A New Chapter for HITWAY E-Bikes
HITWAY is entering a new chapter with the introduction of its new U Series and S Series-four new e-bikes designed to offer riders more choice in how they ride.
As e-bikes become an increasingly practical part of everyday mobility, riders are looking beyond basic specifications. Comfort, responsive assistance, control and everyday practicality are becoming just as important as motor power and battery capacity. At the same time, different riders have different expectations from their e-bike.
Some may prefer a straightforward and versatile riding experience, while others may want assistance that responds more directly to their pedaling or a more refined riding setup.
That is why HITWAY is expanding its new lineup around two distinct e-bike platforms: the U Series and the S Series.
The U Series is built around a rear-hub motor platform, while the S Series introduces a mid-drive motor platform. Within both series, riders can also find different pedal-assist technologies and configurations, creating four distinct models: BK-U2, BK-U3, BK-S2 and BK-S3.
From practical everyday riding to a more responsive and refined experience, the new lineup is designed to give riders more meaningful choices — without making the choice itself complicated.
Let’s take a closer look at the new HITWAY U Series.
Meet the New HITWAY U Series
The new HITWAY U Series is built around a rear-hub motor platform.
The series focuses on practical, versatile riding while offering different levels of power, battery capacity and riding characteristics.
Within the U Series, riders can choose between the BK-U2 and BK-U3 — two e-bikes that share the same rear-hub motor concept and torque-sensing assistance, while offering different riding experiences.
HITWAY BK-U2
The HITWAY BK-U2 is designed as a practical all-round e-bike for riders who value everyday usability, balanced performance and a comfortable, straightforward riding experience.
Its 250W rear-hub motor with 39 Nm of torque works with a torque sensor, delivering assistance that responds to the rider's pedaling effort for a more natural and controlled riding experience.
The U2's 29 × 2.25-inch puncture-resistant tires are designed around a stable and versatile riding experience, making the bike suitable for everyday city rides, commuting and longer recreational journeys.
With a 36V 14Ah / 504Wh removable battery, the U2 offers a range of up to 150 km, depending on riding conditions.
It also comes equipped with:
- Shimano 7-speed gearing
- 100mm front suspension
- Air Dropper Seatpost
- Front and rear hydraulic disc brakes
- Rear rack
- Up to 150 kg maximum payload
The idea behind the U2 is simple: a practical and well-balanced e-bike that makes everyday riding easier, more comfortable and more versatile.
HITWAY BK-U3
The HITWAY BK-U3 takes the U Series in a more powerful and versatile direction.
Like the U2, it uses a 250W rear-hub motor with a torque sensor, but the U3 steps up to a 48V system with 55 Nm of torque, providing stronger motor performance for riders who want a more capable riding experience.
The U3 also brings a larger 48V 15Ah / 720Wh removable battery with LG 21700 cells, supporting a range of up to 175 km.
Its 27.5 × 2.8-inch puncture-resistant tires give the bike a different character from the U2, with a wider setup focused on stability, comfort and confidence across a wider variety of everyday riding surfaces.
The U3 also adds:
- Shimano 7-speed gearing
- 100mm front suspension
- Air Dropper Seatpost
- Front and rear hydraulic disc brakes
- Front rack mounting and rear rack
- Up to 150 kg maximum payload
The U3 is therefore aimed at riders who want to stay with a rear-hub motor while stepping up to higher motor torque, a larger battery and a wider tire setup for longer rides and more versatile everyday use.
Meet the New HITWAY S Series
The HITWAY S Series takes a different approach.
Instead of placing the motor in the rear wheel, the S Series uses a mid-drive motor, creating a different riding experience from the rear-hub platform.
By positioning the motor closer to the center of the bike and combining it with torque-sensing pedal assistance, the S Series is designed to deliver a more natural and responsive connection between the rider and the bike.
The S Series includes the BK-S2 and BK-S3. While both models share the same mid-drive platform and core riding technology, their different frame designs and cockpit configurations give each model its own character.
HITWAY BK-S2
The HITWAY BK-S2 combines the Bafang M430 250W mid-drive motor with a torque sensor, delivering assistance that responds to how much effort the rider puts into the pedals.
With 120 Nm of torque, the S2 is designed to provide strong and responsive assistance across everyday rides, longer journeys and more demanding routes.
Its 48V 15Ah / 720Wh LG 21700 battery provides a range of up to 175 km, while the included 7.5A fast charger can recharge the battery in approximately 1.5–2 hours.
The S2 uses 27.5 × 2.2-inch Kenda puncture-resistant tires with reflective strips, combined with a 100mm air suspension fork with lockout and an air dropper seatpost for a more controlled and comfortable ride.
The S2 also includes:
- Shimano 7-speed gearing
- Tektro 180mm hydraulic disc brakes
- Integrated front and rear lights
- Rear rack
- Up to 150 kg maximum payload
With its integrated handlebar and longer frame, the S2 is designed for riders looking for a comfortable and practical mid-drive e-bike with a broad everyday riding range.
HITWAY BK-S3
The HITWAY BK-S3 shares the same core technology as the S2, including the Bafang M430 mid-drive motor, torque sensor and 48V 15Ah / 720Wh LG 21700 battery.
Rather than changing the motor platform, the S3 takes a different approach through its overall bike design.
Its 27.5 × 2.2-inch Kenda puncture-resistant tires, 100mm air suspension fork with lockout and air dropper seatpost provide a balanced setup for everyday riding, while the Tektro 180mm hydraulic disc brakes provide controlled braking performance.
The S3 also includes:
- Shimano 7-speed gearing
- 7.5A fast charger with approximately 1.5–2 hours charging time
- Integrated front and rear lights
- Rear rack
- NFC
- Up to 150 kg maximum payload
Compared with the S2, the S3 features a shorter and wider frame and a handlebar with a separate stem, creating a different riding position and overall bike feel.
The S3 is therefore suited to riders who want the same high-torque mid-drive platform and long-range capability while preferring a different frame geometry and cockpit design.
What Can Riders Expect from the New HITWAY Lineup？
The new U and S Series represent more than an expansion of HITWAY's product range.
They reflect a broader approach to the riding experience.
More Natural Assistance
With both cadence-sensor and torque-sensor options across the range, riders can choose how they want motor assistance to respond to their pedaling.
Improved Riding Comfort
From large 29-inch wheels on the U2 to wide 27.5 × 2.8-inch tires on the U3, and from standard suspension to the air suspension fork with lockout on the S3, different models are designed around different comfort needs.
More Control
Hydraulic disc brakes, suspension systems, 7-speed gearing and different tire configurations give riders practical tools for controlling the bike across everyday riding conditions.
More Refined Riding Experiences
The combination of rear-hub or mid-drive motors with cadence or torque sensing allows the new lineup to cover a wider range of riding preferences.
More Practical Everyday Use
Rear racks are included across the four models, while selected models add features such as front basket mounting, mudguards, APP connectivity and NFC.
The goal is not simply to add more features.
It is to give riders more meaningful choices.
Discover the New HITWAY U and S Series
The new HITWAY U and S Series are designed to give riders more ways to find an e-bike that fits their everyday needs and preferred riding experience.
If you are looking for a practical rear-hub e-bike, the U Series offers a versatile starting point. If you are interested in a mid-drive riding experience, the S Series provides another approach.
Within each series, riders can also choose between different pedal-assist technologies and configurations — from the straightforward BK-U2 and BK-S2 to the more responsive BK-U3 and BK-S3.
But this is only the beginning.
In the upcoming HITWAY articles, we will take a closer look at the technologies behind the new lineup, explore the differences between rear-hub and mid-drive motors, and explain how cadence and torque sensors can change the way an e-bike feels to ride.
The new HITWAY U and S Series are coming. Stay tuned to discover more.
