EUNORAU R1 Compact 4000W Electric Dirt Bike – 72V, Mid-Drive, Full Suspension Off-Road
55 MPH of Silence, in a Nimbler Package
Full-size dirt bikes have one drawback for a lot of riders.
They're tall. A high seat means tiptoeing at every stop, and a tall bike feels like more to wrestle in tight woods and switchbacks. If you're of average height, or you ride technical trails more than open fields, a smaller bike is often the faster, more fun choice.
The EUNORAU R1 Compact takes the R1's 72-volt system and big battery and puts them on smaller wheels with a lower seat. It's quieter than any gas bike, it needs no gas or oil, and it's easier to handle where the trail gets tight.
To be clear: this is an off-road electric dirt bike, not an e-bike. It has no pedals. Here's what's inside.
Smaller Wheels, Lower Seat: Why It Matters
The R1 Compact rolls on a 17" front and 16" rear wheel (tires 80/100-17 and 80/100-16) instead of the full-size R1's 19s. That drops the seat to about 30.7 inches (780mm), so more riders can get a foot down, and it makes the bike quicker to turn and easier to pick through tight trails. The trade-off: smaller wheels don't roll over big obstacles quite as easily as 19-inch wheels.
Power, Explained
The 72V mid-motor is rated at 4,000 watts (what it delivers continuously) and peaks at 8,000 (the burst when you open the throttle). It makes 330 Nm of peak torque, the twisting force that pulls you up hills and out of ruts, delivered instantly, with no engine to rev. The strongest hunting e-bikes we carry make 160 Nm, for comparison.
Top speed is 55 MPH. Two modes, Eco and Sport, let you choose between all-day cruising and full power, and Sport mode adds regenerative braking, which uses the motor to help slow you on descents and returns energy to the battery.
Battery, Suspension, and Brakes
- A removable 72V 35Ah LG-cell battery, roughly 2,500 watt-hours, rated for up to 75 miles at under 16 MPH. The included 72V 10A fast charger refills it in about 4 hours.
- A FASTACE fork with 203mm of travel (about 8 inches) and an 85mm rear shock.
- Four-piston hydraulic brakes with 203mm rotors front and rear, with motor cutoff on the levers.
- IP65 water resistance: sealed against dust and protected from water spray.
- LED headlight, brake light, electronic horn, and a USB-C port.
It weighs 130 pounds.
The Honest Part: Where You Can Ride It
- "Is it street legal?" No. It's a high-powered electric dirt bike without pedals, for private land, OHV areas, tracks, and trails that allow motorized vehicles. It isn't an e-bike and isn't allowed on bike paths. Check your local rules before riding anywhere public.
- "Is it a kids' bike?" No. Despite the smaller wheels, it's a 55 MPH, 8,000-watt machine. Ride with full protective gear, and follow your state's age rules for off-road vehicles.
- "Will I get 75 miles?" Only riding efficiently under 16 MPH. Sport-mode riding brings it down substantially.
Which R1 Is Right for You?
Pick the R1 Compact if you're of average height, prefer a lower seat, or ride tight, technical trails. For bigger wheels that roll over rough ground more easily, choose the full-size R1. For maximum power, the R1+ steps up to 5,000W and 500 Nm. The Compact comes in Black, Camo, and Silver.

Quick answers
The questions riders ask us most, answered up front. Want to talk it through? The Ride Desk is glad to help by chat or at (855) 970-3574.
How tall do I need to be?
The seat sits about 30.7" off the ground, lower than the full-size R1. Send the Ride Desk your height and inseam and we'll tell you which R1 fits best.
How much assembly is required?
It arrives mostly assembled. Finishing setup takes under an hour with basic tools, and we're a message away if you get stuck.
Why buy from Vortex instead of somewhere else?
It's the same factory-sealed EUNORAU bike with the full manufacturer warranty. What you get on top: our price match (find it lower at another authorized dealer and we'll match it), and the Ride Desk. If anything goes wrong, you send us a message and a short video and we handle the warranty claim with EUNORAU for you, so you're never stuck in a support queue alone.
When will it arrive?
Usually in 7–10 days. Shipping is free to the lower 48 by FedEx or UPS, and a signature is required so your bike is never left on the porch. You'll get tracking by email as soon as it ships.
How much assembly is there?
The bike arrives mostly assembled. You'll typically attach the handlebar, front wheel, pedals, and seat, and the manufacturer's step-by-step video walks you through it. Get stuck? Send the Ride Desk a photo and we'll talk you through it.
Will it fit me, and can I handle it?
Check the specs above and the size chart in the photos. If you're near the edge of the height range, between frame sizes, or unsure about the weight, send us your height and inseam. We'll tell you straight, even if the answer is a different bike.
How far will it really go?
The range in the specs is the manufacturer's test number, usually measured with a light rider in a low assist level on flat ground. Heavier riders, hills, wind, cold, and throttle use all shorten it. Tell us your weight and your usual route, and we'll give you a realistic estimate.
Is it legal where I ride?
The class rating and top speed are in the specs below. In most states, an e-bike ridden within its Class 1, 2, or 3 limits doesn't need a license, registration, or insurance, but trail and town rules vary, so check yours. Any higher-speed modes are for private property only.
How should I charge and store it?
Use the included charger, charge on a hard surface away from anything flammable, and unplug once it's full. For longer storage, keep the battery partly charged in a cool, dry place and top it up now and then. Your owner's manual has the exact guidance for your model.
Can I pay over time?
Yes. Choose Shop Pay Installments at checkout: buy today and pay in 4 or more payments starting at 0% APR. Checking your eligibility won't affect your credit score. Rates from 0–36% APR.
