Overview
The X-koala G26 is a 26-inch fat tire mountain e-bike built around a motor listed at 1200W peak (1500W in the title) with a 28 mph top speed and a removable 36V 13Ah battery. It ships about 90 percent pre-assembled with a 7-speed drivetrain and dual suspension.
This model draws a wide split in owner experience.
- 1200W peak motor, 28 mph top speed
- 36V 13Ah removable battery
- 7-speed gearing with 5-level pedal assist
- Front and rear suspension with dual disc brakes
Who it's for
Not a good fit for anyone who wants a bike that works reliably straight out of the box without any adjustment.
Pros and cons
- Reaches close to advertised 28 mph top speed
- Battery hidden inside the frame for a clean look
- Front and rear suspension smooth out bumps
- Customer service responds within about a day
- Loose bolts on arrival are common, check the crank and wheel
- Some units had wheel or frame fitment problems
- Drivetrain parts (chain, chain guard, kickstand) have broken early
- Battery capacity has measured below the advertised spec for at least one buyer
Performance notes
Multiple riders confirmed the bike reaches close to its advertised 28 mph top speed, with one 270-pound rider hitting that mark. The battery sits hidden inside the frame rather than mounted externally, which several owners liked for its look. Build consistency is the weak point: reported failures range from a poorly fitting front wheel to a broken kickstand, chain, and chain guard, and one reviewer measured battery capacity below what was advertised.
