I can't stand it when mechanics cut my cable ends.
I use slicked and stretched stainless steel tandem length cable on my recumbent cycles. The tension makes them unravel very easy every time I need to replace my brakes or reroute the cable, just pulling them out once can destroy a $6 cable.
I have to solder the ends to prevent this.
I file the ends round and remove some of the shiny chromium-oxide (that keeps things from sticking to stainless steel) helping the solder to reach the base metal.
Then I heat the cable tip with a 100watt iron (DO NOT USE A TOURCH! IT WILL WEAKEN THE CABLE) Drip one drop of the acid flux (the fumes release cyanide poison gas DON’T BREATH THE FUMES) from StayBright’s kit with zinc chloride and hydro-chloric acid. Then apply more heat and the silver solder.
Forney’s 6% silver solder with acid core flux maybe a lot easier to use.
I don’t think super glue can hold the cable strands when twisted.

Pedal-Electric Hybrids

This is not one of those wimpy flexable trikes that are too close to the ground. It is a heavyduty electric vehicle:
[]
Power assist is a mater of using a motor barely large enough for the hills even when combined with your muscle power. These must be tied into your drive chain to use the gears, with out them the motor will not be strong enough, and may not be strong enough for heavy cargo anyhow.

[]
Pedal assist vehicles have more than enough power but they also carry twice the batteries so don’t expect to get very far with out the power. These trikes may weigh 2-3 hundred lbs with a power system of 100lbs because a 48 volt motor is needed to drive a combined weight of 4-5lbs.
[]
If your going to live with out a car, you need a cargo box and Plexiglas windshields over the front most people will not be able to pedal so much weight, I have done it for many years with out a motor, and it HURTS!
[]
Unlike an electric car you can save your batteries power by pedaling on the down slopes and keep from killing your self with caffeine and sugar (both hart attack stimulant if you don’t exercise) by pedal assisting the motor on the up hill grades.
[]
Don’t start with a wimpy trike, even my EZ3 trike may not be big enough for a big enough power system. On delta trikes a hub motor on a front steering wheel set at 60 degrees will cause more wheel flop than is good. A trike truck should be built with enough room for the motor to not stick out the rear in plane view.
[]
Lithium Ion batteries need a Battery management system and low voltage cut off. The size limit of motors are 49cc or 1000watts for the state of Washington. As long as your not some kind of hot-roding fool and keep the pedal assist drive train, you may be ok. 20 mph is the speed limit for non-mopeds. But they ‘should’ be registered as mopeds, even if they will need brake and turn lights.

Minimal power systems are essential if you want to be able to pedal these machines when the electricity runs out.

Figure out how fast you move with the weight and grade you need and then calculate the power you need.
=
Speed calculation:
18 front / 34 rear sprockets = 1 to .53 ratio .............
60 rpm’s at the crank x (.53) = 31.76wheel rpm's..............
62.8” circumference x 31.76 rpm's = 1994.82 ipm ..............
Divided by 12 = 166.235 fpm ..........
166.235 x 60 minutes = 9974.117 fph ............
Divided by 5280 = 1.889 mph.........
=
My second gear, with 28 sprockets on the crank, is 3 mph.
=
A 500 watt geared hub motor with 50 to 1 gear ratio is the best idea for 450lbs on a 16% grade.

Ecco-Speed power assist systems are over priced and underpowered good for bicycles only!
However the right size motor should work for any vehicle.

[] WARNING!!!! Make sure your going to have enough power before you buy any thing, I have seen them have to be pushed up the hill because they don't have enough power. Or run out of electricity!!!! You need a discharge meter.

Wool as Rainwear
Oh wool how I love thee, let me count the ways. When dark skis drizzle an ice-cold rain and I’m pumping enough vapor out of my skin to make Gore-tex as wet inside as vinyl would be, wool is the only thing that can keep me warm.
Snugly woven Merino wool, so soft, so warm, so odor free. How I love thee.
When the cold wind blows the icy rain all I need over my woven fur be a loose fitting duck feather vest. With out bulk the sixteenth inch layer of hair is enough insulation.
My arms do not get cold nor do my legs even when my pants are soaking wet. For my hands mittens will do with wool glove liners, wool sox all year round.
Pedaling with out wool in the winter is impossible, no wonder there are so few smart enough to give up their cars when gasoline causes war.
o
Knitted fabric allows more wind to pass threw than woven fabric.
“Wool absorbs more sweat than polyester, thusly will be warmer and therefore will dry faster.” This sounds very misleading, and I don’t think it can much different than Hydro Wick fabric.
http://www.minus33.com/
What I want to know is how it performs when full of sweat or rain.
Lanolin is the source of the antiseptic amino acids, so do not use soap or hot water or dry cleaning, they will remove the lanolin.
http://hydrowickshirts.com/ feels like cotton but is spun polyester micro fiber. Too bright?

"State of the Art" Lighting
http://www.nordicgroup.us/s78/flashlights.html
0
The SST-50 with an OP reflector 20 degree beam and defuser lens to reduce the rings would be the best lite for me. The SST-50 can produce 1250 lumens at its maximum 5 amps, but three run at half amperage will still produce 1500 lumens with out the excess heat that will shorten their lives.
The Chinese light http://www.geomangear.com/index.php?main_page=product_info&cPath=4_41&products_id=138 has a dark spot in the middle of the beam because it uses an SSC-P7 quad die LED. It does not throw well because it makes a wide beam, the wider the beam the less bright it appears. So I want two wide beam SST-50’s (http://martin-led.com/) and a triple XP-G thrower beam.
Now there is going to be a 3300-lumen lamp using a Bridgelux C2000 (http://martin-led.com/)
…only good for electric trikes.

The SST-50, XP-G, XR-E, and XP-E leave no black hole in the center of the beam unlike the SSC-P7 and MC-E LED quad dies.
0bright LED flash lights can best be used if you can figure out how to power them from an external battery, or just use them as they are. Dont waste your money on an over priced "Nite Rder".
0I know of some one that had an expensive light and discovered that it was not water proof, the hard way. So ask!
This is the nicest one I have ever seen http://martin-led.com/ But I am going to wait for one with the new SST-50 LED's.

The vision-x are only 13 oz http://www.visionxusa.com/. The beam widths are 15 degrees euro 30 flood. I would use two 30 degree with a 15 between.

And this one:

My ideal lamp
3000 lumens over a double wide beam to 30ft ahead (the wider the beam the less bright it is) then a longer beam to 75ft ahead, all driven at low enough power to not exceed 120 degree f ???
I want to use two Martin lamps (http://martin-led.com ) with sst-90’s for efficiency but may need to settle for SST-50’s. Or build my own array.

The Ultimate Commuter bike
HANDLING.This bike is designed for easy handling, not for racing. The usual long wheel base bike has too much swing steer and will not turn in such a tight circle.
[]
All this and a motor in a folding frame???What does it take? Easy handling: Relaxed hand position (short reach)7” to 9” of tiller steer No wheel flop (half inch trial)
One third of the weight on the front wheel.Easy balance: Long wheelbase Seat lower than the crank. Seat angle 50 to 60 degrees. Rain protection: Fairing Long front fenderInternal gears (for ease of changing gears while climbing hills).disc brakes. Hub generator for LED lights.36 or more 12 gauge stainless steel spokes.
[]
NOTE:The lower the steer angle the easier it is to turn because the wheel turns on to its side using the arch of the wheel to turn the bike. 0-.5” trial removes the wheel flop. The counter balance of your arms keeps the wheel straight through high speed bumps.
[]
Most recumbent delta trikes use a standard steer fork to save money; set at 60 degrees as a compromise. The wheel must turn on its side because the trike can’t lean like a bike, but that produces wheel flop.
[]
The way to correct that problem is to add more rake for less trail. Best maneuverability can be had by dropping the steer axis down to around 50 degrees and rake the wheel axil to zero trail (or at least half the width of the front tire, to keep the front end from moving up when turned)

This is not a well made machine even if it is well designed. It needs a better seat and disc brakes, and a wider wheelbase to stabalize it in the fast turns. And it realy should have a cargo box!

Tire PSI
Contrary to popular belief the psi of a tire has nothing to do with what it will take to pop the tire off the rim; It has everything to do with how strong the casing thread is. The rubber tread helps but it does wear off a bit. Schwalbe tires may be the best but I don't want to be the one to test a 70psi Big Apple on a delta trike with its lateral stress problems.
