1896 Leon Bollée Tricar, 3½ hp
It would seem that on this year's run, the entrants were numbered by age, so the Dreadnought didn't get Number 1. That was reserved for the oldest vehicle on the run, shown here - 102 and still going strong.
The tricar was quite popular around the turn of the century, as motorcycles at this time were still rather unsafe due to the unlikely engine positions chosen by many designers. This style features possibly the earliest example of a front crumple zone, also known as a "passenger" - this one looks remarkably relaxed, considering the state of the Brighton traffic.
