Sport Features

high ground clearance & 

flexible mounting position

X1 PRO fits on 95% of all existing bike frame and you can refer to the FAQs page on how to determine if your frame fits.

X1 PRO is designed to be used in extreme terrain which means that a high ground clearance is needed. With traditional bottom bracket mounted motors, the ground clearance is sacrificed and the motor is usually at the lowest point which is closest to the ground. However, the X1 PRO is uniquely designed to optimize ground clearance.

With X1 PRO unique design, it is able to install high up from the ground, especially in the modern bike frame with a curved downtube. You can also choose to install the X1 PRO within the triangular frame (need to mount the controller separately with this option), making the X1 PRO the best machine for E-MTB conversion.

There are also three chainring options so you can achieve same ground clearance as you get from your mountain bike before conversion. (Please refer to the FAQ on how to choose your chainring options.)

The Gen 2 X1 PRO has 2 pressfit versions which have a spot on chainline. Pressfit frames are common in modern mountain bikes. It is typically very difficult to convert pressfit bikes into e-bikes due to the offset chainline. The BB92 & BB109 bottom bracket versions are designed to be a direct fit with a perfect chainline of 51mm and 59.5mm respectively. 

When designing the X1 PRO, we considered the modern frame and geometry. X1 PRO and X1 Stealth are unique for this reason.

instantly switch between modes

The controller options of X1 PRO allows you to set 2 modes.

To switch between modes instantly, long press the power button on your display (either APT 500c or 750c). We have 2 modes set before shipment namely Street Mode and Race Mode.

In each mode, you can customize the settings via the app, including the maximum power, throttle response rate, PAS level, PAS on/off, etc. 

We have the most comprehensive programming ability with the new app and controller. Simplified yet comprehensive for all functions needed making it is suitable for daily commute and trail riding.

Torque sensor and throttle equipped

X1 PRO comes with both torque sensor and throttle.


Torque sensor is used in pedal assist mode. The torque sensor measures how hard and how fast you pedal, and calculate how much power the motor should output correspondingly. You can read your own power via mobile app to monitor your exercise rate. You can also customize the proportion of the motor power output in case you want to change the ratio of assist.

There are 3 throttle options: thumb, half-twist, and full throttle.

light weight and unlimited power


The maximum power of X1 PRO is measured at 5kW at 72V, and the motor system is highly efficient. The efficiency gives a much longer range and thus you can carry a much smaller batteries.

At 5kW and throttle mode you will be able to ride your e-bike like a strong electric dirt bike. The small form factor still enables extreme power and torque output. If you use a strong downhill frame for X1 PRO, it will be a very capable offroad machine.

Most importantly, the e-bike after conversion still looks like a typical e-MTB which allows you to enter most of the trails.
