The torque and suspension impressed reviewers enough that one called it the nicest ebike they've owned, but temper the advertised top speed against real reports of it running well under 30mph.

Overview
A fat-tire electric bike sold across 1500W/2000W/2500W peak motor tiers with matching 52V/48V battery options, rated for up to 90 miles range depending on configuration. Full suspension, dual disc brakes and a 7-speed Shimano drivetrain round out the build for adult and teen riders.
Gematio markets this as several bikes in one, spanning commuter to dirt-bike use, but reviewer experience is a useful corrective on the marketing: real top speed came in well under the claimed 30mph for at least one rider, and the bike itself is heavy at around 90 lbs. That weight and multi-mode setup suit it more to a rider who wants one do-everything bike than someone chasing race-bike speed.
- Motor tiers up to 2500W peak across three configurations
- Battery options up to 52V 25Ah for 90-mile range
- Full suspension with dual disc brakes
- 7-speed Shimano drivetrain, UL2271 and UL2849 certified
Who it's for
Families or riders wanting one heavy-duty ebike that covers commuting, trail riding and casual cruising, including teens under a parent-set speed limit. Not the choice for someone prioritizing light weight or a bike that hits its full advertised top speed out of the box.
What buyers say
From Amazon customer reviews.
Riders who tried this in pedal-assist mode praised the torque and said the rear shock suited their weight well, though the front fork got a more lukewarm adequate rating. More than one reviewer flagged that real top speed falls well short of the claimed 30mph and that the bike itself is heavy, around 90 lbs, even though it still pedals easily. One reviewer's unit had non-working front brakes, and another noted squeaky brakes and suspension along with a weak headlight. Parents buying for teens reported smooth gear transitions and an easy assembly.
