Supplier indexing describes the exact QS91 as a 20-inch carbon-frame and carbon-fork folding bike with 7-speed shifting. 江西轻鲨科技有限公司 is corroborated as a carbon-bicycle exhibitor; no complete weight, controlled clearance or stiffness result is transferred.

轻鲨 QS91-20 current option matrix
The current public index names 轻鲨科技 QS91 as a 20-inch carbon-fiber folding leisure bike. Its option matrix separately lists QS91-20 blue and QS91-20 blue with blue carbon wheels, matching the retained card. The index is used for model, wheel-size and selected-option identity only; it does not publish a controlled complete weight, folded dimensions, maximum clearance or stiffness result.
Light Shark QS91 supplier specification index
The current supplier index identifies the Light Shark QS91 as a 20-inch carbon-fiber folding bike with carbon-fiber fork, disc brakes and 7-speed shifting. It also associates Light Shark bicycle supply with Jiangxi Light Shark Technology Co., Ltd. Supplier prices and unrelated Light Shark models are not transferred, and no exact component maker, complete weight, clearance maximum or stiffness measurement is stated.
The public exhibitor directory lists 江西轻鲨科技有限公司 and describes its business as carbon-fiber bicycles. This supports the Chinese company attribution only; it does not establish QS91 specifications, purchase source authority, price, warranty or product availability.
Light Shark QS91 supplier specification index current recheck
Current supplier result names Lightb Shark QS91, a 20-inch folding bike with 7-speed transmission, carbon-fiber frame and fork, from Laiyi International Trade (Shandong). It is not a manufacturer source and does not identify component models or the selected JD color/wheel option.
轻鲨 QS91-20 JD index current recheck
Current JD image index names 轻鲨科技 QS91-20 and distinguishes blue from blue with blue carbon wheels, matching the selected-option identity. It does not link that listing to the legal manufacturer or publish a controlled component BOM.
