== 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.

== Controller configuration ==
[[Image:matex_color_display_china.png|right|450px]][[Image:matex_ukriver_ukc1_settings.jpg|right|450px]][[Image:matex_key-disp_kd51c-d_settings.png|right|180px]]
Enter the settings by double-tapping the "M"-button on Ukriver display or "Power"-button on the Bafang display, or hold both "+" and "-"-buttons for two seconds for the black/white Key-Disp display. 

All of these settings are available on the Bafang color display but only a limited set is available on the Ukriver color display and Key-Disp black/white display.

'''Optimal controller settings:'''

'''''Display settings:'''''
* Language: English
* System: Imperial - for km/h
* Brightness: 5
* 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, Bafang displays 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 instantaneous 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:
** Ukriver display: 1801
** Bafang display: 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 (Bafang) 52 km/h (Ukriver) 39 km/h (Key-Disp)
*** 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: 18A (48x18=864Watt)
** Boost performance: 20A (48x20=960Watt)
** Max. controller current: 25A (48x25=1200Watt) - short bursts only, could overheat motor coil - Bafang 50A max. value, Ukriver 30A max. value
* Poles in motor: 1 - magnetic poles inside the motor, used to calculate the speed indicator
* Start poles: 1 - number of poles (speed sensor) needed to be detected by controller before starting the motor
* Clockwise start: Yes - speed sensor turn direction, "Yes" means forward looking from right-side of bike
* Throttle 6km: No - "Yes" turns walk-mode ON while twisting throttle
* Throttle level: No - "Yes" limits the top throttle speed to match 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

== Configuration presets ==

A few presets depending on your preferences. Note that there is no way to turn off the motor cut-off after you stop pedaling, use the brake levers instead to cut the motor.

=== Default ===
The default riding configuration is meant to conform to the EU and regional speed regulations. 

* Speed limit: 
** 250: 25km/h
** 750S: 32km/h
* Current limit:
** 250: 10A (546W peak) / 15A (819W peak)
** 750S: 18A (983W peak)
* Assist levels: 9
** Level while riding: 3 to 5

=== Smooth and quick ===
For gradual acceleration and great top speed. Suitable for stop-and-go city riding and road riding/commuting. Unsuitable for hilly rides, as the top speed will be low because of the current limit. Using stock 53T front chainring.

* Speed limit
** 250: 35km/h
** 750S: 35km/h
* Current limit:
** 250: 12A (655W peak)
** 750S: 12A (655W peak)
* Assist levels: 10 - "Ludacris" turbo-mode enabled, but not needed
** Level while riding: 2 (10 km/h) to 7 (35 km/h)

=== Smooth and rapid (new chainring) ===
Same gradual acceleration but higher speeds when using the '''58T chainring upgrade part''' for improved pedaling.

** Level while riding: 2 (10 km/h) to 7 (35 km/h)

=== Responsive and fast ===

** 250: 52km/h
** 750S: 52km/h
* Current limit:
** 250: 18A (983W peak) - motor max.

* For daily use, assist level 5 or 6 is a good combination of speed and battery capacity conservation
* View current, average and max. speed, press "M"/"i"-button multiple times
* View ODO, trip time and trip distance, press "Power"-button multiple times
* Enter configuration menu, double tap "M"/"i"-button
* Walk assistant up hills, set assist level 0 and hold "-" for "P" to appear on the display and it will begin to roll, release to stop
* Charge via the USB-port at 5V 0.5A (2.5W), press and hold the "M"/"i"-button for a USB-icon to appear, stays on until power-off
* Turn on the lights, press and hold "+"-button, same to turn off
* Reset average speed, max speed, trip distance and trip time, press "+" and "-" at the same time
* On steep hill climbs or starts, it is curial to assist the motor as subjecting the motor to unnecessary load can cause the controller to blow/overheat
* Ranges from 54.6V when full, down to 41.6V when empty, but always charge at around, or before, 44V
* For the smoothest ride, set current to 12A and max. speed to 52km/h
* Re-pressurize the tires every few weeks, as fat bike tubes naturally deflates faster

'''Initial setup'''
# Insert the seat stem and adjust the lock bracket
# Mount the handlebar and lock it in place
# Install the front wheel and insert the lever
# Screw in place the pedals
# Put the reflectors on the wheels
# Install the fenders and rear rack (if acquired)
# Attach the front lights and remove the left handle bar grip to install the horn/turning-inducator (if acquired)
# Adjust to get a flat saddle
# Adjust the handle bar height and level with the lever
# Inflate the tires to 20-25 psi, 1.4 to 1.6 bar - check often
# Charge the battery by plugging the wall socket first, then charger plug
# Press and hold power button and configure the bike computer, double tap "M"-button
| valign="top" width="25%" |
'''Charging procedure'''
# Park bike securely
# Turn off bike by holding power button on left handle
# Either take out the battery, or leave it in the bike
# Plug in charger into wall socket/mains
# Insert the other charger lead into the battery
# Wait for the charge to complete, max. 4h for 4A charger, max. 8h for 2A charger
# Unplug lead from bike then from wall socket
# Power on bike by holding the power button
# Verify battery state of charge by looking at the battery indicator on the display
| valign="top" width="25%" |
'''Connect front and rear lights, horn'''
# Open the harness under the frame where the MATE-logo is placed
# Find the yellow 3-pin connector for the integrated front-light/horn
# Open the controller compartment to find the black 6-pin connector for the rear-light/turning-light/horn-switch
# The 6-pin black cable connects to the supplied Y-split cable where the rear-light/turning-light is connected to one end, and the horn-switch to the other
# Mount the front light, rear light, and handlebar switch accordingly, route the new cables inside the cable wrap on the bike
| valign="top" width="25%" |
'''Tighten and secure bike'''
# Tighten the two kick-stand screws
# Fasten the steering folding-stem screw to the headset just enough so it is hard to fold the handle in place
# Inside the folding-stem, tighten the 12mm top-screw
# Secure the handlebar height clamp-screw so it is hard to unfold the handle by accident
# Go over all the screws on the handlebar for the brake-levers, display and hand-grips
# Adjust the seat-post clamp-screw for a tight secure fit
# 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
# Tighten the screws holding the brake calibers to the frame

| valign="top" width="25%" |
'''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
| valign="top" width="25%" |
'''Brake sensor sensitivity'''
# If the brake handle keeps cutting off the motor, decrease the sensor sensitivity - essentially moving the reed-sensor further away from the built-in magnet (also related to brake error 25)
# On the under-side of the brake handle, loosen the small 2mm hex bolt slightly
# Adjust the 7mm nut with a wrench, do a half-turn at a time and try the bike
## Turn it counter-clockwise/out to decrease the sensitivity
## Turn it clockwise to increase the sensitivity
# Tighten the 2mm hex bolt again
| valign="top" width="25%" |
'''Modifying front suspension fork'''
# A normal fat bike 20- or 26-inch front suspension will fit, only the normal procedure of shortening of the stem is required
# Full instructions available on the following PDF
# [[Media:mate_x_front_fork_suspension_modification_alex_rev1.pdf|Modifying front suspension fork to fit MATE X]]
| valign="top" width="25%" |
'''Fixing throttle cut-off'''
# When the throttle keeps cutting-off after 5-10% push, adjust the position of the entire throttle unit
# Unscrew the small hex screw on the underside
# Rotate the throttle towards you to get space from the interference source (possibly brake sensor)
# Re-tighten the handlebar screw

{| border="0" cellspacing="0" cellpadding="1" width="75%"
| valign="top" width="25%" |
'''Mounting wheel reflectors'''
# The reflectors are mounted inside the spokes using the plastic parts and supplied screws
# Gather the right parts[[Image:mate_x_reflectors1.jpg|180px]]
# Mount them as shown using a screwdriver[[Image:mate_x_reflectors2.jpg|180px]]
| valign="top" width="25%" |
'''Reduce chain rattling'''
# Add a 10-15mm adhesive foam strip (for windows/doors) to the frame where the chain hits the top surface
#Remove the protective side[[Image:mate_x_chainfoam1.jpg|180px]]
#Apply to the frame[[Image:mate_x_chainfoam2.jpg|180px]]
| valign="top" width="25%" |
'''Reduce kick-stand rattling'''
# Add a 10-15mm adhesive foam strip (for windows/doors) to the frame where the kick-stnad hits the stop-position
