SM, you might consider these as well. Sure there are more that I didn't think of. But these are all great builds, especially when you look at the time of building. Not many e-bikes like these back then. Specialized Big Hit FSR with midmount http://i164.photobucket.com/albums/u10/tench8/Bighit/P1000...

Got Gas! moving forward..

Started tacking up the enclosure this morning. Using 1/2 square and 1/2 round tube. found some gussets in my scrap pile left over from a different project I''ll be using for holding the battery pack securely. em3evpack enclosure 1.jpg em3evpack enclosure 2.jpg em3evpack enclosure 3.jpg Ran out of mi...

I pre-ordered. Hasnt shipped, figure they will do so when its officially release-able.

I dont know that anyone has received a unit yet.

I've other things upstream to get sorted anyway. Battery pack and mounting starts tomorrow for me.

Dont forget about regen. A 60,000 pound machine hurtling down a hill @ 60mph can fully recharge a 400v 150 ah pack pretty quick. We were using LTO's on several of our prototype platforms due to their higher c rate. We tried 300, 400, and even a few 700 volt( :bigthumb: ) pack designs during the test...

Bike's completely built. Brakes and shifter all set up, probably ride to work a few times to get the bicycle bits sorted. Weighs in a 30.5 pounds as pictured with pedals, 2.8 tires, thru axles, and the main triangle brackets attached for mounting the battery enclosure. KIMG0441.jpg here's a shot of ...

my bill shipped to the door was 806. Pretty close to a BBSHD shipped to my door. Early adoption usually is accompanied by a bit of an initial price discount. I've been encouraged to provide some feedback if I run in to any issues. Jon indicated they are looking forward to feedback from me (us). Look...

Quite a first start! Welcome! I'm back from the dead...... waffled pretty hard over a cyclone for my build. Ive used a bbs02 with great success in the past, very reliable, well integrated, but kinda boring.... No issues ever with it. This should created better balanced & overall lighter ebike th...

urgh. I'm in. Just ordered one. Chain version.

But the only way to divert eyeballs from facebook is to create something better. There's plenty of other FB groups for people to move to. They might not come back unless our system is better or at least as good. Older internet users like me and you might be okay with forums like this one, but young...

t it turned into something that competes with our forum. I've came to truly hate facebook, Future focus of ES will be to try to get the ES FB users over here :mrgreen: . Will update this thread as things go on with more information on phpbb3.3 or whatever they are calling it :) if you shut down the...

Haven't put a build thread up in a while. Targeted goals: 2kw power , Battery pack 40a continuous capable 26 miles range minimum, Total bike weight(including batteries) of 65 pounds max. Completely water/weather proof Multi surface/condition capable Feels like a bicycle Was looking at purchasing a t...

sold. Have fun with it!

they can ride a spare bicycle!

good info in rake/trail/head tube angle interplay

it is indeed. much rather get it to some one here rather than out in the ether...

have big plans for my next e-bike journey so this has to go.

since i can only ride one machine at a time my rule is only one ebike allowed in the stable.

(bicycles are another story.....)

Thank you sir!

Built this late summer, put a few (maybe 100?) miles on it. Works fine, I just want to build a neck snapper.... E Bike based on a cruiser fat bike frame and origin8 fat fork. Turned out great. Hung some nicer components on the bike as I was planning on keeping initialy, but since have changed my min...

that was ages ago

Bringing up the pack to full voltage. Battery/control enclosure sub assembly together, ready to be bolted into the frame.

powdercoat is on. mocked up. assembling the battery/control box next.

52v/20ah.
fat crusier frame nobody wanted
cheap 1000w hub motor

frame is starting to take shape. Should have the frame all finished by the end of the week.

Lidar is an effective addition to radar sensor arrays in dense urban environments where autonomous vehicles have much more environmental inputs around them to process. For scenarios involving autonomous assistance on highways or interstates, much less information is required to maintain position. Wh...

capacitors? once Pack HV and dc dc contactors are closed, dc dc should be able to supply constant 12v power to the contactors. might be able to energize the caps from in rush current. or a few pedal strokes on a pedal bike. or a faux kick starter on a motorcycle. or hand crank. cap (s) woud have to ...
