Hand-propelled vehicle ( 10 ) such as a pram or stroller has electrically-operated brake apparatus ( 13 ) which is applied automatically on a user releasing their grip from handle ( 12 ). Braking does not occur immediately grip or touch sensors ( 17 ) on handle ( 12 ) register that the user has released handle ( 12 ). Programmable controller ( 19 ) is provided which only applies brake ( 13 ) if sensors ( 16 ) detect movement of vehicle ( 10 ) and/or that vehicle ( 10 ) has moved more than a set distance subsequent to release of handle ( 12 ). Therefore braking apparatus ( 13 ) acts as a safety feature that only applies if, say, a vehicle is released on a slope and movement due to the slope is detected.
