Waw Specifications

Technical specifications

Frame: None; Self-supporting fibre structure

Cranckholder: Aluminium

Colour : As desired (RAL colours)

Rims: Aluminium

Weight (ca.): 29,5 kg

Lightning: As desired (options)

Turning circle : approx. 7,5m

Steering

Two steering wheels at the front, one driven rear wheel.

Front wheels: hard suspension (steel spring with friction damping in Aluminium McPherson; from Velomobiel.nl)
Tyres: maximum 40-406 (20"x1,5)
Brakes: drum brakes, separately used from each other

Rear wheel: no suspension
Tyres: maximum 60-559 (26"x 2,35)
Brakes: none

Steering is done by moving two handles next to the body.

Turning circle: approx. 8m

Gearing System

All existing gearing systems can be implemented in the WAW.

Standard is a derailleur system: three sprocket wheels at the front (32-42-52 tooth), nine sprocket wheels at the back (11-12-14-16-18-21-24-28).
Operating the gears goes with a DeoreLX dual control handle.
In combination with a 'top normal' derailleur is this system a comfort for changing gears.

Rohloff hub gear, Schlumpf Mountain drive or SRAM 3x9 can be implemented without any problem.

The standard crank length is 170mm, smaller cranks make pedalling faster (happy knees!) and more space for knees and feet.

Hood and Visor

In each WAW a hood, with visor, is included. The hood protects you from rain. Via the necessary ventilation cracks small raindrops can enter anyway. When standing still, there is no ventilation; opening the visor avoids it from steaming. Also when driving, the visor can be opened when visibility decreases.

Obviously, driving without hood is also possible; or the hood can be attached on top of the body. Test proves that this does not decrease speed or visibility.

Materials

The whole self-supporting structure is made from a mix of carbon and aramide fibrel with epoxy resin, approved for aviation industry.
The outer side is a very though epoxy coating, avoiding deep scratches and simplifying reparations.Most of the mechanical parts are in aluminium.

All WAW’s are paint-sprayed; colours can be chosen from these colour schemes:
-RAL
-MOTIP (including metallic colours). In fact; most car colours can be chosen.

For a supplement in price WAW’s can be paint-sprayed with a SIKKENS- paint, also with pearl effect.

Efficiency / Speed

Approx. 50 km/h for a 250 W capacity. Of course depending on the model (e.g. with or without hood), type of tyres etc.

(For your comparison: a sporty bike for daily use goes 33 km/h, a racing bike goes 37,5km/h).
On the website of Kreuzotter simulations can be made for different user conditions (uphill, wind,...). The WAW has the characteristics of a "streamlined trike".

Weight: in between 24 and 35 kg, depending on the model.

For use in hilly regions a BionX electric power assistance can be built in

Lenght of the drivers

Length:  between approx. 1m60 and 1m90. The critical places are around the feet and the knees. A lot of space can be won with the use of short cranks (e.g. 125mm instead of 170)
With 170 cranks a shoe size of 45 is the maximum.

Width:  the WAW is rather small, critical places are the shoulder width and between the wheel wells. In between the wheel wells come the thighs, here is 36 cm free space. Perfect shoulder width is 48cm.
