The kit’s compatibility with 9-hole patterns broadens fitment for various wheel hubs, while the included mounting pads simplify alignment. Users should verify shaft diameter and chain compatibility prior to installation.
JRL Wheel Sprocket 32T
The JRL 32T sprocket is tailored for 49cc–80cc motorized bicycles using a 415 chain. It comes with a rear sprocket mounting kit and offers a CNC 3-hole option for additional installation flexibility. This model emphasizes compatibility with ball bearings in rear hub assemblies, and it supports standard mounting pads kits for reliable alignment and performance at varied RPMs.
DONSP1986 32 Teeth Sprocket
The DONSP1986 32-tooth sprocket features multiple hole patterns (9/6/3) and a long 135mm length for versatile mounting. Its center hole diameter is 37mm, designed to fit wide rear hub configurations and adapters for aluminum rims. It supports 415 chain compatibility and is intended for use with rear sprocket mounting pads and CNC sprockets, offering solid versatility for custom builds and performance upgrades.
CDHPOWER 32 Teeth Sprocket
The CDHPOWER sprocket provides multifunctional 32 teeth with 9/6/3-hole options and a 37mm center hole. It is compatible with 415 and 415H chains and aligns well with wheel hubs using a 9-bolt pattern. This makes it a solid choice for riders upgrading to higher performance gearing while maintaining broad compatibility with common rear hubs.
32T Sprocket 415 Chain by Cylemoto
Cylemoto’s 32T sprocket is specifically sized for 415 chains and is compatible with nine-hole mounting kits, rear sprocket mounts, and CNC 3-hole configurations. Its outer diameter and inner hole measurements are clearly stated to help buyers verify fitment for 49cc–80cc motorized bicycles, ensuring reliable installation and mount stability on standard rear hubs.
Flying Horse 2 Stroke/4 Stroke Motorized Bicycle 32 Tooth Rear Sprocket Replacement
Flying Horse’s 32-tooth rear sprocket aims at high-speed potential by reducing gear ratio compared to standard sprockets. It is designed for both 2-stroke and 4-stroke motorized bicycles, enabling faster cruising without engine strain. Installation is described as straightforward—replace the old sprocket with the new 32T unit. This option is particularly appealing for riders focusing on speed enhancements and efficient gearing for performance builds.
Buying Guide
Key considerations when selecting a 32T sprocket for a motorized bike include compatibility with the engine size (49cc–80cc), chain type (415 or 415H), and the hub mounting pattern (9-hole, 6-hole, or 3-hole). Assess the center hole diameter (commonly around 37mm for many 32T models) to ensure a snug fit on the rear hub. Consider whether you need additional mounting pads or a CNC adapter to match your wheel, as some kits require these components for precise alignment. Weight, durability, and material quality (steel or alloy) can affect long-term performance and resistance to wear. Finally, verify installation feasibility—some units include mounting kits, while others assume existing hardware. For riders chasing top-end speed, the Flying Horse and similar 32T sprockets can regear RPMs for faster cruising, but may demand engine tuning and proper venting to maintain reliability. For everyday riding, the DONSP1986, CDHPOWER, and JRL models offer versatile hole-pattern options and broad compatibility, making them suitable for a wide range of motorized bikes. Compare mounting options, hole counts, and chain compatibility to determine the best match for your setup.
