Will do! In the meantime...I thought I'd answer a few questions that are still outstanding.
You know, I'm fine to keep the trailering/Siena speeds to 10-14mph w/ 18 as an absolute cap. I can't really imagine wanting to take Siena much faster, I doubt she'd feel comfortable and I'd worry more about sudden stops, unexpected issues requiring quick response, etc at higher speeds anyway. Not only is she our dog...part of the family...but her function as a service dog is extremely unique and losing her would be well, just not an option right now. So, I like the lower speeds.
Having said all that...what would you be thinking as max speeds for the entourage of me, bike, dog in trailer if it was the Origin8? I just am curious of your perspective of the difference in the tolerances between the bikes.
Secondly, we DID go looking at other bikes today! Went to a couple of other LBS's, Steven test rode several different types and I test "sat" on several of them. This included what was my original "holy grail" bike style, the crank forward. I'm SO GLAD WE TOOK THE TIME TO DO THIS! I was feeling a little unsure last night about everything...just in terms of bike style, etc and wondering if falling in love with the Dahon's was a "fluke". Well, it wasn't. The more bikes we tried (via our two methods...me sitting, trying out different seat positions and where that made my legs go on the pedals at both extremes) and Steven whizzing around the parking lot dodging other test riders...the more we came back to loving the 20" Dahons. So, I feel more confident than ever that 20" is the way I want to go (leaving Steven the opportunity to speak for himself...although the impression I get is that he wants a Dahon ASAP
Now, question for you. Do you have any other measurements of the Origin8 bike (particularly standover and wheelbase) than what is on their website? I'd really love to be able to compare the two equally in that respect. Also, reading the ebike mod of the other Dahon was awesome. I'm not all the way through the thread but it's super cool.
And now to @warrah (does that work on these forums?). I really wanted to thank you for your post. Reading through this thread an picking out those questions that had been lost in the barrage of questions that I've had was really amazing and I appreciate it so much. I also appreciated hearing your perspective on the different engines and how to "trick" out the DD if that's the way we go and also your perspective on the reason for making a custom ebike - because ultimately, it's to get the components that I love and figure out how to make them work together (like keeping the speed down). So, thank you for taking the time to share.
