BurchdaBikes RX80 Fat Tire E-Bike Review

If you’ve been hunting for a do-it-all fat tire e-bike that doesn’t demand a second mortgage, the BurchdaBikes RX80 review is going to get your attention fast. This is a full-suspension, 1000W peak beast built around 26×4-inch fat tires, and it retails at just $1,299 direct from BurchdaBikes. That price-to-spec ratio is genuinely hard to ignore.

The RX80 targets riders who want versatility above all else — the kind of person who commutes on weekdays, hits light trails on weekends, and occasionally needs to haul gear through gravel, sand, or snow without overthinking it. The dual suspension setup (front fork plus rear shock) gives it legitimate off-road credentials, while the 48V 20Ah battery — that’s a substantial 960Wh — promises up to 70 miles of range on a single charge. It’s Class 3 capable, hitting up to 28mph in higher assist modes, and includes a throttle for those moments when you just don’t want to pedal at all.

Component highlights include a 7-speed Shimano drivetrain, hydraulic disc brakes, integrated front and rear lights, and a color LCD display. For a sub-$1,300 bike, that’s a spec sheet that should make pricier competitors sweat.

The RX80 is built for the budget-conscious adventure commuter — someone who rides 5 to 20 miles each way to work but also wants the option to explore gravel paths and unpaved trails without swapping bikes. If you live somewhere with rough roads, seasonal weather, or mixed terrain, the fat tires and dual suspension make this a year-round machine rather than a fair-weather toy.

Fitness-wise, this suits beginner to intermediate cyclists who appreciate motor assist on longer or hillier routes but still want the option to pedal meaningfully. Heavier riders will also appreciate the fat tire stability and the robust frame. If you’re a performance-focused trail rider chasing technical singletrack, you’ll want something purpose-built. But if your definition of adventure is a varied daily ride with occasional dirt detours — all under $1,300 — the RX80 makes a compelling case for itself.

On the road, the 1000W peak brushless rear hub motor delivers smooth, confident power. Torque comes on progressively through the 5 PAS levels rather than jolting you forward — PAS 1 and 2 are genuinely usable for light commuting without burning through your battery in an hour. Hit PAS 4 or 5 and you’ll feel the motor assert itself, pulling you up modest inclines without breaking a sweat. The throttle-only mode works well for flat stretches when your legs need a break.

The 960Wh battery is the headline number here. In real-world mixed use — PAS 2-3, some throttle, varied terrain — I’d realistically expect 45 to 55 miles per charge. The claimed 70 miles is achievable but requires disciplined PAS 1 riding on flat ground. Charge time runs approximately 6-7 hours from empty with the included 4A charger.

The front suspension fork soaks up road chatter adequately, and the rear shock makes a noticeable difference on broken pavement and light dirt trails. Tektro hydraulic disc brakes provide firm, consistent stopping power — important given this bike’s 75lb weight. The Shimano 7-speed shifts cleanly, though the cassette range means steep climbs above 15% grade will test you even with motor assist.
