About the Discover ST 2.0
The Kingbull Discover ST 2.0 is the step-through variant of the Discover 2.0 series, sharing the identical motor, battery, and component specification while offering a lower, accessible frame profile that makes it ideal for urban commuters, riders with joint concerns, and anyone who frequently mounts and dismounts in traffic. The 26×4.0-inch fat tires, 80mm suspension fork, and 750W torque-sensing Bafang motor deliver genuine all-terrain capability from a frame that prioritizes ease of use. Available in pink, white, and space gray.
Technical Specifications
| Motor | 750W Bafang Brushless Hub (1,300W Peak, 80Nm) |
| Battery | 48V 15Ah Samsung (720Wh) |
| Range | Up to 60 Miles |
| Weight Capacity | 400 lbs |
| Bike Weight | 77 lbs |
Pros
- ✅ Low-step frame geometry enables effortless mounting and dismounting in stop-and-go traffic without the joint strain of swinging a leg over a high top tube
- ✅ Torque sensor system provides smooth, proportional pedal assist that responds immediately to pedaling effort—significantly more natural than the cadence sensors typical in this price range
- ✅ The 26×4.0-inch CST all-terrain tires provide stability and confidence on wet pavement, loose gravel, and light dirt paths that would challenge narrower tire commuter bikes
Cons
- ❌ Step-through frames are marginally less torsionally stiff than equivalent step-over designs, which some experienced cyclists may notice as slight flex through tight corners at speed
- ❌ Real-world range at PAS 4 or 5 on hilly terrain is closer to 39 miles than the 60-mile headline figure; riders on very hilly commutes should plan charging accordingly

Frequently Asked Questions
I am 5’1″ and was told by another reviewer that e-bikes with 26-inch wheels are usually too large—will the Discover ST 2.0 fit me?
The Discover ST 2.0 is compatible with riders from 5’1″ and above due to its step-through frame and adjustable seatpost with 18 inches of travel range (minimum seat height of 32.2 inches, maximum of 40.1 inches). At 5’1″, most riders can comfortably flat-foot or near-flat-foot at traffic stops thanks to the low stand-over height of the step-through frame. Kingbull’s own guidance confirms the minimum recommended height is 5’1″.
Is the Discover ST 2.0 suitable for a 200 lb rider on a daily commute with moderate hills?
Yes. The bike is rated for a total payload of 400 lbs, so a 200 lb rider is well within the structural limits. The 750W Bafang motor produces 80Nm of torque and is rated for climbs up to 35 degrees, which covers virtually all urban and suburban inclines. At PAS 3 with a 200 lb rider on moderate hills, expect real-world range between 35 and 45 miles per charge—enough for most urban round trips.
