Sorry for the dark and vertical picture

In this kind of weather I recommend a rack for the cross country skis.

Here's pics and video of mine:

Current configuration(weighing about 65 lbs with the body installed):

-x1 KMX adult-sized steel frame kit
-x2 Velocity USA 20" rims, 14ga spokes (front)
-x2 Gas Shocks (front, set to 60 psi)
-x2 Schwalbe Marathon Greenguard 20"x1.5" tires (front)
-x1 26" double-walled wheel with 12ga spokes (rear)
-x1 Schwalbe Marathon Plus Tour tire, 26"x1.5" (rear)
-x3 packs of KMC 3/32" anti-stretch 7 speed chain
-x1 DNP Epoch 7 spd rear freewheel cogset, 32-11T
-x1 Suntour XCT Jr. 22/32/44T front crankset with 152mm crankarms
-x1 Shimano Tourney 7sp rear derailleuer
-x1 Shimano Revoshift 7 spd grip shift
-x1 Microshift FD-M42 front derailleur
-x1 SRAM 3 spd grip shift
-x1 SunLite dual cable pull lever
-x2 Avid BB7 cable-pull disc brake rotors, calipers and organic pads
-Lights, cables, mirror, speedometer, ect.

I did remove the body to work on the trike though. I do not know when I will have the replacement ready to use.

Now for something completely different...it looks it anyway.

I dont have a video yet of the corovelotrike, but I got one of the old Carp from 10 years ago,,,45 mph

Where is Reneckistan?

My other ride...

What are those pedals? They look like flip-flops in that picture

I love this build. You're probably going to change the nose though; it looks like it would induce too much unwanted torque during crosswinds that could make you lose stability.

Where is Redneckistan?

Where I used to live, which was South Texas.

I just updated it to Ghettoville, USA, which is St. Louis, MO, where I am currently located.

That's fast.

My coroplast-bodied trike could reach 33-35 mph on the flat with me riding it. I've gotten up to 51 mph downhill when I still had the 28/38/48T front cranks on it. Flat ground cruising speed was about 21 mph.

I'm working on a new body that should be significantly less lossy. My steering bars limit my minimum possible width/frontal area as I have to have room to accommodate them, so my bodyshell should have significantly more area than yours. At best, keeping the stock steering setup, I could get a frontal area around 0.5 m^2 from the looks of things(and that's with having holes cut in the sides to allow the steering bars to move, with elastic boots made to flex in and out as I steer, but to seal the airflow up when I'm going straight).

If I had a rack and pinion steering or tiller steering, and the steering bar clearance wasn't an issue any longer, the possibility of getting a frontal area as low as 0.45 m^2 exists.

Right now it has front suspension and is very comfortable and stable, even over potholes. I can make lane changes at 45+ mph with confidence that I won't lose control.

I will eventually get to 40 mph top speed on flat ground, and a cruising speed of 25+ mph, fully under human power, dammit.

Once reached, whenever I can raise the funds, it is THEN getting an overpowered electric drive system, and possibly an upgrade to a rear suspension, as well as moped rims all around, integrated lights/turn signals, and a roll cage.

The goal is a vehicle that can move like a velomobile with electric assist disabled. When electric assist is enabled, I want it to operate as a pedelec with sports car-like acceleration with a 60+ mph top speed. The efficiency target is 3000+ miles per gallon equivalent and a 200+ mile range at 30 mph with a rider input of 100W and the electric drive providing the rest. Theoretically it's perfectly possible. Getting the aerodynamics right is key, and they're not good enough yet.

Hi,

Do you know Jerry .., use to live in Mo now Dallas? I lived in st Louis around 1990.

35 mph is pretty fast for flat ground and no wind. Yes a suspension is good. I rode on a bumpy bike trail, with cracks across, and it was like being inside and someone kicking the sides of a cardboard box. I put zote foam between the frame and coroplast.

I take it you built the bike from scratch, do you have a write up? I have 28/38/48/58 (4) on my swb bike, 20 inch fwd, runs out around 25-30. I hit 33 on the flat bike trial. I have the fairing loosely mounted in the front, people ask ifI have a suspension, its just the fairing moving.

Yes 40mph would be great. I had one bike 10 years ago that hit 40 mph one the flat ,well the one in the video, but it had a full enclosed top on it. The top made a big difference.

Yes the nose it from Warrens Barracuda mold, and it is too long, I tried it out 20 mph down hill into a 25 mph wind and 23F and was buffeted quit a bit, I want to make a new nose. I find the noses are the hardest to get right. I should just bite the bullet and carve up some Styrofoam make one from fiberglass.

The trike use to have USS and I changed it to OSS, made new linkages. This allowed me to lower the seat 3 inches, its now at 6.5 inch.Its hard to get out of with the oss, trying to get knees out from under the bars. I have no plans for electric drive. The fairing is 16 inches wide.

Do you do any touring in you coro faired trike?

Zote foam over the toe clips, keeps toes warmer on -F days. Bike has studded tires, 700c wheels on a 26 inch frame and 165 cranks, gives snow clearance.

Use math.
