Frequently asked questions
What is the difference between rated and peak power?
The supplier lists 250W rated output and 750W peak output. Peak output is not the continuous motor rating.
Which battery configuration does it use?
48V 35Ah + 30Ah lithium-ion; 65Ah total, 3120Wh nominal combined. Check the exact model and electrical connections before purchasing replacements.
How long does charging take?
Approximately 7–8 hours. Use only the compatible charger and follow the supplied battery instructions; charging time varies with the starting charge and conditions.
What tyres are fitted?
The model-specific table specifies 20 × 4.0-inch Kenda tyres. Check the sidewall, pressure guidance and exact wheel fit before replacing tyres or tubes.
What braking system does it use?
Hydraulic brakes are listed. Inspect both brakes before each ride and follow the supplied instructions for servicing and compatible replacement parts.
What display is fitted?
The supplier specifies a TW35H display with app and NFC functions. Confirm the delivered display version before buying replacement electronics or following setup instructions.
Is 65Ah one battery?
No. The model-specific table lists two 48V packs rated at 35Ah and 30Ah. Their combined nominal capacity is 65Ah or 3120Wh. Use only the compatible chargers and follow the supplied instructions for each battery.
Is the bike waterproof?
No. The supplier lists IP54, which does not allow immersion or pressure washing. Keep the battery connectors and charging equipment dry.
What are the weight and carrying limits?
The supplier lists 54kg net weight and a 120kg maximum load. A cargo-style frame or rear rack does not establish passenger seating approval or a separate rack capacity.
Is it approved for public-road use everywhere?
No. Motor rating and speed alone do not establish legal classification in every country. Check the exact delivered configuration and local rules before use.
