    Dual Battery Parallel Module - brought to you by Bicycle Motor Works
    20-72v, 120 amps
    Now you can safely run two battery packs in parallel.  Double your current, double your range, double you fun!
    Size of module: 63mm x 78mm x 25mm
    If you don’t already know, without a protective circuit there are many dangers to using two battery packs in parallel in order to increase your range.  This smart module eliminates those dangers, and it allows you to easily and safely combine two packs of the same nominal voltage.
    When the packs are at the same voltage level, the module will draw equally from each pack to power your motor.  If the packs are at different voltage levels, the module will draw on the higher voltage pack until the voltage levels become equal.  At that point both packs will be combined to power your motor.
    Use two battery packs of equal nominal voltage. You can combine two packs of different capacity (ie: 10ah + 15ah)

    • RATED POWER: 5000W
    • PEAK TORQUE: 250N.m./250N.m.
    • COMPATIBLE: 36V to 72V
    • CHAINRING OPTIONS: 32T & 38T (30-52T with BCD104)
    • BOTTOM BRACKET OPTIONS: 68-120MM
    High Ground Clearance: X1 PRO is designed to be used in extreme terrain. Thus a high ground clearance is needed. With traditional BB mounted motor like BBS series, the ground clearance is sacrificed and the motor is usually at the lowest point which is closest to the ground. ​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.
    Fits All Common Bottom Brackets: The Gen 4 X1 PRO fits all standard and fat bike bottom brackets from 68mm to 120mm. It has a special BB92 Version which has a spot on chainline. BB92 Pressfit frame is common in modern mountain bike frame. It is typically very difficult to convert BB92 bike into electric due to the offset chainline. The BB92 is designed to be direct fit and with a perfect chainline of 51mm.
    CYC Ride Control:
    Pair the CYC Ride Control mobile app with the X-Controller Series and it gives you the ultimate freedom to ride your way. Via Bluetooth connectivity, we have ensured that your ebike experience is now more integrated than ever.
    Torque & Cadence Sensors: X1 PRO comes with a Torque sensor that is used in pedal assist mode. The torque sensor measures how hard and cadence measures how fast you pedal. These are collected and processed together by the controller to provide natural feeling of pedal assist and calculates how much power the motor should output correspondingly. A big bonus is that it also measures and records your own power via the mobile app so you can 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. EMTB mode when using comparable power levels.
    Warning: This beast is for the thrill seeker enthusiast. Read full description before you accept more power into your life.
