Re: The F3: I've been blogged!

cwah, My sincere apology for not sending a reply. As we were chatting about front forks, I killed both my e-bikes and my automobile, and all my discretionary time since has been of (1) transportation and (2) fixing my means of transportation. Hopefully the info I provided got you close enough to mov...

Re: The F3: I've been blogged!

cwah, I didn't have time to take any pix, but I was able to measure the stock Dahon steerer tube with calipers this morning. The dimensions are: 1.125" diameter 5.55" length, from the top of the crown to the top of the tube where the threaded nut is inserted. So, I'd say it's safe to buy a 1 & 1/8th...

Re: Cycle Analyst To Google Earth Software

Using Windows 7 professional (32 bit) service pack 1, the app runs in that I can choose the CA file and the GPS file, and "Generate". It creates a 0 kb KMZ file. Then nothing happens, even after running for an hour on a < 1MB file. https://lh5.googleusercontent.com/-v1JeTkhw5hg/U1CMSFoFJvI/AAAAAAAAE...

I like the idea, and I like the tool you're using. I just added an idea "power cutoff integrated into brakes". Kind of a no-brainer, but added just to practice using the tool.

Show them love and kindness in return. There can never be a better alternative. Perhaps this is the best approach, but following them at least put them on notice that they didn't get away with impunity. The driver will sweat a few days that you stopped the chase once you memorized the tags, make an...

Re: Help me find a crazy torque commuter bike

My experience (Having a Dahon Jetstream with crazy torque): The geometry is not well suited to massive torque, and it will flip you over backwards onto your back and head. The mechanical solution is to extend the wheel base rearward, but the more you do that the harder time you have getting it into ...

I like the NuVinci N360 a lot for pedaling. I use them on both my e-bikes (see signature). I bypass the electric power transmission issues by powering them through the left side thought :)

Re: Dahon Jetstream - How to get more torque

Be careful with more torque on that bike's geometry. My Jetstream used to wheelie so hard and fast it would flip me off the back. This happened several times because of its geometry coupled with high torque and too much throttle (till I tamed it in software with a CAv3). It flipped me backwards twic...

Re: The F3: Close call, near wreck, preventable damage

I have rim brakes on the rear- work really well and I like them a lot. But they are wearing away the rim side wall too fast (by feel, about 1mm of alloy lost in less than 7 months of riding). I want my rims to last at least a few years each… So, I'm going to try to move to disc brakes in the rear. T...

Re: what's longest ride you had to pedal due to a problem?

My worst ride was on my 120lb Norco A-Line when it ate the chain on the electric drive side. I had to pedal all the way home (7.5 miles) on human power alone.

Next upgrade: Hard to see in this picture, but what I want to do is have the Recumpence V4 drive straddle the rear shock.
