Yes, you can ride your Dirwin e-bike as a normal bicycle, however, due to the sturdy aluminum alloy frames on every Dirwin e-bike, most users prefer to use either the pedal assist or throttle when riding.

Yes, all Dirwin e-bikes come with a 24-month warranty, after extending the warranty for another 12 months by filling out our customer registration form after purchase.

Torque Sensor:

How It Works: Measures the force or pressure applied to the pedals. The harder you push, the more assistance the motor provides. It's responsive and delivers power proportional to your effort.


Riding Experience: Feels more natural and smooth, as the power output closely matches the rider's pedaling effort. It’s great for those who want a bike that feels like a traditional bicycle but with extra power.


Ideal For: Riders who want precise control over their power output, such as those navigating varied terrain or using the bike for exercise.

Cadence Sensor:

How It Works: Measures the rotation of the crank (pedal speed) rather than the pressure applied. As long as the pedals are turning, the motor provides a pre-set level of assistance, regardless of how hard you're pedaling.


Riding Experience: Provides a more consistent power output but may feel less responsive.


Ideal For: Riders who prefer a more straightforward system, often at a lower cost, and those using their e-bike for casual commuting or leisurely rides where fine control over power isn’t as critical.
