U9 Electric Bike FAQS
The U9 features a step-through frame that makes it easier to get on and off without having to lift your leg over a high top tube. This makes it particularly suitable for frequent stops, everyday commuting and riders who value easier mounting and dismounting. The U9 is recommended for riders approximately 5'3" to 6'5" tall, making it suitable for a wide range of adults.
If easy access is one of your priorities, you can also explore VITILAN’s Step Through Electric Bike range.
The U9 uses a brushless hub motor with approximately 65 Nm of torque, providing reliable assistance for daily commuting, pulling away and tackling gentle hills.
Its torque sensor adjusts motor assistance to match your pedalling effort, making the ride feel smooth and natural.
The U9 is fitted with a 48V 15Ah LG battery, providing approximately 720Wh of capacity.
According to the product specifications, the U9 can provide up to around 80 km of range with pedal assist and up to around 50 km when using the throttle only. Actual range may vary depending on the assistance level, rider weight, gradients, weather conditions, tyre pressure and riding speed.
For daily commuting and weekend leisure rides, this range can help reduce the need for frequent charging.
Yes. The U9 features a folding frame design that helps reduce the amount of space it takes up when stored at home, in a garage or in other limited storage areas.
The folding design is combined with a step-through frame, giving riders both easier access and more convenient storage. This makes the U9 a practical option for riders who value comfort as well as everyday convenience.
If compact storage is an important part of your buying decision, you can also explore VITILAN’s Folding Electric Bike range.
The U9 uses a torque sensor to detect how much pressure the rider applies to the pedals and adjusts motor assistance accordingly.
Compared with a cadence sensor, which mainly detects pedalling movement, a torque sensor can provide assistance that responds more closely to how hard you are actually pedalling. For example, when you pedal harder or begin climbing, the system can provide more support, while lighter pedalling on flatter roads results in gentler assistance.
This creates a more natural riding experience while still giving you the benefit of electric assistance.
The U9’s 48V 15Ah battery takes approximately 4 to 6 hours to charge.
According to the product specifications, charging from 0% to around 80% typically takes about 4 hours, while a full charge takes approximately 6 hours. Actual charging time may vary depending on the remaining battery level, charging conditions and battery status.
Yes. The U9 is supplied with a default maximum speed setting of 25 km/h, in line with European electric bike speed requirements and suitable for everyday commuting and urban riding.
