Hiboy EX6
Step-thru fat-tire commuter, UL 2849 · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 73
At $899.77 the Hiboy EX6 is a conservative fat-tire step-thru commuter from a well-known scooter brand with US service, built around a UL 2849-certified 696 Wh battery and a 500 W motor. Satisfaction leads at 86 and Quality holds at 68, but Value drags at 78 because rivals at the same price add full suspension or more battery, and Reliability sits at 78 because the EX6 is newer and has only 95 reviews. The one-year limited warranty keeps Warranty at 55, and it lands at 73, under the buy line. It is for a cautious buyer who values a certified battery and a known service network over headline specs.

Should you buy the Hiboy EX6?
The Hiboy EX6 is a conservative fat-tire step-thru commuter: 500 W motor, 25 mph, a UL 2849 certified 696 Wh removable battery, Shimano 7-speed and US-based service, for $899.77. It suits a rider between 5 ft 5 in and 6 ft 1 in who wants a certified battery and a known service network more than raw spec. At the same money, the Aipas M1 Pro has more battery and full suspension, which is why the EX6 scores below our line.
Where it earns its score
- Satisfaction at 86. Owners are happy with it, and the adjustable bars and seat fit a wide height range.
- Certified battery, solid range. UL 2849, 696 Wh, with 40 miles on throttle and 75 miles on assist claimed.
- US service. Hiboy is an established scooter brand with stateside support.
- Climbs. Rated for 20 percent grades with the 500 W motor.
What to know first
- Buy With Caution. A ViperScore of 73 is under our 75 line; Value at 78 is the issue, since $900 buys full suspension or a bigger battery elsewhere.
- Warranty is the lowest factor at 55. One year, limited.
- Front suspension only. No rear shock at a price where the Aipas M1 Pro has one.
- Reliability at 78. Middle of the pack for this category.
Our verdict
The Hiboy EX6 scores 73, Buy With Caution. It is a safe, certified, well-supported bike that is simply outspecced at $899.77. Buy the Aipas M1 Pro (77) for the same money if you want more range and full suspension, or the Heybike Ranger 2.0 (77) for $150 less if folding matters.
