If they are using a "secondary reduction" to do what I do with a single stage then that's more complexity and more weight. I am not experiencing "additional...
Thanks for the link. This looks similar to the Sun freewheeling crank. The motors I'm considering turn counter clockwise so I don't think I could use this. I...
You're reading comprehension is a little bit off andrsnj1.. You were claiming that the only reduction in the Ecospeed setup was the 4:1 of the currie uspd...
Why not follow Draper's doctrine and go with HIS lower rpm motor? You'd need less reduction here as well and the increase in efficiency might give you the...
Oh good finally the fuel needed for a Flame War, been so long since we had one here When you're done selling Ecospeed systems and ignoring the shortcomings of ...
If you insist on going to gasoline try this for being more stealth. I did it and it worked fine. Since you plan to mount the ice near the BB you could use a...
This car looks remarkably like Buckminster Fuller's Dymaxion Car, minus the V8 engine. Now if it were built in geodesic carbon fibre fullerenes sigh,.... Its...
Yesterday I had a discussion with someone who was selling his mountain bike equipped with a 49cc ice motor but he advertised it as an E-Bike. When I pointed...
I have been lusting after a Suzuki 650 Burgman and now I see Honda has a 900cc Scooter that really floats my boat http://www.gizmag.com/go/4712/picture/16433/ ...
No flame wars here. Just giving back some of the same language I got. In CT ice assist bikes are the same as electric ones according to the law. If a "moped"...
This bike reminds me of the Honda Pacific Coast which was never a good seller. This is the kind of bike intended for non-bikers who want to cover up the...
Up here they labeled the Pacific Coast the Silverado and yeah it did not sell well at all. It was supposed to be a poor mans GoldWing but if you want a 2 wheel...
Imo, if you show up at a group ride with something that burns gasoline, stink eye will be the least of it... Slap a BMC/eZee hub motor on the front wheel with...
Has anyone tested their batteries on a regular basis to see what they're really doing? Where I work we have electric fork lifts and tow motors. These use big...
The rule of thumb used by many in the battery biz is to develop charge algorithms that allow them to obtain X number of discharge cycles under an anticipated...
Robbie, you are one of a very few who seem to GET IT!. DON ... From: robbiehatfield To: power-assist@yahoogroups.com Sent: Thursday, October 01, 2009 11:53 PM ...
if you cycled your batteries 40% dod you would get more cycles than 50%. If you cycled your batteries 30% you would get more cycles than 40%, etc. Where do...
It has more do to with education and mindset.. I don't own a car but my neighbors have a car and truck, they keep both tanks full, when the needle goes down to...
I can imagine the next wave of hybrids to be electric propulsion only but with a small gas powered generator onboard. Not like the current hybrids or the...
Since I covered a lot of ground there in that Post which part are you referring to? Trimming is a good idea unless you remove the part you are replying about. ...
I draw the line at 50%.. It's a design parameter that takes into account current battery technology and 10,000+ miles of riding experience. It's ridiculous to...
