Winter project done - Titan/Nuvinci on USX trike

[cgbjake]

Well, I got it done. After obsessing over the winter with this, I've completed it. I'm a little disappointed with the performance, I was expecting a little more speed. With soft tires I've gotten 31 MPH out of it. I'd like to see 40 so I don't have to have the throttle wide open the hole time to cruise at 25-30, thats fast enough for me. I tried putting air in the tires, we'll see how that goes. We are expected to get 2 inches of snow tonight so I'll have to wait until Wednesday. Here are a few pictures. I tried to document a lot of the specifics, I'll post them later. Does anyone know where to post a journal of the project besides here? Hope you enjoy and get more ideas off of it, I've gotten so many off of what I've read here and other sites. Who has the next good idea?

Goblin, Goblin, where are you Goblin?

Looking for GoblinAero...would like to compare thoughts. Your trike is the closest that I've found on here and gave me a lot of ideas for mine. Are you still lurking around here?

It looks like you've got lots of low end power. Maybe try a bigger sprocket on the output shaft? I'm running a bit more power than you, but I'd think you should be able to cruise at 35 with the correct gearing.

Nice build.

hi cbj jake,

that trike turned out to be a beauty congrats on the build,

and as for goblin, holy smoke have you seen his site lately, he has some serious stuff going on, i think his time with us was a short one !!!!!

 

[cgbjake]

WOW, Goblin has some serious buisness. I wish I could do R&D like that. After cruising 40 miles in less than warm weather, I'd love one of those. Even a home made plexi glass would help.

I'm thinking there is considerable power loss with the Nuvinci hub. I can't get above 32 with pumped up tires. I know I'm a big guy, 210 lbs, but I thought it would get a little more than that. Any idea of the calculated power loss?

smaller motor?

has any one put a smaller motor on the usx? I want ot install one UNDER the seat.

hi jawnn,

you get what you pay for, right !!! what else to expect from a $600 trike,considering the good quailty starts at around $2000 + .. just sticking up for the delta ax i have electric and honda engine and many happy hours of cruizing around.

have you surfed around much yet, clearance issues are going to be your biggest problem underneath most of the available kits are designed to be mounted of the rear of the trike and probably the easiest route for you although you would have to reconfigure your storage......
