Our verdict

Strong specs and a comfortable ride for the price when it works, but multiple owners hit early hardware faults, so factor in some post-purchase troubleshooting risk.

Overview

A 26x4 fat tire electric bike from Jasion built around an 1800W peak motor and 864Wh removable battery, aimed at long-range commuting and adventure riding with hydraulic brakes and front suspension.

The bike itself draws solid marks for comfort and speed, but reliability and support are the recurring sore points in owner feedback: controller failures, sensor faults and a wrong-color shipment all show up across a small review set. Weigh that against the strong on-paper range and torque before buying.

  • 1800W peak motor, 85 N.m torque
  • 48V 18Ah battery, up to 80 mile range
  • 26 inch x 4 inch fat tires, 400 lb capacity
  • Dual hydraulic disc brakes, 7-speed Shimano drivetrain

Who it's for

Riders prioritizing long range and torque who are willing to troubleshoot occasional hardware faults or deal with customer support. Less suited to buyers who want a trouble-free unboxing experience.

Pros and cons

Pros
  • Comfortable ride and strong acceleration when hardware works
  • Good value cited relative to price after 20 days of regular use
  • 400 lb load capacity and 26x4 fat tires for stability

Performance notes

The 48V 18Ah battery and 1800W peak motor are built for sustained torque on hills and long commutes, and owners who had no hardware faults describe the ride as comfortable and capable at highway-adjacent speeds; the issue reported repeatedly is component reliability rather than the ride quality itself.
