Re: 2000 Honda Insight: Convert, or No?

Hello All; This is a very old thread, but I feel the need to update it because it's taken a long time for the ultimate answers to become apparent: First: Eventually, I replaced the catalytic converter with a genuine Honda OEM catalytic converter. I got that part from majestic honda in Rhode Island (...

Re: Leaf 1000W on a Tour Easy recumbent

Arrgh, it is now so hard to limit my riding to 20 mph for the efficiency test. I have gotten used to 30. How am I ever going to go back to a regular bike, where I used to feel good when I could average 14? BTW: I know I suggested 20-23mph, but that's the "sweet spot speed" I see on an upright bike....

Re: Leaf 1000W on a Tour Easy recumbent

Thanks! I have gotten back and forth to work three times on one charge, about 52 miles, without any particular care. The power gauge was low but it is just a series of bars and I don't know exactly how close I was to running out of power. Over the course of the next few days I will try to measure e...

Re: Leaf 1000W on a Tour Easy recumbent

I now have about 500 miles on my build completed in April and everything is working well enough that I am ready to call it a success. Original bike: Easy Racer Tour Easy, vintage about 2002. The only major upgrade was the back rim about three years back – most of one’s weight is on the back wheel a...

Re: Hi-Efficiency Recumbent Commuter Conversion

Hi veloman! Hi 1kw! I still have plans to build a LWB recumbent ebike. I want to go with a lightweight, direct-drive rear hubmotor (like the little 9c that GrinTech sells now). I'm thinking somewhere around 500-1000 watts. I have no plans to convert a SWB in the future and I'll likely strip the fram...

The Poorest-Written Ebike Article...Ever?

http://www.techinsider.io/the-oko-electric-bike-launches-2015-10 Compliants: 1) The BATTERY is in the middle of the frame, NOT the motor. The motor is a front wheel hub drive.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I installed one of these 1500W leaf bike motors on a NYX frame with an Adaptto controller as an ebike build for my wife. I seem to be unable to notice a difference in acceleration between the normal and boost settings (boost is ~100A phase higher), so it seems to be into saturation already. When I ...

Agreed. Does the location of the pin prick matter? I did the outside cells in on the flat sides and the inside cells on the edges.

Well, I'm kind of reckless, just be aware that if you stick that needle in to far the pouch could ignite on you. So be very very very careful not to do that.

Depuff means I took a small straight pin and very carefully poked a hole in the foil punches to squeeze most of the air out of them and then took some packing tape and closed the hole. Thanks Wes!

What is modern? I love Troy's design. . Strongly agree. In fact, I was lamenting the fact that he couldn't go MORE classic and use a fully lugged frame (with the special headset, of course). If simple, straight handlebars are more "modern", then I'd agree with that. I'll always vote for simple hand...

Re: Mopeds in NC Now "Registered"

The way I understand it from a bud of mine who lived in Europe for about a decade, is that they register, and insure, their bikes there. (Insurance against both liability and theft/damage/destruction, I think?)

Anyone on the forums in Europe care to comment about this?
