three wheeler

what do yall think of this.the pictures r not up to date.it has a different gas tank on it now.it does 40 mph.

Your pics inspired me to sketch this up this afternoon eastwoodo4. As sketched, I envision a chengine with ghostO's jackshaft powering a triple ring crank, then a 5 gear cassette at the lower rear jackshaft and a 1:1 power transfer chain to the axle. I drew in the lower frame of 3/4" square steel tubing because, as designed, it could also accomodate an electric motor in the lower drop frame, between the tubes, also feeding to the forward jackshaft. That lower frame would accomodate at least 4 deep cycle marinebatteries - it is drawn as 18" x 18".

What do you think? I think it needs triple tube springer forks.

looks like a lot of work.you pretty much lost me at chengine with ghosto.to me that might as well be a flux capacitor.lol.but if u have the recourses it can work.thats cool design software.

Chengine is what most here call a "Happy Time" - a chinese built 2-stroke. ghostO built a really nice jackshaft to mate to one of those engines and transfer power to an inside chainring on the bikes crank - Pablo and he are selling it as a kit (see the Sick Bike Parts link to the left).

The design software is just Google SketchUp - it's free from Google, and very versatile. I use it a lot.

thanks for the design info.about the other thing.i think its too coplicated.friction drive would suit your needs.hope i didnt miss your point here

Friction drive is probably the simplest and easiest to implement, I would suppose. Unfortunately, due to my disability I cannot ride a two-wheeler, so to implement friction drive on a trike I'd probably need to put it on the front wheel - I think the issues raised by powering one of the two rear wheels of a delta trike would be a very messy can of worms indeed. Oh, I can envision a method of applying friction drive to both rear wheels simultaneously, but it is little less complicated than what I've already drawn up.

i dont think friction drive on front wheel would have a problem.

 

[eastwoodo4]

ok i just seen a triton.yeah no friction drive on that.need a regular trike

Well, I couldn't find the external domensions specs for a NuVinci hub, other than the diameter being 150mm (5.9 inches), nothing on the width, so I guesstimated from the pics on the Staton site.

I updated that delta trike design in SketchUp to incorporate a NuVinci hub, instead of a 7 x 3 gear/chainring derailleur system, and figured I'd colorize it and add basic wheels to give a better idea of what the bike would look like.

It has become apparent to me that I can't afford to build the tadpole leaner I really want - too many unique shapes/components would have to be fabricated. So, in the interests of getting some wheels I can ride, I've designed this thing. Total materials cost will be about $500, plus probably $200 more in getting tubing bent/welded, wheels on it, etc.

Somebody please give me some feedback - please?

 

[eastwoodo4]

yeah that looks like it will work.600 isnt bad.
