When it comes to commuting via bike, too much riding will leave us exhausted and sweaty. So we designed Qualibike. Firstly a great bike, then a pedal assistant e-bike, and to top it off, we also added a cruise control system.

Folding Frame

Aluminum Alloy Grade 6061 frame and front fork, totally new design, passed all vibration tests, light but strong enough to hold up to 220 lbs. It can also be folded within 3 steps so it doesn't occupy too much of your room or to easily fit in your trunk.


Customized 350W high speed geared brushless motor, less than 5 lbs but with 40 Nm torque, so you can go uphill over 18°. It's so powerful that you can tackle hills without breaking much of a sweat. With a built-in clutch, you'll never feel any magnetic resistance when riding without any power it's a pure, comfortable bike.


To make Qualibike neat and unique, we created a seat-post lithium battery as our power system. Most people won't recognize it's an e-bike at first glance. And BMS system is also important. It keeps your battery safe from over-charging, over the outlet and overheating. Also, BMS manages all the cells to work more efficiently to offer you a longer range. The seat-post battery is removable so you can either charge it in the bike or separately in your room.

Disc Brake

Front and rear disc break keep you safe from any emergency with a break distance within 3 meters. Also, ebike lever is another safety feature on this bike shutting down the power system right away if you apply the breaks.

PAS Riding System

The multi-function LCD display, 12 points sensor, and FOC controller together combine the PAS system. You can either ride at pedals mode, in cruise control mode without pedaling or pure bike mode if you need. The sensor could detect every intention precisely. Once you ride a Qualibike, you will fall in love with it.
