Can I touch the ground? If your inseam (in shoes) is at or near the lowest seat height, you can reach the ground from the seat with the saddle all the way down.
Near the top or bottom of that range? That's where fit matters most, so check with us before you order.
Still not sure? Call the Ride Desk at (855) 970-3574 with your height and inseam and we'll tell you straight.

Ride Until You're Done. Not Until the Battery Is.
Every gas dirt bike owner knows the routine.
Mix the fuel. Prime it. Pull the cord. Pull it again. Wave an apology at the neighbors. Then, two hours later, clean the carb because it sat too long.
The HappyRun G18 Pro skips all of it. Twist the throttle and it pulls, quietly, on a big removable battery rated for up to 75 miles. That's a full Saturday on the back forty, not one lap and a recharge.
One thing first: the G18 Pro is an off-road electric dirt bike, not street legal, for private land and permitted trails. Here's what's inside.
Five Speed Modes: Why That's a Big Deal
The G18 Pro has five speed modes: 10, 16, 22, 28, and 38 MPH. That makes it unusually easy to grow into. Crawl through a technical section at 10, cruise the fields at 22, open it up on the fire road at 38. It's a forgiving bike for riders who are newer to dirt, and still fun for experienced ones.
Power and Torque
The 60V motor peaks at 4,500 watts (the burst you get when you open the throttle) with 200 Nm of peak torque. Torque is the twisting force that pulls you up climbs and out of ruts, and electric motors deliver it instantly. A half-twist throttle controls it, and an NFC card unlocks the bike.
The Battery: Where the Range Comes From
The 60V 35Ah battery holds about 2,100 watt-hours (think of it as the gas tank), and it's removable, at about 19 pounds, so you can charge it in the garage, the truck, or the cabin. HappyRun rates it at up to 75 miles. The low modes stretch toward that figure; full-throttle trail riding lands well below it. A full charge takes about 6 to 8 hours.
Suspension, Wheels, and Brakes
- Full suspension: a hydraulic front fork and a rear spring shock take the rocks, roots, and ruts.
- 19" front and 17" rear off-road wheels, true dirt-bike sizes. The big front wheel rolls over obstacles that stop smaller wheels.
- Hydraulic disc brakes with a 180mm front and 203mm rear rotor bring the bike down under control.
- IPX5 water resistance, so rain doesn't end the ride.
- A headlight with integrated brake light and turn signals, plus an LCD display.
The Honest Part
- "Is it street legal?" No. It's an off-road electric dirt bike for private land and trails that allow them. Check your local rules.
- "Will I really get 75 miles?" In the lower modes, it can stretch toward that. Full-throttle riding lands well below it.
- "How much assembly?" It arrives about 80% assembled, so plan on roughly an hour with basic tools. It weighs 119 pounds, so have a helper for unboxing.
Is This Your Ride?
The G18 Pro fits riders about 5'3" to 6'5", with a 33" seat height, and carries up to 350 pounds. Pick it for long range, easy-to-control power, and the flexibility of five speed modes.
Want more top speed? The G300 Pro steps up to a 72V system and 50 MPH.

G18 Pro Questions
Is it street legal?
No. The G18 Pro is an off-road electric dirt bike for private land and permitted trails. Rules vary by state and county, so check yours, and message us if you want help.
Is it good for a newer rider?
It's one of the more forgiving options, thanks to the 10 and 16 MPH modes. Start low, wear full protective gear, and step up as you get comfortable.

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.
Is it street legal?
No. The G18 Pro is an off-road electric dirt bike for private land and permitted trails. Rules vary by state and county, so check yours, and message us if you want help.
Is it good for a newer rider?
It's one of the more forgiving options, thanks to the 10 and 16 MPH modes. Start low, wear full protective gear, and step up as you get comfortable.
Why buy from Vortex instead of somewhere else?
It's the same factory-sealed HappyRun bike with the full manufacturer warranty. What you get on top: the free gear kit shown above, 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 HappyRun 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. Payment options through Shop Pay Installments are subject to an eligibility check and are provided by these lending partners: affirm.com/lenders.
