HappyRun Tank G60 Pro 48V/25Ah 1000W Fat Tire Electric Bike

Frequently Asked Questions

What's the difference between the G60 and G60 Pro?

The G60 Pro features several major upgrades: a more powerful 1000W motor (vs 750W) with 2000W peak power, a larger 48V 25Ah battery (vs 20Ah) for 80+ mile range, puncture-resistant fat tires, NFC smart unlock system, and higher top speed of 36+ mph. The G60 Pro is designed for riders who want maximum performance and range.

How tall do I need to be to ride this bike?

The HappyRun Tank G60 Pro is designed for riders between 5'3" and 6'5" tall. The seat height is 34 inches, and the moped-style frame offers a comfortable, upright riding position for a wide range of body types.

Do I need to pedal at all?

No, pedaling is optional. The G60 Pro offers three riding modes: Pure Electric Mode (throttle only—no pedaling required), Pedal Assist Mode (motor amplifies your pedaling), and Manual Mode (ride like a traditional bike). You can switch between modes based on your preference.

How long does the battery last?

The 48V/25Ah battery provides 80+ miles of range per charge under optimal conditions. Real-world range varies from 35-80+ miles depending on terrain, rider weight, assist level, and riding style. The battery typically lasts 800-1,000 charge cycles (3-5 years of regular use).

How long does it take to charge?

The included 2A smart charger takes approximately 7-8 hours to fully charge the battery from empty. The removable battery design allows you to charge it anywhere—at home, in your office, or in your apartment.

Can I ride it in the rain?

Yes, the G60 Pro has an IP54 waterproof rating, meaning it's protected against water splashes from any direction. You can ride in rain and wet conditions, but avoid deep water, submersion, or pressure washing the electrical components.

How fast can it go?

The HappyRun Tank G60 Pro can reach speeds up to 36+ mph with pedal assist and throttle. Actual top speed depends on rider weight, terrain, battery level, and wind conditions.

Is it street legal?

E-bike laws vary by state and locality. The G60 Pro's high speed (36+ mph) may classify it as a Class 3 e-bike or moped in some jurisdictions, potentially requiring registration, licensing, or insurance. In many areas, you may need to limit speed to 28 mph for bike path access. Always check your local regulations before riding.

How much assembly is required?

The G60 Pro arrives 85% pre-assembled. You'll need to attach the handlebars and install the front wheel. Assembly takes approximately 45 minutes with the included tools. Tires arrive partially inflated and should be brought to proper pressure using the included bike pump.

What's the weight limit?

The maximum load capacity is 330 lbs, including the rider and any cargo. The rear rack can carry an additional 33 lbs of cargo.

What is the warranty?

The HappyRun Tank G60 Pro comes with a 1-year limited warranty covering manufacturing defects. For warranty service or questions, contact the manufacturer at service@happyrunsports.com. Eco Bikes USA provides full customer support for all purchases.

How do I switch between kilometers and miles?

Once the bike is unlocked, hold the brake lever and press the "S" button twice to toggle between kilometers and miles on the LCD display.

What are the hidden functions of the speed button?

The "S" button has multiple functions:

• Press and hold 1 second (power off) = Turn on
• Press and hold 2 seconds (power on) = Turn off
• Press once = Switch speed gears (1-5)
• Hold brake + press twice = Switch km/miles
• Press three times = Toggle trip/total mileage
• Hold brake + press five times = Switch zero/non-zero start
• Press nine times = Write NFC card

Can I use it for cargo hauling?

Yes, the G60 Pro includes a rear cargo rack with a 33 lb capacity, perfect for groceries, backpacks, or gear. The powerful motor and sturdy frame handle the extra weight with ease.

Are the tires inflated when it arrives?

The tires arrive partially inflated. You'll need to bring them up to the recommended pressure using the included bike pump before your first ride.

Frequently Asked Questions

What's the difference between the G60 and G60 Pro?

The G60 Pro features several major upgrades: a more powerful 1000W motor (vs 750W) with 2000W peak power, a larger 48V 25Ah battery (vs 20Ah) for 80+ mile range, puncture-resistant fat tires, NFC smart unlock system, and higher top speed of 36+ mph. The G60 Pro is designed for riders who want maximum performance and range.

How tall do I need to be to ride this bike?

The HappyRun Tank G60 Pro is designed for riders between 5'3" and 6'5" tall. The seat height is 34 inches, and the moped-style frame offers a comfortable, upright riding position for a wide range of body types.

Do I need to pedal at all?

No, pedaling is optional. The G60 Pro offers three riding modes: Pure Electric Mode (throttle only—no pedaling required), Pedal Assist Mode (motor amplifies your pedaling), and Manual Mode (ride like a traditional bike). You can switch between modes based on your preference.

How long does the battery last?

The 48V/25Ah battery provides 80+ miles of range per charge under optimal conditions. Real-world range varies from 35-80+ miles depending on terrain, rider weight, assist level, and riding style. The battery typically lasts 800-1,000 charge cycles (3-5 years of regular use).

How long does it take to charge?

The included 2A smart charger takes approximately 7-8 hours to fully charge the battery from empty. The removable battery design allows you to charge it anywhere—at home, in your office, or in your apartment.

Can I ride it in the rain?

Yes, the G60 Pro has an IP54 waterproof rating, meaning it's protected against water splashes from any direction. You can ride in rain and wet conditions, but avoid deep water, submersion, or pressure washing the electrical components.

How fast can it go?

The HappyRun Tank G60 Pro can reach speeds up to 36+ mph with pedal assist and throttle. Actual top speed depends on rider weight, terrain, battery level, and wind conditions.

Is it street legal?

E-bike laws vary by state and locality. The G60 Pro's high speed (36+ mph) may classify it as a Class 3 e-bike or moped in some jurisdictions, potentially requiring registration, licensing, or insurance. In many areas, you may need to limit speed to 28 mph for bike path access. Always check your local regulations before riding.

How much assembly is required?

The G60 Pro arrives 85% pre-assembled. You'll need to attach the handlebars and install the front wheel. Assembly takes approximately 45 minutes with the included tools. Tires arrive partially inflated and should be brought to proper pressure using the included bike pump.

What's the weight limit?

The maximum load capacity is 330 lbs, including the rider and any cargo. The rear rack can carry an additional 33 lbs of cargo.

What is the warranty?

The HappyRun Tank G60 Pro comes with a 1-year limited warranty covering manufacturing defects. For warranty service or questions, contact the manufacturer at service@happyrunsports.com. Eco Bikes USA provides full customer support for all purchases.

How do I switch between kilometers and miles?

Once the bike is unlocked, hold the brake lever and press the "S" button twice to toggle between kilometers and miles on the LCD display.

What are the hidden functions of the speed button?

The "S" button has multiple functions:

• Press and hold 1 second (power off) = Turn on
• Press and hold 2 seconds (power on) = Turn off
• Press once = Switch speed gears (1-5)
• Hold brake + press twice = Switch km/miles
• Press three times = Toggle trip/total mileage
• Hold brake + press five times = Switch zero/non-zero start
• Press nine times = Write NFC card

Can I use it for cargo hauling?

Yes, the G60 Pro includes a rear cargo rack with a 33 lb capacity, perfect for groceries, backpacks, or gear. The powerful motor and sturdy frame handle the extra weight with ease.

Are the tires inflated when it arrives?

The tires arrive partially inflated. You'll need to bring them up to the recommended pressure using the included bike pump before your first ride.
