i like the shape and roll cage .... are we still talking pedal tricycle ?

A elec. assisted tadpole pedal trike with similar shape is my vote

Also there is the Bug E ... just add pedals

But for a pedal machine you need to move the driver/peddler forward with knees near the front wheels

as in the Go One

I'm surprised nobody has suggested a flexible, fabric skin velomobile body - like the concept BMW GINA. You wouldn't necessarily need to have it capable of changing shape, but a simple fiberglass, CF, or aluminum rod framework with a durable lycra-like fabric would make a simple and aerodynamic body. If one wanted a more permanent solution, one could simply give it a couple of good layers of spray epoxy.

OK... I'll give you that one - the concept is somewhat similar. However, the execution is miles apart, and the VeloKit lacks quite a lot of sex appeal.......... :mrgreen: :wink:


Which velo-skin would you prefer to wear?


This...........?

Here's my electric assist fulls suspension tadpole & trailer with a little weather protection, 1000 lb max payload capacity and seating for two passengers. Looked into doing solar roof panels but don't yet believe it very cost effective or practical. However, it is easy to find power in an urban environment so I just carry a tiny 350 watt charger and plug in when I must.

Maybe a light weight roll cage frame that would incorporate a light weight roof and front aero ?? but still be easy to get in and out of ??

Also some roll over protection and side impact

might look like this but for a tadpole ... http://goblinmotors.com/html/goblinaero ... le__c.html

Well, Michael, that little Bimmer logo means unobtanium. The Velo is about 750 USD. It ain't very pretty but does do the job. In fact, I would consider it if I had to commute in cold weather. I don't! It is light weight and keeps the rain off and the wind from slowing one down as much. Seems like a fair tradeoff for ugly!

Doc,

It's pretty all right...pretty f'ing ugly! Looks like horrible aero too.

Here's a method I've been toying with for building a super light, easily repairable, and aerodynamic faring. If a seaworthy canoe can weigh 8lbs, imagine how light a no load bearing structure could be, since most of the canoe's weight is in the framing. http://www.gaboats.com

Wow, John! Great minds do think alike! I saw that website a while ago and it reminded me of my Cleveland Model kits that I used to build. I'm way short on patience for that kind of thing now, but it sure is eiegant and light! Way kool! You have the same problem that I do regarding heat. I could only use a fairing or enclosure a few weeks of the year. It is to dam* hot!

I do not think the a frame covered with stretch material would work. In any sort of accident, it would be torn/ripped/melted open leaving you exposed to the roads surface. As someone who has slide a velomobile on its side for 12 metres with no protection, that situation is never going to end well. In the past, we used to use shrink wrap to enclose our vehicles, which would work but would be damaged easily.

Below is a picture of this years trike. This was powered by a 31cc Honda and pedals after the electric motors speed controller kept blowing up :evil: forcing us to shelve the elecric motor for this year until I can come up with something more reliable.

Dude, elio motors needs to start bringing that to market. I'm thinking it might be much better for me to modify an existing base than to create my own, especially if I plan to use it for "high speed", long distance trips. And that base looks pretty attractive at that price. I really care about the aerodynamics for long distance trips, and long distance trips only seem time-wise practical at higher speeds. For within the town trips, aerodynamics isn't as much of an over-riding concern as the needed battery capacity is fairly small and I already have that spectrum "covered" (Mostly).

Let's raise this thread from the dead. I'd love to live car free, and do mostly with my two bikes and my walking shoes, but to be able to sell my car I need the ability to carry a passenger and ride in the rain. The enclosed tadpole with a passenger seat right behind the driver would do it for me too. Full suspension, big motor (likely a cromotor) to handle the passenger weight, and loads of batteries for those 100 mile days.

Wish I knew how to weld, it's something I'll have learn I think. I love the look of this trike, it has front suspension, and 3 seats in fact. I'd want full suspension for comfort and speed though, but those green trays would make a great spot for batteries and other electronics.

Here's the standard unsuspended two seater with some electric assist

So how hard would it be to weld a frame like that? Is it better to buy a fully suspended trike to use for parts, or is it just something you can jump into using recycled bicycle parts?

That frame looks like it is entirely bolted together, so you woulnd't *have* to do any welding to build it. It may be using one of the various "systems" for building stuff from tubing and connectors, or it might be entirely scratch. If it's one of the systems, then while it might cost more for hte parts they're designed to be easy to use an dput together. If it's from scratch it might be cheaper but take more DIY to make it all work.
