    A 720Wh battery and SBC Carbon fork makes the FAT Comp a BIC eBike!

    The S-Electro FAT Comp features a complex hydro formed alloy frame with a 720Wh internal battery located in the downtube. The FAT Comp is designed around all-day comfort geometry and compatible with gigantic 4.8" FAT tyres. This makes the S-Electro FAT Comp a very capable bike that loves a challenge, and with the high capacity battery, you could venture vast distances assisted, without the need for recharge on the way. The battery can be charged in-place in the frame, or where power outlets aren't close by, the battery can easily be removed.

    Hydro formed double butted integrated alloy frame

    FAT Comp features a double butted hydro-formed alloy frame with integrated motor mount, smooth weld top junctions and internal battery. This means that the frame can have thinner sidewalls, complex shapes and curves that makes it stronger and lighter than comparative alloy frames with regular tubing. Hydro forming is the process of forcing tubing into a negative mold with internal pressurised oil and or water.

    Drive system, power and display.

    S-Electro FAT Comp is designed around a Shimano EP8 250W motor with integrated torque sensor. This motor is paired to a decent sized 720Wh internal battery giving the FAT a solid range of assisted exploring. A smart control LED button located in the top tube makes switching modes intuitive and easy to do on the fly, also indicating battery levels. An on-bar Led display is easy to use and shows all rider info for the electric system.

    Carbon Rigid Fat fork

    FAT Comp is fitted with an SBC carbon rigid FAT fork. Lightweight, stiff, and technologically advanced, the Carbon fork offers comfort over alloy forks.

     S-Electro Fat Comp motor mount

    3D forged motor mount

    The integrated motor mount used on the FAT is 3D forged. This process makes intricate parts, relatively light and super strong. The process uses a hydraulic press, heat and molds to form metal into the required 3D shape.

    Smart control LED button

    The intuitive LED button makes switching between modes easier and more intuitive for users, as well as indicating battery level in colour.

     S-Electro Fat Comp fat wheels

    FAT tyre compatibility

    FAT Comp is designed to accommodate tyres of up to 26" x 4.8". Higher volume tyres means more grip and more comfort. These massive tyres also floats over snow or sand with ease.

     S-Electro Fat Comp geometry


    Geometry on the S-Electro FAT Comp is designed to give efficient power delivery to the wheels, promoting comfort for long days out on the bike and the slacker head angle improves handling. This makes the FAT Comp the ideal adventure or touring companion. The frame also has a low standover, making it great for both male and female riders.

    Short Chainstays

    Shorter chainstays means nimble handling, and with the centralized weight of the electric drive system, the compact rear end provides a more balanced ride feel.

    Integrated motor cover

    The frame is finished with a protective motor cover. This protects the motor from impact damage, and also finishes the bike really well.

     S-Electro Fat Comp dropper post compatable

    Dropper post compatibility

    The bike is internal routed dropper post compatible and easy to set up. Dropper posts increase riding clearance on technical sections, but could also improve your experience commuting or touring, making mounting and dismounting easier, and stops or traffic light waits less cumbersome.
