Tires/Wheels Atom Alpha has tire sizes of 90/90-10 rubber tires with inner tubes and a rim liner. The tube size for both the front and rear tires is 10″ x 4.00″. The tires are designed for durability and safety for regular scooter activities. However, tires must be checked before each use for proper inflation and condition. Proper inflation, good maintenance, and quick replacement will help ensure that the operational characteristics of your Atom Alpha will be maintained and dangerous conditions avoided. Tires must be inflated using a pump with a Schrader valve tip with a recommended pressure between 18 and 25 psi (1.24 – 1.72 bar). Check the condition of the tires and rims for damage, cracks or deformation. The minimal tightening torque of the wheel nuts is 25ft/lb (33.89 N m). It is essential that the proper air pressure is maintained in the tires all the time. Do not under-inflate or over-inflate your tires. Low pressure can cause loss of control and tires that are too inflated can burst. Failure to maintain proper air pressure rating indicated in the handbook may at any time result in tire and/or wheel failure. Inflate your tires from a regulated air source with an available manometer. Inflating your tires with an unregulated air source could over-inflate them, resulting in an exploded tire. When tire wear becomes obvious or a hole in the tire is found, you must replace the tires and / or tubes before using Atom Alpha, otherwise injury to operators and / or damage to your Atom Alpha could occur. In addition to proper inflation, correct wheel alignment helps to decrease tire wear. If you find a tire is worn unevenly, have a professional motorcycle mechanic check the wheel Alignment. Brakes Brakes are an integral part of the operation of your Atom Alpha and must be properly maintained, adjusted, and replaced. If any of the below is not within your skill set we recommend taking your Atom Alpha to an E-bike specialist or professional motorcycle mechanic. Mechanical brake lines require maintenance not only on the pads and rotors but also on the brake cables. The wear of the pads on a mechanical disc brake can be regulated by unscrewing the cable tension knob. There is a complimentary adjustment of the inner pad which can be tightened closer or removed from the disc by screwing it in or out with a 5 mm Allen key. To ensure maximum service life of the brake components, avoid contamination of the pads and the disc by greasy substances. Regularly check the condition of your cables, ducts or harness and the wear of your pads. Some discs are only compatible with “resin” pads. Do not use a metal pad with discs marked “Resin”. For better ergonomics and safety, we advise you to adjust the brake levers in a position that places it as a natural extension of the user’s arms. If you have any questions or concerns, please contact Atom Alpha. New Brake Pad & Rotor Ben-in Process Any time you replace your brake pads, rotors, or both, it is important they are properly bedded for optimal performance. To bed your brakes properly after replace- ment, accelerate your Atom Alpha up to 30 km/h and then engage your brakes to bring Atom Alpha to a near stop, and then repeat the process up to 8-10 times. This process allows your pads to wear evenly as well as remove surface glaze and contamination from installation. Replacing the Pads When pads are worn, make sure to adjust both clearances between the rotor and pad so that they are equal and balanced. If only one side isadjusted it will cause braking failure. Pads and pad holders are held in place by a cotter pin on the caliper. To remove the pads and pad holder, straighten the cotter pin and remove, then gently push out the pads and holder. This may be easier to achieve by using an Allen wrench. Once free of the caliper, the pads may be easily removed from the pad holder. Battery The battery is the most important component of your Atom Alpha. Following a few simple rules, you can optimize its life: Do not store a discharged battery. It could go into deep discharge which will reduce its life. Make it a habit to recharge at the end of each ride, so your Atom Alpha will always be ready to go again. Observe operating conditions between 4°C – 30°C. Do not leave your battery exposed to high temperatures or direct sunlight for long periods of time (for example, on the back of a car in direct sunlight). Do not dispose of the battery in your trash. There are proper disposal methods for lithium-ion batteries. Please check your local waste management regulations. Do not open the battery. There is a risk of short circuit. Opening the battery will void the warranty. Protect the battery against mechanical damage, heat (in case of prolonged exposure to sunlight), fire, and immersion in water. There is a risk of explosion. In case of damage and improper use of the battery, vapors may emanate. Keep children away from the battery To charge the battery, use only the original charger or charger approved by the manufacturer. Disconnect the charger from the power supply when charging is complete. Range The maximum range of a full charge depends on many variables such as: age of battery, type of terrain and incline, rider weight, speed, outside temperature, driving style or tire pressure. Conditions that affect your battery’s range: Temperature : Extreme cold and heat can affect the battery’s capacity. Total Number of Charge Cycles : As the battery ages, total capacity can decrease. The battery has a total of 1,000 full cycles when it’s new. Wind : Riding into a strong headwind can decrease range. Road Conditions : Excessively rough or hilly terrain requires the consumption of more power. Load : Carrying extra cargo on Atom Alpha or in a backpack will use more energy. Rider Weight : Please observe the max weight of 100 kg. Poor Maintenance : Under-inflated tires, mal-adjusted brakes, can decrease range. Acceleration : Repeated acceleration from a standing start. Tips for Maximizing Range Charge the battery at a comfortable temperature range between 18.3°C – 23.9°C. Lithium-ion batteries have no chemical memory, and it is not necessary to discharge the battery completely for the best performance. Charging a partially full battery will have no negative effect. Maintain proper tire pressure. Operating temperatures between 4°C – 30°C will significantly increase range. Caution Never charge the battery in a flammable environment. For safety reasons, the charger and the battery must be placed on a dry, non-flammable surface. Never charge or use a defective battery. Never send a battery by postal mail by yourself! A battery is in the category of hazardous/dangerous goods and requires certification to send by mail. Doing so without proper certification is punishable by law. Immediately remove the battery from Atom Alpha if you notice damage to the electrical system and visit your local E-bike Specialist for inspection or contact Atom Alpha directly. Any lack of professional expertise may cause damage or serious injury. Seat It is not possible to adjust the seat height of the Atom Alpha. It is fixed to the frame with bolts. For maintenance, use a cloth and water with mild soap to clean. Avoid leaving the chair in the sun too long, as the fabric can be damaged by the sun’s UV rays. Avoid wearing clothing that could puncture or tear the chair. Alpha Atoms are subject to wear and tear, like all mechanical parts. Materials and parts react differently to wear and abrasion. If the intended life of a part is exceeded, it is possible that it will suddenly fail, which is a certain danger to motorists. Any type of crack, scratch, or discoloration in a highly stressed area indicates maximum wear of a part. Therefore, it must be replaced immediately. It is important to use genuine parts that are properly specified for safety-critical components during the replacement of worn parts.
