⚡ At a Glance
- • Build Quality: High-strength aluminium alloy construction, double-layer wheel design, lightweight and corrosion-resistant
- • Best for: E-bikes and snow bikes that use 20-inch wide tyres and need a sturdy replacement rim
- • Not ideal for: Buyers who require a complete wheel build, as hub, spokes and tyre are excluded
Approximately 50.8 cm diameter and 8 cm width with a 36-hole pattern and AV valve layout. Supplied as a single 20 x 4.0 rim intended as a replacement for wide-tyre wheel builds.
Stable Wide-tyre Support - with 20 x 4.0 rim dimensions
Measured at about 50.8 cm (20 inches) diameter and roughly 8 cm width, the profile matches common fat-tyre specifications. The 36-hole drill pattern and AV valve cut-out accommodate fat-bike tube setups.
Better flotation and traction on loose ground or snow for riders using wide tyres. Suitable when a robust rim is needed to carry heavier loads or low-pressure tyres.
Durability and Low Corrosion Risk - thanks to aluminium alloy construction
Manufactured from a high-quality aluminium alloy described as strong and lightweight, with a finish designed to resist rust. Double-layer wheel construction is noted in the product title.
Reduced maintenance and longer service life in wet or salty conditions compared with untreated steel. Durable construction suits repeated use on e-bikes and utility fat bikes.
Straightforward Wheel Building - with 36 holes and AV valve layout
Hole spacing accepts 12g spokes, though final spoke length requires testing against the chosen hub. Package contents list one rim only; hub, spokes and tyre are excluded.
Experienced wheel builders can match the rim to standard 12g-spoke setups for reliable wheel builds. Buyers should measure spoke length and source matching components before assembly.
