Body length without nose and tail : approx. 1,8m
Length without nose and tail incl cranck axle and wheel holders 2,1m
Height from ground to bottom 0,1m
Track width 0,75m
Body width 0,70m
Wheel base 1,30m
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 : maxium 40-406 (20"x1,5)
brakes: drum brakes, separately used from each other
Rear wheel : no suspension
tyres : maximum 60-559 (26"x2,35)
brakes : none
Steering is done by moving two handles next to the body.
Turn radius : approx. 8m
All existing gearing systems kan 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 controll handle. In combination with a ‘top normal’ derailleur is this system a comfort for changing gears.
Rohloff hub gear, Schlumpf Mountaindrive or SRAM 3×9 can be implemented without any problem.
The standard cranck length is 170mm, smaller crancks make pedalling faster (happy knees !) and more space for knees and feet.
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 WAWs are paint-sprayed; colours can be choosen from these colour schemes :
-MOTIP (including metallic colours). In fact; most car colours can be chosen.
For a supplement in price WAWs can be paint-sprayed with a SIKKENS- paint, also with pearl effect.
In each WAW a hood, inclusive 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 hood can be attached on top of the body. Test prove that this does not decrease speed or visibility.
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 characteritics 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 crancks (e.g. 125mm instead of 170)
With 170 crancks is shoe size 45 maximum .
Width : The WAW is rather small, critical places are between the wheel wells and shoulder width. In between the wheel wells come the thighs, here is 36 cm free space. Perfect shoulder width is 48cm.
