Bought to replace the bell on the b’twin 14” child’s bike as that bell never worked , (bike also never came with the front mudguard). The bell can not be tightened enough to grip the handlebar and would need a rubber spacer to work
Thank you for passing on this information regarding the diameter of the bar required to fit this bell. This bell is designed for bars greater than 22mm in diameter (not oversize). The bars on the 14" bikes 19mm in diameter and a rubber shim will be required in this case.
We sell models which will fit such as this one: https://www.decathlon.co.uk/mistigirl-childrens-bike-bell-id_8303175.html
