Surface 604 Quad

POWERFUL 500W MOTOR
Purpose built for top speed Bafang 500W 48V electric motor (Bafang RM G360.500.DC)
Feel the surge of quiet, consistent power distribution at higher speeds - vibration-free.
Geared for performance - we paired all that power with an industry-leading 12mosfet 25A controller, so Quad delivers unmatched torque and speed.

WHISPER SMOOTH TORQUE SENSING PEDAL ASSIST
Because an electric bike is only as good as it’s power distribution.

Quad’s incredibly smooth torque sensor knows how hard you’re pedaling down to the microsecond and matches it with proportionate power.
Custom drop out design delivers whisper smooth torque sensor sensation at any assist level. In fact, you’ll swear it’s as so smooth as a mid-drive motor.
Gone are the days of simple cadence sensors!

REDESIGNED COCKPIT
Now with an extra-large colour LCD display to show all vital information and provide added security.

SURFACE604 Color LCD Display with USB Jack, bigger display: 3.5" for 2024.

Set a passcode and the bike won’t start without it, just like your phone.

LONG RANGE BATTERY
Offering high-capacity battery option:

48V20ah (960wh) 5000mah cell size (Same as in Tesla)

Samsung Cells 21700, Made in Korea, USB Plug, capacity indicator button

Range up to 65 Miles (105 Kms)

Weight: 10.23 LBS (4.65 KG)

*Proprietary design

TIRES WITH STYLE & TOUGHNESS
Impressive aggressive trail capabilities, thanks to its stock Maxxis Rekon+ Skinwall 27.5" x 2.8" 35PSI plus size tires with 3C and EXO casing.

That larger contact patch means more grip, less feedback from small bumps and greater comfort.

Other eMTBs are simply not this sure-footed.
