With its 70 Nm motor, long-lasting battery and CE and TÜV certifications, it appeals to cyclists looking for a bike capable of tackling city streets as well as trails, snow, sand or gravel.

Who is this bike for?

This model is particularly suitable for:

• Daily urban and suburban journeys (10 to 30 km/day)

Performance and range

The HITWAY BK10S is equipped with a 250 W hub motor delivering an impressive 70 Nm torque, compliant with European regulations. This high torque allows sharp acceleration and excellent climbing ability, ideal for urban hills and rough trails.

• Claimed range: 60 to 120 km (depending on assistance mode)
• Real-world range: approximately 45 to 80 km depending on use
• Maximum assisted speed: 25 km/h (EU standard)
• Climbing ability: up to 25°

In real-world conditions, range depends on:

• Rider weight (max load 120 kg)
• Chosen assistance mode
• Terrain (flat vs climb, road vs trail)
• Weather conditions and tyre pressure

The 48 V 13 Ah (624 Wh) lithium-ion battery is concealed within the bike frame, offering both increased security and clean aesthetics. Removable after folding, it recharges easily at home or in the office in 6.5 hours, without having to move the entire bike.

Design and comfort

The BK10S focuses on versatility and robustness. Its aluminium alloy frame weighs 33.2 kg battery included, offering a good balance between solidity and portability. Its foldable design allows compact storage (99 × 53 × 75 cm when folded), ideal for confined spaces, car boots, SUVs, camper vans or boats. The bike suits riders between 165 and 195 cm tall.

Its 20 × 4.0 inch anti-slip and puncture-resistant pneumatic tyres offer excellent grip and stability on all terrains: asphalt, sand, snow, gravel or muddy trails. The front suspension fork effectively absorbs shocks on uneven surfaces, guaranteeing superior riding comfort on rough trails.

For braking, front and rear mechanical disc brakes offer powerful and consistent braking, reliable even in rain or on descents. The Shimano 7-speed transmission efficiently manages terrain and adapts pedalling to the desired rhythm.

The multifunctional LCD display with Bluetooth connectivity allows real-time monitoring of speed, mileage and range, and connects to the HITWAY app to customise settings and track journeys. StVZO-certified front and rear LED lights, IP54 waterproof rating and CE/TÜV certifications complete the equipment for optimal daily safety.
