I think you are right on this. The Eco Exo was never designed for the parameters you want to use it for. You know I did just about everything you could do to one and I even have a wider track than stock! It works very well within its limits but your application is outside those that would require a totally redesigned vehicle to run at the speeds you want. I had a Davis DA-2A Homebuilt airplane that I put over 2150 hours on in ten years before I sold it to someone in the UK. It would cruise all day at 135 MPH and saw 160MPH many times on a descent. So I also am used to fast things but the Eco Exo is not a race machine or fast touring machine on the Autobahn.
I guess that is all I can say on this subject. From my experience on mine there is no sense beating a dead horse on this one.

Hi Dave,
The guys here are right the Eco-Exo is not really a 'speed machine' if it were then it would have been designed around a different donor entirely. The RS will be different to the Eco-Exo but it will still be along similar lines. I'm not averse to the 650 and am on the lookout for one but don't hold your breath.
Trust me I've driven at over 150mph a fair few times and that's in a car that's superbly balanced, as much fun as the Eco-Exo is I wouldn't recommend the sorts of speeds you're looking at in one. Given the sorts of speeds you're talking about I do think that the tR1ke might be more suited.

The An400 engine is a good choice for the Exo IMO. It accelerates pretty quick and top speed is real world but not for track use. Nothing wrong with that exept availability over here... I may even like a lighter engine and more fuel savings for a comutter. looking forward to an RS sneak preview already!

Dave
On a final note, let me tell you where the Eco-Exo really excels. I know Washington state has thousands of side and back country roads. You have small towns dotted between beautiful twisting and winding country lanes. Endless halls of pine forested roads leading everywhere. The Eco-Exo is a superior machine for this sort of riding. Not every ride should be at high speed. What benefit is it to tear through these beautiful byways at a 100 MPH and only see a blur. Maybe it's my age, or perhaps I have come to the realization that a I am no longer 10 feet tall and bullet proof. My enjoyment is now allowing time to smell the flowers. My days of " Doing the Dime" have come to an end. The Eco-Exo is the perfect transportation for this sort of mind set and driving enjoyment. It is responsive, peppy,economical, and tops out at around 80 MPH..

Ok, I am not asking for a fully built kit. All I want posted is that I am looking for an unfinished or damaged kit. I do appreciate the warnings and all but I would like this post to be just about finding a seller that got in over their head or crashed a kit and does not want to rebuild it. My plans are to widen it some, use maybe Corvette C5 suspension/disc's. No steering wheel or handle bars, just a twin stick push-pull design.
So if I could, please get this topic back to basics, thanks. Dave

Dave, the Eco-Exo is less than a fifth the weight of a C5. I really think the tR1ke would suit you far more

Dave, Back on track, you won't find a Damaged Eco-Exo! It has 100% safety record - That both I and I'm sure Kelvin will want to keep,,,,, With all the changes you propose, I know you would be better finding an alternative chassis, oh and forget the "stick steering" there is a video on the web of a vehicle with that  ? dangerous IMHO, Good luck with the search,,, Scott |

Handle bar vs stick steering. What's the difference? It's only 90 rotation of the handgrips right in a more comfortable position or...?

Here is a well thought out trike with twin stick steering, Link below. While it takes a bit of learning, he has no problems. On my motorcycles I am a firm believer of counter steering. If I want to go right, I push the right handle bar forward. The harder I push, the more the bike leans into the corner. Same with the twin sticks, push the right stick forward and the trike goes right. Twin stick only works on a light weight trike. reversetrike.proboards.com/thread/562/new-old-trike |

I've seen that trike and vids and it's a great homebrew project, However, I think the original Eco-Exo steering bar exells in simplicity with less ball linkage free play. It should be a no brainer to lower the stering bar recumbent bike style  |

Well spotted! Only Dave is in the USA and this one is in Redditch England so it's a bit of a trek but as can be seen from the advert even the 250 "goes like the clappers" |

Iank, thanks for posting that kit. But yes I am in the Seattle area of Washington USA. With shipping at about 1000 Pounds and the cost of the kit I am looking at $4650 to get it here. I can get a 400 kit from Kelvin at about $4900 shipped so it would still be a fair deal to pick up this kit. Maybe a local on the sellers side could find out how much being a buyers broker, crating and shipping would be to Auburn, Washington 98092. I may still do this.

Well, it looks like I may be going the EV route. I may be ordering a set of plans from Stuart for his E-Bike and modify it for front electric hub drive. I can get two 15KW hubs mounted in an aluminum 13 inch rim for $650 each and 20 Kw ones in a 14 inch rim for $900 each. Batteries are Li/ion with a Mosfet controller on each battery and with enough cells to give me a 160+ mile range @ 70 MPH and a top speed of 85 MPH will cost $2000. My costs will be high for the build but the pay back will be in the ride as it will cost $0.20 a day to charge it for a 160+ mile ride. I am currently commuting about 18,000 miles per year and my Burgman 650 cost me in gas and oil/filter changes about $1450. In that same 18,000 miles the EV will cost me less than $35. My commute is 75 miles round trip so I will be at 40-50% discharge and the $0.20 a day charge is based on a 80% discharge and I can go two days on one charge. Still have to buy tires but they are cheaper too. No oil/filter changes. Insurance is about half for a year. Here is a scooter using the 15 KW hub. zelectricvehicle.com/22.html |

? dangerous IMHO,
