Surface 604 Electric: Quad - Electric Mountain Bike
POWERFUL 500W MOTOR
Brand new at Bike Attack Electric. An electric mountain bike with 27.5" tires build like a dirt jumper for top speeds with a 500W 48V electric motor. 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.
Watch out for other riders as you zip pass them.
WHISPER SMOOTH TORQUE SENSING PEDAL ASSIST
Because an electric bike is only as good as it’s power distribution.
Quad incredibly smooth torque sensor knows how hard you’re pedalling down to the microsecond and matches it with aproportionate power.
Gone are the days of simple cadence sensors!
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.
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.
