Quick Answer: The Ariel Rider Kepler (around $1,699) is the best Ariel Rider electric bike for most riders — a 750W motor (1,940W peak, 118 Nm torque), a 1,040Wh Samsung battery good for up to 75 miles claimed, and UL 2849/2271 certification. Want more battery and an off-road-tuned mode? The X-Class 60V ($1,799 off-road edition) adds a dual-battery Performance trim with up to 105 miles claimed range. Chasing serious off-road-only speed? The Grizzly 72V ($3,199) runs an 8,000W-peak motor to a claimed 60+ mph — but it’s explicitly not street-legal.
Ariel Rider is a US-based e-bike brand that has leaned into big-battery, high-power builds since 2014, competing with Ride1Up and Onyx in the moped-style and off-road-power segment. We ranked the current lineup on hardware, and we’re upfront about a real split between the brand’s business accreditation and its customer-service track record.
Ariel Rider in 2026, by the numbers
- 1.6 out of 5 on Trustpilot, with 92% of reviews at 1 star — out of just 26 total reviews. That’s a small sample, but a consistently negative one, with recurring complaints about slow warranty response and shipping damage.
- BBB A+ rating, accredited since January 2024 — a business-registration and complaint-handling score, not a customer-satisfaction score; the BBB’s own profile notes customer reviews aren’t factored into the letter grade.
- 8,000W peak power (3,000W rated) on the Grizzly 72V, roughly four times the peak output of the Kepler — the highest-power model in Ariel Rider’s current lineup, and explicitly not street-legal.
- 1,040Wh battery on the Kepler, among the larger single-battery packs at this price point, rated for up to 75 miles claimed on Class 2 pedal-assist.
- 400 lb payload on both the Kepler and Grizzly 72V, with the X-Class 60V rated slightly lower at 350 lb.

The Kepler’s 1,040Wh battery and UL-certified electrical system make it the safest bet in Ariel Rider’s lineup for daily commuting, without the off-road-only limitations of the Grizzly. For how it stacks up against other UL-certified fat-tire commuters, see our best fat tire electric bike guide.
2. Ariel Rider X-Class 60V — Best Dual-Battery/Off-Road Value
Ariel Rider X-Class 60V
- 750W rear hub motor in two trims: Off-Road (110 Nm, single 60V 20Ah/1,200Wh battery, 45-65 miles claimed) and Performance (132 Nm, dual 60V 35Ah/2,100Wh batteries, 85-105 miles claimed).
- Full front-and-rear suspension with 80mm+ travel, 20" x 4.5" front / 20" x 5" rear fat tires, 203mm 4-piston hydraulic brakes, and an IP65 water-resistance rating.
- 350 lb payload capacity; bike weight runs 108 lb (Off-Road, single battery) to 130 lb (Performance, dual battery) — sized for riders 5'0" to 6'4".
The X-Class 60V is the pick if you want more range headroom than the Kepler without stepping up to the Grizzly’s off-road-only classification — the Performance trim’s dual 2,100Wh battery setup is among the largest we’ve seen on a still-street-legal e-bike. Compare it to other dual-battery, long-range builds in our best long-range electric bike guide.
3. Ariel Rider Grizzly 72V — Best Off-Road-Only Performance
Ariel Rider Grizzly 72V
- 8,000W peak motor (3,000W rated, oil-cooled) with 250 Nm of torque and a 72V 45Ah (3,240Wh) dual-pack battery — Ariel Rider rates it for 60+ mph off-road.
- Full suspension (100mm front travel with lockout, 80mm rear on a 210lb-spring shock), 20" x 4.5" fat tires on 36-spoke rims, and 6-piston hydraulic brakes on 220mm rotors front and rear.
- 400 lb payload at 180 lb bike weight. Sold explicitly as a Private Property Bike (PPB) — Ariel Rider's listing states it is not street-legal and is intended for private property and closed courses only, a real change from earlier Grizzly generations that shipped as a slower, street-legal moped-style build.
The current Grizzly 72V is a different animal from the moped-style Grizzly we’ve referenced elsewhere on this site — it’s now an explicitly off-road-only PPB with roughly four times the peak power. If you need something you can legally ride on the street, look at the Kepler or X-Class 60V above instead, or see how it compares to other high-speed, off-road builds in our fastest electric bike ranking.
How to choose an Ariel Rider electric bike
- Check street-legal status before you buy. The Kepler and X-Class 60V both ship Class 2/3 street-legal; the Grizzly 72V and pre-order MUDD 72V are Private Property Bikes only.
- Match battery size to your commute, not the spec sheet ceiling. The Kepler’s 1,040Wh pack covers most daily commutes; only step up to the X-Class 60V’s dual-battery Performance trim if you regularly need 80+ miles between charges.
- Weigh the BBB/Trustpilot split seriously. An A+ BBB rating reflects business registration, not service quality — Ariel Rider’s Trustpilot score points to real, recurring warranty and shipping complaints, so factor slower support into your buying decision.
- Confirm current stock and pricing before ordering. Ariel Rider runs frequent site-wide sales, and the Grizzly 72V and MUDD 72V PPB models have shipped as pre-order-only at points in 2026.
The bottom line
The Ariel Rider Kepler (about $1,699) is the best Ariel Rider electric bike for most riders — a UL-certified, 1,040Wh fat-tire commuter with a real 75-mile claimed range. The X-Class 60V ($1,799-2,399) is the move if you want a dual-battery, longer-range build that’s still street-legal, and the Grizzly 72V ($3,199) is for off-road-only riders who want serious peak power and don’t need to ride it on public roads. Just weigh Ariel Rider’s thin, mostly negative Trustpilot record against its BBB accreditation before you buy — and confirm street-legal status on whichever model you choose.
