Riythrust R-R3 Electric Bike Review 2026: Is 5000W Dual Motor Worth $1,390?

The Riythrust R-R3 e-bike is a dual-motor off-road machine built around two motors that together produce 5000W peak output, accelerating the bike to 45MPH and pulling riders up 45-degree inclines where single-motor bikes stall. Six riding modes — including three pedal assist levels and full throttle — let you balance performance against range, giving you direct control over how aggressively both motors engage.

The 52-volt, 32 amp-hour battery stores 1,664 watt-hours of energy, roughly three times the capacity of a standard 48V 15Ah commuter e-bike. In single-motor mode the Riythrust R-R3 electric bike covers up to 100 miles per charge; run both motors at full power and expect around 60 miles. The 26x4.0-inch fat tires grip sand, snow, loose gravel, and packed dirt trails where narrower tires lose traction, and full suspension with a lockable front fork and hydraulic rear shock absorbs trail chop on extended backcountry rides.

At $1,390, the Riythrust R-R3 sits near the lower end of the 5000W dual-motor fat tire ebike category, where comparable models typically run $1,600–$2,200. That positions the R-R3 as one of the more accessible entry points into high-power electric mountain biking without the cost-per-mile penalty of premium brands. Hydraulic disc brakes front and rear stop the bike from 45MPH in wet and muddy conditions. The frame supports riders up to 330 lbs, the rear rack handles cargo loads, and built-in LED lights, an LCD speed and battery display, USB charging port, and cruise control cover the practical day-to-day features.

The Riythrust R-R3 ebike does not fold, verified buyer reviews number fewer than 10 as of early 2026, and there is no companion smartphone app for ride logging or remote diagnostics. Riders in jurisdictions that cap electric bikes at 28MPH (Class 3) or 20MPH (Class 2) need to confirm local regulations before riding shared paths, since the R-R3's 45MPH capability exceeds both limits.
