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.
Reviewers who tested it at heavier body weights reported it held speed and stability well, matching the fat tire and dual motor spec sheet. 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
What buyers say
From Amazon customer reviews.
Reviewers who bought the V3-2 for its size and power came away satisfied, including a rider over 300lbs who found it stable at 25mph. Complaints centered on small parts failing, such as a snapped shifter lever, and in one serious case a motor breakdown four months in that left the buyer without local repair options and dealing directly with the manufacturer for two months.
Strengths and trade-offs
Drawn from this product's published specifications.
- 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.
