Thickened-Rubber 20-Inch Stabilisers

Engineered for safe, controlled progression on 20-inch children’s bicycles, these stabilisers combine structural rigidity with surface-adaptive traction. The wheel assembly uses a thickened rubber layer bonded over a rigid plastic hub — resistant to cracking, flattening, or tread separation after repeated use. The support arms are formed from cold-rolled steel with corrosion-resistant coating suitable for UK’s variable climate. Mounting hardware includes stainless M6 bolts and lock washers. Compatible with rear wheel diameters from 18 to 22 inches; recommended height adjustment range allows incremental lowering from full support to near-ground clearance for final balance transition.
