Strong acceleration and a comfortable assembly experience for most buyers, but a reported battery swelling incident and pedal quality complaints are worth weighing before buying.

Overview
A dual motor mountain e-bike rated for 9000W peak combined output and a 46 mph top speed, built around a 52V 34Ah battery for up to 100 miles of range. Reviewer feedback is mostly positive on power and assembly, but includes two serious complaints: a battery reported to have swelled and smoked, and pedals described as cheap and unsafe.
The 9000W peak figure comes from two 4500W motors working together, and the listed numbers show the top speed drops from 46 mph unloaded to closer to 40 mph with a 165 lb rider aboard, a useful distinction most listings skip. Given a reported battery safety incident in the review set, buyers should follow the charging and storage guidance closely and monitor the pack for swelling.
- Dual 4500W motors, 9000W peak combined output
- 52V 34Ah 1768Wh battery, 45 to 100 mile range
- Dual front suspension plus seat spring damping
- Six riding modes including single and dual motor options
Who it's for
Riders who want serious power for mixed mountain and commuter use and are comfortable assembling a heavy bike. Not a fit for anyone who wants a lightweight or low maintenance machine, or who is wary of the battery safety report from one buyer.
What buyers say
From Amazon customer reviews.
Reviewers generally praised the acceleration, easy hill climbing, and straightforward assembly with included tools and a video guide, with one buyer topping 42 mph on flat ground. Two reports stand out as genuine concerns: one buyer described the pedals as cheap and unsafe, and another reported the battery swelling and emitting smoke, a safety flag worth checking against for this specific unit.
Performance notes
The two 4500W motors deliver a combined 220 Nm of torque, and the listing states the bike can climb 45 degree inclines; a reviewer measured 42 mph with a tailwind. Running both motors together drains the 52V 34Ah battery faster than single motor mode, which one reviewer flagged as reducing effective range below the advertised 45 to 100 miles. Front dual suspension and seat springs are the main comfort features on rough terrain, backed by front and rear hydraulic disc brakes.
