Lift

When the front wheel

of the bike enters the

water the surface water

is easily displaced as

spray. Just below the

surface, where the water

is under more pressure

from the volume of

water all around it, it is

not so easy to displace

and a wedge of high-

pressure water builds

up under the wheel,

providing lift to counter

the wheel’s weight.

The planing surface

uses the same kind of

pressure build-up seen

in the front wheel’s

‘wedge’ to provide lift.

Creating that pressure

is all down to maintaining

a constant thrust. If the

thrust drops the bike is

likely to nose dive into

the lake.
