Reachable area estimated over the road network. Real range varies with assist level, terrain, rider weight and wind.
Start with the part that changes everything else: the Patrol 52 advertises 40 mph. In the US the three e-bike classes top out at 28 mph, and the power ceiling is 750 W nominal. On those numbers this is not an electric bicycle in the eyes of the law: it's a motor vehicle. In practice that means almost nowhere can you take it into a bike lane or onto a trail, and riding it on public roads without registration and insurance is an offense.
That said, for what it actually is — a light electric dirt bike — the spec sheet is impressive. Dual hydraulic disc brakes, a 19-inch front and 17-inch rear wheel on off-road tires, a high-carbon steel frame, NFC card start and a color display. It charges in three and a half hours and takes 300 pounds.
The battery figures are a problem: the bullets advertise 52V 30Ah, or 1,560 Wh, while the Amazon spec table says 624 Wh. That's a factor of two and a half between them. We left the field blank rather than pick one by eye. Nominal power isn't published either: the 4,000 W is a peak figure, which is marketing, not law.
It's the highest-rated bike in the US lineup at 4.6, and the reviews confirm what it promises: it does hit 40 mph. They also confirm what worries us — several are from parents who bought it for teenagers.
Anything marked «—» is a figure the manufacturer doesn't publish. We don't fill those in by eye.

| Legal warning | At a claimed 40 mph, this machine fits none of the three US e-bike classes, which top out at 28 mph. Legally it is a motor vehicle, and in almost every state it cannot be ridden in a bike lane or on a trail |
|---|---|
| Battery | The bullets advertise 52V 30Ah (1,560 Wh) with 21700 cells, but the Amazon spec table says 624 Wh. Those figures are incompatible and we could not confirm which is right, so we left the field blank |
| Power | 4,000 W is a PEAK figure. The manufacturer does not publish nominal power, which is what the law counts |
| Wheels | 19-inch front and 17-inch rear with off-road tires: dirt-bike geometry, not bicycle geometry |
| Start | NFC card start and a 2.3-inch color LCD |
| Certification | The maker mentions 'triple UL certification' without saying which standards |
| Manufacturer | Shenzhen Xingtu Innovation Technology Co., Ltd |
A summary of the reviews published on Amazon.com as of 2026-08-21.
4.6 out of 5 from 53 reviews, all verified purchases and fairly enthusiastic. A 6'2", 240-pound rider says he's comfortable and hits 40 mph with no trouble; others call it fast and well built, with the odd complaint about paint scratches on arrival. Nobody reports mechanical or battery failures. That said, there's a pattern worth naming: several of the most positive reviews are from parents who bought it for teenage children ('my son loves it'). At 40 mph and outside every legal class, that's a use worth thinking twice about.
