Overview
This is a fat tire electric bike sold in 1000W, 1500W, and 3000W power tiers with a 48V battery, front and rear suspension, dual disc brakes, 3 riding modes, and 7-speed gearing for street and off-road riding.
Multiple reviewers measured real-world top speed around 32 to 34mph rather than the advertised 37mph, so treat the top-end figure as optimistic. The bike ships about 90 percent pre-assembled with a video guide, and most riders got it running without major issues.
- 1000W to 3000W motor tiers
- 48V battery, up to 35Ah
- 20 x 4 inch puncture-resistant tires
- Front and rear suspension with dual disc brakes
Who it's for
Suits riders wanting a fat-tire ebike with suspension and disc brakes for mixed city and off-road terrain. Not the right choice if hitting the full advertised top speed is a hard requirement.
What buyers say
From Amazon customer reviews.
Several riders praised the power, build quality, and off-road capability, with one comparing the frame styling to a classic dirt bike. Two separate reviewers measured top speed around 32 to 34mph instead of the advertised 37mph. One unit failed to power on out of the box, and another arrived missing a front tire screw.
Strengths and trade-offs
Drawn from this product's published specifications.
- Handles hills and off-road terrain well
- Arrives about 90 percent pre-assembled
- Front and rear suspension with disc brakes
- Real-world top speed runs a few mph short of the claim
- One unit arrived dead on arrival
- One buyer's bike was missing a front wheel screw
Performance notes
The brushless motor works with front and rear suspension and dual mechanical disc brakes to handle bumpy roads, sand, and trails, while the LCD display shows speed, battery, PAS level, and mileage in real time. The 7-speed gearing across 3 riding modes lets riders shift for flat stretches or steeper climbs.
