KingBull Discover 2.0 & ST 2.0 Review: Long-Range, Heavy-Duty Fat Tire E-Bikes

KingBull Discover 2.0 & ST 2.0—powerful 750W motor, up to 100 km range, 400 lbs payload, and premium Shimano & Bafang components.

The KingBull Discover 2.0 & ST 2.0 are perfect for replacing short car trips, comfortable and speedy heavy-load carrying. Both have identical high-performance figures, with the only difference being the frame style; the Discover 2.0 comes with the diamond frame and the Discover ST 2.0 features the step-through design.

The discover 2.0 model brings several key upgrades compared to the discover 1.0. It now features a high-quality Samsung battery paired with a powerful Bafang motor for enhanced performance and reliability. The addition of a torque sensor offers a smoother, more responsive riding experience.

Design-wise, the new version boasts a sleek, rounded frame available in both step-thru and step-over styles, making it versatile and comfortable for riders of all genders. These thoughtful enhancements make the 2.0 a notable improvement over its predecessor.

These are built for serious riders with a 750W Bafang motor, 100 km max range, and a 400 lbs total payload capacity. They will be a good fit for both utility and endurance.

Is the Discover 2.0 & ST 2.0 for You?

Kingbull Discover E-Bike Review

The Discover 2.0 series is perfect for riders who:

  • Need a long range e-bike for commuting or weekend rides
  • Want the ability to carry heavy cargo or even a passenger
  • Prefer the stability offered by fat tires for riding on sand, snow, gravel, and city streets
  • Want the ability to flex between Class 2 legal limits and Class 3 performance unlocked

These e-bikes, and especially for city riders, will make commuting faster and easier. While the fat tires are an advantage, combined with the hydraulic brakes and sturdy frame, also make them reliable off-road for mixed rural terrains.

What We Appreciate About the Discover 2.0 & ST 2.0

1. Serious Range for Daily Use
With the Samsung 48V/720Wh lithium battery, you can ride up to 100 km. This is ideal for long commutes or weekend adventures where you don’t have to worry about recharging mid-ride.

2. Heavy-Duty Cargo Capability
The 400 lbs total payload capacity and 150 lbs limit for the rear rack means that groceries, work tools, or even a child seat can be carried without performance loss.

3. Rugged All-Terrain Tires
CST 26” × 4.0” puncture-proof fat tires provide grip on loose sand and even icy roads. This makes the bike usable all year round.

4. Premium Braking & Drivetrain
With dual pistons, the Zoom HB-875-E brakes provide reliable hydraulic disc brake action. We also enjoy the SHIMANO 7-speed drivetrain that provides smooth shifting while climbing steep grades or cruising on the flat roads.

5. Two Frame Options
You can choose a sporty standard frame or an easier step-through frame for effortless mounting and dismounting.

What We Don’t Like

Combined with a bike, a 77 lbs stated weight makes transportation and lifting a cumbersome task.

Hardtail Design: While fat tires assist, the lack of rear suspension dampening makes the ride on bumpy trails harsher compared to full suspension bikes.
