Dirwin Pioneer Ebike Description

Are you looking for a powerful off-road electric mountain? The Dirwin Pioneer is ready to tackle any rough conditions, from rugged off-trails to gravel paths. It's loaded with a 750W rear hub motor that outputs tons of torque, and the rigid 6061 aluminum alloy frame will transfer that power through the stiff frame to the ground surface.




High-Performance Motor

Sand, gravel, snow... conquer all-terrains with Dirwin Pioneer's high-performance 750W rear-drive motor. It delivers up to 80Nm of torque, which will give you excellent hill-climbing ability. You can ride the Pioneer like a conventional mountain bike, using the 7-speed Shimano drivetrain. But when you need a boost, just turn on the 5-level pedal assist system (PAS) or give the throttle a push, and you'll be flying.

Long-Lasting Battery

Dirwin Pioneer is equipped with a downtube-integrated high-capacity 48V/15Ah lithium battery with LG or BAK cells, giving you an extended range per charge. The battery locks into the frame and can be removed for remote charging (and to protect it against extreme weather conditions).

Color Screen Display

The Pioneer comes with a clear 3.5” TFT display, which has great visibility in all conditions. It features all the information you need to track your ride, including speed, odometer, battery charge level, and more.

Bright 48V LED Headlight

The Luminus Flux headlight has an output of 1100 Lumens and an effective range up to 80 meters. This powerful and bright headlight will keep the road illuminated and make you visible to approaching traffic, cyclists and pedestrians.

Hydraulic Brakes

In tough terrain and fast speeds, you need to be able to trust the braking ability of your bike. That is why the Pioneer is fitted with powerful 180mm hydraulic disc brakes. These provide exceptional precision and stopping power.

Adjustable Handlebar With Easy To Use Controls

The handlebar features all the controls for the gears and power assistance system (PAS) that you need. This includes the assistance level controls, display, half-twist throttle, and Shimano gear shift lever. It's even fitted with a nice bell!

Shimano 7-Speed Gear System

Dirwinuses only the highest Shimano gears systems that give you the reliability and adjustability that you need. In combination with the motor, you can easily set how fast or heavy you want to pedal.

Heavy-Duty 26" x 4" Fat Tires

Fat tires provide a wide area that maintains contact with the ground surface, thereby increasing traction and stability when riding over uneven surfaces. The 26" x 4" fat tires on the Pioneer are highly durable and their knobby treads are designed to operate in extreme riding conditions.

    Absolutely Wonderful!

    My entire family loves this bike. It is well built, sturdy, and handles everything we throw at it. I simply must get another one before spring. Also, the help I received here was great, you will definitely be hearing from me again.

    Really Good Ebikes

    That is great to hear. You are most welcome, we are here when you are ready.


    Love The Power

    I most say this Pioneer lives up to its name. I have nothing but good things to say about this bike. Along with the obvious power, the battery lasts for quite a while. I did a lot of research before buying and all the great things I read about this bike were true. It looks great and is super well built.
