HappyRun G300 Pro electric dirt bike on a trail

The HappyRun G70, G100 Pro and G300 Pro are not three trims of one bike. They are three different jobs. The G70 (around $1,379) is a long-tail cargo e-bike that tops out at 20 mph and goes up to 85 miles on its dual battery. The G100 Pro (around $2,099) is a cafe racer styled street bike rated to 50 mph with up to 78 miles of range. The G300 Pro (from $1,799) is an off-road only dirt bike that also reaches 50 mph, but only on trails and closed courses, never on the street. Pick the one that matches where you will actually ride, not the one with the biggest number.

Choose the G70 if you carry things or people

The G70 is the workhorse. The extended rear frame takes a passenger seat or a rack (the rack itself is rated to 50 lbs, the whole bike to 330 lbs), and the two 13Ah packs give it the longest range of the three at up to 85 miles. The 750W motor is modest on paper, but 110 Nm of torque is the highest in HappyRun's cargo line, and it shows when you pull away from a stop sign with a loaded rear end.

The honest limit is speed. 20 mph is the ceiling, which is exactly what makes the range and payload possible on a 98 lb bike. It is also full suspension on 20x4 inch fat tires with a 7-speed drivetrain, so it still rides like a bicycle when the load is light. It carries UL 2849 certification, worth having if it charges in a garage attached to the house.

Choose the G100 Pro if you want the motorcycle feel on pavement

The G100 Pro is the one that looks and rides closest to a small motorcycle. Gas-tank styling, a long bench seat and high bars put you upright and relaxed, and the 72V dual battery (33Ah, about 2376Wh) feeds a 3000W continuous motor that HappyRun rates to 50 mph and up to 78 miles. It comes with a 160-lumen headlight and sequential turn signals front and rear, hydraulic discs (180mm front, 203mm rear) with power cut-off levers, and IP54 sealed electronics.

At 159 lbs it is the heaviest of the three, and at 400 lbs it has the highest payload rating. Charging the dual pack takes 7 to 8 hours on the included 2A charger, so it is an overnight bike, not a top-up-at-lunch bike. And 50 mph is well above any federal e-bike class, so read the street legality question below before you plan a commute on it.

Choose the G300 Pro if you are riding dirt, full stop

The G300 Pro is not street legal and cannot be registered for road use with any state DMV. That is the trade. In return you get real motocross geometry: a 31 inch seat height, knobbed 19 inch front and 17 inch rear wheels, hydraulic discs (180mm front, 203mm rear) and an adjustable fork with 80 to 120mm of travel. The 3000W motor peaks at 6500W on a 72V 30Ah pack, and five riding modes let you hold power back for a newer rider or tight singletrack, then open it up when the trail does. Trail mode caps it at 28 mph; unrestricted off-road it reaches 50 mph.

It weighs 136.8 lbs, light enough to lift out of a rut, and is rated for riders up to 350 lbs. HappyRun says riders under 18 need adult supervision. The 31 inch seat suits taller teens and adults; shorter riders should look at the smaller G300 SE in the same series. Charging takes 5 to 6 hours with the 5A charger.

Which HappyRun is right for you?

If the bike replaces car trips with kids or groceries on board, the G70 wins on range and load and you will not miss the speed. If you want a street bike with presence and you have checked what your state allows at 50 mph, the G100 Pro is the only one of the three built for that. If you have land, trails or a track and want a proper dirt bike without a two-stroke's noise and fuel, the G300 Pro is the one, and the price difference against the G100 Pro is small enough that the decision should be about terrain, not money.

Frequently Asked Questions

Which HappyRun model is fastest, the G70, G100 Pro or G300 Pro?
The G100 Pro and G300 Pro are both rated up to 50 mph. The difference is where you can use it: the G100 Pro's 50 mph is on pavement, while the G300 Pro only reaches 50 mph off-road and is limited to 28 mph in trail mode. The G70 tops out at 20 mph because it is built for cargo capacity, not speed.

Can the HappyRun G70 handle light off-road use?
It has full suspension and 20x4 inch fat tires, so gravel paths and packed dirt are fine. It is geared for pavement and predictable routes though. For real dirt and trail riding, the G300 Pro's motocross geometry and knobbed tires are the better fit.

Do all three HappyRun models use dual batteries?
No. The G70 (48V, 13Ah + 13Ah) and G100 Pro (72V, 18Ah + 15Ah) use dual-battery setups for range. The G300 Pro runs a single 72V 30Ah pack, which at about 2160Wh is still close to the G100 Pro's total capacity.

Is the HappyRun G100 Pro street legal?
HappyRun fits it with a headlight and turn signals, but at 50 mph it is faster than any of the three federal e-bike classes (Class 3 tops out at 28 mph with pedal assist), so many states will not treat it as a bicycle. Check your state and local rules before riding it on public roads. The G300 Pro is off-road only and cannot be registered anywhere.

How much do the HappyRun G70, G100 Pro and G300 Pro cost?
As of this update, the G70 is around $1,379, the G100 Pro around $2,099, and the G300 Pro from $1,799 to $2,059 depending on color. Confirm the current price on each product page before ordering.
