Tools Required for Assembly

• 3 mm Allen Wrench
• 4 mm Allen Wrench
• 5 mm Allen Wrench
• 6 mm Allen Wrench
• #2 Phillips Screwdriver
• 15 mm Wrench
• 4 mm Wrench

Assembly Steps

1. Open the carton. Be careful of staples. Remove the bike from the box. This operation may be easier with two people. Lean the bike against a stable support. Place it on a non-slip surface. Carefully remove all packaging and protective material from the bike. Recycle them if facilities are available.
2. Apply a thin layer of grease to the inside of the frame's seat tube. Insert the seatpost and adjust the quick-release lever to secure the post firmly in place. Secure the bike by the seatpost. If the bike is equipped with a suspension seatpost, do not secure it on or above the suspension mechanism collar.
3. The pedals are marked L (left) and R (right). The R pedal is for the crank on the chain side. It screws in clockwise using a thin 15 mm wrench. The L pedal is for the side opposite the chain and screws in counter-clockwise. Ensure both pedals are tightened to a torque of 40 Nm.
4. Remove the top cap by loosening the Allen screw on the fork's steering tube. Being careful not to let the fork drop, install the stem onto the steering tube and tighten the center screw until all play in the headset is eliminated (while ensuring the bearings turn freely and are not too tight). Align the stem with the fork and tighten the stem screws using a 4 mm torque wrench to 5 Nm.
5. The front wheel quick-release skewer can be installed with the lever on the left or right side. Install the wheel so that it is centered in the dropouts, then tighten the quick-release skewer.
6. The front fender and headlight attach to the fork crown using a 5 mm Allen bolt, and to the lower part using 4 mm Allen bolts. Some bikes may also require 8 mm nuts to secure the fender stays. Connect the headlight, paying attention to the connector notch. Aim the headlight to illuminate a distance of 5 meters in front of you when seated on the bike.
7. Check that all nuts and bolts on the bike are securely tightened, especially those for the saddle, seatpost, stem, and handlebars. Ensure all levers and controls are easily accessible, unobstructed, and that the gears and brakes function correctly and safely.
8. Inflate your tires according to the manufacturer's recommendations indicated on the tire sidewall.

Adjustments After Assembly

Mechanical/Electrical Components

• All controls and levers on the handlebars are adjustable left, right, up, and down. These adjustments may require a screwdriver or Allen wrench.
• Ensure all levers, buttons, and controls are visible and easily accessible.
• Make sure no obstacle obstructs the operation of the levers, buttons, and controls.
• Brake levers should be angled between 3 and 4 o'clock on a dial and easy to reach with your hands on the grips.
• The display should be oriented to be visible from the seated position on the bike.
• Function buttons (up, down) should be accessible when your hand is on the grip.
• Ensure that adding any accessory such as a mirror, phone mount, basket, or any other item attached to or on the handlebars does not hinder access to or operation of the levers and buttons. Check that control cables are not pulled or blocked by accessories added to the handlebars and their area.

Seatpost and Saddle

• The most efficient riding position is achieved by adjusting the saddle so that your leg is almost straight when the pedal is at the 6 o'clock position. This means that when stopped, you should touch the ground with the tip of your toes. If this position is not comfortable, lower the saddle for optimal comfort and safety. As you get used to the bike, your goal will be to raise the saddle to achieve an efficient riding position.
• The seatpost has a "minimum insertion height" or "maximum extension" mark. Do not exceed this mark when installing the seatpost, as this could damage the post and frame, which is not covered by the warranty.

Disc Brakes

This bike is equipped with hydraulic disc brakes. A hydraulic brake is a sealed system that should not be tampered with, except with appropriate tools. In general, these brakes require little maintenance, but it is advisable to have them checked at each service (once a year or as needed) and to change the brake fluid if necessary. These operations should only be performed by a qualified technician.

Transmission

• Your bike is equipped with Shimano brand "indexed" gears. A simple "click" on the lever moves the derailleur to shift the chain to the adjacent cog on the rear wheel, either to a higher or lower gear, depending on your selection via the handlebar lever.
• If the gears do not engage quickly or make noise after shifting, the rear derailleur may need adjustment. This operation should preferably be performed by an authorized Wolff dealer. Do not delay in having the maintenance done.

Suspension Fork and Suspension Seatpost (if applicable depending on models)

Keep the seatpost and fork legs clean and dry. Do not attach or fix anything that could hinder the operation of these parts.

Maintenance and Care

Proper care of your electric bike can extend its lifespan by several years. It is therefore important to remember some basic maintenance methods for your E-Bikes.

1. Inflate Your Tires: Electric bikes are on average heavier than classic bikes, so it is important to ensure your tires are properly inflated. Properly inflated tires facilitate pedaling and acceleration, helping your motor function efficiently. Your electric bike will benefit from better range when the tires are inflated and rolling resistance is reduced. Additionally, properly inflated tires reduce the risk of punctures and protect your rims from damage, especially if you hit a pothole or curb. Consult your tire sidewall for the recommended pressure range in PSI – the amount of air pressure to aim for when inflating. Tire pressure has a minimum and maximum limit. Do not exceed these limits, as this could make the ride uncomfortable and cause premature wear of the tires, inner tubes, wheels, and the bike in general. Check your tire pressure frequently, ideally at least twice a month, and re-inflate if necessary. When checking, also inspect the tires for cuts, nicks, debris, as well as tread and sidewall wear.
2. Keep Your Chain Clean and Lubricated: Your transmission will function better and last longer if it is kept clean and lubricated. It is recommended to apply a light oil to the chain and derailleur pivot points every 200 km (125 miles) or according to the lubricant manufacturer's instructions. Additionally, chains tend to wear out and stretch over time. Be sure to replace your chain before it is too worn to avoid damaging the rest of the transmission.
3. Avoid Riding Over Curbs: As electric bikes are much heavier than traditional bikes, every time you hit an obstacle on the road or ride over a curb, the bike's components experience a greater shock. Over time, this can damage your motor and other parts of the electric bike. Furthermore, the rims are much more susceptible to deformation. When riding on rough terrain, we recommend standing up slightly from the saddle to reduce the pressure on the motor and other parts of your bike. We also advise getting off your bike when you need to go over a curb. Trust us, this will considerably extend the lifespan of your e-bike.
4. Clean Your Bike Regularly: Dirt and mud can damage the mechanical and electrical components of your bike, so it is recommended to clean your bike regularly. Avoid using high-pressure water, as it can penetrate the internal parts of your E-Bikes, such as bearings and the motor, and cause damage or corrosion. Instead, use a damp cloth and a bike-specific cleaner. Every few months, have your E-Bikes checked by an authorized Wolff dealer for safety checks and adjustments as needed.

Operating Procedures

Battery Installation and Removal

The battery for the SPARK model is located behind the seatpost. To remove the battery, you must first remove the saddle and seatpost (remove them as a single unit) from the frame. At this point, you can mark the seatpost with a marker or a piece of adhesive tape to easily find the initial height before removal. Using the key, insert it into the lock located at the top of the battery, on the left side. Turn it to the unlocked position, then, using the battery handle, pull it slowly but firmly upwards. Battery installation is done by gently sliding the battery down onto the mounting rail. Once it is fully inserted, turn the key to the "Off" or "On" position, depending on the intended use after installation. Reinsert the seatpost with the saddle, then tighten the seatpost clamp.

Battery Charging

Your Wolff charger is equipped with a standard North American plug and is compatible with 120V electrical outlets in the United States and Canada. The battery has a jack-type connector compatible with Wolff batteries. The charger has an LED indicator light: When the light is red, it means the battery is charging. When the light turns green, charging is complete. This is a simple visual indicator that tells you it's time to unplug the charger. Never leave a battery charging unattended or for longer than necessary. Batteries can be recharged directly on the bike or removed from the bike. From a low charge level, a full charge can take up to 4 hours.

Cut-off Function

Wolff bikes are equipped with an automatic cut-off function that interrupts motor power as soon as a brake lever is activated. Both brake levers are equipped with an electric sensor that detects brake use. Using either brake immediately cuts off motor power. Once the brake lever is released, if you pedal, the motor power will resume instantly.

Battery Storage

Your Wolff electric bike battery can be stored on the bike when not in use, whether for a short or long period. Store your battery in a place where it is not likely to be hit or damaged, and in a clean, dry place. If you live in a cold climate in winter (below 0 °C / 32 °F), it is preferable for the lifespan and performance of your bike that the battery, or the entire bike, be stored at room temperature. If your battery is not used for more than 3 months, it is recommended to charge it for 1 hour every 8 weeks.

Powering On/Off

All Wolff bikes automatically turn off after approximately 5 minutes of inactivity, just like mobile phones or computers go into standby mode. Some models may require an additional step to completely turn off power from the battery. These steps are described below. The SPARK requires a key, like an ignition switch, to be inserted into the battery and turned to the "On" position. After this step, press and hold the bottom right button on the display until it lights up.

Throttle

Wolff bikes are equipped with a throttle. This can be activated once the bike reaches a speed of approximately 8.5 km/h (or 5.3 mi/h). The throttle is a thumb lever located on the left handlebar, next to the grip. Please ensure you can easily reach the lever and that nothing obstructs its operation or risks snagging on it. Using the throttle allows the bike to reach its maximum speed. Please note that using the throttle consumes more battery power.

FAQ

How far can an electric bike go?

The range of your electric bike will vary depending on many different conditions, from your battery size to the weather. Some of the most common factors include battery size and age, rider weight, average riding speed, assistance level used, hilly terrain, wind, tire pressure, and outside temperature.

If your tires are deflated, they have more friction with the ground, making it difficult for you and your motor to maintain a high speed. If you live in a hilly area, your motor will have to work harder to help you climb hills. The harder the motor works, the more battery power it requires. Things like headwind and heavy loads also accelerate battery discharge.

How to optimize the range of your electric bike?

If you want to increase the distance you travel with your electric bike, keep your tires properly inflated and pay attention to the assistance levels you use. If you feel you have reached your desired speed, switch to eco mode. Once you feel yourself slowing down again, increase the assistance and help your bike accelerate by pedaling. Remember that high assistance levels drain the battery much faster than low and medium levels. Remember to use the appropriate gears according to your speed and the terrain. This will play a key role in optimizing the distance of your bike rides.

How long does it take to charge the battery?

Our electric bike batteries take up to 4.5 hours to charge when they are almost empty. All batteries can be easily removed and transported, so you can take the battery to your office or home to charge it, while leaving the electric bike in the garage.

What care/maintenance does the battery need?

Batteries are designed to last and can be recharged 600 times or more. Even if you are a frequent cyclist, your battery will serve you for several years before needing replacement. Be sure to follow the instructions in your electric bike manual for attaching and removing it correctly. A damaged battery can be expensive to replace. If you plan not to use your battery for a long period (e.g., in winter), it is preferable to keep it charged between 30% and 60%. Low temperatures can also discharge the battery, so it is advisable to store it indoors.

How to transport your electric bike?

The easiest way to transport an electric bike is to use a bike rack. Since electric bikes are heavier than traditional bikes, they require specific bike racks capable of supporting their weight. These racks are usually equipped with a two-inch hitch that reduces unwanted movement. When transporting your electric bike on a bike rack, it is preferable to remove the battery to reduce its weight. Another method is to fold down the rear seats of your car, remove the front wheel, and place the bike in the back of the vehicle. If you have a spacious car, it may not be necessary to remove the front wheel, as long as the bike can fit in the trunk without excessive compression. Since electric bikes are equipped with sensitive electrical components, it is recommended not to place objects around the bike during transport.

What if my battery runs out or is completely discharged? / Can I use my bike as a classic bike?

If your battery runs out or you completely disable the assistance, you can pedal and use your electric bike as a traditional bike.

Can I take it to a classic bike shop for maintenance?

Electric bikes are more complex than traditional bikes, as they include electrical components and cables. We strongly recommend checking in advance whether the repair shop you are considering has experience with the brand or type of your electric bike. Inexperienced mechanics can sometimes inadvertently damage internal electrical components, which will then be difficult to repair. Once you have found a competent workshop for your electric bike's maintenance, we recommend scheduling annual check-ups and maintenance. If you use your bike almost every day, maintenance at least once a year is recommended.

What is the weight of an electric bike?

Electric bikes are equipped with motors and batteries, which makes them heavier than traditional bikes. On average, an electric bike weighs between 25 and 27 kg (about 55 to 60 pounds), while a classic bike weighs about 14 to 16 kg (about 30 to 35 pounds). Major manufacturers of electric bike drive systems are trying to meet the challenge of reducing component weight. However, lighter versions of batteries and motors generally involve a compromise in power and range.
