Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

But when we used weight lifting gloves that only covered the palms and were held in place with a thin strap, it made a huge difference. Great idea. I'm going to start posting sketches of the rowing mechanism I have in mind next. But basically, the idea is that the legs will be pushing on the pulley...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

it's just because the THYS rowingbike is recumbent and has a smaller aeorodyanmic footprint. If you go back to my original posts in this thread, the motivation for having a rowing option is to mix up the exercize so we're not just sitting there spinning legs all day, rather than any specific effici...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

Question number 2? For a normal human, what is the most efficient bicycle design? Pedal or rowing? I want to transport my self 10 miles as fast as possible, using as little energy as possible. Should I buy a pedal or rowing bike? No hills but lots of wind. Pedaling is more efficient. On a flat road...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

I definitely had calluses on my hands when I was riding my rowbikes. I also wore bike gloves. Most regular folks can produce about as much effort through their arms, as they can through one of their legs. On my setup, I could adjust the kevlar cable attachment point, on the steering riser, so that t...

Re: My recumbent cargo bike

Winter here in central Virginia was total crap. Cold, and or rain...worst winter in a decade. I was 55 days off the bikes. There were about five decent days in there, but I had cold and/or flu for all of them. Six rides, on this bike, since 03/29...466 miles, 15,727 mi total, so far.

Simple solution? Shrink the size and weight and speed of the vehicle (see "ebikes").
Bingo!

Re: My recumbent cargo bike

I was surprised to see how long it has been since I posted to my cargo bike thread. I've ridden it 1,100 miles since September, which is low for me, but the last month and a half have been crap for riding. This week, we appear to be back to our regularly scheduled, warmer than average weather. Yeste...

We are, in theory, on renewable power. Some energy trading scheme our electric coop found. We are paying 10% more to support somebody's "green" energy. Still waiting to be able to "buy" PV panels, that our coop will be installing, to offset all future energy use for this house, in their "solar garde...

The pack is hanging in there, still OK pulling out 20 amp hours. I have no inside track on the the new cells. Paul, at EM3ev might know. Rode the RANS cargo bike today...63 miles. Bikes are the best!

We hit 7,500 miles, 50% further than our old gassers, in six months, proving the Jevons paradox. It is so fun, cheap to run, and not spewing smoke, it makes you almost believe it is "green." With the frigid weather we have been having, running the heat, we got the lifetime Wh/mile to go from 250 Wh/...

Today was my first ride in a month! We were stuck under the polar vortex, but it seems to have moved on now. Saw three runners, and a ripped young gal on a MTB. Probably all UVA students. Also saw a Tesla Model X, of course. Getting within ten miles of Charlottesville, it is almost guaranteed. Did t...

Re: Anyone use fairings? Why not...?

The problem with a fairing is that it adds weight and bulk to an otherwise very basic vehicle. For me, and most people, we don't generate enough speed to make it worth hauling up hill. Had a Zzipper on a V-Rex back in the 1990's for one winter. Great for wind chill reduction but amplified noise, and...

If so, then its commercial success (or lack of such) points out the rather weak cost benefits of fairings for most riders.
It points out that upright bike riders are the most conformist people in the world.
