly greased?

→ Is the lock still working smoothly and has it been greased?

→ Does the bell still work and is it in the right position?

→ Are the pedals attached properly and have they been greased at the screw thread?

6.3. Major overhaul

Popal recommends you schedule a service check-up every 3 months and a major overhaul once a year. During a service check-up, your dealer will carry out the following:

Every 3 months

→ Check wheels and tyres (twists in the wheels, tension of spokes, tyre pressure and tread)

→ Check all mounting components/nuts and bolts, and tighten where necessary

→ Check brake blocks for wear, adjust cable tension, check efficiency of brakes

→ Check steering head for slack, check attachment of handlebar stem and adjust if necessary

→ Clean chain, tighten and grease with Teflon spray

→ Electrical system: Fully charge the battery, clean pedal sensor with lukewarm water and sponge, treat contacts with contact spray

→ Check drive system of the e-bike and where necessary, replace defective parts

Annually

→ Take apart, degrease, grease and put together the following parts:

- chain and cogset

- hub

- gear and brake cables

- steering head

- handlebar stem

- seat post

→ Check and grease the following parts:

- gears and shifters

- brakes and brake handles

- lock

- stand

→ Check spoke tension (tighten and/or true if necessary)

→ Check tyre pressure (replace tyres if necessary)

→ Check crankset and pedals and adjust

→ Check that lights are working properly and adjust

→ Check saddle for damage and suspension

→ Apply a protective layer of wax to the bike

→ Take the bike for a test drive to check that all parts are working as they should

- When replacing parts, always make sure that the original parts are put back in place
