Mate x folding ebike overview.jpg

The MATE X is a folding electric bicycle. It was made possible in June 2017 by Christian Adel Michael and Julie Kronstrøm from Copenhagen, Denmark. This was the second Indiegogo campaign they successfully funded. The first campaign was the original MATE folding ebike.

  • Campaign started: 1st May 2018
  • Campaign published: 16th July 2018
  • Campaign concluded: 23rd July 2018 15th August 2018 14th September 2018 22nd September 2018 28nd September 2018 26th April 2019
  • First big shipment: May/June 2019, majority July/August 2019, last shipment end of September 2019


Models

There are three different models of the MATE X, the 250, 250+ and 750. A set of accessories can also be added to the bike when placing an order.

There are two set of different bikes, due to the new APAC enforcement meaning that the bikes heading for EU (and all later orders) had to be manufactured outside of China. That meant that the majority of the bike components had to be made or sourced in Taiwan instead, making it a different bike than what was promised initial on Indiegogo and after the first batch of orders (all orders delivered after June 2019). The Chinese manufactured bikes made up until then were shipped to non-APAC countries.

Tighten and secure bike

  1. Tighten the two kick-stand screws
  2. Fasten the steering folding-stem screw to the headset just enough so it is hard to fold the handle in place
  3. Adjust the seat-post clamp-screw for a tight secure fit
  4. Secure the handlebar height clamp-screw so it is hard to unfold the handle by accident
  5. Adjust the main frame lock handle screw located on the bottom hinge when the lock is open, adjust from bottom side for a secure lock

Remove tire from rim Gear down to the 8th-gear Unplug the rear wheel-cable Unscrew the kick-stand Remove silver bolts and washer holding the axel Bend back the rear derailleur Then lift the wheel out Deflate tire and use a plastic spudger to lift the tire bead off Push in the valve and carefully remove inner tube Lift the tire off the rim

Controller configuration

Enter the settings by double-tapping the M-button on the left handlebar.

Optimal controller settings:

Display settings:

  • Language: English
  • System: Imperial - for km/h
  • Brightness: IIII
  • Auto off: 5 minutes - power down the bike after idle period
  • Scenes: Digital - the theme of the display layout
  • Battery indicator: Voltage - easier to determine battery state, percentage only in 20%/five steps
    • Ranges from 54.6V when full, down to 41.6V when empty, but always charge at around, or before, 44V
  • Power indicator: Digital - shows instantanous wattage
  • Clock: Set the date and time
  • Start password: Prompted for your password when you power on the bike

Basic settings:

  • System voltage: 48V - the type of battery drive system used
  • Wheel size: 24-inch - even though the real wheel size is 20-inch, gives a more accurate speed indication on the display, can also be input in measured cm
  • USB port: On - USB-port beneath the display
  • Information: shows max./avg. speeds and ODO meter

Advanced settings:

Go to the "Advanced settings" menu-option and enter the following pin code.

  • Enter pin code:
    • China bikes: 1801 - Bafang display
    • Taiwan bikes: 1919
  • Speed limit - max. speed before controller/motor stops assisting
    • 250: 25 km/h default/EU
    • 750S: 32 km/h default
    • Max. value: 99 km/h
      • Unlocks Ludacris mode for ~35mph / ~56kmh max. real speed - does not void warranty anymore
      • Unlocks hidden assistant level 10 - turbo mode
  • Current limit - maximum current through controller during acceleration and climbing steep gradients
    • Default: 15A (48x15=720Watt)
    • Boost performance: 20A (48x20=960Watt)
    • Max. value: 25A (48x25=1200Watt) - short bursts only, could overheat motor coil
  • Poles in motor: 1 - magnetic poles inside the motor
  • Start poles: 2 - number of poles (speed sensor) needed to be detected by controller before starting motor
  • Clockwise start: Yes - speed sensor turn direction, "Yes" means forward looking from right-side of bike
  • Throttle 6km: No - "Yes" turns on walk-mode after twisting throttle
  • Throttle level: No - "Yes" limits the top throttle speed according to the assist level
  • Start mode: ECO - Power/ECO/Standard, sets the maximum current curve when starting riding/accelerating, limited current with ECO
  • Assist levels: 9 - 3/5/9, how gradual/number of steps the levels should be
  • Assist setting: Further adjust each assist level, all default to 0

Third-party upgrade ideas

  • LED-light strips underneath frame
  • Strong head-beams
  • GPS tracker
  • Folding magnet lock
  • Storage bag/box
  • Custom front and rear lights - light comparison
