These sampling trikes can be converted to house portable bars for sampling drinks. The trikes can be fitted with sunken ice chests, table-top display fridges and under-counter cool boxes for cold holding. This method is ideally suited for retail sales activation at any chain of supermarkets, convenience retailers or other stockists. Full portion samples can be given from the trikes, which are ideally suited for busy train stations, high streets or aligned events such as festivals, concerts or sports.
