    Electric Vehicle Celebration Day July 9th

    I don't know about a Tesla but I saw my first Nevco Gizmo at the EV Awareness Day five years ago. Fell in love with it at first sight. Took seveal years but I own a year 2000 model now. Number nineteen. I would enjoy attending again. It all depends on my work schedule. Bill

    Portland, OR: Meet and Greet...

    Saturday is the bigger of the two days in my opinion. Gates open at ~8:00am. First race last year began around 11:00am. I looked for a race schedule for this year but it has yet to be posted. The HPC is in less than two weeks and the website isn't finished, Wow! Looking forward to seeing your...

    Phil, would you be able to bring your Twike by Portland International Raceway (PIR) on Memorial Day weekend (May 28-29th). Many of us at OHPV and in the HPV world would enjoy seeing it. Might be a few other veolomobiles showing up. I'm debating on whether I bring mine or not. Bill

    I had a great time. Many thanks to Greenerwheels and Neptronix for you work. Thanks Steve for the use of your chair. I'll need to bring one myself next time. Bill

    I'd be happy to bring my velomobile. I have an invitation to attend an Earth Day event up around Seattle but the PSU event is easier to do on a work day. Sun Coaster, please post the link to the new Earth Day topic post

    I just received a reply from Sunrace Sturmey Archer about the minimum chain ring size allowed.

    You got me there, I'd forgot to include that link also. One thing to not for the metric challenged is that the hembrow link is only in metric whereas the web archive link has the ability for bot metric and "Anglo-american units" The hembrow link has more velomobile types to choose from also.

    Warren, are you familiar with the Bicycle Speed and Power Calculator? The original site is no longer online however one can still access it via the web archive's Wayback Machine. Here's a link to the calculator...

    Warren's 350 MAC mid-drive (finally) recumbent

    I just checked my parts inventory and I have an 18t freewheel and a 60t chain ring. That will get me a 3.33:1 ratio. I'll have to get the e-assist reassembled in the velomobile and give it a try. Bill

    Warren's 350 MAC mid-drive (finally) recumbent

    Thanks for posting the flickr set link Warren. I see he was also using a 13/44 combo for a 3.38:1 ratio. Perhaps I should have used a smaller freewheel like you mentioned :D Bill

    Warren's 350 MAC mid-drive (finally) recumbent

    I'm interested to know where you're getting the no-load 356.4 rpm for a 408 motor. It could be that I'm not understanding but according to the ebikes.ca simulator http://www.ebikes.ca/simulator/ the 408 motor has a no-load rpm of ~290rpm. If that's the correct number than I should be targeting a...

    Warren's 350 MAC mid-drive (finally) recumbent

    It just dawned on me that the 2008 E-S link I posted about the e-Power Challenge was or could be misleading. That link was about when I was running a C'lyte 406 hub motor in my rear wheel with a 48v 18Ah SLA pack. In April of 2009 I was building my bottom bracket drive for the May 2009 race...

    Warren's 350 MAC mid-drive (finally) recumbent

    With my bottom bracket drive I'm using a C'lyte 408 motor with an 18t freewheel and a 46t chain ring giving me a 2.55:1 ratio. I'm trying to run the motor at peak efficiency. I believe that would be ~260 RPM for the motor. All that was new to me back on 08. Perhaps the 3:1 of a 16/48 combo would...

    Warren's 350 MAC mid-drive (finally) recumbent

    No internal geared rear hub. Just an 11-34 cassette. My bottom bracket is a Schlumpf high speed drive. http://www.schlumpf.ch/hp/hsd/hsd_engl_ausfuehrungen.htm It's an internal geared two speed bottom bracket with a 2.5 overdrive. The chain ring is 27t and in overdrive is equivalent to a 67.5t...

    Warren's 350 MAC mid-drive (finally) recumbent

    While pedaling only without the motor running it (the motor) doesn't spin due to the single speed freewheel mounted on the motor. With the C'lyte motors I have there is considerable drag IMO when mounted in a wheel and pedaling only without assist. This is the setup I have in my velomobile...

    Warren's 350 MAC mid-drive (finally) recumbent

    I'm a little late to the thread but wanted to say that I use a C'lyte 408 with a 36v 20Ah LiFePO4 Headway battery pack driving my bottom bracket. Speed wise it'll do just under 30mph at under 14Wh/mile with a 44 mile range running wide open. A friend of mine who has a Stokemonkey gets better...

    Whats your top speed with 48 volts?

    In 2008 I raced in the ePower Challenge with four 12v 18Ah SLA batteries (48 lbs) and a C'lyte 406 hub motor in a 26" wheel. The track had two feet of elevation gain and something like 12 corners that killed time due to wheel scrubbing of a tadpole trike. My race results were as follows; 4 12V...

    I too had a great time. At the event I was remorseful that I didn't bring my bike. Yesterday, I had my dog euthanized due to kidney failure he was 14 years old Pomeranian and haven't been in the mood for much of anything. Hopefully we can get together again sometime soon so that I can...

    I should be able to attend the meeting. My velomobile needs some work on the electrical lighting system but there's always the "Gizmo to fall back on as long as I charge at dnmun's place. Bill SE Pdx
