    Dedicated E-bike Downhill/Freeride frame and build

    so what every happened to this project? all photo links are dead, blog is dead, and youtube channel doesnt' even show a clear shot of the frame. maybe original creator could release dxf files and give others a crack at it. Seems like too many bike projects die and with them all the knowledge of...

    Homemade Battery Packs

    they have 48v panasonic packs that are 2x the capacity 300w for $40, so you "save" $20 by tearing down and putting your own pack. for me I"m just lazy and got those panasonic packs.

    Custom USA made hubsink heatsinks for any diameter hub motor

    I don't think so because the rim is attached to the motor and there is a big 50mm gap beween the two. It will only fork for direct hub motrs, not motors with integrated rims. sorry.

    Custom USA made hubsink heatsinks for any diameter hub motor

    Also can make the hubsink out of 0.75"x1.5" Tube with 1/8" thick walls. This would be a single heat sink and not a pair of heat sinks. This is closer to the original hubsink specs see below Original Hub sink: Our Hub sink: 2.0 sq/ft surface area 1.52 sq/ft surface area 15mm sink width...

    Custom USA made hubsink heatsinks for any diameter hub motor

    $40 for two heatsinks that are each 1"x0.5" in size with 0.093" thick walls. Just let me know the diameter of the hub you want to put them on. Each pair is custom cut and non refundable. There will be a slight gap between the start and end of each one which allows the screw to be tightened...

    8020 Aluminum Recumbent Frame?[UPDATE: It works!]

    True, but you wont' be changing it much once you settle on a final design. 1x3 T slot is 1.333 lbs/ft hollow aluminum tube of same dimension is 0.54 lbs/ft. it's like 2.5x heavier. if you want to save 10 lbs at least change the 2 main long pieces to hollow tube.

    8020 Aluminum Recumbent Frame?[UPDATE: It works!]

    no chain? 80/20 is just as heavy if not heavier than hollow steel tube. I used to use it a lot, but after doing weight analysis found out it is pretty worthless for making bikes out of. ocassional I use very short pieces of it.

I will add some jb weld on the bottom part of motor to fill in the gaps so I will not need to use...

    DIY Phaserunner heatsink.

    I just used a copper computer cpu heat sink and drilled 4 holes in it added thermal paste and bolt the PHase runner to it. I bent a few fins, but it works fine.

    Cheap hub sink?

    if you have a wood miter saw with aluminum blade it is pretty easy to do. heck one could even do it with a grinder or a hack saw (your arm would be super tired!) buy some aluminum tube with about 1/8" thick walls. Make sure it is 6063 alloy not 6061 (does not bend easily) Lets say you use 1x1"...

    Re-volting the eZips ... Simple Mods!

    thanks I've ordered the 13t motor gears off ebay. I'll test those out and see how it goes. with cheap battery sources like www.jag35.com and www.batteryhookup.com I'm too lazy to build a battery pack. I'll just buy a used one for cheap and add a bms if needed I can solder a dozen leads, but...

    Sources for E-bike Frames

    I just got some izip mountain trailz aluminum frame ebikes for cheap off facebook market place. they are easy to step through and have a rear cargo rack. but you can use any step through bike and add a rear cargo rack pretty easily as well. good luck.

    One stop for solar charging ebike info?

    I got these MPPT charge controllers from China. They took a small order of only 6 units. they are designed for gold carts, ebikes with 48 or 60v battery packs. Big aluminum extrusion Not as small as the $200 Genasun units but they were $17. for that price I'll take the extra 4 lbs of weight they...

    Who sells hub motors with L10 connectors Besides Ebike.ca

    IT IS 12GA wire which has 40ampacity rating. Many ebikes dont' go past 25amps under normal operation. so I am puzzled why you say it is not suitable for high power? Their peak claims of 100a for short periods is kind of ridiculous thoughl

    Who sells hub motors with L10 connectors Besides Ebike.ca

    Who sells hub motors with L10 connectors Besides Ebike.ca? in the USA? I like how the L10 connector comes out the side of the motor and not through the axel and also like how compact and neat it is.

    One stop for solar charging ebike info?

    I am putting together a system using 4 sunpower 170v panels which will make a roof above my trike that is about 4x10 ft in size. I'd make it so the panels can be taken off easily and they would probabaly fold in half so 4x5' for easier storage. they have a 2 year mechanical 5 year output...

    wouldn't making an aero fairing give you more gains than the 7% tracking feature?

    Around the world on a solar ebike

    very cool build. I was wondering why I dont' see any aerodynamic trikes compete in sun race a 680W 4 panel trike about 4x10' in size could probably cruise at 15-20mph with no battery pack on a sunny day. I see 1000w solar cars made by high school and university students all the time, maybe it is...
