Summary of Reviews

9 reasons to buy

Experts praise the ride comfort over broken pavement, dirt paths, and light off-road terrain.
The Cyrusher Flex has both torque and cadence sensors. Riders can switch between them by triple-pressing the power button.
Testers enjoy the smooth and natural-feeling pedal assist in torque-sensing mode.
This bike comes with a headlight, taillights with brake activation, and a USB-A charging port in the display.
The throttle is responsive and provides quick acceleration.
In testing, the Flex handles steep inclines on throttle power alone.
A 215lb reviewer gets 28 miles of range over mixed terrain using mostly the throttle.
The Tektro hydraulic disc brakes provide good stopping power in testing.
The adjustable stem allows quick modifications to fit.

9 reasons not to buy

A reviewer says the Flex is unsuitable for proper mountain bike trails, despite Cyrusher's claims.
This bike is rated for riders 5’7” and above, but a 5'10" tester needs the saddle in its highest position in order to pedal somewhat comfortably.
At 68lb, the Flex is very heavy for a bike marketed as an electric mountain bike.
One test bike suffers from a squeaking rear brake even after adjustment.
When unlocked, the throttle reaches a max speed of 30mph, exceeding legal e-bike limits.
The small display is difficult to read in sunlight.
Two testers find the motor noisy.
The 2A charger yields lengthy charging times.
A reviewer says the assembly instructions for fitting the front wheel are incorrect.

Bottom line

Calling Cyrusher's Flex a mountain bike is a stretch. This full-suspension hybrid e-bike can handle dirt paths and light off-road terrain, and testers praise the performance at this price point, especially the switchable torque and cadence sensors, responsive throttle, smooth assistance, climbing power, and range. However, the high weight and cheap suspension mean it's not suitable for actual mountain bike riding. The narrow height range also severely limits who can ride this bike comfortably. Nevertheless, for those who fit, testers deem the Cyrusher Flex a good option for mixed-terrain riding.
