A Foldable Bike Trainer in Riding and Storage Positions: HS-QX-003AKL
See the HS-QX-003AKL foldable bike trainer in its riding and stored positions, and check the bicycle connection and space needed for each.
The Hongsen HS-QX-003AKL is a foldable bike trainer for indoor riding with the rear wheel in place. Its floor tubes spread apart in the riding position and sit alongside each other in the folded position. The magnetic resistance unit stays attached to the frame, so a buyer can compare the complete stored shape with the space available between rides.
The open frame supports the bicycle at the rear axle
In the riding view, the frame has two triangular side sections above the floor tubes. Opposing supports meet the bicycle at the rear axle. Below them, a roller meets the rear tire; the wheel stays on the bicycle while it turns the roller.
The axle supports and roller meet different parts of the bicycle. For a planned indoor riding space, consider the room taken by both the open frame and the bicycle. The rider also needs space around the complete arrangement.
The 2026 catalogue lists steel with a magnetic motor for HS-QX-003AKL and gives a size field of 26 to 29 inches. Ask Hongsen to confirm the rear-axle connection for the intended bicycle when selecting the trainer.
The folded frame keeps the resistance unit attached
The folded view shows the two floor tubes alongside one another. The upper axle supports remain on the frame, while the resistance unit remains attached at the other side of the assembly.
The resistance unit projects beyond the tubes in this view. When choosing a storage position, compare the available space with the complete folded unit. Request the current folded dimensions for the exact model before specifying a storage space.
Review both positions for the intended bicycle
A buyer selecting a foldable trainer can check two sets of information. For the riding position, provide the bicycle’s wheel size and rear-axle details. For storage, request the folded dimensions and compare them with the planned space. Keep the full HS-QX-003AKL model name on both requests.
See the HS-QX-003AKL product page and the Hongsen indoor trainer range. Contact Hongsen with the bicycle and storage requirements.
