How this e-bike scores for different riding styles

High Performance
98/100

The 5000W peak dual motor system, 36 mph top speed, 85+ mile range, and exceptional torque delivery make this one of the highest-performance e-bikes available for speed enthusiasts seeking maximum capabilities.

Off-Road Adventure
95/100

With 5000W peak dual motors, full suspension, 20-inch fat tires, hydraulic disc brakes, and exceptional climbing ability, this bike is engineered specifically for challenging off-road terrain and trail riding.

Cargo & Utility
85/100

The 330 lb weight capacity, dual-seat design with swappable cargo rack, dual 38Ah battery system, and powerful motors make this excellent for hauling groceries, equipment, or passengers with ease.

Recreational Leisure
70/100

The dual-seat configuration, comfortable full suspension, and long 85+ mile range make it suitable for leisurely family rides, though the aggressive off-road design and weight may be overkill for casual cruising.

Daily Commuting
65/100

The 85+ mile range and dual batteries are excellent for commuting, but the lack of UL certification, heavy weight, and 36 mph top speed make it less ideal for typical urban commuting where lighter, more practical bikes excel.

Compact & Portable
15/100

Not foldable and likely very heavy due to dual motors, dual batteries, and robust steel frame. This bike prioritizes power and durability over portability and is unsuitable for apartment storage or public transit.

Our Verdict

The HAPPYRUN G70 Pro is a beast of an electric bike built for people who want serious power and long-distance capability. With two motors putting out 5000 watts combined, this bike can zoom up to 36 miles per hour and climb steep hills that would stop most other e-bikes. The dual battery system holds 38Ah total and gives you over 85 miles of riding on a single charge, which is more than almost any other e-bike out there. The fat tires and full suspension make bumpy dirt trails feel smooth, and the hydraulic brakes stop you safely even at high speeds. At $1,699, you get a lot of power and features for the money compared to other high-performance e-bikes.

This bike works best for people who want to ride off-road on trails, dirt paths, and rough terrain. The powerful motors and fat tires let you go places regular bikes cannot handle. It is also great if you need to carry heavy stuff or want to ride with a passenger, since it holds up to 330 pounds and comes with two seats. The cargo rack option makes shopping trips easy. Families who want to take their kids on rides or people who need to haul equipment for work will find this very useful. The 85-mile range means you can take long adventures without worrying about the battery dying.

However, this bike is not right for everyone. It is very heavy and does not fold, so you need a garage or large storage space. If you live in a small apartment, this bike will be hard to keep. It also lacks UL safety certification, which some buyers want for extra peace of mind. The bike has no pedal assist, so you cannot get exercise while riding like you can with most e-bikes. If you mainly ride on smooth city streets and just need something to get to work, a lighter and simpler e-bike would probably work better and cost less. This bike is really made for people who need maximum power and want to go off-road or carry heavy loads.

What We Like

  • Extremely powerful 5000W dual motor system with 2500W per motor delivers outstanding torque and can tackle any hill or terrain with ease
  • Huge 38Ah dual battery setup gives you 85+ miles of range so you can ride all day without worrying about running out of power
  • Can carry up to 330 pounds and comes with two seats or a cargo rack, making it perfect for riding with a passenger or hauling heavy loads
  • Full suspension with front fork shocks and seat absorber plus fat tires smooth out bumpy trails and rough roads for a comfortable ride
  • Smart NFC unlock and app connectivity let you start your bike with a tap and track its location from your phone

What Could Be Better

  • Very heavy bike due to dual motors and batteries, making it difficult to move around, lift, or transport when not riding
  • Does not have UL safety certification which some buyers may want for peace of mind about electrical safety standards
  • Cannot fold up for storage, so you need a full garage or large space to keep it when not in use
  • No pedal assist mode means you cannot get exercise while riding and must rely entirely on the throttle for power
  • Has zero customer reviews yet so there is no real-world feedback about reliability or how well it actually performs
