Overview
Kaijielaisi's V3-2 is an all-wheel-drive fat tire electric bike built around dual motors with a combined peak output of 4000W, a 48V 22.4AH removable battery, and dual 180mm hydraulic disc brakes. It targets riders who want serious power on sand, snow, or steep grades rather than a light commuter.
The bike ships about 85 percent assembled, and Kaijielaisi's listing points buyers toward direct manufacturer support rather than a dealer network, a detail worth noting since owners confirm there is little local shop coverage for this brand.
- Peak 4000W dual motor output, 85 N.m torque
- 48V 22.4AH removable, UL 2849 certified battery
- Front suspension fork with dual 180mm hydraulic disc brakes
- 21-speed drivetrain with 6 selectable ride modes
Pros and cons
- Handles heavier riders (330lbs plus) without losing stability
- Strong torque for steep climbs and loose terrain
- Dual hydraulic disc brakes for wet-weather stopping power
- Fast, responsive support by one buyer's account
- No local dealer network for repairs
- Shifter lever reported to snap off
- Pedal assist can override manual pedaling and switch modes unexpectedly
- One buyer's motor issue after 4 months required self-repair with a mailed part
Performance notes
The dual motor setup and 85 N.m torque are aimed at climbing (rated for 40 degree grades) and sand or snow traction rather than top-end speed, though one rider reported the bike reaching 25mph fully loaded. The 1076WH battery is rated for 50+ miles in pedal-assist mode and 30+ in throttle-only mode, with an 8 to 10 hour charge time.
