    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    I weigh 200lbs. I'll have to weigh the scooter, but I can lift it myself squatting to pick it up so my guess is around 200lbs for the scooter too. Looking at gearing it for 50-55 then as around town speeds are 45, but people drive 50-55. Probably a jackshaft at the swingarm pivot point and I...

    Hubmonster 94% efficient 7kw NO LONGER FOR SALE

    Looking to electrify a 150cc Chinese scooter I bought. After welding up a new swing arm, this looks like it would work well.

    Autocraft Lithium batteries @ Advance Auto Parts

    Excuse me if I'm getting this wrong, but 3s 8ah for $299 doesn't seem to be that good of a deal for EV use. Wouldn't this be much better than 2 of those? http://www.hobbyking.com/hobbyking/store/__18210__turnigy_nano_tech_8000mah_6s_25_50c_lipo_pack.html

    Looki for XR50 head tube specs.

    Awesome, thanks for that link. It looks like the race comes with it and is not part of the tube, so I'll just need to make a step just a hair shorter than the bearing height to position it correctly. Thanks.

    Looki for XR50 head tube specs.

    I picked this front suspension up cheap: http://m.ebay.com/itm?itemId=251566450323 I've done some quick searches for head tube dimensions and can't seem to find any. I know I can measure when it gets here, but does anybody know of a good link to specs on these pit bikes? Specifically looking...

    Cheap 3S bms needed

    Building a ghettoblaster/boombox/ipod dock for a friend using a Tripath amp and itworks fine off the 12v PSU I have, but I have some old laptop batteries and figured I'd like to make it portable. Anyone know of a cheap circuit or board available? I did a couple of searches and checked...

    Let's talk about brakes

    This may be of some help, a steel front caliper mount do you have a 32 or 36 hole hub up front?

    Time to learn how to run a mill.

    Well the mill isn't up and running yet, but there is an excuse. A Boxford lathe is getting upgraded with a freq drive and new controls.

    Time to learn how to run a mill.

    Mill was $600. A lot better than the average around here ($1000-1500+). The guy we picked it up from had a chain fall to load it with and a cherry picker was used to unload. A few pieces of blackpipe made rolling it around a bit easier, hey it worked on the pyramids. I may take a community...

    Time to learn how to run a mill.

    Will do, I'm converting over a mini Oberon keg to transport my homebrew, so that will be following me. Will do, no code as of yet though. Still figuring it out as I've never run a manual lathe yet, maybe a pendant would be helpful in playing around with the lathe before diving into the code...

    Time to learn how to run a mill.

    This one is my buddies, I just picked up a CNC sherline lathe a couple months ago. We sort of have a community workshop going on between us. It did come with a shoebox full of tooling and eBay provided 3 servo motors / drivers. He also has a freq drive for it. Looks fairly tight, but he's...

    107mph....bike broke in half...nearly died

    Hmm, a couple triangular TIGed plates holding the head, top and bottom tubes together may have helped.

    Big 80-100 RC options

    According to the site, I saw a can length of 55mm vs. 77mm (180KV vs. 130KV)

    Big 80-100 RC options

    180KV is 26mm shorter. Looks like the 130KV is better overall then. More motor, mass, surface area for heat dissipation, and more gearing friendly. Thanks Guys.

    Big 80-100 RC options

    Is the 130kv going to be the best choice for us (vs. the 180kv) in most cases? I see the 180kv is rated for aprox .75 HP more than the 130KV, or is that just because of the RPM increase? Thinking of picking up one of these, do these need bearing upgrades yet? I know I should add glue to the...

    Using supercaps to support/replace battery pack

    What about on my lead AGM powered kart? I have 48v it sits at 50 volts as soon as any power is used. I have an AXE4855p controller that is good for 60v before protect kicks in. What if I just used 3-4 of the $10 2600F caps in series with the AGMs? My motor is series wound so no regen, but I get...

    Using supercaps to support/replace battery pack

    What about a couple of them in combination with LiPo to help hold the "hot off the charger voltage", or let someone regen on a fresh battery sooner, or just soak up the regen faster and lessen stress on the battery? If you put a couple in series with the batt would that help? or is a little...

    ES T shirt

    I was just thinking of wheel with tire and earth, no vehicle. Although the rim and tire I was imagining was a from a bike.

    ES T shirt

    As a continuation of Sheriff Jon's idea, What about a picture of the Earth generated by a bike wheel POV kit. That should meet the geeky factor. Rim and tire could be captured still and Earth overlaid inside.......go to youtube and search POV or LED wheel.

    astro motor battery

    Voltage is voltage, just check the motor and controller you plan on using for the correct amount, or others projects as some can handle more than they are rated.
