Two Batteries. One Less Car.
Think about the trips that keep your car busy.
School drop-off. The grocery run. A passenger who needs a ride across town. The weekend loop to the park. Most of them are short, and most of them happen in the car only because a regular bike can't carry enough or go far enough.
The HappyRun G70 is a long-tail cargo e-bike built to change that. It has two batteries for real range, a motor with serious pulling power, and suspension at both ends so your cargo, human or otherwise, rides smooth. Here's what makes it work.
Torque for a Loaded Bike
The motor is rated at 750 watts and peaks at 2,000, with HappyRun listing 110 Nm of torque. Torque is the pulling force that gets a heavy bike moving from a stop and up a hill. A typical commuter e-bike makes 55 to 65 Nm, so the G70 has close to double the pull, which is exactly what you need with a passenger or a full load on the back.
Use 5 levels of pedal assist through a 7-speed drivetrain, or the half-twist throttle to move without pedaling. Top speed is 20 MPH.
Two Batteries, Explained
The G70 carries two 48V 13Ah batteries, about 1,248 watt-hours combined. Watt-hours are the size of the gas tank, and this tank is roughly double what a typical single-battery commuter carries. HappyRun rates it at up to 85 miles. That's a best-case test number; load, hills, speed, and assist level all shorten it. But for school runs and errands, it means charging far less often.
Suspension on a Cargo Bike: Why It Matters
Most cargo bikes at this price are rigid, so every bump goes straight into your load and whoever's riding on the back. The G70 has full suspension, front and rear, plus 20" × 4" fat tires (about twice as wide as a normal bike tire). Small wheels keep the load low and stable; wide tires and suspension keep it comfortable and controlled.
Safety Details
- UL 2849 certified: the safety standard for the full e-bike electrical system, which matters most when the bike charges in your garage every night.
- Hydraulic disc brakes front and rear, with motor cutoff on the levers.
- Front and rear turn signals, a 160-lumen headlight, and a brake-indicator taillight.
- NFC unlocking: tap a card to start it, no key to lose. Two NFC cards are included.
- IP54 water resistance, protected against splashes and rain.
The Honest Part
- "How much can it carry?" Up to 330 pounds total, and that includes you. A 200-pound rider has 130 pounds left for a passenger and cargo, so check your numbers before planning to carry two adults.
- "How heavy is it?" About 98 pounds. It rides stable, but it's a garage bike, not one you carry upstairs.
- "Does it come with the rear rack?" This listing is the version without HappyRun's add-on rear rack. HappyRun's rear rack and cargo accessories are available separately.
- "Will I get 85 miles?" Only in ideal conditions. Carrying a passenger or heavy cargo cuts range substantially.
Is This Your Bike?
The G70 fits riders about 5'1" to 6'5" and comes in Black and Green. Pick it if you want a cargo bike that can genuinely replace short car trips, with the range of two batteries and the comfort of full suspension.

It arrives about 90% 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 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.
