CILOYU Mini Bike Axle Kit for Coleman CT100U — 12mm x 270mm Rear & 225mm Front, Hardened Steel

The CILOYU CT100U axle kit is a complete mini bike wheel axle replacement set featuring a 12 mm x 270 mm rear axle and a 225 mm front axle designed for Coleman CT100U models.

If your Coleman CT100U mini bike shows signs of worn or bent axles, this CILOYU kit supplies the key components needed to restore wheel alignment and stability. Crafted from hardened steel with a smooth finish, the set includes both rear and front axles plus the nuts, bolts and gaskets required for a straightforward swap. The parts are sized and boxed for CT100U fitment, though the rear axle’s length may require trimming or modification for some other minibike frames.

Will this axle kit fit my Coleman CT100U mini bike?

The kit is built specifically to match the Coleman CT100U wheel spacing and mounting style, with a 12 mm diameter rear axle and a 270 mm length that aligns with the stock wheel hub. Front axle dimensions are 225 mm in length. If your minibike is a CT100U, installation typically fits without additional parts.

• Rear axle: 12 mm diameter, 270 mm length (0.47" × 10.63").
• Front axle: 225 mm length (8.85").
• Included hardware: axle nuts, bolts and gaskets for mounting.
• Compatible primarily with Coleman CT100U stock configuration.

How durable and smooth are the axles for everyday riding?

CILOYU manufactures the axles from premium steel and polishes the surfaces to reduce friction where bearings and wheel hubs meet. The improved finish helps wheels spin more freely and resists premature wear under normal recreational use. Proper installation and routine checks will extend service life.

• Material: hardened steel for strength and wear resistance.
• Polished axle surface reduces friction on bearings and seals.
• Supplied hardware protects threads and improves sealing.
• Recommended: inspect torque and alignment after initial miles.

What tools and steps are needed to install the axles?

Replacing the axles requires basic tools: sockets or wrenches matching the provided nuts and bolts, a torque wrench for accurate tightening, and possibly a cutting or grinding tool if axle length needs adjustment for non-CT100U frames. The process is a standard wheel removal, swap the old axle for the new one, fit gaskets and hardware, and torque to manufacturer specs.

• Tools: socket/wrench set, torque wrench, pliers, optional cutting tool.
• Steps: remove wheel, extract old axle, insert new axle, secure nuts/gaskets, verify alignment.
• Tip: measure brake and chain clearance before finishing torque.
• Modification: rear axle may need shortening for some minibike frames.

Can I use this axle kit to upgrade or modify other minibikes?

The kit can serve as a repair or modification part for various small frames, but the rear axle’s 270 mm length is longer than some models expect. For non-CT100U bikes you may need to trim the axle or change spacers to achieve proper wheel spacing. Always confirm hub width and chain/brake fitment before cutting metal.

• Suitable for custom projects where 12 mm axle diameter is required.
• Rear axle may be trimmed for narrower frames—measure twice before cutting.
• Adjust spacers and gaskets to maintain brake and chain alignment.
• Works well as a stable replacement for worn original axles.

Who is this for: The CILOYU CT100U axle kit is aimed at Coleman CT100U owners who need a direct replacement for damaged wheel axles, DIY mechanics restoring minibikes, and small-shop technicians looking for a durable steel axle set that reduces friction and restores wheel stability. If you’re repairing your CT100U or building a compatible mini project and want OEM-style dimensions with rugged construction, this kit delivers the primary components and mounting hardware to get wheels back in safe, smooth rotation.
