Borealis V3 Progress

I have been riding the Borealis V3 for some time now.  This first one was built using carbon/vectran hybrid material for the outside layer and kevlar as the inside layer.  It ended up a bit heavier than I had hoped but its quite robust.  It will be able to survive lots of abuse.  With suspension all round it is still under 80 pounds.

This one has front suspension.  I would keep the front suspension but if you were going for the lightest weight possible I would get rid of it.  If you have the choice of having suspension on the rear wheel or the front wheels for comfort choose the rear wheel.  While the front suspension gives you some good feed back for cornering the rear helps the velomobile be more comfortable and quiter.    I have a WAW to compare to which has front and not rear suspension.  The crom-moldy frame of the QNT trike in my V2 soaks up some bumps so this may not be a completely fair comparison. 

Some of the improvements on the V3 are going to be incoporated into the V2.  The new signal controller is much simplier and more robust.  It now uses relays for the signal lights and has mostly soldered connections.  The running lights can be left on  or they can be turned off to conserve power as the lights come on instanly when you restore power.  Before the chip in the contol module had to boot up first and this took a few seconds.  The wheel fairings developed for the V3 will fit the V2.  The bulkhead and rear fender for the V3 will also work in the V2 as they are a lighter and better way of attaching the rear of the trike to the fairing. 

 I can now finally see how the finished product will be.  Once the new rear fender is done we will be able to take orders.
