Frequently Asked Questions - Cosmo 2.0 Magnum
How long does the battery last on a single charge?
The 48V 14Ah battery provides a range of up to 50 miles (80 km) in Eco mode, depending on terrain, rider weight, and riding style.
Can I ride the bike without using the electric assist?
Yes, you can ride it as a conventional bike with the motor off. However, the extra weight (62 lbs) makes it harder to pedal without assist.
How do I charge the battery? Should I remove it from the bike?
The battery is removable for convenient charging. Use the included charger; a full charge takes 4-6 hours. It's best to charge at room temperature.
What is the top speed?
The bike can reach 20 mph (32 km/h) using throttle-only and up to 28 mph (45 km/h) with pedal assist, compliant with Class 3 e-bike regulations.
Is the bike waterproof? Can I ride in the rain?
The bike is water-resistant for light rain, but avoid submerging or high-pressure washing. Dry the bike after wet rides to prevent corrosion.
How do I adjust the brakes and gears?
Consult the manual for specific adjustment steps. Generally, use a 5mm Allen key to adjust brake calipers and a phillips screwdriver for derailleur tension. If unsure, visit a professional.
What maintenance does the bike require?
Regular maintenance includes lubricating the chain every 100 miles, checking tire pressure (40-50 psi), and inspecting brake pads for wear. Store the battery partially charged if not used for long.
Can I upgrade the battery or motor?
The battery is designed to be easily replaceable with a compatible Magnum battery. Upgrading the motor is not recommended due to controller compatibility and safety.
How do I pair the bike with the display?
The display is pre-paired from the factory. If you need to reset, turn on the bike, press and hold the power button until the display shows a pairing mode, then wait for connection.
What is the weight limit for the bike?
The maximum load capacity is 300 lbs (136 kg), including rider and cargo. Exceeding this may damage the frame or cause safety issues.
