Product Overview: Built for the Future of Cycling

At Shuangye, we believe every ride should be seamless. Our frames are CNC-machined from premium 6061 aluminum alloy, offering an ideal balance of weight savings and structural integrity. The frame geometry is optimized for 26-inch to 29-inch wheels and accommodates mid-drive or hub motor systems with ease. A dedicated downtube battery compartment lets you integrate a 36V or 48V lithium pack cleanly, keeping the center of gravity low for superior handling. Every weld is TIG-welded and stress-tested to meet international safety standards, ensuring years of reliable performance.

From urban commuters to off-road adventurers, the Shuangye frame adapts to your vision. It features internal cable routing for a sleek profile, disc brake mounts (160mm/180mm), and a standard 68mm BSA bottom bracket. With a maximum rider weight capacity of 150 kg (330 lbs), this frame is built to carry you and your gear confidently.

Key Features That Set Us Apart

• Lightweight yet Robust: 6061 T6 aluminum alloy frame weighs only 2.8 kg (6.2 lbs) for the medium size, reducing overall eBike weight without sacrificing strength.
• Integrated Battery Mount: Clean downtube housing for most 36V/48V battery packs (up to 20Ah), with hidden wiring channels for a factory-built look.
• Universal Compatibility: Standard 68mm English threaded bottom bracket (BSA), 135mm rear dropout spacing, and 1-1/8 head tube – works with most hubs, motors, and forks.
• Enhanced Stability Geometry: 68° head angle and 450mm chainstays provide predictable handling at high speeds and during tight turns.
• Internal Cable Routing: Sleek external stops for brake and derailleur lines, plus a dedicated port for eBike motor cables – clean aesthetics and reduced snag risk.
• Corrosion-Resistant Finish: Multi-layer electrostatic powder coat in matte black, resistant to scratches, UV, and road salt.

Performance & Riding Experience

The Shuangye frame is designed to make every watt count. The stiff bottom bracket area ensures efficient power transfer from your motor to the rear wheel, while the relaxed geometry absorbs road chatter for a comfortable upright posture. On climbs, the balanced weight distribution prevents front-wheel lift, and on descents, the low center of gravity inspires confidence. The frame’s natural flex characteristics reduce fatigue on long rides, and the integrated battery mount keeps the weight centered for predictable cornering.

Whether you’re commuting at 20 mph or tackling off-road singletrack, the Shuangye frame responds precisely. Combined with a quality suspension fork (sold separately) and tires of your choice, this frame transforms into a capable e-MTB or city cruiser. The 135mm dropout spacing fits most geared hub motors and torque arms, while the standard BSA bottom bracket makes mid-drive installation straightforward.

Ideal Use Cases

DIY eBike Builders: If you enjoy selecting your own motor, battery, and components, the Shuangye frame is your blank canvas. It accommodates Bafang, Tongsheng, or CYC mid-drives as well as hub motors up to 1500W.

Urban Commuters: Pair with a 500W hub motor and a 48V 13Ah battery for a 30-mile range with pedal assist. The internal routing gives your bike a stealthy, theft-resistant appearance.

Off-Road Enthusiasts: Clearance for up to 2.4 knobby tires, plus disc brake mounts, make this frame ready for trail riding. Add a dropper post and aggressive treads for serious capability.

Cargo & Utility Riders: The sturdy construction supports rear racks and panniers (rack mounts not included but frame can be drilled). Use it for grocery runs or carrying gear.

Fleet Operators: Order in bulk for rental ebikes – the frame’s durability and simple maintenance reduce downtime.

Why Choose Shuangye?

We don’t just cut tubes and weld them together. Every Shuangye frame is designed with input from eBike engineers and tested by real riders. Our manufacturing follows ISO 9001 quality control, and each frame is individually checked for alignment, weld penetration, and finish. We offer a 2-year warranty against manufacturing defects (frame breakage or weld failure). Plus, our customer support team is ready to help with compatibility questions – just drop us a message.

Unlike generic no-name frames, the Shuangye gives you:

• Proprietary internal cable routing that works with both cable and electronic shifting.
• Replaceable derailleur hanger (compatible with standard RD hanger patterns).
• Integrated battery mount that fits most common Chinese battery packs without modification.
• Thoughtful porting for speed sensor, motor wire, and brake cut-off cables.

Safety & Warranty

Your safety is our priority. The Shuangye frame passes the EN 15194 (European eBike) and ISO 4210 (general bicycle) standards for structural integrity and fatigue resistance. All edges are deburred, and the powder coating is free of heavy metals. Proper installation by a qualified mechanic is required; we recommend torqueing all bolts to manufacturer specifications and using locktite on critical fasteners.

Warranty: 2 years against manufacturing defects. This covers material or workmanship issues, including cracked welds and bent dropouts under normal use. Do not exceed the maximum rider weight (150 kg) or use with motors over 1500W continuous for extended periods. The frame is not warrantied against crash damage, modifications, or improper assembly.

Frequently Asked Questions

Q: Will this frame fit a Bafang BBS02/BBSHD motor?
A: Yes, the BSA 68mm bottom bracket is directly compatible with Bafang mid-drive units. You’ll need the proper lock-nut and spacer kit included with your motor.

Q: What size battery can I fit in the downtube?
A: The internal compartment measures 410mm x 80mm x 60mm (L x W x H). It fits most 36V/48V batteries up to 20Ah with Hailong or shark-style cases. Custom batteries can be ordered with the same footprint.

Q: Does the frame come with a rear derailleur hanger?
A: Yes, one replaceable hanger is included. Spare hangers are available separately.

Q: Can I use this frame with a 1500W direct drive hub motor?
