Happyrun F18 2.0
A 60V, 6,000W peak electric dirt bike on 17 and 14 inch wheels, with reverse, NFC card start and a magnetic kill switch. Happyrun claims 46 mph. On the GPS with Ben at about 200 lb it did 41 mph and stopped from 28 mph inside 20 ft.
The rear suspension is set up soft. At about 200 lb Ben went through all the travel with the spring wound all the way up, and said the bike is designed for a 12 to 16 year old, roughly 100 to 150 lb. Happyrun rates it for 300 lb and riders up to 6'1", so check your own weight against his notes before you buy. The price moves with Happyrun's sales, so the number above is the store's price on November 2, 2026.

The Gauntlet
What I Actually Measured
See every test in the video →Happyrun claims 46. Mode 1 topped out around 18 mph and mode 2 at 28 on the GPS, then mode 3 climbed to 41. With the wheel spinning and no load it read 47, so the claim is a no-weight number. A lighter rider should get closer.
My usual hill gives underpowered bikes a hard time. Ben carried about 30 mph before the hill and held 30 mph uphill. Plenty of power for a bike this size, and he noted it would climb faster and top out higher for a lighter rider.
Mode 1 cuts the power at about 19 mph, which makes it the one for areas with a speed limit. Mode 2 pulled to 26. Mode 3 read 23, 27, then 29 mph by the pullout.
It stopped with room for another half a bike. Ben called it respectable rather than the best he has seen, and said the brakes could use more time to bed in.
At 16 miles the screen still showed three bars but the bike had little power left, and a second hill climb at 15.7 miles read only 19 mph with visible voltage sag. Happyrun claims 60 miles. This is a half-battery report, not a range test to empty.
The bike wants to go, but a slow crawl is manageable. Past about a quarter inch of twist it keeps pulling, so Ben would want to tweak it. Fine for a first bike, in his words.
Plan Your Ride
Your Range, Not Mine
My 16 miles at about half battery came from a mix of hills, top speed runs, a few minutes of beach and trail, and a 200 lb rider. Set your own speed, terrain and weight below to plan a ride inside a window. Happyrun's 125 lb bike weight is a claim, and the 60 mile range is Happyrun's too.

What's On The Bike
Mid-Drive Power
60V 27Ah · 6,000W peak · 245 Nm (Happyrun claims)
A Chain, A Sprocket And Three Modes
A big gear on the motor drives a chain to the rear sprocket. Ben called the gearing a happy medium between top speed and torque. Mode 1 caps at about 18 mph, mode 2 at 28, and mode 3 goes over 40.
Reverse Is New On The 2.0
Press R, twist, and the bike backs up at 2.2 mph by the handbook. Ben used it to get out of a wet spot on the off-road section, and the loose stuff did not stop it.
Open Frame, Swappable Battery
The battery and motor sit in the middle of an open frame, sealed but exposed so they stay cool and easy to work on. A couple of screws and the pack comes out, so a spare battery is an easy swap.
Soft Suspension
Hydraulic fork · coil-over rear shock with spring preload
Springy At 200 Lb
Ben compared it to an old worn-out mattress where you feel the springs. With the preload all the way up he could still bottom it out, and he called the rear shock the first thing he would change.
Set Up For Lighter Riders
Ben's recommendation is a 12 to 16 year old, roughly 100 to 150 lb. For riding on the street, grass, gravel and back roads it is fine. For jumps or the track he says to upgrade the suspension.
Weight Balance
The battery sits in the middle of the frame, and Ben said that helps the overall balance. The seat pushes you toward the middle and front, which keeps weight on the front wheel.
Brakes And Tires
Hydraulic discs · 70/100-17 and 90/100-14 knobbies
Big, Meaty Brakes
Hydraulic discs that stopped Ben from 28 mph inside 20 ft. He wondered if the front rotor was smaller than on other bikes he has ridden. Happyrun lists 190 mm discs.
Soft, Grippy Tires
Sharp dirt knobbies on a 17 inch front and 14 inch rear. Ben felt "velcroed" to the pavement and had plenty of grip off-road. The softer rubber will wear out faster.
Rear Lights And Turn Signals
Headlight, tail and brake light, rear turn signals, a horn and a plate holder. Front turn signals are the one thing it is missing, and there are no mirrors.
The Cockpit
Card Start, Kill Switch, Reverse
Colour display, three levels, a magnetic lanyard
Hold the power button to wake the display, then tap the NFC card on the NFC icon to unlock the bike. The magnetic lanyard has to be on its slot or there is no power, and pulling it cuts the motor. The plus and minus buttons switch between levels 1, 2 and 3.
The screen is basic. Ben said it shows speed and battery bars with no range figure and no battery percentage, so it was hard to tell how much was left. Press R for reverse, and the P2 setting switches miles per hour and kilometres per hour.
The grips are hard plastic, which Ben would swap. The full-twist throttle is new on the 2.0, and the original F18 had a half twist.
Find Your Fit
Size & Fittings
F18 2.0 17″ / 14″ · Youth To Light Adult
Will It Fit You?
- Seat height26.5"
- Wheelbase45.4"
- Weight125 lb (claimed)
- Max load300 lb (rated)
- Rider height3'11" – 6'1"
- Ben's pick100 – 150 lb
It is a small, low bike with big wheels, the kind of pit bike shape Ben likes. The seat is thin, so smaller riders will appreciate how little is between their legs, and it sits you toward the middle where the padding is. Ben is close to 200 lb and sank through the foam to the hard spots. Happyrun lists 300 lb as the maximum load, but his advice is 100 to 150 lb for the ride quality, and a stiffer rear shock if you are heavier.

The Bike Cave Verdict
Ben's Take
“If you are on a sub $1,500 budget and you want to get yourself a 60 volt e-moto to go rip around the woods, I would come and look at this thing. If you are well under 200 pounds, this is a lot of bike.”
“The suspension for me is probably this bike's lowest point. I don't feel like this bike was meant for a 200 pound rider.”
“If you're 150 pounds and even below and you want something super powerful and super cheap, come and check this thing out.”
👍 What I loved
- 41 mph on the GPS from a 60V bike at this price
- Stops from 28 mph inside 20 ft
- Reverse, NFC card start and a magnetic kill switch
- Rear turn signals, brake light, horn and plate holder
- Grippy soft tires that dig into loose stuff
- Open frame and a battery you can swap with a couple of screws
- Mode 1 caps the speed for new riders
- Thin seat suits smaller riders
👎 What to know
- Rear suspension is soft and bottoms out at 200 lb
- Power faded by half battery, and 16 miles is short of the 60 mile claim
- Throttle gets touchy past a quarter twist
- Hard plastic grips and a basic screen with no range readout
- No front turn signals or mirrors
- Ben would pick a bike rated for more weight if he wanted jumps or the track
The Million-Dollar Question
Who Is The F18 2.0 For?
You want a first electric dirt bike for a teen or a rider around 150 lb or less, with a speed-limiting mode 1 and a kill switch.
You are on a sub $1,500 budget and want 60V and 6,000W peak for the woods, back roads and gravel, with reverse for when you get stuck.
You are close to 200 lb or more and want jumps or the track. Ben would look at a bike with a stiffer shock rated for more weight, or budget for a rear shock upgrade.
Frequently asked questions
How fast is the Happyrun F18 2.0?
41 mph on the GPS in mode 3 with a rider close to 200 lb. Mode 1 read about 18 mph and mode 2 about 28 mph. Happyrun claims 46 mph. With the wheel spinning and no load Ben saw 47, so the claim holds with no weight on the bike. A lighter rider should get closer to it.
How much is the Happyrun F18 2.0, and is there a discount code?
From $999 for the Red and $1,099 for the Black, against a struck list price of $2,599 (Happyrun US store, read November 2, 2026, during Happyrun's Black Friday sale). Bundles with a helmet add $100. Use code TBC100 for $100 off. Ben filmed it when the Black was $1,259, so check the store for today's number.
How far does it go on a charge?
Ben rode about 16 miles and the screen showed roughly half the battery, with power fading by then. He did not run it to empty, so that is a half-battery report and not a full range figure. Happyrun claims up to 60 miles on the 60V 27Ah battery.
Does the Happyrun F18 2.0 have reverse?
Yes, it is new on the 2.0. Press R once, twist the throttle and it backs up, then press R again to leave reverse. The handbook lists 2.2 mph. Ben used it to get out of a wet trail edge on the off-road section.
Is the F18 2.0 good for adults?
It depends on weight. Happyrun rates it for riders 3'11" to 6'1" and 300 lb. At about 200 lb Ben found the suspension too soft even with the rear spring wound all the way up, and said the bike is set up for a 12 to 16 year old, roughly 100 to 150 lb. Under that weight it is a lot of bike. Over it, plan on a rear shock upgrade.
What is new on the F18 2.0 compared with the original F18?
Happyrun's own comparison lists four changes: a magnetic emergency kill switch, reverse, a colour display with NFC card unlock, and a full-twist throttle instead of a half twist. The original came in red only, and the 2.0 comes in red or black. Motor, 46 mph claim and 300 lb load rating carry over, and the old F18 battery does not fit the 2.0.
Is the Happyrun F18 2.0 street legal?
Ben rode it off-road and on back roads, and told viewers to respect their local laws. It has a headlight, tail and brake light, rear turn signals, a horn and a plate holder, but no front turn signals and no mirrors. Check what your state requires before you ride it on public roads.
