Confidence: limited - limited rating history.Last refreshed Jun 21, 2026. Data-computed, not a hands-on test. Compiled by the ProductDome Research Team.
Overview
Retro styled e-bike with a low step frame and vintage saddle, built around dual 1500W motors (3000W peak combined) and a choice of 48V battery sizes. Reviewers who logged 100 plus miles describe genuine torque and a comfortable ride, at a price well under similarly equipped Super73 style bikes.
This is one of the rare budget ebikes that pairs two motors with two swappable batteries, full suspension, and hydraulic brakes rather than skimping on one of those to hit a price point. The vintage look (quilted saddle, low step frame) is a styling choice, not a spec, so buyers drawn to the classic motorcycle silhouette should weigh that against a more conventional mountain e-bike frame if fit matters more than looks.
- Dual 1500W motors, 3000W peak combined output
- 20x4 inch fat tires with six layer shock absorption
- Digital display tracks mileage, battery, and five ride modes
- Companion app for vehicle monitoring
Who it's for
Riders who want a stylish commuter with real off road capability and don't mind assembling a bike shipped in one large box. The wide, low step frame and rear pegs also suit riders who occasionally carry a passenger.
What buyers say
From Amazon customer reviews.
Buyers consistently called out the combination for the price: two motors, two batteries, full suspension, and hydraulic brakes together, plus included extras like a spare tube, pump, lock, and phone holder. The main complaint was seat padding that looks thicker than it feels, and one buyer received a box with an axle poking through from rough handling in transit; multiple reviewers also praised how easy the bike was to put together and how responsive customer service was.
Strengths and trade-offs
Drawn from this product's published specifications.
- Two motors and two batteries where most bikes at this price offer one
- Full suspension plus hydraulic brakes included, not optional add-ons
- Ships with spare tube, pump, lock, and extra brake pads
- Reviewer with 100 miles logged reports genuine torque and smooth ride
- Seat cushioning is thinner than it appears, with a hollow plastic base under the leather look cover
- One buyer's unit arrived with an axle poking through the shipping box
Performance notes
The claimed 37.5 mph top speed and 35 degree slope climbing come from the combined 3000W peak output of the two motors working together, with the 7 level pedal assist system letting riders dial in how much of that power they use. The six layer shock system (fat tires, front fork, rear shock) is what a reviewer credited for the smooth 100 mile test ride. Range depends on which battery pack ships: up to 40 miles on throttle alone or 60 miles with pedal assist, with an 8 to 9 hour recharge.
