13HP Reverse Trike

[Rotore]

I personally think you should have a rollcage.

and a cup holder.

you guys basically described a t-rex or miniture version

So do I.

Good luck with the build, by the way! Something to notice (if you didn't already) is the inherent issues with the configuration by design alone. Watch the guy make his corners. Limited distance, limited speed. And he dips the frame into 2 wheels in multiple instances. Secondly, due to what I'd assume is all the functional weight being in the rear of the kart, the rear drifts from the drive tire breaking loose from the centrifugal force applied from a turn.

Not to blow turds on your idea, as it looks like it can be a regular hoot to drive. But be aware, this thing is going to be squirrelly as hell in the corners, both from torsional and centrifugal forces. Great on the straights, though. And given your powertrain set-up, what you have available as far as parts, and the similarities between the builds, I think you'll find a 4 wheel cart with a balanced weight profile will give you the best of both worlds. Power and speed, but with the stability you'd want with a road cart.

stop tryna shot down his ideas for a road cart it should be extremely fun to drive. besides he's basically building on the same principles as a t-rex from what i saw in his design he should be fine. But i do agree with the roll cage comment

Its ok guys i welcome critisism and comments alike, after all its is these that spawn new ideas.

The reason i wish to build a trike is to be different and stand out from the rest. The bloke i linked to used a regular kart frame modified into a three wheeler, those karts are meant to flex. Mine will be solid. I will consider the roll cage, but will definetly adapt it to have a head rest pole type design higher than my head if you think it is necesary. I will also have a seat belt.

Again i welcome comments so please, keep them coming!

 

[Rotore]

seriously recommend the roll cage it wont only be different but it'll look good also be safe dude.

BTW how high will it be from the ground? Would look better low and helps the trike resist rolling over.

but either way it's a great idea and use that picture of the t-rex that i posted as a reference should come in handy.

either way good luck

Most likely about an inch of clearance for the main chassie mate.

 

[Rotore]

very nice dude keep me posted heres a video of what i was talking about: http://www.youtube.com/watch?v=38TFetQAe2o&feature=related

 

[Carlman]

Yea seen it mate its what inspired me into this design, i love the fact that i can drift so easily with a reverse trike, thats basically what this build is about.

Glad you like the design mate!

 

[Rotore]

drift would be insane on it. it'd be kind of cool building one i might just convert my cart j/k but the design is awsome glad someone thinks outside the box lol.

heres something i drew up to give you an idea of what i ment with the roll cage (sorry for the quality ms paint)

Look mate, Tadpole trikes, as they are called, are prone to rolling from cornering at even the most benign speeds-try 25km/h.

People say the exact same thing about Delta trikes, but where do you see that design all the time?

 

[Carlman]

Sweet thanks for the diag, was thinking if its upside down then wont I just need a support behind my head? Just thinking for wieght reasons. Not trying to skimp on safety or anything.

Think about it, a tadpole trike's wheel placement makes it more prone to rolling, especially with green drivers. If you lift a front wheel, whilst traveling forwards and turning, its really really easy to end up on your side or in barrel rolls.

As for the width of those vehicles, 1m hub to hub, and 2.5m long. Unless your trying to build a square, theres nothing wrong with that.

 

[Rotore]

^^^^ exactly especially if your goind to drift it you should go with a rollcage

 

[squat251]

rotor, thats almost exactly what i hope to build, the t-rex powered by a 440 cuyuna, we build a scale model of it, and its incredibly stable, so i think this street cart should do fine.

as for converting your cart over, my friend has a cart with a removable rear swing arm, and he has 3 different rear ends built up that bolt on to it, so he can street race, or mud, and I cant remember what the last one does.

lol it's a pretty unique setup for a go kart no dought about it and when built right it is very stable for a street cart.

and i'm thinking of converting my kart but if i do i'll just chop my frame up and start from skratch similar to the drawing i made but move the front axle back 2-3 inches and get either a bigger engine or mod the hell out of my briggs to take it to the strip. some what like this:

But with the t-rex you hope to build are you going for a one seat or two seat design?

And I tought when I was 13 that I was the only one to build a reverse trike . Anyway: this is mine:

Get your engine as low as possible, because even my kart turned over a few times already. Especially when you hit the rear brake hard, and the rear wheel slips on one side, a trike gets uncontrollable and unstable...

Just won the ebay auction for my 1:1 RAGB with 1" keyed holes.

sick trike dude....

think you could give some specs on it? and why are u using a belt instead of a chain?

nice find.... i just recently traded my briggs for this 8hp 3speed loncin

 

[Kaptain Krunch]

the reason its belt is because he is using a belt tensioner clutch, which i think is better than centrifugal.

 

[Rotore]

no wonder he's using that huge rear pulley

 

[oranges48]

i am making one of these too. starting out with this.

i picked it up at a garage sale for $10 with a broken drive system. it has a steel frame. im lengthening the frame and adding a half roll cage and a custom fiberglass body. using a 50cc engine with transmission off of a kids 4-wheeler. i'm hoping it is considered a moped under Michigan moped laws.

 

[iRenaat]

Yep, you're right!
There's no cheaper and better gokart clutch than a belt tensioner! I change my belt every 800kms, this costs me about 10$, so thats a cheap solution...
Another reason is that when you want a direct chain from a centrifugal to the rear wheel, you'll need a f*cking huge chainwheel, and that is very expensive
The last reason is the fact that a belt doesn't run of the belt wheel that fast like a chain...
