Re: Aerodynamics

Typically most car drivers can't see my recumbent until they're within a mile of it and don't pay attention to it until they get within a few blocks, or so they say. Unloaded @ 25 mph with some pedaling going on, around 12 Wh/Mi. Coming back from the store with six or eight bags of groceries and a b...

Re: overclocking 1000W 48v direct hub on 24S?

I run 18s on a GM 901, with a Lyen 18 FET low RDS. Works pretty well, as long as I don't run it past 4000W often or long. For your stated purposes, a Cromotor or a similar one is the way for you to go.

Re: Etrike Touring

I've done more less coast to coast round trip twice. Lakewood WA to Quantico, VA and back on a trike and Portland, OR to D.C. and back on a Velomobile (Pterovelo). No dog though and I got rid of the trailer for the run back from Quantico. This is what the trike looks like today. Everything can be ch...

Re: Tri This: The Official Tricycle Thread

I went the cargo trike route with my Catrike Expedition. The HS3540 motor is a bit obvious but everything else is pretty well stashed out of site to the casual observer. http://farm9.staticflickr.com/8498/8429631465_b32dbd6063_c.jpg I'm considering either a Fiester WAW or Greenspeed Glyde velomobile...

Chalo,
From all that you've said on the subject, your knowledge of velomobiles could be stuffed in a Coke bottle and not obscure the bottom. If you're not a troll, you're doing a damn fine imitation of one. :roll:

Re: Sexy Practical Velomobile?

Once I ran the tread down on the Schwalbe Marathon Racers that came on my Catrike Expedition, they got swapped out for 2.0 Big Apples on the front and a 2.35 BA on the back. They make the ride feel like there is about a 1.5 in. suspension on the trike and once the cargo extension got put on and the...

Re: Catrike Expe Ready for Tater TOT

I like your cargo bay. It hides the hub and keeps things looking clean. I have it cinched up a bit, so it would show in the photo. With a few items in the bags, like groceries or something the bags completely conceal the hub. I popped the side cases, gave it two coats of Urathane and drilled the co...

Re: Enclosed pedal electric tadpole trike

Velos and whatnot are all well and good but for me my trike with a XT fairing does very well. When it isn't carrying home the groceries it has been an excellent touring machine.

Re: KMX Typhoon: tadpole trike is on the way!

Tadpoles are terrific electric builds. Since your trike is evidently used, you need to check the toe in/out of the front tires. Because of the frame flex, you need to do this with your weight on the trike or have someone give you a hand. You need the front to be as close to dead on as you can get it...

Re: Best way to true a motor shaft?

I used to true shafts that were as much as .090 out. The trick is to put a dial indicator on the shaft and turn it to its highest point. Then apply heat to the top part of the shaft until its nearly Red. Take the heat away and blow some air on it from the compressor, to help cool it. Metal has a mem...

Re: Crystalyte NEW HIGH POWER hub motor...TheCrown

If done right, I like the idea of straight pull spokes. The elbow at the flange end of "normal" spokes has always bothered me. How they attach the straight spokes to the hub is what concerns me. Keeping a wheel properly stressed and true could be much better given the beating these take every day.

Re: Looking to take the plunge!

Get a used Catrike Road or Expedition. Just put the battery in one of the frame bags. Groceries go in the bags on the rack in back. A trike tends to get better Wh/Mi then a DF and you get fall over insurance free. If you need a suspension, just put Schwalbe Big Apple tires on. Its about the same as ...

Re: Useful tire information from Schwalbe.

Over the last seven years that I've been keeping track of wear on the Catrike, its been around 3500 mi. on the rear tire, with front tires only going around 2200 mi. Usually the fronts die early because of the hard cornering. I think DFs might wear more evenly, front to back. I run Schwalbe Big Appl...

Re: determine the correct spoke tension

I use a Park TM-1 Tension Meter on my wheel builds. An old CSM wheel builder once told me that if I had nothing else, to go by the pitch of the spoke, which should be F Sharp (F#) on nearly any build. A guitar tuner from your local music store could be in your future. As always YMMV.

Re: BB Direct drive motor vs. hub style motors

I have both the GM Pro 901 and the C'Lyte 3540. The Pro 901 takes a screw on type disc rotor. While the C'Lyte uses a standard disc rotor. No idea how well they work as I don't use a disc brake on the rear. On the flats in FL the efficiencies of a BB or mid drive are negated by their mechanical comp...

Re: Connecting Wires

The batteries that I buy come with 5.5 mm bullet connectors, so that is the way I go normally. Phase and Hall wires get Andersons, the rest of the connections like throttle, break regen, cruise etc. get JST-SM plug connectors. As always YMMV
