HYPERAX Step Thru e Bike Adapter Fits Up to 70 lbs - Secure Step-Thru

In this review the HYPERAX Step Thru e Bike Adapter proves to be a simple, practical solution for transporting step-thru and folding e-bikes on hanging hitch racks. The bottom line: this adapter is for riders who need a reliable way to hang heavier step-thru e-bikes without modifying the bike or rack, and its biggest selling point is the protected, co-molded rubber hooks that prevent contact damage while holding up to 70 lbs. Installation is straightforward and the adapter is built for repeated use rather than occasional one-off trips.

Key Features

• Co-molded soft rubber hooks: The hooks cushion the handlebar and seat stem, preventing scratches and abrasion during transport.
• Convenient clamp design: The clamp secures the adapter to a bike frame quickly, making installation and removal fast and tool-free in most cases.
• 70 lb capacity: Rated to hold up to 70 lbs, it accommodates many popular step-thru e-bikes and folding models used with hanging racks.
• Rack compatibility: Designed to work with multiple hitch bike rack systems so users can adapt existing racks rather than replace them.
• Durable construction: Customers note the adapter feels sturdy and heavy-duty in hand, which supports repeated use and travel.

Who It's For

This adapter is aimed at owners of step-thru and folding e-bikes from brands like Lectric, Rad Power, Aventon and similar models who use hanging-style hitch racks and need a protected contact point for safe transport. It is particularly useful for riders who want a compact, portable solution to lift their bike by the frame without modifying the bike.

Riders who prefer platform-style racks, have very heavy cargo bikes above 70 lbs, or need an integrated locking hitch system should look elsewhere; the adapter is intended to add functionality to hanging racks rather than replace a full platform carrier or frame-specific mount.

Pros & Cons

Pros

• Protects handlebars and seat stem with soft, co-molded rubber hooks.
• Simple clamp design makes installation and removal quick and accessible.
• Compatible with multiple bike rack systems, increasing flexibility for different racks.
• Customers report solid build quality and sturdiness suitable for frequent use.

Cons

• Lockability feedback is mixed; some users find it secure while others note the adapter does not lock in place by itself.
• Capacity limited to 70 lbs, so heavier cargo e-bikes or bikes with accessories close to that weight may require a platform rack.
