after a few times driving it , one gets used to rpm's and clutch pedal release vs weight ratio. no problems taking off
last run@ 70-80 mph in about 1 city block in 1st gear .

Hi scot, I'm a brand new member here and I was very interested in your design.
My 3-wheeler has a similar VW front axle to yours (probably identical) quite a bit longer wheelbase and is powered by a 920cc Virago Twin, not running yet but this spring it will be f'sure.
Curious about the bike tire on the rear versus a car tire. I will try it with the original bike tire but you are saying a car tire works better. Also you mentioned that you need more tilt on the axle than is standard, to make it go right?
Anyway great work - you have given me plenty of hope - I can think, therefore I can do it!

Can I butt-in? Having tried the widest car tire and the widest bike tire that would fit on my rear driver, each for about 3000 miles, I think I can speak to this. The bike tire was a 170/55/17 irc for sport bikes. The car tire a 175/55/17 bridgestone. No appreciable difference in corning grip or handling. Flat spotted IRC gave slightly better forward traction with a contact patch width of about 3" vrs 4.5 for the bridgestone. Apparently the far softer compound on the bike tire trumped the extra width of the car tire.
However, the width of the contact patch on the bike tire only came after 3000 mi of wear and it was about done. The bridgestone has 3000mi on it, lots of that with tire moving faster than the pavement beneath it and it shows no wear. Spending 225 bucks every 3-4000miles for the bike tire would be an expensive pain in the rear. Could probably go farther with a touring type bike tire but it would not grip as well.

that's what forums are for, we want new builders to learn what works what doesn't work so we can build one and not waste time making mistakes.
thanks scot

Triplethreat, I need the bike tire on the back because the car leans 30 degrees each way; the front wheels stay flat on the ground.
Scot, I want you to say something about the angle of the front end. I plan to just leave it as is, according to factory specs, until I see a problem.

Rapt9, I run a car tire on my 2 wheel BIKE. It is a 165/65 SR 14 Bridgestone Potenza. I can state for a fact it will never roll over onto the sidewall and at the most aggressive cornering angle where I am dragging my lower faring sides, I still have more tread in contact with the ground than any motorcycle tire could ever have. You do not have to take my word on it, there are over 10,000 riders on so many bike forums that have gone to the "Darkside". Just search any bike forum for that term "Darkside". Find a forum you like and ask a darksider to show you His/Her cornering footprint.

on the beetle front axle I used a shim kit to change the angle(camber) I have at least 3 degrees angle maybe 5 to control the bump steer.. with radials up front and cycle tire on back it was scary on black top felt like the back end was going to come around at 45mph and throw ya in the ditch. reminded me of having bias ply tires on rear and radials on front of my 73 cuda I had , it was spooky. the car tire on back makes the trike go down the road straight! and no crawling around.
