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 (...

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....

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...

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...

By the way, I found this link only a few months ago: http://www.recumbentblog.com/2010/05/04/the-greenriders-fascinating-trip/ and their blog: http://www.thegreenriders.blogspot.com/ also: http://www.almanacnews.com/news/2010/04/21/two-aim-to-cross-country-on-electric-bikes All links very old, no up...

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...

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. (probably geared, from the size of it). This error keeps getting reported over and over again in the article, associated wit...

Hello I'm new to ebikes, and new to the forums, but I hope that you might be able to help me. I'm planning to buy a trike cargo bike, specifically a Babboe Big: http://www.babboe.co.uk/cargo-bikes/babboe-big.html They have the option to deliver with an electric motor, but I feel like 250W (the lega...

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 ...

linux mint ( ubuntu fork ) is great, is very useable, and looks nice, but.. Adobe flash would constantly freeze my browser though, videos wouldn't play, couldn't find a VNC client that worked properly with my windows server, and it took a shit ton of RAM.. So i am back to my 100% unpatched copy of ...

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. I tried to puff the section here I was going to poke first by squeezing the cell in other places. I did my puffers at the top along the side under the fold. Pinned it a...

This one: http://bestechpower.com/222v6spcmbmspcbforli-ionli-polymerbatterypack/BMS-D163.html Thanks! It's going to be awhile before I integrate the BMS: I have to effect repairs to my existing packs, and I'm considering some Multistars. But installing it is on the to-do list and I'll report back. ...

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. I just happened to have a straight pin handy. Something sharp and non conductive would be a lot safer. Agreed. I regard this operation as bei...

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! I'll give it a try on mine. They really aren't very bad, but I'd like to try "depuffing" to help me ma...

Also: what's your BMS? I bought a BMS and am considering adding it to my LiPo. Which one did you buy, jkbrigman? (And also interested in knowing which one Wes bought.) This one: http://bestechpower.com/222v6spcmbmspcbforli-ionli-polymerbatterypack/BMS-D163.html I'm thinking about pairing it with Tu...

Troy, I see your kickstarter closed and fell short of the funding goal. I'm bummed. What next? Many people reconfigure their kickstarter campaigns and succeed. Is that in Maxwellmotorbikes future? We're working with investors now to build the first production run within about 4 months. It's good be...

No puffers here, but I haven't even used them yet. Just got the bms for them and haven't got a 24s charger yet. I'm going to cut off the XT90's and replace them with 4mm bullets before I wire them to the bms. I did just depuff a 3+ year old 4s hardcase pack and its held up good for a couple of cycl...

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...

Why not use the Seoul? http://www.citizenbike.com/catalog.asp?product_category_id=1&product_id=48 The 20" wheels will give you an edge over the 16" wheels to reach 20mph. Plus, it's 4 lbs lighter, same frame. Beware: those bikes have six speed 14-28T freewheels. You will want to swap out that freewh...

If that quikbyke thing succeeds after our kickstarter fails, I will kill myself. That's a promise. Oh Oh. QB got a mention on autoglog site http://www.autoblog.com/2015/07/23/quikbyke-qpod-electric-bike-rental-kickstarter/ (Or Glub. Or something. :? ) Lock you slay me. "Glub".... Thought I would fo...

James Clerk Maxwell was one of the pantheon of ancients who created the field (ha) of electrical engineering. I usually name my systems after what I call "the great ones":

Gauss
Faraday
Maxwell
Tesla

I think the heat is getting to people.

WTF?!?!? Never seen THAT before!

cresh, you do a fine job of containing "the powa" of your motor. I'd have a hard time keeping the speed down, until I had a bad accident, or worse....

Just love that EV grin! Low on the 3-spd switch is 25mph(40kph), Med is 35mph(56kph), and High is 42mph(67 kph)! Nice and torquey too! ....(awesome comments here)... Couldn't have asked for a better test run, even if it took almost six years to happen. 8) Congratulations Will! You kick ass, and the...

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?
